Get the full request path
The result maybe: http://localhost/test/ And for request.path, it will not include the domain field(http://localhost).

Parsing and Highlighting <code> Blocks
This function takes a string (most likely from a template), searches it for `<code>[...]</code>`, highlights it with Pygments, and returns the entire thing back, as a string. (Note: the `<code>[...]</code>` must have a class corresponding to the language inside. If it lacks the class, then it's silently ignored.)

- beautifulsoup
getattr template filter
Put inside `mysite/templatetags/getattr.py` Add `mysite` to your `INSTALLED_APPS` In your template: {% load getattr %} {{ myobject|getattr:"theattr,default value" }} Thanks to pterk for optimizations! \\o/

Converting a Flickr Datetime to a Python Datetime
Though this may not be Django (just basic Python) this kind of thing sure does come in handy! __Plus, it's super easy to edit for any datetime format you want to throw at it.__

Using Pygments with reST
UPDATED: This now supports an argument for the initial header level. This is a modified version of `django.contrib.markup` that allows you to highlight code via [pygments](http://pygments.pocoo.org/). The code block can be used as: `Here's a paragraph, and a code example: .. code:: language *insert code here* continue with your normal document.` Setup: Insert the snippet into `mysite/templatetags/rest.py`, then add `mysite` to your installed apps in `settings.py`. In your template, `{% load rest %}` and `{{ mycontent|rest }}`.

Using Textarea
A very common field in forms is the `<textarea>`, but `newforms` has no such field. Instead, you must use a dummy field (such as `newforms.CharField`) and use the `newforms.widgets.Textarea()` widget to render a textarea.

Line & paragraph chopping
I was faced with the fact that I wanted to post 2 paragraph-long summaries on one of my sites, and this is what I did (you could of course cut it down earlier, but I'd say this belongs to what is called "template logic") Use like so: {% load myExtraModule %} {{ blogpost.content|paragraphs:"2" }} The lines filter works the exact same way, and you might want to improve on these a bit, I don't maintain them as I don't use them anymore.

Serving null files
Sometimes you have to serve null files. This quick hacky generic view lets you do that. The best example of that is robots.txt, I want my robots.txt to always be empty, at least for now. The other example would be favicon.ico, but that's more often used to actually fill a purpose.

Updated version of #31
This is, I think, a slightly cleaner implentation of what [snippet 31](/snippets/31/) is trying to do; by starting off with a dictionary containing the things we want to look for, and using a list comprehension to kill anything which comes out of the form as `None`, we can avoid some of the intermediate data structures the other snippet was using, and hopefully get better performance. This is also quite a bit more maintainable, because supporting additional options now only requires adding a new key/value pair to `qdict`.

Search in a model spanning relations
By popular demand an example of search in models that spans more realtions. Keep a list of Q, filter the None away, feed the rest to .filter() Credit goes to Carlo C8E Miron for the idea... cheers buddy! ;)

Contact Form
A simple way to get started using newforms. Implement a contact form. Mine saves the data in a table and sends a dedicated mailbox the feedback as well. I added support for TinyMCE as described in the django wiki. http://code.djangoproject.com/wiki/CustomWidgetsTinyMCE?format=txt Anyway use this as a starting point for writing your own form handling.

slugify js -> python
This code is derived from the slugify JS function used in django's admin interface. It will create django-compatible slugs for you. Sometimes I do batch imports and need my items to have slugs, I give this script the item's title and get a slug back. Simple

Mini issue tracker
Described more fully on [my blog](http://e-scribe.com/news/230), but the gist is: this model becomes a sort of mini-app in your admin, allowing you to record and track issues related to your other applications. Sorting still needs some work. UPDATED 2007-03-14: Fixed repeat in Admin.list_display (thanks, burly!); added Admin.list_filter; changed app list (why did I call that `PROJECTS`, anyway?) to omit "django.*" apps

assign fields dynamically in newforms
DynamicFieldSnippetForm demonstrates how to dynamically assign fields in newforms. 1. weight is a required static field 2. height is an optional dynamic field This example uses `request_height` as an optional keyword argument to declare whether the `height` field should be added to the form, but it's just there for demonstration purposes. If you decide to use a keyword argument in your code, be sure to pop it off (as demonstrated in the code) or you'll get an *unexpected keyword argument* error.
