ModelForm Class saving m2m
**Your model:** class TicketItem(models.Model): hours = models.DecimalField(decimal_places=2, max_digits=6) day = models.DateField() order = models.ForeignKey(Order) tickets = models.ManyToManyField(Ticket) Now you want to auto save m2m fields in your forms.TicketItemCreateForm: 1. inherit from m2mForm-Class 2. define m2m_field(s) **Example:** class TicketItemCreateForm(m2mForm): m2m_field = 'tickets' class Meta: model = models.TicketItem

Automatically read the ID3 tag from a mp3 on save
This code allows you to upload a mp3 to the Admin Frontend. The ID3 tags are automatically read out and filled in to the according fields. This should work for other filetypes as well. As long as they have an id3 tag.

Password Validation - Require Letters and Numbers - no regex
Simple password validation for user registration - requires that password be 7 or more characters and contain both letters and numbers. Original validation with regex approach developed by kurtis. Optimized no-regex version based on code from watchedman ran as fast or significantly faster on all systems on which we tested it.

Admin log entries management utils
A collection of utilities for admin log entries management. This module provides functions to add log entries for instance addition, change and deletion, as seen in *django.contrib.admin.options*. It also provides a class based view mixin to add logging capabilities, and other tools as a log collector. See docstrings for a better description.

Manual CSRF check for Django Facebook canvas applications
The way to manually control CSRF correctness for FB applications. Automatic check cannot be used because FB does POST on your canvas URL when initializing your application without CSRF token. If you still want to use Django CSRF stuff do manual checks. You only need to perform manual check when there is no correct signed_request present in your request - correct request means you really deal with FB. Use facebook_csrf_check to verify POST requests when signed_request is absent.

Decorating URL includes
Apply a decorator to every urlpattern and URLconf module returned by Django's include() method . This allows you use a decorator on any number of views without having to decorate each one individually. The use case here is wrapping all of the Django Admin with a superuser decorator. This is code that's better left alone where we can't actually go in and decorate the Admin views and urlpatterns manually. It's also almost guaranteed the Admin will include() other URL files. So the added bonus is all the INSTALLED_APPS that have their admin.py files registered by admin.autodiscover() will be decorated automatically as well. This snippet is greatly inspired by [@miracle2k](http://djangosnippets.org/users/miracle2k/)'s excellent [#532](http://djangosnippets.org/snippets/532/). In the comments there @timbroder offers a modification to decorate includes but I think this is cleaner, simpler code and not subject to changes in the Django base code driving _get_url_patterns().

ByteSplitterField
When you want to save integers to the db, you usually have the choice between 16-, 32- and 64-bit Integers (also 8- and 24-bit for MySQL). If that doesn't fit your needs and you want to use your db-memory more efficient, this field might be handy to you. Imagine you have 3 numbers, but need only 10 bit to encode each (i.e. from 0 to 1000). Instead of creating 3 smallint-fields (48 bit), you can create one 'ByteSplitterField' which implements 3 'subfields' and automatically encodes them inside a 32 bit integer. You don't have to take care how each 10-bit chunk is encoded into the 32-bit integer, it's all handled by the field (see also field's description). Additionally, the Field offers opportunity to use decimal_places for each of your subfields. These are 'binary decimal places', meaning the integer-content is automatically divided by 2, 4, 8, etc. when you fetch the value from the field. You can also specify how values are rounded ('round' parameter) and what happens when you try to save a value out of range ('overflow' parameter) Not implemented (maybe in the future if I should need it sometime): * signed values. All values are positive right now! * real (10-based) decimal places (actually you could probably directly use DecimalFields here) * further space optimization, i.e. saving into CharField that's length can be chosen byte-wise

ultralize
This is a function based on django's urlize modified to show different media based on their url. It supports images, links, mp3/ogg links, youtube videos, vimeo videos and dailymotion videos. I added a switch called mini to have two modes to show things in different places. When mini is activated it will only parse the first url provided and discard the rest as well as limiting the height.

Dynamically insert or append a value to an admin option, e.g. list_display or list_filter
You can use this function to change an admin option dynamically. For example, you can add a custom callable to *list_display* based on request, or if the current user has required permissions, as in the example below: class MyAdmin(admin.ModelAdmin): list_display = ('__unicode__', 'other_field') def changelist_view(self, request, extra_context=None): if request.user.is_superuser: add_dynamic_value(self, 'list_display', my_custom_callable) return super(MyAdmin, self).changelist_view(request, extra_context)

Load File From URL Widget
Rather simple usage, modelforms/in the admin: class CustomAdminForm(forms.ModelForm): class Meta: model = Something widgets = { 'image': URLFileInput(default_exts=[".png", ".gif", ".jpg"]), } class SomethingAdmin(admin.ModelAdmin): form = CustomAdminForm admin.site.register(Something, SomethingAdmin) Basically, this will pull the image from the URL instead of only pulling it from your harddrive for upload. Also accepts optional default_exts argument which limits the file types. Defaults to images.
