I was just playing around with Django 1.3 and came across the new 'with' addition to the include tag. I thought this was a super elegant way to implement a DRY tab menu without having to move menu code into the views. Enjoy!
A very plugable way to get Stanislaus jquery dynamic formset working in the admin with adding just one template. Add the following to templates/admin/APP/MODEL/change_form.html and also update the MODEL in the prefix setting. Thanks Stanislaus [http://elo80ka.wordpress.com/2009/10/10/jquery-plugin-django-dynamic-formset/](http://elo80ka.wordpress.com/2009/10/10/jquery-plugin-django-dynamic-formset/) [http://go2.wordpress.com/?id=725X1342&site=elo80ka.wordpress.com&url=http%3A%2F%2Fcode.google.com%2Fp%2Fdjango-dynamic-formset%2F](http://go2.wordpress.com/?id=725X1342&site=elo80ka.wordpress.com&url=http%3A%2F%2Fcode.google.com%2Fp%2Fdjango-dynamic-formset%2F) [http://www.djangosnippets.org/snippets/1389/](http://www.djangosnippets.org/snippets/1389/)
Allows you to hide the filters in the pages of lists of admin. Very useful when filters hide one or more columns. Add this code after the block "extrastyle"
you have a multilingual site and need to change languages in admin. Previously this was easy in the site itself and more difficult in admin. Now it is dead easy. Set up your languages in settings.py. Make a directory called 'admin' in your templates directory, copy ~/django/contrib/admin/templates/base.html to that directory. Add the following code (below breadcrumbs is a good place) this will give you a switcher for all installed languages. You would need to refresh the browser on changing the language.
Based on [this snippet](http://www.djangosnippets.org/snippets/660/), adapted to split a list into *n* number of sublists, e.g. split a list of results into three evenly-divided sublists to enable display of the results in three columns on one page with CSS. Tag: `{% list_to_columns your_list as new_list number_of_columns %}` The split_seq solution comes from a comment by Sebastian Hempel on [this post](http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/425397). More info [here](http://herself.movielady.net/2008/07/16/split-list-to-columns-django-template-tag/).

Sometimes a textarea field is to small for usage. I add some JavaScript and CSS to resize all textareas a little dynamically: The JS change the size in dependence text-lengthen. You should store this snippet into a file like this: templates_django/admin/base_site.html
This is adapted from [rodnsi's version](http://djangosnippets.org/snippets/1818/) to work with Django 1.2 (as django.contrib.admin came with jQuery built in as of 1.2).
The important code really is just setting up the base site to use jquery and then using the javascript function to show the calendar on a widget with the .vDateField class set. The DateField modeltype automatically gets the css class .vDateField when using ModelForms.
See [link](http://www.djangosnippets.org/snippets/2005/) for description. Note: Requires Django 1.2.

Template tag to obfuscate emails and other spam sensitive information. Usage obfuscate '[email protected]' 'Link display' 'Link title' obfuscate '[email protected]' 'Link display' obfuscate 'phone number' Renders complex xhmtl compliant javascript. May need caching as it renders a new code every time.
Couldn't get the original to work, and wanted more functionality (scale on x or y coordinates) <img src="{{ object.image.url }}" alt="original image"> <img src="{{ object.image|thumbnail:"250w" }}" alt="image resized to 250w x (calculated/scaled)h "> <img src="{{ object.image|thumbnail:"250h" }}" alt="image resized to (calculated/scaled)w x 250h h "> <img src="{{ object.image|thumbnail:"250x200" }}" alt="image resized to 250wx200h "> <img src="{{ object.image|thumbnail }}" alt="image resized to default 200w (or whatever you default it to) format"> Original http://www.djangosnippets.org/snippets/192/ Adapted http://www.djangosnippets.org/snippets/955/ Sampled From: http://batiste.dosimple.ch/blog/2007-05-13-1/ http://vaig.be/2008/05/17/stdimagefield-improved-image-field-for-django/
This template extends the change form for the flatpages inside the admin interface to use [Yahoo! User Interface Library](http://developer.yahoo.com/yui/)'s [Rich Text Editor](http://developer.yahoo.com/yui/editor/). It should be named `change_form.html` and be placed in the `admin/flatpages/flatpage/` directory of the project templates.
