Easy Form Structuring

With this, you can group form fields very easily. Since it does not create any html, you can use it not only to create fieldsets (with tables, lists, etc).

  • form

Google Analytics Template Tag

Includes the Javascript for Google Analytics. Will not show Google Analytics code when DEBUG is on or to staff users. Use {% googleanalyticsjs %} in your templates. You must set something like GOOGLE_ANALYTICS_CODE = "UA-1234567-1" in your settings file. Assumes 'user' in your template variables is request.user, which it will be if you use: return render_to_response('template.html',{ }, context_instance=RequestContext(request)) (Assuming django.core.context_processors.auth is in TEMPLATE_CONTEXT_PROCESSORS, which it is by default)

Sanitize HTML filter with tag/attribute whitelist and XSS protection

Reworked version of [this snippet](http://www.djangosnippets.org/snippets/205/) that now accepts an argument so the user can specify which tags to allow, and which attributes should be allowed for each tag. Argument should be in form `tag2:attr1:attr2 tag2:attr1 tag3`, where tags are allowed HTML tags, and attrs are the allowed attributes for that tag. It also uses code from [this post on stack overflow](http://stackoverflow.com/questions/16861/sanitising-user-input-using-python) to add XSS protection.

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> `
