  • Use shared 404 page for virtual hosts in Nginx

    - by Choy
    I'd like to have a shared 404 page to use across my virtual hosts. The following is my setup. Two sites, each with their own config file in /sites-available/ and /sites-enabled/ www.foo.com bar.foo.com The www directory is set up as: www/ foo.com/ foo.com/index.html bar.foo.com/ bar.foo.com/index.html shared/ shared/404.html Both config files in /sites-available are the same except for the root and server name: root /var/www/bar.foo.com; index index.html index.htm index.php; server_name bar.foo.com; location / { try_files $uri $uri/ /index.php; } error_page 404 /404.html; location = /404.html { root /var/www/shared; } I've tried the above code and also tried setting error_page 404 /var/www/shared/404.html (without the following location block). I've also double checked to make sure my permissions are set to 775 for all folders and files in www. When I try to access a non-existent page, Nginx serves the respective index.php of the virtual host I'm trying to access. Can anyone point out what I'm doing wrong? Thanks!

  • getting all contacts (including from other syncAdapters) in android content handler.

    - by eyal
    Hi i have this Query: private Cursor getContacts(CharSequence constraint) { boolean hasConstrains = constraint != null && constraint.length() != 0; Uri uri = ContactsContract.Contacts.CONTENT_URI; String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; String selection = hasConstrains ? projection[1] + " LIKE '"+constraint+"%'" : null; String[] selectionArgs = null; String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " ASC"; return managedQuery(uri, projection, selection, selectionArgs, sortOrder); } The first time issue it i give null as parameter to the function to the selection parameter is empty, meaning i don't filter any rows. The problem is i get only contacts i created myself using no syncAdapter. I used facebook app to synch my facebook contacts, but this query doesn't return them. I extracted the contacts2.db from the emulator and the view_contacts view shows me all the contacts, so the DB is updated. What should i do to get all the contacts regardless of how they were created (with which synch adapter)

  • Django - Override admin site's login form

    - by TrojanCentaur
    I'm currently trying to override the default form used in Django 1.4 when logging in to the admin site (my site uses an additional 'token' field required for users who opt in to Two Factor Authentication, and is mandatory for site staff). Django's default form does not support what I need. Currently, I've got a file in my templates/ directory called templates/admin/login.html, which seems to be correctly overriding the template used with the one I use throughout the rest of my site. The contents of the file are simply as below: # admin/login.html: {% extends "login.html" %} The actual login form is as below: # login.html: {% load url from future %}<!DOCTYPE html> <html> <head> <title>Please log in</title> </head> <body> <div id="loginform"> <form method="post" action="{% url 'id.views.auth' %}"> {% csrf_token %} <input type="hidden" name="next" value="{{ next }}" /> {{ form.username.label_tag }}<br/> {{ form.username }}<br/> {{ form.password.label_tag }}<br/> {{ form.password }}<br/> {{ form.token.label_tag }}<br/> {{ form.token }}<br/> <input type="submit" value="Log In" /> </form> </div> </body> </html> My issue is that the form provided works perfectly fine when accessed using my normal login URLs because I supply my own AuthenticationForm as the form to display, but through the Django Admin login route, Django likes to supply it's own form to this template and thus only the username and password fields render. Is there any way I can make this work, or is this something I am just better off 'hard coding' the HTML fields into the form for?

  • Retrieving many huge sized EPS files and converting them to JPEG in ASP.NET application

    - by Ashish Gupta
    I have many (600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents). So I have two issues:- 1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):- Approach 1:- foreach(var DataRow in DataTable.Rows) { // get the Id and byte[] of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or foreach(var DataRow in DataTable.Rows) { // get only the Id of EPS // Hit database to get the content of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or Any other approach? 2) Converting EPS to JPEG using a web method for 600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this? Also, is doing the entire thing in a SQL CLR function a good idea?

  • Including variables inside curly braces in a Zend config ini file on Linux

    - by Dave Morris
    I am trying to include a variable in a .ini file setting by surrounding it with curly braces, and Zend is complaining that it cannot parse it properly on Linux. It works properly on Windows, though: welcome_message = Welcome, {0}. This is the error that is being thrown on Linux: : Uncaught exception 'Zend_Config_Exception' with message 'Error parsing /var/www/html/portal/application/configs/language/messages.ini on line 10 ' in /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php:181 Stack trace: 0 /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php(201): Zend_Config_Ini-&gt;_parseIniFile('/var/www/html/p...') 1 /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php(125): Zend_Config_Ini-&gt;_loadIniFile('/var/www/html/p...') 2 /var/www/html/portal/library/Ingrain/Language/Base.php(49): Zend_Config_Ini-&gt;__construct('/var/www/html/p...', NULL) 3 /var/www/html/portal/library/Ingrain/Language/Base.php(23): Ingrain_Language_Base-&gt;setConfig('messages.ini', NULL, NULL) 4 /var/www/html/portal/library/Ingrain/Language/Messages.php(7): Ingrain_Language_Base-&gt;__construct('messages.ini', NULL, NULL, NULL) 5 /var/www/html/portal/library/Ingrain/Helper/Language.php(38): Ingrain_Language_Messages-&gt;__construct() 6 /usr/local/zend/share/ZendFramework/library/Zend/Contr in We are able to get the error to go away on Linux if we surround the braces with quotes, but that seems like a strange solution: welcome_message = Welcome, "{"0"}".

  • There is no attachment in the sent mail by iPhone

    - by naruhodo
    I'm trying to send a recorded sound file as attachment with MFMailComposeViewController. The sound file is OK. The picker shows the correct file name, shows the audio file icon as attachment, sends the mail, but there is no attachment in the result. I attached below the source of the sent mail. There is a "text/plain" content type part instead of "Content-Disposition: attachment;" as expected. This is my code code to define the path and attach the audio file. What could be wrong? #define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] #define FILEPATH [DOCUMENTS_FOLDER stringByAppendingPathComponent:[self dateString]] ... NSURL *url = [NSURL fileURLWithPath:FILEPATH]; self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; ...

  • Export SWC from Flash and Access Child from Flex

    - by php html
    I'm creating an actionscript project in Flex Builder. I succeed to export from Flash a SWC file, and to use it succesfully in Flex. I have a good programming background and Flex looks very simple for me, but I have difficult times in flash. I'm trying to achieve something that might be very simple(not for me of course): I create a simple shape in Flash, convert it to symbol. Then I create a TextField. The I select both the elements and convert them to another symbol, and Export it as a movieclip in swc. In flex I want to change the value from the textfield. How should I do? I'm trying to do: var t:ExportedMC = new ExportedMC(); t....(what should I write here) As I mentioned when I open flash I feel like an elephant in a porcelain store. I have 2 questions here: - how to assign a name to the textfield in flash? I'm using CS4. - how to access it as a child in flex?

  • Javascript won't execute in iPhone Safari

    - by Stuart Meyer
    I'm running into this issue only because I recently purchased an iPhone. The javascript for a picture carousel on my website (http://www.stuartmeyerphotography.com) won't execute in Safari for iPhone. I thought it worked on Mac Safari last I checked with a friend who had a Mac (a year ago), but now I need to go back and check that too to make sure it works on the Mac. "View source" on my website would show the entire html page, but I've pulled the code from the body section to show here: carousel({id:'Photos', border:'', size_mode:'image', width:120, height:120, sides:8, steps:75, speed:4, direction:'left', images:['mainthumbs/babiesthumb.jpg','mainthumbs/engagementsthumb.jpg','mainthumbs/dancethumb1.jpg','mainthumbs/artistthumb.jpg','mainthumbs/portraitsthumb1.jpg','mainthumbs/seniorsthumb1.jpg','mainthumbs/wedthumb1.jpg'], links:['babies/babies.html','engagements/engagemainshow/engagementpictures.html','dance/dancepictures.html','artists/artists.html','portraits/portraits.html','seniors/highschoolseniors.html','weddings/weddings.html'], lnk_base:'', lnk_targets:['_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1' ], lnk_attr:['width=200,height=300,top=200,menubar=yes', 'width=300,height=200,left=400,scrollbars=yes', 'width=150,height=250,left=200,top=100', ''], titles:['Babies', 'Engagements', 'Dance', 'Artists', 'Portraits', 'HS Seniors', 'Weddings'], image_border_width:1, image_border_color:'#E3F0A1' });   </div> Any thoughts? -Stuart

  • Overridden button control escaping content. How to stop it?

    - by RemotecUk
    Hi, I've got an ASP.Net button control that I have overridden to provide different functionality. the code looks as follows.. I'm overriding the Render method to surround the control with an <a>... /// <summary> /// Render Method /// </summary> /// <param name="writer"></param> protected override void Render(HtmlTextWriter writer) { base.CssClass = "euva-button-decorated"; writer.Write("<a class=\"euva-button\">"); base.Render(writer); writer.Write("</a>"); } When I check the generated source on the page, I find that where ASP.Net has injected its click handler it does the following... <a class="euva-button"><input type="submit" name="TestButton" value="Test Button" onclick="clickOnce(this);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;TestButton&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" id="TestButton" class="euva-button-decorated" /></a> ... it seems to be escaping the output for the double quotes which means that the browser cannot understand the javascript. How do I make the render method not escape the injected ASP.Net client click handler ?? Note I also have my own client click handler which is declared declaratively in the page mark-up.

  • Recommendation needed for text content, should I use text files or database?

    - by Jörgen
    I'm doing a web application in asp.net mvc. Now I'm at the point where I do alot of text info such as help texts, eula, privacy policy etc. I realized that I'm not sure what would the best way to store these texts. 1. Directly in the aspx page 2. In text files and then load the text via ViewData[] to the aspx file 3. In my sql database If use option 3 how would I then design the database e.g. eula = table x, privacypolicy=table y? I guess I just need some directions of what't the pros and cons with the options above.

  • Getting content from PHP: Trouble with POST and query.

    - by vgm64
    Apologies for my longest question on SO ever. I'm trying to interface with a php frontend for a mysql database in ROOT (a CERN framework in C++ for high energy physics analysis). To start off with, I tried to get this php interface to play nice with wget and curl first because I'm more familiar with them. The following command works: wget --post-data "hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases;" http://some.host.edu/log/log_query_matlab.php The results are: database1 database2 That's good. If I leave out the --post-data then I get the result: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 6 i'm dead! Access denied for user 'admin'@'localhost' (using password: NO) Warning: mysql_query() [function.mysql-query]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 29 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /log/log_query_matlab.php on line 29 I have access to the php script (read only), but the error itself isn't too important. What matters it that using ROOT, I use a function called as socket.SendRaw(message, message.Length()) (socket is a TSocket) and this gives me the same "error" as wget without the post data switch if my "message" is "POST http://some.host.edu/log/log_query_matlab.php?hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases" This may be in vain, but does someone knows a way I should format the "message" that includes something that is equivalent to the --post-data switch. Or, is there a standard way to format POST requests in a single line (I've seen multi-line stuff. Is that right?) Sorry I'm clueless! PS. The mysql query is show databases but the space has been replaced with _spazio_, Italian for space. The author of the db and php interface requires it (and various replacements for symbols), but has anyone seen this before? Trying to troubleshoot that was terrible!

  • using the window object for accessing global user defined objects and using text within html for cre

    - by timpone
    I don't do very much jquery / javascript but wanted to ask for some advice on the following piece. I have tried to cut out as much as possible. Most of this was semi-inherited code with catching a bunch of events just hardcoded in. I'd like to generalized them more by putting the object name in the html and accessing via jquery on processing (by_date, by_popularity). I retriev as string and access the object via window[current_obj]. Is this a good way to do this or am I missing something? Are there preferable ways to introduce specificity. thanks for any advice. <script> var by_date={}; by_date.current_page=1; by_date.per_page=4; var by_popularity={}; by_popularity.current_page=1; by_popularity.per_page=4; $(function(){ $('.previous.active').live('click',function(){ window[current_obj].current_page--; process(window[current_obj]); }); }); function process(game_obj){ //will process and output new items here } </script> <div class="otherContainer"> <a class='previous active'>Prev</a><div style="display:none;">by_date</div> | <a class='next'>Next</a><div style="display:none;">by_date</div> </div> <div class="topPrevNextContainer"> <a class='previous active'>Prev</a><div style="display:none;">by_popularity</div> | <a class='next'>Next</a><div style="display:none;">by_popularity</div> </div>

  • How to customize the content of each page using Page Control and UIScrollView?

    - by viper15
    I have problem with customizing each page using pagecontrol and UIScrollView. I'm customizing Page Control from Apple. Basically I would like to have each page different with text and image alternately on different page. Page 1 will have all text, Page 2 will have just images, Page 3 will have all text and goes on. This is original code: // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; } As you can see, this code shows only Page 1, Page 2 etc as you scroll right. I tried to put in this new code but that didn't make any difference. There's no error. I know this is pretty simple code. I don't why it doesn't work. I declare pageText as UILabel. // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; if (pageNumber == 1) { pageText.text = @"Text in page 1"; } if (pageNumber == 2) { pageText.text = @"Image in page 2"; } if (pageNumber == 3) { pageText.text = @"Text in page 3"; } } I don't know why it doesn't work. Also if you have better way to do it, let me know. Thanks.

  • jQuery Colorbox Iframe and Selector

    - by Joker
    I have this: $("a.money").colorbox({href:$("a.money").attr("href")+" div#content"}); Which opens an overlay but only of the content within the #content selector. If I add iframe:true, this will no longer work. Is there a way to get it to work with an iframe? Edit: The closest I could get it to work was by doing this: $("a.money").colorbox({iframe:true, width:700, height:425, onComplete: function() { alert('test'); $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); Although without the alert it doesn't appear to work, I looked into that and I think I need to use .live(), which led me to trying this: $('a.money').live('click', function() { url = this.href; // this is the url of the element event is triggered from $.fn.colorbox({href: url, iframe:true,width:700, height:425, onComplete: function() { $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); return false; }); Didn't work, I still needed to add an alert to make it work. In case you might be wondering what I'm trying to do. The webpage is loaded in the iframe, with all the elements in the #container, so that includes #header, #sidebars, but I only want to show the #content inside the iframe. However, this led me to another problem I realized. Assuming I got this to work without the alert, it will only work for that initial page. For example, if I loaded up a form in the iframe, after submitting the form, I would once again see the whole layout instead of just the #content portion. Is it possible to continue only showing the #content portion of the page upon further navigation?

  • Apache virtualhost - only apply script if file does not exist in document root

    - by Brett Thomas
    Sorry for the newbie apache question. I'm wondering if it's possible to set up the following non-conventional apache virtualhost (for a Django app): -- If a file exists in the DocumentRoot (/var/www) it will be shown. So if /var/www/foo.html exists, then it can be seen at www.example.com/foo.html. -- If file does not exist, it is served via a virtualhost. I'm using mod_wsgi with a WSGIScriptAlias directive that points to a Django app. So if there is no /var/www/bar.html, www.example.com/bar.html will be passed to the Django app, which may or may not be a 404 error. One option is to create an Alias for each individual file/directory, but people want to be able to post a file without adding an alias, and we want to keep the above URL structure for legacy reasons. Simplified Virtualhost is: <VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www WSGIScriptAlias / /path/to/django.wsgi <Directory /path/to/app> Order allow,deny Allow from all </Directory> Alias /hi.html /var/www/hi.html </VirtualHost> The goal is to have www.example.com/hi.html work as above, without the Alias line

  • When dynamically adding nodes to DOM how to make browser repaint the background to avoid artefacts?

    - by Tim
    Given nested DIVs: <div id="outer" <div id = "inner" > <div id = "injectedcontent"> nodes are added to this DIV with </div> </div> </div> and this css: #outer {background-color: lightgrey; padding: 2em; width: 100%; height: 100%} #inner {background-color: white; width: 100%; height: 100%} and content injected in this manner: function injectContent(titleDivId, content){ var resultscontainer=document.getElementById('injectedcontent'); var titleDiv = document.getElementById(titleDivId); if (titleDiv == null) { titleDiv=document.createElement('div'); titleDiv.id=titleDivId; titleDiv.innerHTML += content; resultscontainer.appendChild(titleDiv); } else { titleDiv.innerHTML += content; } } the browsers do not redraw the outer DIV's background to accommodate the injected content. When I scroll the page (lots of text gets injected into the page -- it is a full-text search app) the lightgray background is painted right across the text, as shown in the attached image. Is there a way to cause the browser to recalculate page-depth after injecting content? Or is this problem related to this line: titleDiv.innerHTML += content; Is it better to add titleDiv's content a node at a time? I've recently seen respected people using innerHTML in this way, although postings from from several years ago discourage use of innerHTML. 1:

  • Is it possible to embed Cockburn style textual UML Use Case content in the code base to improve code

    - by fooledbyprimes
    experimenting with Cockburn use cases in code I was writing some complicated UI code. I decided to employ Cockburn use cases with fish,kite,and sea levels (discussed by Martin Fowler in his book 'UML Distilled'). I wrapped Cockburn use cases in static C# objects so that I could test logical conditions against static constants which represented steps in a UI workflow. The idea was that you could read the code and know what it was doing because the wrapped objects and their public contants gave you ENGLISH use cases via namespaces. Also, I was going to use reflection to pump out error messages that included the described use cases. The idea is that the stack trace could include some UI use case steps IN ENGLISH.... It turned out to be a fun way to achieve a mini,psuedo light-weight Domain Language but without having to write a DSL compiler. So my question is whether or not this is a good way to do this? Has anyone out there ever done something similar? c# example snippets follow Assume we have some aspx page which has 3 user controls (with lots of clickable stuff). User must click on stuff in one particular user control (possibly making some kind of selection) and then the UI must visually cue the user that the selection was successful. Now, while that item is selected, the user must browse through a gridview to find an item within one of the other user controls and then select something. This sounds like an easy thing to manage but the code can get ugly. In my case, the user controls all sent event messages which were captured by the main page. This way, the page acted like a central processor of UI events and could keep track of what happens when the user is clicking around. So, in the main aspx page, we capture the first user control's event. using MyCompany.MyApp.Web.UseCases; protected void MyFirstUserControl_SomeUIWorkflowRequestCommingIn(object sender, EventArgs e) { // some code here to respond and make "state" changes or whatever // // blah blah blah // finally we have this (how did we know to call fish level method?? because we knew when we wrote the code to send the event in the user control) UpdateUserInterfaceOnFishLevelUseCaseGoalSuccess(FishLevel.SomeNamedUIWorkflow.SelectedItemForPurchase) } protected void UpdateUserInterfaceOnFishLevelGoalSuccess(FishLevel.SomeNamedUIWorkflow goal) { switch (goal) { case FishLevel.SomeNamedUIWorkflow.NewMasterItemSelected: //call some UI related methods here including methods for the other user controls if necessary.... break; case FishLevel.SomeNamedUIWorkFlow.DrillDownOnDetails: //call some UI related methods here including methods for the other user controls if necessary.... break; case FishLevel.SomeNamedUIWorkFlow.CancelMultiSelect: //call some UI related methods here including methods for the other user controls if necessary.... break; // more cases... } } } //also we have protected void UpdateUserInterfaceOnSeaLevelGoalSuccess(SeaLevel.SomeNamedUIWorkflow goal) { switch (goal) { case SeaLevel.CheckOutWorkflow.ChangedCreditCard: // do stuff // more cases... } } } So, in the MyCompany.MyApp.Web.UseCases namespace we might have code like this: class SeaLevel... class FishLevel... class KiteLevel... The workflow use cases embedded in the classes could be inner classes or static methods or enumerations or whatever gives you the cleanest namespace. I can't remember what I did originally but you get the picture.
