HTTP (basic) auth enabled (new-style) syndication framework feed class

This snipped provides a subclass of the syndication Feed class that supports HTTP authentication (basic auth). Feeds that should support authentication can inherit from this class instead from the Feed class. It is basically the implementation of [Snippet #243](http://djangosnippets.org/snippets/243/) ported to the new-style syndication framework feeds (for which decorators don't work). Usage: class ArticleFeed(HTTPAuthFeed): def items(self, obj): return Article.objects.all().order_by('-created')[:10] def item_title(self, item): return item.title def item_description(self, item): return item.description

Image inlining template tag lib

A custom templatetag for inlining image in the browser. The principe is to base64 encode the image and avoid a http request. There is a cache handling, you just have to specify a writable directory. An example of the utilisation (template part): [http://djangosnippets.org/snippets/2267/](http://djangosnippets.org/snippets/2267/) The explication on [http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/](http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/)

Comparing two json like python objects

Shows difference between two json like python objects. May help to test json response, piston API powered sites... Shows properties, values from first object that are not in the second. Example: import simplejson # or other json serializer first = simplejson.loads('{"first_name": "Poligraph", "last_name": "Sharikov",}') second = simplejson.loads('{"first_name": "Poligraphovich", "pet_name": "Sharik"}') df = Diff(first, second) df.difference is ["path: last_name"] Diff(first, second, vice_versa=True) gives you difference from both objects in the one result. df.difference is ["path: last_name", "path: pet_name"] Diff(first, second, with_values=True) gives you difference of the values strings.

Modify requests in your unit tests (improvement on RequestFactory)

This is an update to Simon Willison's snippet http://djangosnippets.org/snippets/963/, along with one of the comments in that snippet. This class lets you create a Request object that's gone through all the middleware. Suitable for unit testing when you need to modify something on the request directly, or pass in a mock object. (note: see http://labix.org/mocker for details on how to mock requests for testing) Example on how to use: from django.test import TestCase from yourapp import your_view from yourutils import RequestFactory class YourTestClass(TestCase): def setUp(self): pass def tearDown(self): pass # Create your own request, which you can modify, instead of using self.client. def test_your_view(self): # Create your request object rf = RequestFactory() request = rf.get('/your-url-here/') # ... modify the request to your liking ... response = your_view(request) self.assertEqual(response.status_code, 200) Suggestions/improvements are welcome. :)

New view decorator to only cache pages for anonymous users

This is an addition to Django's cache_page decorator. I wanted to cache pages for anonymous users but not cache the same page for logged in users. There's middleware to do this at a site-wide level, and it also gives you the ability to partition anonymous users, but then you have to tell Django which pages not to cache with @never_cache.

RelatedNullFilterSpec: django-admin custom filter all/null/not null/choices

A simple django-admin filter to replace standar RelatedFilterSpec with one with the "All"/"Null"/"Not null" options. It applies to all relational fields (ForeignKey, ManyToManyField). You can put the code in the `__init__.py` or wherever you want. The `_register_front` idea is copied on [this snippet](http://djangosnippets.org/snippets/1963/)
