WTForm (What The Form)
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).

Single Django App behind multiple Apache Proxies
** Django Proxied Behind Apache Path** Middleware and Context Processor for django applications behind a proxy like Apache's mod_proxy. Setting an HTTP header with the base path of the django application in the Apache mod_proxy configuration, we can pull that variable out of the request and adjust our template URIs and redirects. This allows us to serve the same Django application out from behind multiple VirtualHosts at different URL paths. Example use in templates: <a href="{{ base_path }}/login/">Login</a> Example Apache configuration: <LocationMatch ^/path/to/django/app/.*> RequestHeader set X-Base-Path "/path/to/django/app" </LocationMatch> RewriteRule ^/path/to/django/app/(.*) http://django-host:8080/$1 [P,L] In settings.py: VHOST_HEADER = "HTTP_X_BASE_PATH"

youtubize template tag
This snippet is based on djangos urlize filter. It converts http:// links to youtube into youtube-embed statements, so that one can provide a simple link to a youtube video and this filter will embed it. I used it for a fun blog app.

split filter
**Usage** (*in template*): <img src="{{ MEDIA_URL }}2007/images/{% filter split:","|random %}theimage1.jpg,something2.jpg,thirdisthecharm.jpg{% endfilter %}" /> I decided to make it simple, because one template creator wanted to add random images to different places of templates. Creating something huge, like external image filename parsing was not necessary in this case.

Timedelta template tag
This is tag similar to *timesince* and *timeuntil*, which work great until you starting giving timesince dates in the future or timeuntil dates in the past. Timedelta tag will humanize output correctly for both future and past dates using *now* as a default reference date (or a specified reference date as argument) now = Apr 27 2007 futuredate = May 5 2007 pastdate = Jan 5 2007 {{ futuredate|timedelta }} will output "in 1 week, 1 day" {{ pastdate|timedelta }} will output "3 months, 2 weeks ago"

newforms field callback helper
**Now redundant any anything >0.96**, as `form_for_*` methods now have a `fields` attribute `formfield_callback`s are a bit difficult to use, here's a helper method to create a callback function to use with the `form_for_instance` and `form_for_model` methods. Example usage: person_callback = new_callback(exclude=['password', 'can_add_staff', 'is_staff']) def form_for_person(person): return form_for_instance(person, formfield_callback=person_callback)

Custom SQL Function; Outputs Template-Friendly Content
This will return a template-friendly list of dictionaries when using custom SQL. The dictionary can be accessed just as a normal model/queryset. Example of use (in view): qkeys = ['artist','album'] query = """ SELECT "artist","album" FROM "music" """ new_list = csql(request,query,qkeys) (in template) {% for row in new_list %} {{ row.artist }} {{ row.album }} {% endfor %}

Name Capitalize Filter
This is to be used as a template filter. See [django documentation](http://www.djangoproject.com/documentation/templates_python/#writing-custom-template-filters) for adding custom filters. Example of use: name = "bart simpson" `{{ name|cap }}` will convert 'name' to "Bart Simpson" It works on space-separated names, as well as the following: * converts "mcfly" to "McFly"; * converts "o'neill" to "O'Neill"; * converts "barker-bradley" to "Barker-Bradley"

Sanitize HTML filter
Originally posted by [akaihola](http://www.djangosnippets.org/users/akaihola/) as [snippet #169](http://www.djangosnippets.org/snippets/169/). I just redid it as a filter.

RequestStack middleware
This is some very simple middleware that keeps track of the last 3 succesful requests for each visitor. This can be useful if you want to redirect the visitor to a previous path without relying on a hidden field in a form, or if you simply want to check if a visitor has recently visited a certain path. Note that this relies on the session framework and visitors actually accepting cookies. This can be easily modified to hold more requests if you have a need for it.

Choice Field and Select Widget With Optional Optgroups
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.
