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.

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.

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

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.

Create multiple related objects at once
The following code takes two related models and creates one user interface to for create and update operations that handles them both. It enables the creation or update of instances from both models in one shot, without having to create very complex forms. As I could not find examples for creation of related objects together, I thought this might be useful for someone.

streaming dump_data
`dumpdata` without `MemoryErrors`, with progress notification. Most of the real work is done by snippets [1400](http://www.djangosnippets.org/snippets/1400/) and [1401](http://www.djangosnippets.org/snippets/1401/). ./manage.py dumpdata_stream --format=xml > big_dump.xml This is basically the stock Django `dumpdata` with a few modifications. Django devs: it's hard to reuse parts of most Django management commands. A little refactoring could go a long way.

Language aware template loader
If you try to load a template named filename.LANG.html it will try to load filename.de.html first, then filename.html afterwards (assuming that German is the currently selected language). Usage: Put in a file named langtemplateloader.py under your project, and replace django's default filesystem loader with this in the TEMPLATE_LOADERS section of settings.py: TEMPLATE_LOADERS = ( 'myproject.langtemplateloader.load_template_source', # 'django.template.loaders.filesystem.load_template_source', 'django.template.loaders.app_directories.load_template_source', 'django.template.loaders.eggs.load_template_source', )
