"Dynamic" form with a hidden field

This code demonstrates two simple techniques: 1. so-called "dynamic" forms, in which the form is created at run time by the model 2. using a widget (forms.widgets.HiddenInput) for a field of the form. I feel like this could be highlighted more in the documentation. You need to do something similar to get a textarea (forms.CharField(widget=forms.widgets.Textarea()) and it took me too long to figure this out. There are, no doubt, good reasons not to do what I'm doing here the way I'm doing it. Peanut gallery?

RequiredNullBooleanField

In our situation, we want the user to choose either yes or no. The only requirement is that they fill out the form. It is _not_ required that they answer True/Yes. The BooleanField treats None and False as False; The NullBooleanField distinguishes between None and False, but it doesn't raise any validation errors. Subclassing the NullBooleanField was better than overriding the clean method on all of our NullBooleanField instances.

Custom Admin Redirects

This little bit of code will let you reference parts of the admin but lets you control where it returns to. For instance, I have a list of objects in the admin and i want to have a delete link for each object. I don't want them to return to the changelist after a delete however, i want them to return to my list. cheers

Filter to adjust forloop.counter across pages in a paginated view

**Update:** Never mind. See [dc's comment](http://www.djangosnippets.org/snippets/1391/#c1763) below for a much easier way to do this. I recently had to write a template for a paginated view which displayed a serial number for each `object` in the `object_list`. I normally use `forloop.counter` for general purpose serial numbers. However this did not work with paginated views as the counter gets reset in each page. This caused the serial numbers to go from 1 to #-of-results-in-the-page and then repeat. **Assumptions:** The `adjust_for_pagination` filter adjusts the value of `forloop.counter` based on the current page. `Page` and `is_paginated` variables are expected to be present in the context. These should respectively denote the current page number (1 based) and if the results are paginated. `RESULTS_PER_PAGE` is currently taken from the settings file. I couldn't think of a way to pass this value also from the template.

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.

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/).

Globs for INTERNAL_IPS

Allows you to include globs of IP addresses in your INTERNAL_IPS. It's shell-style glob syntax (the [fnmatch module](http://docs.python.org/library/fnmatch.html)). This should be helpful with the [Debug Toolbar](http://github.com/robhudson/django-debug-toolbar/tree/master), among other things. Like [#1362](http://www.djangosnippets.org/snippets/1362/), but with no external dependencies.

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.
