Cachable Class Method Decorator
This decorator does automatic key generation and simplifies caching. Can be used with any class, not just model subclasses. Also see [Stales Cache Decorator](http://www.djangosnippets.org/snippets/1131/).

Use the primary key in FileField and ImageField filenames
Sometimes it is desirable to use values like the primary key when naming `FileField` and `ImageField` files, but such values are only available after saving the model instance. This abstract class implements a two-phase save in order to make this case easy. See the example in the docstring. Another solution would be to write a `save()` that requires `upload_to` to be a callable that checks for `instance.pk`, then calls it again after saving. However, this would require more work from the developer for simple cases.

Default to current/all sites in admin (updated!)
This code sets the default sites for a sites ManyToMany property to `Site.objects.all()`, which makes sure you don't have to bother setting it for each item on a site. This could easily be changed to `Site.objects.get_current()` to use the current site as default.

Django model cron jobs
Inspired by [snippet 1126](http://www.djangosnippets.org/snippets/1126/), I thought I would post a module that stores crontab entries in a database, with a less powerful, but more end-user friendly API. ("twice a week starting on Sat 1 Dec 2007, 6:23am", instead of "23 6,18 * * *"). The crontab is synchronised when an entry is changed, and relevant environment variables, function name and arguments are provided. You might want to store this as an app called "scheduler" to match the imports. Enjoy!

Allow editing of the selected object of the filter_vertical/filter_horizontal widget with jquery
This patch allows to open a popup to edit the selected object of either the left or right select input of a filter_horizontal or filter_vertical field, when pressing the "Insert" key. Being a noob with general client-side issue, it's served as a patch that suits my needs. Maybe it's possible to do it cleaner by overloading the javascript methods, or get rid of the jquery dependency in order to integrate it into django trunk ... Any contribution is welcome! It's licensed under WTFPL license. Requires jquery.

Gravatar support for Django comments
A templatetag to add [Gravatar](http://www.gravatar.com/) support for [Django comments](http://docs.djangoproject.com/en/dev/ref/contrib/comments/ "Django Comments"). Based on [this snippet](http://www.djangosnippets.org/snippets/772/) but works for everyone who comments even if they are not a registered user.

Get stories by category and some date range
Removed for now... Not sure where to share new Ellington snippets due to the gray-area of it being proprietary. It's an awesome package but it's hard to find any good help with Django 91 code. Good luck ellingtoners!

direct to template from a subdir
I needed a way to quickly get a direction of html pages templated such that another person could drop new templates in to a subdirectory and without modifying urls.py or views.py get them up and being displayed. Now, the direct_to_template view provided django.views.generic.simple can sort of do this with a urlpattern like: `url(r'^(?P<template>.*\.html)$', direct_to_template)` But that means your templates, no matter what level in the url hierarchy they are reached at, have to be defined at the root of a template directory. I wanted them retrieved from a specific subdirectory instead so I could provide a little wall for them. Hence this snippet. To use you would have url pattern that looked like: `url(r'^foo/(?P<template>.*\.html)$', direct_to_template, {'subdir' : 'subdir/'}),` Which will template any url that matches <parent url>/foo/bar.html for any 'bar'. The problem is if this is a sub-url pattern match this is going to look for the template "bar.html" when we may actually want it to get the template "<parent url>/foo/bar.html"

Google Analytics Templatetag
This template tag allows easy inclusion of google analytics script. If Google changes the script in the future, it remains easy to update the template tag with the the new code. This script is tested against Django 1.0 trunk Oct 9 2008. **Readme** After signing up for a Google Analytics account for your domain, define ANALYTICS_ID = "UA-XXXXXXX-X" in your settings.py with the supplied code. Include {% load analytics %} at the top of your base.html and {% analytics %} tag at just before the closing 'body' tag of the base template. Make a template to hold the analytics script. templates/analytics/analytics_html

Prefill ForeignKey caches
Provides an efficient means of looking up multiple related model instances for a range of objects by pre-filling the cache attribute used by `SingleRelatedObjectDescriptor` with either complete model instances or a dict containing only specified fields, looking up all required data with a single query. Example usage: C:\django_projects\soclone>django-admin.py shell >>> from soclone.models import Question >>> from soclone.views import populate_fk_caches >>> from django.db import connection >>> from django.contrib.auth.models import User >>> q = Question.objects.get(id=1) >>> a = list(q.answers.all()) >>> connection.queries = [] >>> populate_fk_caches(User, ( ... ((q,), ('author', 'last_edited_by', 'closed_by')), ... (a, ('author', 'last_edited_by')), ... ), ... fields=('username', 'gravatar', 'reputation', 'gold', 'silver', ... 'bronze')) >>> connection.queries [{'time': '0.000', 'sql': u'SELECT "auth_user"."id", "auth_user"."username", "au th_user"."gravatar", "auth_user"."reputation", "auth_user"."gold", "auth_user"." silver", "auth_user"."bronze" FROM "auth_user" WHERE "auth_user"."id" IN (1, 2)' }]

Twisted protocol for receiving logging module messages over a socket
When using Python's logging module in a concurrent environment (e.g. mod_python), messages get dropped by the standard file-based handlers. The [SocketHandler](http://www.python.org/doc/2.5.2/lib/node414.html) allows you to send logging messages to a remote socket. This snippet provides code for listening for such messages and writing them out to a log file. The final log file is configured as a standard logging file-based handler.

Convert numbers in USA notation to brazilian notation
**This is the converter, just put it as a filter and call it with a float number.** * So, if you have a template variable **{{ my_number }}** that is "3096.44". * It will convert to "3.096,44" using the filter **{{ my_number|numBR }}**.
