• Problem trying to achieve a join using the `comments` contrib in Django

  - by NiKo

  Hi, Django rookie here. I have this model, comments are managed with the django_comments contrib: class Fortune(models.Model): author = models.CharField(max_length=45, blank=False) title = models.CharField(max_length=200, blank=False) slug = models.SlugField(_('slug'), db_index=True, max_length=255, unique_for_date='pub_date') content = models.TextField(blank=False) pub_date = models.DateTimeField(_('published date'), db_index=True, default=datetime.now()) votes = models.IntegerField(default=0) comments = generic.GenericRelation( Comment, content_type_field='content_type', object_id_field='object_pk' ) I want to retrieve Fortune objects with a supplementary nb_comments value for each, counting their respectve number of comments ; I try this query: >>> Fortune.objects.annotate(nb_comments=models.Count('comments')) From the shell: >>> from django_fortunes.models import Fortune >>> from django.db.models import Count >>> Fortune.objects.annotate(nb_comments=Count('comments')) [<Fortune: My first fortune, from NiKo>, <Fortune: Another One, from Dude>, <Fortune: A funny one, from NiKo>] >>> from django.db import connection >>> connection.queries.pop() {'time': '0.000', 'sql': u'SELECT "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", "django_fortunes_fortune"."slug", "django_fortunes_fortune"."content", "django_fortunes_fortune"."pub_date", "django_fortunes_fortune"."votes", COUNT("django_comments"."id") AS "nb_comments" FROM "django_fortunes_fortune" LEFT OUTER JOIN "django_comments" ON ("django_fortunes_fortune"."id" = "django_comments"."object_pk") GROUP BY "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", "django_fortunes_fortune"."slug", "django_fortunes_fortune"."content", "django_fortunes_fortune"."pub_date", "django_fortunes_fortune"."votes" LIMIT 21'} Below is the properly formatted sql query: SELECT "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", "django_fortunes_fortune"."slug", "django_fortunes_fortune"."content", "django_fortunes_fortune"."pub_date", "django_fortunes_fortune"."votes", COUNT("django_comments"."id") AS "nb_comments" FROM "django_fortunes_fortune" LEFT OUTER JOIN "django_comments" ON ("django_fortunes_fortune"."id" = "django_comments"."object_pk") GROUP BY "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", "django_fortunes_fortune"."slug", "django_fortunes_fortune"."content", "django_fortunes_fortune"."pub_date", "django_fortunes_fortune"."votes" LIMIT 21 Can you spot the problem? Django won't LEFT JOIN the django_comments table with the content_type data (which contains a reference to the fortune one). This is the kind of query I'd like to be able to generate using the ORM: SELECT "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", COUNT("django_comments"."id") AS "nb_comments" FROM "django_fortunes_fortune" LEFT OUTER JOIN "django_comments" ON ("django_fortunes_fortune"."id" = "django_comments"."object_pk") LEFT OUTER JOIN "django_content_type" ON ("django_comments"."content_type_id" = "django_content_type"."id") GROUP BY "django_fortunes_fortune"."id", "django_fortunes_fortune"."author", "django_fortunes_fortune"."title", "django_fortunes_fortune"."slug", "django_fortunes_fortune"."content", "django_fortunes_fortune"."pub_date", "django_fortunes_fortune"."votes" LIMIT 21 But I don't manage to do it, so help from Django veterans would be much appreciated :) Hint: I'm using Django 1.2-DEV Thanks in advance for your help.

• Is it possible to call Javascript's onsubmit event programatically on a form?

  - by hoyhoy

  In Ruby on Rails, I'm attempting to update the innerHTML of a div tag using the form_remote_tag helper. This update happens whenever an associated select tag receives an onchange event. The problem is, <select onchange="this.form.submit();">; doesn't work. Nor does document.forms[0].submit(). The only way to get the onsubmit code generated in the form_remote_tag to execute is to create a hidden submit button, and invoke the click method on the button from the select tag. Here's a working ERb partial example. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.commit.click" %> <%= submit_tag 'submit_button', :style => "display: none" %> <% end %> <% end %> What I want to do is something like this, but it doesn't work. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> # the following line does not work <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.onsubmit()" %> <% end %> <% end %> So, is there any way to remove the invisible submit button for this use case? There seems to be some confusion. So, let me explain. The basic problem is that submit() doesn't call the onsubmit() code rendered into the form. The actual HTML form that Rails renders from this ERb looks like this: <form action="/products/1" method="post" onsubmit="new Ajax.Updater('content', '/products/1', {asynchronous:true, evalScripts:true, method:'get', parameters:Form.serialize(this)}); return false;"> <div style="margin:0;padding:0"> <input name="authenticity_token" type="hidden" value="4eacf78eb87e9262a0b631a8a6e417e9a5957cab" /> </div> <div id="content"> <select id="update" name="update" onchange="this.form.commit.click"> <option value="1">foo</option> <option value="2">bar</option> </select> <input name="commit" style="display: none" type="submit" value="submit_button" /> </div> </form> I want to axe the invisible submit button, but using a straight form.submit appears to not work. So, I need some way to call the form's onsubmit event code. Update: Orion Edwards solution would work if there wasn't a return(false); generated by Rails. I'm not sure which is worse though, sending a phantom click to an invisible submit button or calling eval on the getAttribute('onsubmit') call after removing the return call with a javascript string replacement!

• JQuery get attr value from ajax loaded page

  - by Paolo Rossi

  In my index.php I've a ajax pager that load a content page (paginator.php). index.php <script type='text/javascript' src='js/jquery-1.11.1.min.js'></script> <script type='text/javascript' src='js/paginator.js'></script> <script type='text/javascript' src='js/functions.js'></script> <!-- Add fancyBox --> <script type="text/javascript" src="js/jquery.fancybox.pack.js?v=2.1.5"></script> <html> <div id="content"></div> paginator.js $(function() { var pageurl = 'paginator.php'; //Initialise the table at the first run $( '#content' ).load( pageurl, { pag: 1 }, function() { //animation(); }); //Page navigation click $( document ).on( 'click', 'li.goto', function() { //Get the id of clicked li var pageNum = $( this ).attr( 'id' ); $( '#content' ).load( pageurl, { pag: pageNum }, function() { //animation(); }); }); }); /* END */ paginator.php <ul><li>..etc </ul> ... ... <a id='test' vid='123'>get the id</a> <a id='test2' url='somepage.php'>open fancybox</a> I would like to take a variable of the loaded page (paginator.php) in this way but unfortunately I can not. functions.js $(function() { $('#test' ).click(function(e) { var id = $('#test').attr('vid'); alert ("vid is " + vid); }); }); /* END */ In this case popup not appear. I tried with add fancybox in my functions.js. Dialog box appear but the url attr is not taken. var url = $('#test2').attr('url'); $('#test').fancybox({ 'href' : url, 'width' : 100, 'height' : 100, 'autoScale' : false, 'transitionIn' : 'none', 'transitionOut' : 'none', 'type' : 'iframe', 'fitToView' : true, 'autoSize' : false }); In other scenarios, without having the page loaded, I can do it, but in this case the behavior is different. How could I do this? thanks EDIT my goal is to open a dialog (fancybox) taking a variable from the loaded page EDIT2 I tried in this way paginator.php <a id="test" vid="1234">click me</a> paginator.js //Initialise the table at the first run $( '#content' ).load( pageurl, { pag: 1 }, function() { hide_anim(); popup(); }); //Page navigation click $( document ).on( 'click', 'li.goto', function() { //Get the id of clicked li var pageNum = $( this ).attr( 'id' ); $( '#content' ).load( pageurl, { pag: pageNum }, function() { hide_anim(); popup(); }); }) function.js function popup() { $('#test' ).click(function(e) { e.preventDefault(); var vid = $('#test').attr('vid'); alert ("vid is " + vid); }); } But popup not appear...

• Rogue PropertyChanged notifications from ViewModel

  - by user1886323

  The following simple program is causing me a Databinding headache. I'm new to this which is why I suspect it has a simple answer. Basically, I have two text boxes bound to the same property myString. I have not set up the ViewModel (simply a class with one property, myString) to provide any notifications to the View for when myString is changed, so even although both text boxes operate a two way binding there should be no way that the text boxes update when myString is changed, am I right? Except... In most circumstances this is true - I use the 'change value' button at the bottom of the window to change the value of myString to whatever the user types into the adjacent text box, and the two text boxes at the top, even although they are bound to myString, do not change. Fine. However, if I edit the text in TextBox1, thus changing the value of myString (although only when the text box loses focus due to the default UpdateSourceTrigger property, see reference), TextBox2 should NOT update as it shouldn't receive any updates that myString has changed. However, as soon as TextBox1 loses focus (say click inside TextBox2) TextBox2 is updated with the new value of myString. My best guess so far is that because the TextBoxes are bound to the same property, something to do with TextBox1 updating myString gives TextBox2 a notification that it has changed. Very confusing as I haven't used INotifyPropertyChanged or anything like that. To clarify, I am not asking how to fix this. I know I could just change the binding mode to a oneway option. I am wondering if anyone can come up with an explanation for this strange behaviour? ViewModel: namespace WpfApplication1 { class ViewModel { public ViewModel() { _myString = "initial message"; } private string _myString; public string myString { get { return _myString; } set { if (_myString != value) { _myString = value; } } } } } View: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="MainWindow" Height="350" Width="525"> <Window.DataContext> <local:ViewModel /> </Window.DataContext> <Grid> <!-- The culprit text boxes --> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,70,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,120,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}"/> <!--The buttons allowing manual change of myString--> <Button Name="changevaluebutton" Content="change value" Click="ButtonUpdateArtist_Click" Margin="12,245,416,43" Width="75" /> <Button Content="Show value" Height="23" HorizontalAlignment="Left" Margin="12,216,0,0" Name="showvaluebutton" VerticalAlignment="Top" Width="75" Click="showvaluebutton_Click" /> <Label Content="" Height="23" HorizontalAlignment="Left" Margin="116,216,0,0" Name="showvaluebox" VerticalAlignment="Top" Width="128" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="116,245,0,0" Name="changevaluebox" VerticalAlignment="Top" Width="128" /> <!--simply some text--> <Label Content="TexBox1" Height="23" HorizontalAlignment="Left" Margin="99,70,0,0" Name="label1" VerticalAlignment="Top" Width="61" /> <Label Content="TexBox2" Height="23" HorizontalAlignment="Left" Margin="99,118,0,0" Name="label2" VerticalAlignment="Top" Width="61" /> </Grid> </Window> Code behind for view: namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { ViewModel viewModel; public MainWindow() { InitializeComponent(); viewModel = (ViewModel)this.DataContext; } private void showvaluebutton_Click(object sender, RoutedEventArgs e) { showvaluebox.Content = viewModel.myString; } private void ButtonUpdateArtist_Click(object sender, RoutedEventArgs e) { viewModel.myString = changevaluebox.Text; } } }

• XHTML 1.0 DocType ignored in all browsers?

  I was testing this, since I understood using XHTML let me use any valid XML for empty <div> elements: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <title>Test</title> </head> <body> <div style="border:solid 10px black; width:100px; height:100px"></div> <div style="border:solid 10px red; width:100px; height:100px"></div> <div style="border:solid 10px blue; width:100px; height:100px"></div> <div style="border:solid 10px black; width:100px; height:100px" /> <div style="border:solid 10px red; width:100px; height:100px" /> <div style="border:solid 10px blue; width:100px; height:100px" /> </body> </html> It doesn't work in any browser I try... this is how FireBug tells me it understands the document: <html> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/> <title>Test</title> </head> <body> <div style="border: 10px solid black; width: 100px; height: 100px;"/> <div style="border: 10px solid red; width: 100px; height: 100px;"/> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> <div style="border: 10px solid black; width: 100px; height: 100px;"> <div style="border: 10px solid red; width: 100px; height: 100px;"> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> </div> </div> </body> </html> I'm a bit confused what the point is of using XHTML if I have to do this, I might as well just use HTML? Note, that setting the content type to content="application/xhtml+xml" makes no difference in FF3 at least.

• Jquery only works the first time

  - by Tripping

  I am trying to teach myself general web development skills. I am trying to create a image upload with preview functionality using HTML5 FileAPI. Till now, I have created a file input which shows the preview of image when selected. Html mark up is below: <div> <!-- Photos --> <fieldset> <legend>PropertyPhotos</legend> <div class="upload-box" id="upload-box-1"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_1" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File1) @Html.ValidationMessageFor(model => model.File1) </div> </div> <div class="upload-box" id="upload-box-2"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_2" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File2) @Html.ValidationMessageFor(model => model.File2) </div> </div> <div class="upload-box" id="upload-box-3"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_3" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File3) @Html.ValidationMessageFor(model => model.File3) </div> </div> </fieldset> </div> The Jquery to show preview and then display the next "upload-box" is as follows: <script type="text/javascript"> $(document).ready(function () { // show first box $("#upload-box-1").fadeIn(); //Get current & next step index var stepNum = $('div.upload-box').attr('id').replace(/[^\d]/g, ''); var nextNum = parseInt(stepNum)+1; //Get the preview image tag var preview = $('#preview_'+stepNum); //Load preview on file tag change and display second upload-box $('#File'+stepNum).change(function (evt) { var f = evt.target.files[0]; var reader = new FileReader(); if (!f.type.match('image.*')) { alert("The selected file does not appear to be an image."); return; } reader.onload = function (e) { preview.attr('src', e.target.result); }; reader.readAsDataURL(f); //Show next upload-box $("#upload-box-" + nextNum).fadeIn(); }); }); </script> However, this code only first for the first time ... i.e. on selecting a file - It shows a preview and then shows the next "upload-box". However, when I browse using the second file it doesn't show any preview. From what I have ready, I need to close the Jquery function so that it can be initialised again but I am not sure how to do that. Any help will be grateful.

• linked list problem (with insert)

  - by JohnWong

  The problem appears with the insert function that I wrote. 3 conditions must work, I tested b/w 1 and 2, b/w 2 and 3 and as last element, they worked. But b/w 3 and 4, it did not work. It only display up to the new added record, and did not show the fourth element. Efficiency is not my concern here (not yet). Please guide me through this debug process. Thank you very much. #include<iostream> #include<string> using namespace std; struct List // we create a structure called List { string name; string tele; List *nextAddr; }; void populate(List *); void display(List *); void insert(List *); int main() { const int MAXINPUT = 3; char ans; List * data, * current, * point; // create two pointers data = new List; current = data; for (int i = 0; i < (MAXINPUT - 1); i++) { populate(current); current->nextAddr = new List; current = current->nextAddr; } // last record we want to do it sepeartely populate(current); current->nextAddr = NULL; cout << "The current list consists of the following data records: " << endl; display(data); // now ask whether user wants to insert new record or not cout << "Do you want to add a new record (Y/N)?"; cin >> ans; if (ans == 'Y' || ans == 'y') { /* To insert b/w first and second, use point as parameter between second and third uses point->nextAddr between third and fourth uses point->nextAddr->nextAddr and insert as last element, uses current instead */ point = data; insert(()); display(data); } return 0; } void populate(List *data) { cout << "Enter a name: "; cin >> data->name; cout << "Enter a phone number: "; cin >> data->tele; return; } void display(List *content) { while (content != NULL) { cout << content->name << " " << content->tele; content = content->nextAddr; cout << endl; // we skip to next line } return; } void insert(List *last) { List * temp = last->nextAddr; //save the next address to temp last->nextAddr = new List; // now modify the address pointed to new allocation last = last->nextAddr; populate(last); last->nextAddr = temp; // now link all three together, eg 1-NEW-2 return; }

• Problems with this code?

  - by J4C3N-14

  I'm trying to use this code which is an example taken from here https://gist.github.com/2383248 , but it is coming up with a error on the public void onClick which is Multiple markers at this line - implements android.view.View.OnClickListener.onClick - Syntax error, insert "}" to complete MethodBody, but when I add the brace it just throws another error after many tries and fails of different suggestions and ideas. It may be a syntax error and bad coding from me (just started learning to program) but does anyone have any ideas how to resolve this or point me in the right direction I would be very grateful. public class ICSCalendarActivity extends Activity implements View.OnClickListener{ Button button1; int year1; int month1; int day1; int ShiftPattern; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button1 = (Button)findViewById(R.id.openButton); button1.setText("open"); button1.setOnClickListener(this); Bundle extras = getIntent().getExtras(); year1 = extras.getInt("year1"); day1 = extras.getInt("day1"); month1 = extras.getInt("month1"); ShiftPattern = extras.getInt("ShiftPattern"); } public void onClick(View v){ private static void addToCalendar(Context ICSCalendarActivity, final String title, final long dtstart, final long dtend) { final ContentResolver cr = ICSCalendarActivity.getContentResolver(); Cursor cursor ; if (Integer.parseInt(Build.VERSION.SDK) >= 8 ) cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null); else cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null); if ( cursor.moveToFirst() ) { final String[] calNames = new String[cursor.getCount()]; final int[] calIds = new int[cursor.getCount()]; for (int i = 0; i < calNames.length; i++) { calIds[i] = cursor.getInt(0); calNames[i] = cursor.getString(1); cursor.moveToNext(); } AlertDialog.Builder builder = new AlertDialog.Builder(ICSCalendarActivity); builder.setSingleChoiceItems(calNames, -1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { ContentValues cv = new ContentValues(); cv.put("calendar_id", calIds[which]); cv.put("title", title); cv.put("dtstart", dtstart ); cv.put("hasAlarm", 1); cv.put("dtend", dtend); Uri newEvent ; if (Integer.parseInt(Build.VERSION.SDK) >= 8 ) newEvent = cr.insert(Uri.parse("content://com.android.calendar/events"), cv); else newEvent = cr.insert(Uri.parse("content://calendar/events"), cv); if (newEvent != null) { long id = Long.parseLong( newEvent.getLastPathSegment() ); ContentValues values = new ContentValues(); values.put( "event_id", id ); values.put( "method", 1 ); values.put( "minutes", 15 ); // 15 minutes if (Integer.parseInt(Build.VERSION.SDK) >= 8 ) cr.insert( Uri.parse( "content://com.android.calendar/reminders" ), values ); else cr.insert( Uri.parse( "content://calendar/reminders" ), values ); } dialog.cancel(); } }); builder.create().show(); } cursor.close(); } } Thank you.

• 501 Error during Libjingle PCP on Amazone EC2 running Openfire

  - by AeroBuffalo

  I am trying to implement Google's Libjingle (version: 0.6.14) PCP example and I am getting a 501: feature not implemented error during execution. Specifically, the error occurs after each "account" has connected, been authenticated and began communicating with the other. An abbreviated log of the interaction is provided at the end. I have set up my own jabber server (using OpenFire on an Amazon EC2 server), have opened all of the necessary ports and have added each "account" to the other's roster. The server has been set to allow for file transfers. My being new to working with servers, I am not sure why this error is occur and how to go about fixing it. Thanks in advance, AeroBuffalo P.S. Let me know if there is any additional information needed (i.e. the full program log for either/both ends).

• Python soap using soaplib (server) and suds (client)

  - by Celso Axelrud

  This question is related to: http://stackoverflow.com/questions/1751027/python-soap-server-client In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client. My target is to create soap services in python that can be consumed by several clients (java, etc). I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). It works well when the client is also using soaplib. Then, I tried to use suds as client consuming the HelloWorld services and it fail. -Why this is happening? Does soaplib server has problems to consumed by different clients? Here the code for the server: from soaplib.wsgi_soap import SimpleWSGISoapApp from soaplib.service import soapmethod from soaplib.serializers.primitive import String, Integer, Arraycode class HelloWorldService(SimpleWSGISoapApp): @soapmethod(String,Integer,_returns=Array(String)) def say_hello(self,name,times): results = [] for i in range(0,times): results.append('Hello, %s'%name) return results if __name__=='__main__': from cherrypy.wsgiserver import CherryPyWSGIServer #from cherrypy._cpwsgiserver import CherryPyWSGIServer # this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0 server = CherryPyWSGIServer(('localhost',7789),HelloWorldService()) server.start() This is the soaplib client: from soaplib.client import make_service_client from SoapServerTest_1 import HelloWorldService client = make_service_client('http://localhost:7789/',HelloWorldService()) print client.say_hello("Dave",5) Results: >>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave'] This is the suds client: from suds.client import Client url = 'http://localhost:7789/HelloWordService?wsdl' client1 = Client(url) client1.service.say_hello("Dave",5) Results: >>> Unhandled exception while debugging...

• jQuery doesn't work in IE8?

  - by Wade D Ouellet

  Hi, I am working on a site here: mfm.treethink.net All the jquery works fine in Firefox, Chrome and Safari but on IE8 it gives me errors and the banner at the top doesn't work (which uses the crossSlide jQuery plugin) and as well the image rollovers don't work with the colour change. IE8 is telling me that the errors are on lines 53, 134 and 149 in the source, all of those lines are where the jquery function is declared. $(document).ready(function(){ I am running jquery 1.4. Oddly enough, the other piece of jQuery I have on that page works, the artist browse/select menu on the right. But the banner and image rollovers don't. Here are all the scripts I'm running: 1: the banner - doesn't work in IE8 <script type="text/javascript"> $(function() { $('#banner').crossSlide({ sleep: 5, fade: 1 }, [ <?php $pages = get_posts('numberposts=2000&post_type=artist&post_status=publish'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> { src: '/wp-content/uploads/<?php echo $page->post_name ?>.jpg' }, <?php $i++; } ?> ]); }); </script> 2 - image rollovers - doesn't work in IE8 <script type="text/javascript"> $(function(){ $("ul#artists li").hover(function() { /* On hover */ var thumbOver = $(this).find("img").attr("src"); /* Find image source */ /* Swap background */ $(this).find("a.thumb").css({'background' : 'url(' + thumbOver + ') center bottom no-repeat'}); $(this).find("span").stop().fadeTo('fast', 0 , function() { $(this).hide() }); } , function() { $(this).find("span").stop().fadeTo('fast', 1).show(); }); }); </script> 3 - the artist select - works in IE 8 <script> $("#browse-select").change(function() { window.location.href = $(this).val(); }); </script> These scripts were done by referencing previously made scripts, like I said I'm still new to jQuery. The second works in IE8 and the first one is the one that doesn't. I noticed the third one, the only one working, is written differently than the first two non-working ones without a function declaration at the top. Could this have anything to do with it? Any help figuring out this problem would be so appreciated. Thanks a lot, Wade

• Custom DataAnnotation attribute with datastore access in ASP.NET MVC 2

  - by mare

  I have my application designed with Repository pattern implemented and my code prepared for optional dependency injection in future, if we need to support another datastore. I want to create a custom validation attribute for my content objects. This attribute should perform some kind of datastore lookup. For instance, I need my content to have unique slugs. To check if a Slug already exist, I want to use custom DataAnnotation attribute in my Base content object (instead of manually checking if a slug exists each time in my controller's Insert actions). Attribute logic would do the validation. So far I have come up with this: public class UniqueSlugAttribute : ValidationAttribute { private readonly IContentRepository _repository; public UniqueSlugAttribute(ContentType contentType) { _repository = new XmlContentRepository(contentType); } public override bool IsValid(object value) { if (string.IsNullOrWhiteSpace(value.ToString())) { return false; } string slug = value.ToString(); if(_repository.IsUniqueSlug(slug)) return true; return false; } } part of my Base content class: ... [DataMember] public ContentType ContentType1 { get; set; } [DataMember] [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = "Validation_SlugIsBlank")] [UniqueSlug(ContentType1)] public string Slug { get { return _slug; } set { if (!string.IsNullOrEmpty(value)) _slug = Utility.RemoveIllegalCharacters(value); } } ... There's an error in line [UniqueSlug(ContentType1)] saying: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type." Let me explain that I need to provide the ContentType1 parameter to the Constructor of UniqueSlug class because I use it in my data provider. It is actually the same error that appears if you try do to this on the built-in Required attribute: [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = Resources.Localize.SlugRequired] It does not allow us to set it to dynamic content. In the first case ContentType1 gets known at runtime, in the second case the Resources.Localize.SlugRequired also gets known at runtime (because the Culture settings are assigned at runtime). This is really annoying and makes so many things and implementation scenarios impossible. So, my first question is, how to get rid of this error? The second question I have, is whether you think that I should redesign my validation code in any way?

• Binding a wpf listbox to a combobox

  - by user293545

  Hi there, I have created a very basic wpf application that I want to use to record time entries against different projects. I havent used mvvm for this as I think its an overkill. I have a form that contains a combobox and a listbox. I have created a basic entity model like this What I am trying to do is bind the combobox to Project and whenever I select an item from the combobox it updates the listview with the available tasks associated with that project. This is my xaml so far. I dont have any code behind as I have simply clicked on that Data menu and then datasources and dragged and dropped the items over. The application loads ok and the combobox is been populated however nothing is displaying in the listbox. Can anyone tell me what I have missed? <Window.Resources> <CollectionViewSource x:Key="tasksViewSource" d:DesignSource="{d:DesignInstance l:Task, CreateList=True}" /> <CollectionViewSource x:Key="projectsViewSource" d:DesignSource="{d:DesignInstance l:Project, CreateList=True}" /> </Window.Resources> <Grid DataContext="{StaticResource tasksViewSource}"> <l:NotificationAreaIcon Text="Time Management" Icon="Resources\NotificationAreaIcon.ico" MouseDoubleClick="OnNotificationAreaIconDoubleClick"> <l:NotificationAreaIcon.MenuItems> <forms:MenuItem Text="Open" Click="OnMenuItemOpenClick" DefaultItem="True" /> <forms:MenuItem Text="-" /> <forms:MenuItem Text="Exit" Click="OnMenuItemExitClick" /> </l:NotificationAreaIcon.MenuItems> </l:NotificationAreaIcon> <Button Content="Insert" Height="23" HorizontalAlignment="Left" Margin="150,223,0,0" Name="btnInsert" VerticalAlignment="Top" Width="46" Click="btnInsert_Click" /> <ComboBox Height="23" HorizontalAlignment="Left" Margin="70,16,0,0" Name="comProjects" VerticalAlignment="Top" Width="177" DisplayMemberPath="Project1" ItemsSource="{Binding Source={StaticResource projectsViewSource}}" SelectedValuePath="ProjectID" /> <Label Content="Projects" Height="28" HorizontalAlignment="Left" Margin="12,12,0,0" Name="label1" VerticalAlignment="Top" IsEnabled="False" /> <Label Content="Tasks" Height="28" HorizontalAlignment="Left" Margin="16,61,0,0" Name="label2" VerticalAlignment="Top" /> <ListBox Height="112" HorizontalAlignment="Left" Margin="16,87,0,0" Name="lstTasks" VerticalAlignment="Top" Width="231" DisplayMemberPath="Task1" ItemsSource="{Binding Path=ProjectID, Source=comProjects}" SelectedValuePath="TaskID" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="101,224,0,0" Name="txtMinutes" VerticalAlignment="Top" Width="42" /> <Label Content="Mins to Insert" Height="28" HorizontalAlignment="Left" Margin="12,224,0,0" Name="label3" VerticalAlignment="Top" /> <Button Content="None" Height="23" HorizontalAlignment="Left" Margin="203,223,0,0" Name="btnNone" VerticalAlignment="Top" Width="44" /> </Grid>

• firefox, jQuery ajax calls firing twice and never triggering success or error functions

  - by Adrian Adkison

  Hi, I am developing with the .NET framework, using jQuery 1.4.2 client side. When developing in Firefox version 3.6, every so often an one of the many ajax calls I make on the page will fire twice, the second will return successfully but will not trigger the success handler of the ajax call and the first never returns anything. So basically the data is all sent to the server and response is sent down but nothing happens with the response. Here is an example of the call I am making. It happens to any of the ajax calls, so there is not one particular that is causing the problem: $.ajax({ type:"POST", contentType : "application/json; charset=utf-8", data:"{}", dataType:"json", success:function(){ alert('success'); }, error:function(){ alert('error'); }, url:'/services.aspx/somemethod' }); }) From firebug, here are the headers of the first call which in firebug shows as never completely responding, meaning i see no response code and the loader gif in the firebug never goes away. Note:In firebug it usually says Response Header but for the first call this space is blank Server ASP.NET Development Server/9.0.0.0 X-AspNet-Version 2.0.50727 Content-Type application/json; charset=utf-8 Connection Close Request Headers Host mydomain.com User-Agent Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401Firefox/3.6.3 ( .NET CLR 3.5.30729) Accept application/json, text/javascript, */* Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Content-Type application/json; charset=utf-8 X-Requested-With XMLHttpRequest Referer http://mydomain.com/mypage.aspx Here is the header from the second request which just appear to complete in firebug (i.e response is 200): Response Header Server ASP.NET Development Server/9.0.0.0 X-AspNet-Version 2.0.50727 Content-Type application/json; charset=utf-8 Connection Close Request Headers Host mydomain.com User-Agent Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 ( .NET CLR 3.5.30729) Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Content-Type application/json; charset=utf-8 Referer http://mydomain.com/mypage.aspx To summarize my question, why are two requests being made and why are neither of them triggering a success or error handler in the ajax call. I have seen this article about firefox 3.5+ and preflighted requests https://developer.mozilla.org/En/HTTP_access_control#Preflighted_requests In the article is says if a "POST" is made with any other content type than "application/x-www-form-urlencoded, multipart/form-data, or text/plain" than the request is pre-flighted. If this is the case, this should happen to all of my calls. Thanks

• .exe File becomes corrupted when downloaded from server

  - by Kerri

  Firstly: I'm a lowly web designer who knows just enough PHP to be dangerous and just enough about server administration to be, well, nothing. I probably won't understand you unless you're very clear! The setup: I've set up a website where the client uploads files to a specific directory, and those files are made available, through php, for download by users. The files are generally executable files over 50MB. The client does not want them zipped, as they feel their users aren't savvy enough to unzip them. I'm using the php below to force a download dialogue box and hide the directory where the files are located. It's Linux server, if that makes a difference. The problem: There is a certain file that becomes corrupt after the user tries to download it. It is an executable file, but when it's clicked on, a blank DOS window opens up. The original file, prior to download opens perfectly. There are several other similar files that go through the same exact download procedure, and all of those work just fine. Things I've tried: I've tried uploading the file zipped, then unzipping it on the server to make sure it wasn't becoming corrupt during upload, and no luck. I've also compared the binary code of the original file to the downloaded file that doesn't work, and their exactly the same (so the php isn't accidentally inserting anything extra into the file). Could it be an issue with the headers in my downloadFile function? I really am not sure how to troubleshoot this one… This is the download php, if it's relevant ($filenamereplace is defined elsewhere): downloadFile("../DOWNLOADS/files/$filenamereplace","$filenamereplace"); function downloadFile($file,$filename){ if(file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename="'.$filename.'"'); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); @ flush(); readfile($file); exit; } }

• Problem with displaying and downloading email attachments using the zend framework

  - by Ali

  Hi guys I'm trying to display emails in my inbox and their respective attachments. At the same time I also wish to be able to download the attachments however I'm kinda stuck here. Here is the code I use to display the attachments: $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); // get the contact of this message $email = array_pop(extract_emails_from($one_message->from)); $one_message->contactFrom = $contact_manager->get_person_from_email($email); $one_message->parts = array(); foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; $one_message->parts[$ii] = $tpart; // put the part of the message indexed with what I assume is its position if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); $h2t->set_html($b); $one_message->body = $h2t->get_text(); } if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); $one_message->body = $part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } And I display the attachments using the following link: ?action=download&element=email-attachment&box=inbox&uid=<?php echo $one_message->UID;?>&id=<?php echo $one_message->id;?>&part=<?php echo $ii;?> The part variable is the index taken from the loop above However when I try to download using the exact same code as above modified slightly: $id = $_GET['id']; $pid = $_GET['part']; $one_message = $mail->getMessage($id); foreach (new RecursiveIteratorIterator($mail->getMessage($id)) as $ii=>$part) { if($pid == $ii): $content = base64_decode($part->getContent()); $cnt_typ = explode(";" , $part->contentType); $name = explode("=",$cnt_typ[1]); $filename = $name[1];//It is the file name of the attachement in browser //This for avoiding " from the file name when sent from yahoomail $filename = str_replace('"'," ",$filename); $filename = trim($filename); header("Cache-Control: public"); header("Content-Type: ".$cn_typ[1]); header("Content-Disposition: attachment; filename=\"" . $filename . "\""); header("Content-Transfer-Encoding: binary"); echo $content; exit; endif; } For some reason it doesn't work at all. I did a var dump and noticed that in the for loop with the reverseiterator teh indexes $ii returned are 1 - 2 - 2 !! Whats going on here how can the indexes be repeated? How can I tell one part from the others?

• How Do I Prevent Rails From Treating Updated Nested Attributes Differently From New Nested Attribute

  - by James

  I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

• NSCollectionView draws nothing

  - by PCWiz

  I'm trying to set up an NSCollectionView (I have done this successfully in the past, but for some reason it fails this time). I have a model class called "TestModel", and it has an NSString property that just returns a string (just for testing purposes right now). I then have an NSMutableArray property declaration in my main app delegate class, and to this array I add instances of the TestModel object. I then have an Array Controller that has its Content Array bound the app delegate's NSMutableArray. I can confirm that everything up to here is working fine; NSLogging: [[[arrayController arrangedObjects] objectAtIndex:0] teststring] worked fine. I then have all the appropriate bindings for the collection view set up, (itemPrototype and content), and for the Collection View Item (view). I then have a text field in the collection item view that is bound to Collection View Item.representedObject.teststring. However NOTHING displays in the collection view when I start the app, just a blank white screen. What am I missing? UPDATE: Here is the code I use (requested by wil shipley): // App delegate class @interface AppController : NSObject { NSMutableArray *objectArray; } @property (readwrite, retain) NSMutableArray *objectArray; @end @implementation AppController @synthesize objectArray; - (id)init { if (self = [super init]) { objectArray = [[NSMutableArray alloc] init]; } return self; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { TestModel *test = [[[TestModel alloc] initWithString:@"somerandomstring"] autorelease]; if (test) [objectArray addObject:test]; } @end // The model class (TestModel) @interface TestModel : NSObject { NSString *teststring; } @property (readwrite, retain) NSString *teststring; - (id)initWithString:(NSString*)customString; @end @implementation TestModel @synthesize teststring; - (id)initWithString:(NSString*)customString { [self setTeststring:customString]; } - (void)dealloc { [teststring release]; } @end And then like I said the content array of the Array Controller is bound to this "objectArray", and the Content of the NSCollectionView is bound to Array Controller.arrangedObjects. I can verify that the Array Controller has the objects in it by NSLogging [arrayController arrangedObjects], and it returns the correct object. Its just that nothing displays in the NSCollectionView. UPDATE 2: If I log [collectionView content] I get nothing: 2009-10-21 08:02:42.385 CollViewTest[743:a0f] ( ) The problem is probably there. UPDATE 3: As requested here is the Xcode project: http://www.mediafire.com/?mjgdzgjjfzw Its a menubar app, so it has no window. When you build and run the app you'll see a menubar item that says "test", this opens the view that contains the NSCollectionView. Thanks

• Problems with CGI wrapper for PHP

  - by user205878

  I'm having a bugger of a time with a CGI wrapper for PHP. I know very little about CGI and PHP as CGI. Here's what I know about the system: Solaris 10 on a 386 Suhosin PHP normally running as CGI, with cgiwrap (http://cgiwrap.sourceforge.net/). I am not able to find an example wrapper.cgi on the server to look at. Shared hosting (virtual host), so I don't have access to Apache config. But the admins are not helpful. Switching hosts is not an option. Options directive cannot be overridden in .htaccess (ExecCGI, for example). .htaccess: AddHandler php-handler .php Action php-handler "/bin/test.cgi" ~/public_html/bin/test.cgi: #!/usr/bin/sh # Without these 2 lines, I get an Internal Server Error echo "Content-type: text/html" echo "" exec "/path/to/php-cgi" 'foo.php'; /bin/foo.php: <?php echo "this is foo.php!"; Output of http://mysite.com/bin/test.cgi: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; Output of http:/ /mysite.com/anypage.php: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; The things I note are: PHP is being executed, as noted by the X-Powered-By ... header. The source of /bin/test.cgi is output in the results. No matter what I put as the second argument of exec, it isn't passed to the php binary. I've tried '-i' to get phpinfo, '-v' to get the version... When I execute test.cgi via the shell, I get the expected results (the argument is passed to php, and it is reflected in the output). Any ideas about how to get this to work? UPDATE It appears that the reason the source of the test.cgi was appearing was due to errors. Anytime fatal error occurred, either within the cgi itself or with the command being executed by exec, it would cause the source of the cgi to appear. Within test.cgi, I can get the proper output with exec "/path/to/php-cgi" -h (I get the same thing as I would from CLI).

• Can MFMailComposeViewController attach an XML doc to an HTML message?

  - by Luther Baker

  I am creating an email in MFMaiilComposeViewController and if I simply create some html snippets and assign them to the message body - all is well. The resulting email (in GMail and Yahoo) looks like the original HTML I sent. [mailMan_ setMessageBody:body isHTML:YES]; On the other hand, if I also include an XML attachment, my email reader renders everything as plain text … including, the XML inlined. IE: my mail client (GMail, Yahoo) shows the raw HTHML and XML tags - including html tags that I didn't supply - ie: the html, head, body tags the iPhone provides around the content: NSData *opmlData = [[NSData alloc] initWithData:[opml dataUsingEncoding:NSUTF8StringEncoding]]; NSString *fileName = [NSString stringWithFormat:@"%f.opml", [NSDate timeIntervalSinceReferenceDate]]; [mailMan_ addAttachmentData:opmlData mimeType:@"text/xml" fileName:fileName]; I pop3'd the mails to see what was happening and found that WITHOUT an attachment, the resulting html section of the email contains this block: --0-1682099714-1273329398=:59784 Content-Type: text/html; charset=us-ascii <html><body bgcolor="#FFFFFF"><div><h2 style="b while on the other hand, WITH the XML attachment, the iPhone is sending this: --0-881105825-1273328091=:50337 Content-Type: text/plain; charset=us-ascii <html><body bgcolor="#FFFFFF"><div><h2 style="bac Notice the difference? Look at the Content-Type … text/html vs text/plain. It looks like when I include an XML attachment, the iPhone is errantly tagging the HTML version of the body as plain text! Just to clarify, technically, both with and without the attachment, the iPhone also includes this: --0-881105825-1273328091=:50337 Content-Type: text/plain; charset=us-ascii Notebook Carpentry Bathroom floor tile Bathroom wall tile Scrape thinset But this obviously isn't where the problem lies. Am I doing something wrong? What must I do to actually "attach" XML without the iPhone labeling the entire HTML body as plain text. I tried reversing the assignments (attachment first and then body) but no luck. For what it's worth, the email looks perfect from the iPhone's sending interface. Indeed, the HTML renders correctly and the attachment looks like a little icon at the bottom of the message. This problem has more to do with what the iPhone is actually sending.

• Binding Silverlight UserControl custom properties to its' elements

  - by ghostskunks

  Hi. I'm trying to make a simple crossword puzzle game in Silverlight 2.0. I'm working on a UserControl-ish component that represents a square in the puzzle. I'm having trouble with binding up my UserControl's properties with its' elements. I've finally (sort of) got it working (may be helpful to some - it took me a few long hours), but wanted to make it more 'elegant'. I've imagined it should have a compartment for the content and a label (in the upper right corner) that optionally contains its' number. The content control probably be a TextBox, while label control could be a TextBlock. So I created a UserControl with this basic structure (the values are hardcoded at this stage): <UserControl x:Class="XWord.Square" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" FontSize="30" Width="100" Height="100"> <Grid x:Name="LayoutRoot" Background="White"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <TextBlock x:Name="Label" Grid.Row="0" Grid.Column="1" Text="7"/> <TextBox x:Name="Content" Grid.Row="1" Grid.Column="0" Text="A" BorderThickness="0" /> </Grid> </UserControl> I've also created DependencyProperties in the Square class like this: public static readonly DependencyProperty LabelTextProperty; public static readonly DependencyProperty ContentCharacterProperty; // ...(static constructor with property registration, .NET properties // omitted for brevity)... Now I'd like to figure out how to bind the Label and Content element to the two properties. I do it like this (in the code-behind file): Label.SetBinding( TextBlock.TextProperty, new Binding { Source = this, Path = new PropertyPath( "LabelText" ), Mode = BindingMode.OneWay } ); Content.SetBinding( TextBox.TextProperty, new Binding { Source = this, Path = new PropertyPath( "ContentCharacter" ), Mode = BindingMode.TwoWay } ); That would be more elegant done in XAML. Does anyone know how that's done?

• Blackberry Player, custom data source

  Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem.
