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/).

Model dependency graph using graphviz (script)
Instructions: Set your environment variables, install graphviz, and run. Finds all models in your installed apps and makes a handsome graph of your their dependencies based on foreignkey relationships. Django models have green outlines, yours have purple. The edge styling could be changed based on edge type.

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'), }

Something like list_detail generic view but returns PDF document instead
This should work as a `django.views.generic.list_detail` generic view but will produce PDF version of given template. This code is merged code from perenzo's [example](http://www.djangosnippets.org/snippets/659/) and code from `django.views.generic.list_detail` module. `pisa` package is required from (http://www.htmltopdf.org/download.html) with `html5lib` package and Reportlab Toolkit 2.1+ NOTE: this is code for Django 0.96. In Django 1.0 change in line 3: ObjectPaginator to Paginator

Form splitting/Fieldset templatetag
Syntax: `{% get_fieldset list,of,fields as new_form_object from original_form %}` Example: {% load fieldsets %} ... <fieldset id="contact_details"> <legend>Contact details</legend> <ul> {% get_fieldset first_name,last_name,email,cell_phone as personal_fields from form %} {{ personal_fields.as_ul }} </ul> </fieldset> <fieldset> <legend>Address details</legend> <ul> {% get_fieldset street_address,post_code,city as address_fields from form %} {{ address_fields.as_ul }} </ul> </fieldset>

Timestamps in Model
A simple way to add `date_created` and `date_modified` timestamps to a model. Adds a `date_created` timestamp when the object is first created and adds a `date_modified` timestamp whenever the item is saved. **Note:** You might be tempted instead to use: `date_created=models.DateTimeField(default=datetime.now())` but that won't work as Python will calculate `datetime.now()` only once when it interprets your model. This means that every object created will get the same `date_created` timestamp until you restart your server.

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.

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 %}

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!

TestSettingsManager: temporarily change settings for tests
This TestSettingsManager class takes some of the pain out of making temporary changes to settings for the purposes of a unittest or doctest. It will keep track of the original settings and let you easily revert them back when you're done. It also handles re-syncing the DB if you modify INSTALLED_APPS, which is especially handy if you have some test-only models in tests/models.py. This makes it easy to dynamically get those models synced to the DB before running your tests. Sample doctest usage, for testing an app called "app_under_test," that has a tests/ sub-module containing a urls.py for testing URLs, a models.py with some testing models, and a templates/ directory with test templates: >>> from test_utils import TestManager; mgr = TestManager() >>> import os >>> mgr.set(INSTALLED_APPS=('django.contrib.contenttypes', ... 'django.contrib.sessions', ... 'django.contrib.auth', ... 'app_under_test', ... 'app_under_test.tests'), ... ROOT_URLCONF='app_under_test.tests.urls', ... TEMPLATE_DIRS=(os.path.join(os.path.dirname(__file__), ... 'templates'),)) ...do your doctests... >>> mgr.revert()
