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.
This allows you to host your own URL shortening service for your site's internal urls. By adding this class as a Mixin to your models, any model with a get_absolute_url method will have a get_short_url method also, which either returns an existing redirect or creates a new one and returns that. **Usage:** Import the class above, add the mixin to your model declaration, and ensure you have declared a get_absolute_url method. `class MyModel = (models.Model, ShortURL):` **Pre-requisites:** You must have the django.contrib.redirects app installed, and you must be using the RedirectFallbackMiddleware as a middleware class. **Settings:** Change the settings in the code above or set them in your settings.py file SHORTURL_CHARS: the characters to use when creating a shorturl SHORTURL_CHAR_NO = the number of characters to use in a shorturl SHORTURL_APPEND_SLASH = whether to append a slash to the end of the shorturl redirect **Notes:** The default settings will give you about 17 million different unique short URLs, reducing the number of characters used to 4 will give you 600,000 or so. That's enough that collisions will be quite rare for sites of a few thousand pages (collisions just result in a urls being generated until an unused combination is found) but if you've got a big site you'll probably want to explore a more robust solution with a proper hash function.

A middleware that restricts staff members access to administration pages.
A function, that converts url into goo.gl link.
Just like `{% spaceless %}`, except a single space is preserved between two inline tags (such as `<a>`, `<em>`, and so on). This lets you use the tag on running text without fear of running two spans of styled text together incorrectly.

Here's an example of writing generic views in an object-oriented style, which allows for very fine-grained customization via subclassing. The snippet includes generic create and update views which are backwards compatible with Django's versions. To use one of these generic views, it should be wrapped in a function that creates a new instance of the view object and calls it: def create_object(request, *args, **kwargs): return CreateObjectView()(request, *args, **kwargs) If an instance of one of these views is placed directly in the URLconf without such a wrapper, it will not be thread-safe.
Sometimes you may want to check how many queries a specific set of operations is taking. This TestCase decorator allows you to do that.
This snippet implements an authentication backend for MoinMoin user accounts. If you have a MoinMoin running on the same server which has users, you can allow those users to sign into a Django site with the same username and password. To use, define the following settings: MOIN_DATA_DIR = "/path/to/moinmoin/data/dir" AUTH_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend', '<this snippet module>.MoinMoinBackend', ) # optional list of groups that authenticating users must be in MOIN_AUTH_GROUPS = ["EditorGroup",]
I was looking for a way to save screen real estate, by using icons instead of labels for my list of choices, which in addition should be displayed as horizontal radio buttons. For example, I wanted to use thumbs_up.gif instead of "approve". I found a HorizontalRadioRenderer here: [https://wikis.utexas.edu/display/~bm6432/Django-Modifying+RadioSelect+Widget+to+have+horizontal+buttons](https://wikis.utexas.edu/display/~bm6432/Django-Modifying+RadioSelect+Widget+to+have+horizontal+buttons) Thanks to Barry McClendon for this snippet! At first, I tried to achieve display of icons instead of labels by modifying the render method, but after a while I gave up on that and decided to just use the choices tuple. This doesn't work too well with a select box (no icons, no text), but in combination with a radio widget it looks quite nice. If you mark the strings for translation, you can also easily change icons, alt and title for each language.
This basically takes the debug you get from setting debug=True, but instead, pipes it into an email and sends it over to you. I have extracted this out of our de framework, it should work, but some modifications may be necessary.
This is some (probably) pretty dodgy code that allows for foreign keys in the admin's list_filter without using a custom FilterSpec. It overrides the django.db.models.options.Options get_field class to handle spanned relationships, i.e. list_filter=('house__room__town',) as seen in http://code.djangoproject.com/ticket/3400 I have only tested this with a double foreign key relationship('house__room'), and it worked. It hasn't been tested in production, and the troubling part of this code is probably to use of 'deepcopy'. I do add those copies back to the options instance, so there shouldn't be too much runaway copying.
I'll throw my implementation into the mix - shortcut for render_to_response as a decorator.
I hate when my unittest hits database. Especially when each test case needs different dataset. So I wrote this db mock, that's local to specific test and uses sqlite3 in-memory db. Usage (nosetests): class TestMainNoData(DbMock): 'testing main function with no meaningful data' def test_no_posts(self): 'there are no posts' assert models.Post.objects.count() == 0, 'should be no feeds'
You can use this code to sign urls for streaming distributions or change it a bit and sign normal distribution's urls. Available settings: CLOUDFRONT_KEY - path to private key file CLOUDFRONT_KEY_PAIR_ID - key pair id CLOUDFRONT_EXPIRES_IN - expiration time in seconds CLOUDFRONT_DOMAIN - domain name
