monkey-patch django to use jinja2 templates for 404/500 pages and 3rd-party apps
This is heavily inspired by [http://code.google.com/p/smorgasbord/](http://code.google.com/p/smorgasbord/). But that couldn't reuse an existing jinja2 Environment, nor set filters on the Environment it created. This code assumes that you have `env` declared previously in the file as your Jinja2 Environment instance. In `settings.py`, you should set KEEP_DJANGO_TEMPLATES = ( '/django/contrib/', ) so that your Django admin still works. You can also set any other places that you do want to use Django templates there.

Significant digits filter
Formats float values with specified number of significant digits (defaults to 3). Usage: `{{value|sigdig}} # with 3 significant digits by default` `{{value|sigdig:digits}}` Examples: `{{0.001432143|sigdig}}` renders as `0.00143` `{{874321.4327184|sigdig}}` renders as `874000` `{{874321.4327184|sigdig:5}}` renders as `874320` Useful for scientific or engineering presentation.

ChoiceField with widget in choice
This code creates a widget that we used to generate a list of radiobuttons as follows: * Radio button 1 --Widget__1 * Radio button 2 --Widget__2 * Radio button 3 --Widget__3 How to use it is: `ImagenForm class (forms.ModelForm): widget1 = forms.BooleanField () widget2 = forms.TextInput widget3 = forms.ModelChoiceField (queryset = Modelo.objects.all ()) widget4 = forms.FileInput optConListas = ChoiceWithOtherField (choices = [(2, 'widget1' widget1), (3, 'widget2' widget3.widget), (4, "widget2" widget2), (5, 'widget4' widget4)])`

iPhone Redirect Middleware
I didn't really like the current state of iPhone/Mobile redirect middleware mainly because I wanted something that was closer to twitters use case. So I came up with this. I don't think it a great snippet and I will probably fix it in the near future. But it works.

Paginator Tag for 1.x
This is a [Paginator Tag](http://www.djangosnippets.org/snippets/73/) for 1.x. Since the context is less overfull, the template, paginator.html, needs more logic. Put the tag in your templatetags and the template at the root of a template-directory. The tag will work out of the box in a generic view, other views must provide `is_paginated` set to True, `page_obj`, and `paginator`. You can get the `object_list` from the `page_obj`: `page_obj.object_list`. See [the pagination documentation](http://docs.djangoproject.com/en/1.0/topics/pagination/).

django-noserun for testing
I wanted to use Nose with Django so I came up with this. `TEST_RUNNER = 'noserun.run_tests'` in settings.py It does not do setup/teardown implicitly between test methods, you need to call *nosetest.test.flush()* and *nosetest.test.loaddata()* manually if you want that. Enables the method names *setup* and *teardown* The environment variable *NOSE_COVER* runs coverage tests and *NO_DROPDB* preserves the test db.
