If you require lots of forms in your project and do not want to be creating an extended template for each one I propose this solution. Classes in the html correspond to bootstrap, you can work without them if you do not use bootstrap.
Renders an select field with some optgroups. Some options can be outside the optgroup(s). The options and labels should be in a tuple with ((label, choices),) where choices is a tuple ((key, value), (key2, value2)). If a label is null or blank, the options will not belong to an opt group.
I needed a way to find if a menu items should be active. After searching the internet i found a few options*, but none of them did fit my needs, so i wrote my own: Usage: <a href="{% url 'view-name' %}" class="{% current request 'view-name' %}"></a> * http://gnuvince.wordpress.com/2008/03/19/the-new-and-improved-active-tag/ * http://stackoverflow.com/questions/340888/navigation-in-django
People -- and by "people" I mean Jeff Croft -- often ask about how to split a list into multiple lists (usually for presenting as columns in a template). These template tags provide two different ways of splitting lists -- on "vertically", and the other "horizontally".
WTForm is an extension to the django newforms library allowing the developer, in a very flexible way, to layout the form fields using fieldsets and columns WTForm was built with the well-documented [YUI Grid CSS](http://developer.yahoo.com/yui/grids/) in mind when rendering the columns and fields. This should make it easy to implement WTForm in your own applications. Here is an image of an [example form rendered with WTForm](http://www.gmta.info/files/wtform.png).
An easy way of making inlines orderable using drag-and-drop, using [jQuery UI's](http://ui.jquery.com/) sortable() plugin. First, add an "order" field to the inline models which is an IntegerField, and set that model to use 'order' as its default order_by. Then hook in the JavaScript. This should make them drag-and-drop sortable using jQuery UI, and also hide the divs containing those order fields once the page has loaded. This technique is unobtrusive: if JavaScript is disabled, the order fields will be visible and the user will be able to manually set the order by entering numbers themselves.

Takes a tweet url, requests the json from Twitter oEmbed, parses the json for the html element and returns it to your template. The html returned is ready to go and will be shown as a tweet on your web page. This uses the Requests library for Python. A full example can be found on GitHub https://github.com/z3ke1r/django-tweet-embed.
Requires to install "basicauth" package, which does basic-auth header encoding/decoding cleanly according to RFCs. Could be improved to return a "realm" in case of http401, like in https://djangosnippets.org/snippets/1720/, although I'm not sure it's really useful in django usecases.
A simple backend which allows you to login with either an email address or a username. It should be combined with another backend for checking permissions: AUTHENTICATION_BACKENDS = ( 'myproject.accounts.backends.EmailOrUsernameModelBackend', 'django.contrib.auth.backends.ModelBackend' )
Small fix to make https://www.djangosnippets.org/snippets/1779/ compatible with Django 1.11 To use this you'll also need the javascript from https://www.djangosnippets.org/snippets/1780/ I added an overridden optgroups method that can handle the additional tuple and a couple minor things I gathered while investigating for a fix (a default level_indicator of "+--" and changed paths for the JS files. All credits goes to @anentropic :-)
Handles creation of `order_by` criteria based on GET parameters and provides context variables to be used when generating table header sort links which respect the current sort field and direction, reversing the direction when the same header is sorted by again. Sample view: from somewhere import SortHeaders from django.contrib.auth.models import User from django.shortcuts import render_to_response LIST_HEADERS = ( ('Username', 'username'), ('First Name', 'first_name'), ('Last Name', 'last_name'), ('Email', None), ) def user_list(request): sort_headers = SortHeaders(request, LIST_HEADERS) users = User.objects.order_by(sort_headers.get_order_by()) return render_to_response('users/user_list.html', { 'users': users, 'headers': list(sort_headers.headers()), }) Sample template: {% load my_tags %} <table cellspacing="0"> <thead> <tr> {% table_header headers %} </tr> </thead> <tbody> {% for user in users %}<tr class="{% cycle odd,even %}"> <td><a href="{{ user.get_absolute_url|escape }}">{{ user.username|escape }}</a></td> <td>{{ user.first_name|escape }}</td> <td>{{ user.last_name|escape }}</td> <td>{{ user.email|escape }}</td> </tr> {% endfor %} </tbody> </table> Sample inclusion tag: from django import template def table_header(context, headers): return { 'headers': headers, } register = template.Library() register.inclusion_tag('table_header.html', takes_context=True)(table_header) Sample inclusion tag template: {% for header in headers %}<th{{ header.class_attr }}> {% if header.sortable %}<a href="{{ header.url|escape }}">{% endif %} {{ header.text }} {% if header.sortable %}</a>{% endif %} </th>{% endfor %}
The idea here is to wrap the original `delete_selected` functionality in a way that I shouldn't have to reimplement the templates (confirmation/error response) serving, just extend the original. What this code does, it wraps the queryset's delete function with a closure, so when it really gets called (after the confirmation), it executes the extra functionality you wish to. After looking at the original code, this seemed to be the most efficient way of doing it.
Django's CharField requires a max_length, and TextField displays a multi- line widget, but in Postgres there's no reason to add an arbitrary max thanks to the `varlena` storage format. So this is a TextField that displays as a single line instead of a multiline TextArea.
