This is caching mechanism augmented to help address a number of common pitfalls in caching: cache stampeding, simultaneous expiry, cache invalidation, and the storing of None as a legitimate value. No doubt the automatic key generation could stand to be simplified, but it works.
Sometimes using regex is a huge pain
This displays the short commit id from the current HEAD. Add this to your admin/base_site.html or any other template. {% block userlinks %} / HEAD: <span style="color:yellow">{% git_short_version %}</span> / {{ block.super }} {% endblock %}
With this function if you filter using regular admin filters you'll reduce the queryset to the objects in view.
Routes models of each app into the database with same name falling back to "default" database.
Simple tag to check which page we are on, based on resolve: useful to add an 'active' css class in menu items that needs to be aware when they are selected. Typical usage is like: ` <ul> <li class="{% active request "myapp:myview1" %}">My View 1</li> <li class="{% active request "myapp:myview2" %}">My View 2</li> </ul> `
Based on the original http://code.google.com/p/django-thumbs/ Added South support too. Usage: ` photo = ImageWithThumbsField(upload_to='images', sizes=((125,125,True),(300,200),)` To retrieve image URL, exactly the same way as with ImageField: `my_object.photo.url` To retrieve thumbnails URL's just add the size to it: `my_object.photo.url_125x125` `my_object.photo.url_300x200` To convert to greyscale set the third attribute of size to True
This method will return an inline formset class that validates values across the given field are unique among all forms. For instance: ApprovedUserFormSet = inlineformset_factory(Request, ApprovedUser, formset=unique_field_formset('email'), form=ApprovedUserForm) Will make sure all ApprovedUser objects created for the Request have unique "email" fields.
There is a lot of debate on whether there is a real future for the Django CBVs (class based views). Personally, I find them tedious, and just wanted a way to keep my views clean. So, here is a really minimalistic way of having class based views, without the fuss. This is a fork from: http://stackoverflow.com/questions/742/class-views-in-django http://djangosnippets.org/snippets/2041/
This is hardcoded to use [django-discover-runner](http://pypi.python.org/pypi/django-discover-runner) since that's my main test runner but could easily be adopted to use Django's own test runner. If you're using a terminal that is capable of showing 256 colors use the `Terminal256Formatter` formatter instead. Enabled it with the `TEST_RUNNER` setting: TEST_RUNNER = 'dotted.path.to.highlighted.runner.HighlightedDiscoverRunner' Where `dotted.path.to.highlighted.runner` is the Python import path of the file you saved the runner in.
