• How do I determine what branch/tag I have checked out in git?

  - by Avry

  I clone my source using git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git w/. Then I specify a specific branch/tag by doing git checkout <tag name> or git checkout origin/REL<release number>. Sometimes I forget what branch or tag I'm on. In SVN I would do a svn info to figure out what branch/tag I'm using (I realize that git has distinct definitions for branch and tag but for my purposes they are the same). How do I determine what branch/tag I am on?

• Django, url tag in template doesn't work: NoReverseMatch

  - by Lukasz Jocz

  I've encountered a problem with generating reverse url in templates in django. I'm trying to solve it since a few hours and I have no idea what the problem might be. URL reversing works great in models and views: # like this in models.py @models.permalink def get_absolute_url(self): return ('entry', (), { 'entry_id': self.entry.id, }) # or this in views.py return HttpResponseRedirect(reverse('entry',args=(entry_id,))) but when I'm trying to make it in template I get such an error: NoReverseMatch at /entry/1/ Reverse for ''add_comment'' with arguments '(1L,)' and keyword arguments '{}' not found. My file structure looks like this: project/ +-- frontend ¦   +-- models.py ¦   +-- urls.py ¦   +-- views.py +-- settings.py +-- templates ¦   +-- add_comment.html ¦   +-- entry.html +-- utils ¦   +-- with_template.py +-- wsgi.py My urls.py: from project.frontend.views import * from django.conf.urls import patterns, include, url urlpatterns = patterns('project.frontend.views', url(r'^entry/(?P<entry_id>\d+)/', 'entry', name="entry"), (r'^entry_list/', 'entry_list'), Then entry_list.html: {% extends "base.html" %} {% block content %} {% for entry in entries %} {% url 'entry' entry.id %} {% endfor %} {% endblock %} In views.py I have: @with_template def entry(request, entry_id): entry = Entry.objects.get(id=entry_id) entry.comments = entry.get_comments() return locals() where with_template is following decorator(but I don't think this is a case): class TheWrapper(object): def __init__(self, default_template_name): self.default_template_name = default_template_name def __call__(self, func): def decorated_func(request, *args, **kwargs): extra_context = kwargs.pop('extra_context', {}) dictionary = {} ret = func(request, *args, **kwargs) if isinstance(ret, HttpResponse): return ret dictionary.update(ret) dictionary.update(extra_context) return render_to_response(dictionary.get('template_name', self.default_template_name), context_instance=RequestContext(request), dictionary=dictionary) update_wrapper(decorated_func, func) return decorated_func if not callable(arg): return TheWrapper(arg) else: default_template_name = ''.join([ arg.__name__, '.html']) return TheWrapper(default_template_name)(arg) Do you have any idea, what may cause the problem? Great thanks in advance!

• Spring 3.0 MVC mvc:view-controller tag

  - by gouki

  Here's a snippet of my mvc-config.xml <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:view-controller path="/index" view-name="welcome"/> <mvc:view-controller path="/static/login" view-name="/static/login"/> <mvc:view-controller path="/login" view-name="/static/login"/> I have the welcome.jsp on /WEB-INF/view/ directory and login.jsp on /WEB-INF/view/static/. This work for '/index' and '/login' paths. But I'm getting 404 response for '/static/login' when invoked from the browser. I'm expecting that '/static/login/' and '/login' should behave the same. What could be wrong here? Would appreciate any help. Thanks!

• Accessing XML/PHP with period in tag

  - by LuckyShot

  Hi guys, Quick newbie question here, how do I access totalResults? XML <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription> <opensearch:totalResults>1</opensearch:totalResults> <posts> <post> <score>10</score> </post> </posts> </OpenSearchDescription> To access the score I would do this: PHP $xmlObj = simplexml_load_string($theXMLabove); echo $xmlObj->posts->post[0]->score; But none of these work for the totalResults: echo $xmlObj->opensearch:totalResults; echo $xmlObj->opensearch->totalResults; Sorry for asking such a lame question... Documentation on how to traverse XML with PHP is also appreciated :) Thanks!

• Match e-mail addresses not contained in HTML tag

  - by SvartalF

  I need to highlight an email addresses in text but not highlight them if contained in HTML tags, content, or attributes. For example, the string [email protected] must be converted to <a href="mailto:[email protected]">[email protected]</a> But email addresses in the string <a href="mailto:[email protected]">[email protected]</a> must not be processed. I've tried something like this regexp: (?<![":])[a-zA-Z0-9._%-+]+@[a-zA-Z0-9._%-]+.[a-zA-Z]{2,6}(?!") but it doesn't work properly.

• Find whether a particular cell of a table has an img tag

  - by SilentPro

  I am generating a table dynamically using Django. The same table template is used to generate a variety of tables depending on the data supplied. In one scenario a particular column contains image tags. Since my table is editable (using jquery) the image cell also becomes editable and removes my content. I want some special behavior on double click of such cells like say upload an image. How do I accomplish this with a jquery? My script for making the table editable is given below. $(function() { $("td").dblclick(function() { var OriginalContent = $(this).text(); $(this).addClass("cellEditing"); $(this).html("<input type='text' value='" + OriginalContent + "' />"); $(this).children().first().focus(); $(this).children().first().keypress(function(e) { if (e.which == 13) { var newContent = $(this).val(); $(this).parent().text(newContent); $(this).parent().removeClass("cellEditing"); } }); $(this).children().first().blur(function() { $(this).parent().text(OriginalContent); $(this).parent().removeClass("cellEditing"); }); }); });

• dynamic text in <h1> tag

  - by Ami

  what would be the impact on SEO of changing the text of the <h1> dynamically on the server side each time the web page loads? I'm not talking about changing the whole text, just part of it, for example if the header contains some fixed text (with keywords of course), and also contains the current date or time/the current number of logged on users/the count of items current in stock/whatever. how would that affect my ranking? is it bad? doesn't make a difference? thanks.

• Dynamically Changing an img tag's onemouseover attribute with Javascript nulls it instead

  - by ?s?zs?

  I want to create an img that has four different states: State 1 over State 1 out State 2 over State 2 out Each state is a different image, and the user can toggle between states 1 and 2 by clicking on the image. To do this I change the src when the image is clicked and the onmouseover and onmouseout attributes of the img element. However when the attributes have been changed they become nulled and do nothing. How can I dynamically change these properties? Here is the code I am using: <!DOCTYPE html> <html> <head> <script> function change() { document.getElementById('image').src="http://youtube.thegoblin.net/layoutFix/hideplaylist.png"; document.getElementById('image').onmouseover="this.src='http://youtube.thegoblin.net/layoutFix/hideplaylistDark.png'"; document.getElementById('image').onmouseout="this.src='http://youtube.thegoblin.net/layoutFix/hideplaylist.png'"; } </script> </head> <body> <img id="image" src="http://youtube.thegoblin.net/layoutFix/showplaylist.png" onmouseover="this.src='http://youtube.thegoblin.net/layoutFix/showplaylistDark.png'" onmouseout="this.src='http://youtube.thegoblin.net/layoutFix/showplaylist.png'" onClick="change()"> </body> </html>

• innerHTML within another tag

  - by jimbo

  Hi all, I have a link: <a id="nextBut" href="somelink" class="button"><span>Next Step</span></a> And I can control the the <span>Next step</span> part with innerHTML but how could I leave the <span> alone and just change the 'Next step' part? For example: var NextButJar = document.getElementById('nextBut'); NextButJar.disabled = true; NextButJar.style.opacity = .5; NextButJar.span.innerHTML = 'Read all tabs to continue'; I also have: NextButJar.onClick = handleClick; function handleClick(){ if (this.disabled == true) { alert("Please view all tabs first!"); return; } else { alert("allowed to run"); } }; Which I can't seem to get working either...

• Rails and the <span> tag

  - by Zachary

  I'm fairly new to Ruby on Rails, and I'm attempting to create some fancy CSS buttons using the "sliding doors" technique. I have it almost working, but I feel like there has to be a better way to handle the tags for a link. The way I'm currently doing it: <%= link_to '<span>New car</span>', {:action => "new"}, :class=>"button" %> This isn't terrible, per se, but I would like to know if this is the best way to handle span tags is RoR.

  I am working on and Microsoft MVC3 project and cannot pass a parameter which has been edited to the controller. It will only pass back the original set parameter For example: @Ajax.ActionLink("share file", InviteController.Actions.Result, InviteController.Name, new { message = Model.Message }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "popup", OnSuccess = "$('#popup').dialog('open')" }, new { id = "popup-button" }) <label>Personal Message <span class="optional-message">(optional)</span></label> @Html.TextAreaFor(x => x.Message) </div> This will pass the to the following controller but the 'message' parameter has the original message and not the updated message: public ActionResult Result(FormCollection coll, string message) { I'd love if someone could give me some advice.

• JavaScript: Changing src-attribute of a embed-tag

  - by Mike

  I have the following scenario. I show the user some audio files from the server. The user clicks on one, then onFileSelected is eventually executed with both the selected folder and file. What the function does is change the source from the embedded object. So in a way, it is a preview of the selected file before accepting it and save the user's choice. A visual aid. HTML <embed src="/resources/audio/_webbook_0001/embed_test.mp3" type="audio/mpeg" id="audio_file"> JavaScript function onFileSelected(file, directory) { jQuery('embed#audio_file').attr('src', '/resources/audio/'+directory+'/'+file); }; Now, this works fine in Firefox, but Safari and Chrome simply refuse to change the source, regardless of Operating System. jQuery finds the object (jQuery.size() returns 1), it executes the code, but no change in the HTML Code. Why does Safari prevent me from changing the <embed> source and how can I circumvent this?
