auto generate admin.py
When you switch you django project from 0.9.6 to 1.0, you can use this script to generate admin.py automatically. You need copy cvt.py to the parent directory of your project(where your project lies) and type "python cvt.py <project> <app>". The admin.py will generated in the <project>/<app>(where it should be!). Enjoy this small work!

render_partial
Works much like an inclusion_tag but allows the template_name to be given as an argument or defaults to partials/MODELNAME.html where MODELNAME is 'got' from the context object you want to render. Its very rough so improvements very welcome! It would be nice to be able to pass new context variables as template tag [keyword] arguments for use in the template to be rendered so you basically have a template tag equivalent for render_to_string... Example usage in a template: {% render_partial post %} or {% render_partial post partials/super_post.html %}

easy admin registration
This essentially wraps [snippet 917](http://www.djangosnippets.org/snippets/917/) (with full credit to author ncw) in a convenience function so that you can type: admin_register(admin, namespace=globals()) or more concisely: admin_register(admin, globals()) at the end of your admin.py file without having to register each model and admin class individually.

Integer Currency Input
This accepts values such as $1,000,000 and stores them to the database as integers. It also re-renders them to the screen using the django.contrib.humanize.intcomma method which takes 1000000 and turns it into 1,000,000. Useful for large currency fields where the decimals aren't really necessary.

render_with decorator
Automatically render your view using render_to_response with the given template name and context, using RequestContext (if you don't know what this is you probably want to be using it). For example: @render_with('books/ledger/index.html') def ledger_index(request): return { 'accounts': ledger.Account.objects.order_by('number'), }

Moving items up/down from the admin interface
Move Items up and down from the admin interface. Like phpBB does it with its forums. An additional select field is added to the admin form. After the model has been saved, a model method is called (with the value of the new field), which handles the reordering. A more detailed description and a screenshot can be found [here](http://blog.vicox.net/2008/09/04/ordering-in-django-10/).

DebugFooter middleware with textmate links
a minor remix of simon's debug footer: <http://www.djangosnippets.org/snippets/766/> > Adds a hidden footer to the bottom of every text/html page containing a list of SQL queries executed and templates that were loaded (including their full filesystem path to help debug complex template loading scenarios). This version adds TextMate links : if you are working on your local machine and using TextMate you can click on the template paths and they will be opened in TextMate. This speeds up development time considerably ! also, this works with django 1.0 (simon's version got broke by the 'connect' refactor) update: the view function is now linked > To use, drop in to a file called 'debug_middleware.py' on your Python path and add 'debug_middleware.DebugFooter' to your MIDDLEWARE_CLASSES setting.

Remove quotes from bits in a custom tag

Decorator cache handler per view
The @cache_holding decorator works in a per-function base, you can specify a list of models or just a model and the second argument is the time in seconds to be cached. You can modify the proxy class by a keyword argument so you can do cache to all kind of things, also if you want to use a prefix as key + the hash value you can specify the prefix keyword argument.

Improved Accept header middleware
A clean and simple implementation of parsing the Accept header. It places the result in request.accepted_types. Place this middleware anywhere in the chain, as all it does is add to the request object.

Bind Administration
Binds $Model to $ModelAdmin without having to specify each binding manually. The ModelAdmins **must** have the same name as the model (as well as same case) with Admin appended. Example: from django.db import models class SomeModel(models.Model): name = models.CharField(max_length=255) class AnotherModel(models.Model): name = models.CharField(max_length=255) # bind administration bind_administration('myproject.myapp.models', 'myproject.myapp.admin')
