CSRF this!
A form with built-in CSRF protection. Include CsrfCookieMiddleware in your MIDDLEWARE_SETTINGS, subclass SafeForm and off you go. See: [this django-developers post](http://groups.google.com/group/django-developers/browse_thread/thread/2c33621003992d07?hl=en) for more info. [edit] This form is actually WAY overengineered currently. Will update soon.

SignedForm: CSRF-protect forms with a hidden token field
This form subclass helps protect against cross-site request forgery by adding a hidden field named `csrf_token` to forms. The form must be initialized with the request as a keyword argument, both with and without POST data: my_form = MySignedForm(request=request) ... my_form = MySignedForm(request.POST, request=request) Upon validation, a `PermissionDenied` exception will be raised if forgery is detected. If any security details have been overlooked in this recipe, please leave a comment.

WorldIP - access to IP database over API
The WorldIP database provides real-world geographical location. Database is more correct than [Whois records and Whois-based databases](http://www.wipmania.com/en/blog/why-worldip-data-rather-than-whois-data-examples/), that show geographic locations of network owners, and not the geographic location of Internet-connected PC or appliance itself.

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')

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.
