  • Automatically use inclusion tags (?) in a template, depending on installed apps

    - by Ludwik Trammer
    The title may be a little confusing, but I don't know how else to call it. I would like to create a Django project with a large set of applications you could arbitrary turn on or off using INSTALLED_APPS option in settings.py (you would obviously also need to edit urls.py and run syncdb). After being turned on an app should be able to automatically: Register it's content in site-wide search. Luckily django-haystack has this built-in, so it's not a problem. Register cron jobs. django-cron does exactly that. Not a problem. Register a widget that should be displayed on the homepage. The homepage should include a list of boxes with widgets form different applications. I thought about inclusion tags, because you can put them anywhere on a page and they control both content and presentation. The problem is I don't know how to automatically get a list of inclusion tags provided by my applications, and display them one by one on a homepage. I need a way to register them somehow, and then display all registered tags.

  • Which method of 'clearfix' is best?

    - by Pickledegg
    I have the age old problem of a div wrapping a 2 column layout. My sidebar is floated so my container div fails to wrap the content & sidebar. <div id="container"> <div id="content"> </div> <div id="sidebar"> </div> </div> There seem to be numerous methods of fixing the clear bug in FF: <br clear="all"/> overflow:auto overflow:hidden etc. But in my situation, the only one that seems to work correctly is the <br clear="all"/> solution, which is a little bit scruffy. overflow:auto gives me nasty scrollbars, and overflow:hidden must surely have side effects. Also, apparently IE7 is supposed to not suffer from this problem due to its incorrect behaviour, but again, in my situation its suffering the same as FF. Whats the most reliable/best practice method currently available to us?

  • Download a file using cocoa

    Hi All, I want to download a file to the downloads folder. I searched google for this and found the NSURLDownload class.

  • Vertical text in a Horizontal UIButton

    - by ArQangel
    I'm using a vertical UIButton in a portrait app (Just a normal button that is of width 60 and Height 160) I want to put the label Vetically down the button instead of across it. When I use the following code to rotate the label [workPackageButton.titleLabel setTransform:CGAffineTransformMakeRotation(M_PI / 2)]; It rotates the label but the length seems to be constrained by the original width, so I get the ... abreviation in the middle. Is there an easy way round this?

  • Trouble accessing data in relationships in Ember

    - by user3618430
    I'm having trouble saving data in this model relationship. My models are as follows: App.Flow = DS.Model.extend({ title: DS.attr('string'), content: DS.attr('string'), isCustom: DS.attr('boolean'), params: DS.hasMany('parameter', {async: true}) }); App.Parameter = DS.Model.extend({ flow: DS.belongsTo('flow'), param: DS.attr('string'), param_tooltip: DS.attr('string'), param_value: DS.attr('string') }); As you can see, I want Flows to have multiple Parameters. I have a rudimentary setup using Flow and Parameter fixtures, which behave as expected in the templates. However, when I try to create new ones in the controller, I have trouble setting the flow and parameter values correctly. var p = this.store.createRecord('parameter', { param: "foo", param_tooltip: "world", param_value: "hello" }); var f = this.store.createRecord('flow', { title: 'job', content: title, isCustom: true, params: [p] // doesn't seem to work }); f.set('params', [p]); // doesn't seem to work p.set('flow', f); // also doesn't seem to work // Save the new model p.save(); f.save(); I've tried a lot of solutions after staring at this and StackOverflow for a while (not just the ones listed). I'm not really sure what to try next. One thing that I noticed in the Ember inspector was that the ids of these created elements were not integers (they were something like the string 'fixture_0'), but I'm not really sure why that would be, whether its related, or how to fix it. Thanks!

  • Html image link, not working

    - by Anders Metnik
    Hey I'm doing some testing while learning js + html5 and other web/mobile frameworks. I have a problem with one of my picture links, which I also need to change the picture dynamically and the target(hopefully). But it won't work. HTML: <div data-role="content" id="firstPageContent"> <p>I'm first in the source order so I'm shown as the page.</p> <p>View internal page called <a href="#second">second</a></p> <a href = "#second" id="mapLink" name="mapLink"><img id="mapLinkImage" alt="a map which links to the mapPage" src="images/main_header.png"/></a> <Button id="loadButton" onClick="load()"/> </div><!-- /content --> js: importScripts(dataManager.js); var mapLink=second; function load(){ alert('called'); document.getElementById('mapLinkImage').src="images/store.map.png"; document.getElementById('mapLink').href = "http://google.com"; } problem: It ain't showing the image as a link, just as a plain image. i think this will work now.

  • What is the best way to do Bit Field manipulation in Python?

    - by ZebZiggle
    I'm reading some MPEG Transport Stream protocol over UDP and it has some funky bitfields in it (length 13 for example). I'm using the "struct" library to do the broad unpacking, but is there a simple way to say "Grab the next 13 bits" rather than have to hand-tweak the bit manipulation? I'd like something like the way C does bit fields (without having to revert to C). Suggestions?

  • Ruby Regexp methods?

    - by fjs6
    Is there a gem/example_code that allows to work with regexps? I am not looking for what a regexp can do, but what can be done to a Regexp object. For example: r = Regexp.new(...) r.min_length => the minimum length of a matching string r = Regexp.new("car(less)?") r.min_length => 3 for the string "car" Thanks!

  • dojo.parser.parse only working first time it's called.

    - by crazymerlin
    I have a page that when a user clicks on a link for some reporting tools, it first asks them to enter some report parameters. I get the parameters dialog as a form using AJAX, based on the id of the link. Each dialog has some dojo controls on it, so I need to parse them when the dialog appears, because it is not originally part of the page. The first dialog when called works fine, but subsequent calls to dialogs fails to parse the dojo controls. Example: showParametersDialog : function(doc) { var content = doc.firstChild.firstChild.data; var container = document.createElement('div'); container.id = 'dialog'; container.innerHTML = content; container.style.background = 'transparent'; container.style.position = 'absolute'; container.style.top = (document.body.clientHeight / 2) - 124 + "px"; container.style.left = (document.body.clientWidth / 2) - 133 + "px"; container.style.display = 'block'; document.body.appendChild(container); // set up date fields var date_from = dojo.byId('date_from'); var date_to = dojo.byId('date_to'); try { date_from.value = dojo.date.locale.format(new Date(), {selector: 'date'}); date_to.value = dojo.date.locale.format(new Date(), {selector: 'date'}); } catch(e) { var now = new Date(); date_from.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); date_to.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); } dojo.parser.parse(); } All dialogs have the common date fields. So when I call this dialog the first time, and dojo.parser.parse() is called, it parses the controls on the dialog, but only the first time...after than, no dojo. Any thoughts? Thanks, Paul.

  • Acessing a wordpress database from an iPhone App.

    - by Code
    Hi guys, I've been asked to create an app that will get data back from a database where the CMS will be Wordpress. I've never used a CMS so I'm trying to get a (overview)picture in my head of how it could all work and what each of the components would be. And what a CMS actually brings to the party. Creating the app itself is pretty clear. I've done a few already. I've made a database before and shouldnt cause a problem. But what is going to be in the middle between the app and the database? Part A: I'm guessing iphone apps typically would call some php file that's hosted on the server? The php then would make a call to the database and return the data somehow, maybe as xml. But this is really basic and wouldnt require a CMS. Just a database and a phpfile, or am I wrong? Part B: If i wanted to run a check on the database every minute to see if any of the data in database was no longer valid and remove it if needed, that would require somekind of program running on the server. So that program would be Wordpress, since it is managing the content, so a content management system is actually needed and is for these kind of taskes. Am i understanding the role of CMS? Many Thanks, -Code

  • How can I bind multiple Jquery UI Slider with "year" Select?

    - by arthur_br
    Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  • C++ exam question on string class implementation

    - by Carlucho
    I just took an exam where i was asked the following: Write the function body of each of the methods GenStrLen, InsertChar and StrReverse for the given code bellow. You must take into consideration the following; How strings are constructed in C++ The string must not overflow Insertion of character increases its length by 1 An empty string is indicated by StrLen = 0 class Strings { private: char str[80]; int StrLen; public: // Constructor Strings() { StrLen=0; }; // A function for returning the length of the string 'str' int GetStrLen(void) { }; // A function to inser a character 'ch' at the end of the string 'str' void InsertChar(char ch) { }; // A function to reverse the content of the string 'str' void StrReverse(void) { }; }; The answer I gave was something like this (see bellow). My one of problem is that used many extra variables and that makes me believe am not doing it the best possible way, and the other thing is that is not working.... class Strings { private: char str[80]; int StrLen; int index; // *** Had to add this *** public: Strings(){ StrLen=0; } int GetStrLen(void){ for (int i=0 ; str[i]!='\0' ; i++) index++; return index; // *** Here am getting a weird value, something like 1829584505306 *** } void InsertChar(char ch){ str[index] = ch; // *** Not sure if this is correct cuz I was not given int index *** } void StrRevrse(void){ GetStrLen(); char revStr[index+1]; for (int i=0 ; str[i]!='\0' ; i++){ for (int r=index ; r>0 ; r--) revStr[r] = str[i]; } } }; I would appreciate if anyone could explain me toughly what is the best way to have answered the question and why. Also how come my professor closes each class function like " }; " i thought that was only used for ending classes and constructors only. Thanks a lot for your help.

  • PHP mail function, some clients aren't showing my mails as html?

    - by Don
    I'm trying to send emails to my website members using the mail() function with PHP, The mails are in hebrew, and I want to send an html email, That's pretty much how I send it $mail_to = "[email protected]"; $message = " <html> some content here </html> "; $headers = "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=windows-1255" . "\r\n"; $headers .= 'From: "MyWebsiteName" <[email protected]>' . "\r\n"; $mail = mail($mail_to, $subject, $message, $headers ); It works completely fine with clients such as Gmail, or thunderbird users, but I viewed it in a few other clients, that aren't so famous, but still widely used in my country, and it just shows me the html source.. I'll also add that I've seen other mails in those clients that are working fine, so they are supporting html mails. What am I doing wrong?

  • JavaScript (via Greasemonkey) failing to set "title" attributes on <a> tags

    - by rjray
    I have the following (fairly) simple JavaScript snippet that I have wired into Greasemonkey. It goes through a page, looks for <a> tags whose href points to tinyurl.com, and adds a "title" attribute that identifies the true destination of the link. Much of the important code comes from an older (unsupported) Greasemonkey script that quits working when the inner component that held the XPath implementation changed. My script: (function() { var providers = new Array(); providers['tinyurl.com'] = function(link, fragment) { // This is mostly taken from the (broken due to XPath component // issues) tinyurl_popup_preview script. link.title = "Loading..."; GM_xmlhttpRequest({ method: 'GET', url: 'http://preview.tinyurl.com/' + fragment, onload: function(res) { var re = res.responseText.match("<blockquote><b>(.+)</b></blockquote>"); if (re) { link.title = re[1].replace(/\<br \/\>/g, "").replace(/&amp;/g, "&"); } else { link.title = "Parsing failed..."; } }, onerror: function() { link.title = "Connection failed..."; } }); }; var uriPattern = /(tinyurl\.com)\/([a-zA-Z0-9]+)/; var aTags = document.getElementsByTagName("a"); for (i = 0; i < aTags.length; i++) { var data = aTags[i].href.match(uriPattern); if (data != null && data.length > 1 && data[2] != "preview") { var source = data[1]; var fragment = data[2]; var link = aTags[i]; aTags[i].addEventListener("mouseover", function() { if (link.title == "") { (providers[source])(link, fragment); } }, false); } } })(); (The reason the "providers" associative array is set up the way it is, is so that I can expand this to cover other URL-shortening services as well.) I have verified that all the various branches of code are being reached correctly, in cases where the link being examined does and does not match the pattern. What isn't happening, is any change to the "title" attribute of the anchor tags. I've watched this via Firebug, thrown alert() calls in left and right, and it just never changes. In a previous iteration all expressions of the form: link.title = "..."; had originally been: link.setAttribute("title", "..."); That didn't work, either. I'm no newbie to JavaScript OR Greasemonkey, but this one has me stumped!

  • jQuery select image in div if image parent does't have a certain class.

    - by Alex
    Wordpress wraps images with captions in a div with a class of .wp-caption. I'm looking for a way to select images that don't have this div so I can wrap them in different div. (to keep a consistent border around all the images) <div class="blog-post-content"> <div id="attachment_220" class="wp-caption alignleft" style="width: 310px"> <a href="/somewhere/"><img class="size-medium wp-image-220" src="/path/to/image" alt="" width="300" height="280" /></a> <p class="wp-caption-text">Caption Text</p> </div> <p>This is the body of the post</p> </div> To test my selector, I'm just trying to add a green border. I can handle the .wrap() once the selector is working. The most promising of my attempts is: $('.blog-post-content img').parent('div:not(".wp-caption")').css('border', '2px solid green'); ... but no luck.

  • Android Service setForeground While Display Sleeps

    - by c12
    I have a background Android Service that's purpose is to communicate with another device (non-phone) using a Bluetooth socket. Everything works fine except that the service gets stopped and restarted by the OS when the phone display is sleeping. This restart sometimes leaves a 15-20 minute gaps where there is no communication between the Service and the Bluetooth device and I need to be able to query the device every minute. Is startForeground the proper approach? Attempted to use: startForeground(int, Notification) //still see gaps when phone sleeps Service: public class ForegroundBluetoothService extends Service{ private boolean isStarted = false; @Override public void onDestroy() { super.onDestroy(); stop(); } /** * @see android.app.Service#onBind(android.content.Intent) */ @Override public IBinder onBind(Intent intent) { return null; } /** * @see android.app.Service#onStartCommand(android.content.Intent, int, int) */ @Override public int onStartCommand(Intent intent, int flags, int startId) { loadServiceInForeground(); return(START_STICKY); } private void loadServiceInForeground() { if (!isStarted) { isStarted=true; Notification notification = new Notification(R.drawable.icon, "Service is Running...", System.currentTimeMillis()); Intent notificationIntent = new Intent(this, MainScreen.class); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(this, "Notification Title", "Service is Running...", pendingIntent); startForeground(12345, notification); try{ queryTheBluetoothDevice(); } catch(Exception ex){ ex.printStackTrace(); } } } private void stop() { if (isStarted) { isStarted=false; stopForeground(true); } } }
