Decorator that limits request methods

I wanted to be able to limit which types of requests a view will accept. For instance, if a view only wants to deal with GET requests. @methods(GET) def index(request): # do stuff Now, calling this view with a non-GET request will cause a 403. You can easily change this to a 404, by using a different return function: which you may wish to do with openly available sites, as a 403 indicates there is a resource present.

More information about users and groups in user admin

Based on [this snippet](http://www.djangosnippets.org/snippets/876/). More clean, with links to the related admin forms. Nice example on customization of contributed django admin apps. It adds the following to the user list interface: fields for is_superuser and is_staff, last login time; by default, short names of groups user is in (mousehover to see full names) It adds the following to the to group list interface: list of users in your groups. To enable, just put it somewhere and import it from your main urls.py: import utils/admin_auth.py

Media RSS generation for Photologue

Provides a basic implementation of Yahoo's [MediaRSS](http://video.search.yahoo.com/mrss) format for [Photologue](http://code.google.com/p/django-photologue/) galleries Simplest usage: I have feedgenerator.py in a utils directory. Import photofeeds and hook up the feed url in your URLConf: from utils.feedgenerator import photofeeds urlpatterns += patterns('', url(r'^feeds/(?P<url>.*)/$', 'django.contrib.syndication.views.feed', {'feed_dict': photofeeds}),) Without customization, this will generate a feed for the gallery archive at `/feeds/gallery/` It will contain a single photo per gallery, as returned by Gallery.sample() Additionally, each gallery has a dynamic feed available at the url via Gallery.title_slug: `/feeds/gallery/gallery-title-slug/` This feed will contain an Item for each Photo in the Gallery All that is left is to add an autodiscovery feed to your pages in &lt;head&gt;. An RSS agent like CoolIris can then parse your gallery and provide a slick view of your photos. e.g Add something like this to gallery_detail.html: `<link rel="alternate" href="/feeds/gallery/{{ object.title_slug }}/" type="application/rss+xml" title="Photologue Gallery - {{ object.title }}" id="gallery_feed" /> `

More readable Enumeration class for Django choices

We currently use two-level tuples to specify choices of a field in models or forms. But, because it has only (value, verbose name) pair, the readability is bad whenever we indicate a specific choice value in our Python codes. So I made a small class that does "magic" for this: A Named Enumeration. Instead of `myobj.status == 0`, use `myobj.status == STATUS.UNREVIEWED`, for example.

Template tags to integrate with modconcat

Assumes mod_concat is installed: http://code.google.com/p/modconcat/ Django template tags that combine blocks of CSS and Javascript into modconcat friendly URLs. Takes this: `{% cssconcat "{{ MEDIA_URL }}css/" %} <link href="{{ MEDIA_URL }}css/a.css" rel="stylesheet" type="text/css" /> <link href="{{ MEDIA_URL }}css/b.css" rel="stylesheet" type="text/css" /> <link href="{{ MEDIA_URL }}css/c.css" rel="stylesheet" type="text/css" /> {% endcssconcat %}` And outputs this: `<link href="/site_media/??a.css,b.css,c.css" rel="stylesheet" type="text/css" /> ` Similarly for javascript: `{% jsconcat "{{ MEDIA_URL }}js/" %} <script src="{{ MEDIA_URL }}js/a.js" type="text/javascript"></script> <script src="{{ MEDIA_URL }}js/b.js" type="text/javascript"></script> <script src="{{ MEDIA_URL }}js/c.js" type="text/javascript"></script> {% endjsconcat %}` becomes: `<script src="/site_media/??a.js,b.js,c.js" type="text/javascript"></script> `

Show users' full names for foreign keys in admin

This is a ModelAdmin base class you can use to make foreign key references to User a bit nicer in admin. In addition to showing a user's username, it also shows their full name too (if they have one and it differs from the username). **2009-08-14**: updated to handle many to many fields and easily configure whether to always show the username (if it differs from full name)

Template class to test custom tag libraries

TestableTemplate behaves just like django.template.Template, but you can give it a list of template.Libraries to load before parsing the template. This is equivalent to adding a bunch of {% load %} tags to the beginning of your template string, but you can use custom tag libraries which do not belong to Django applications' templatetags packages. This is occasionally useful in testing.
