Unittest: Compare max_size with column size of database
Changing the size of max_length in the model is fast. But sometimes you forget to update all running systems which use this model. This unittest helps you to find the difference between Model and DB before the users get uncaught exceptions.

Add ValidationError to a field instead of __all__ during Form.clean()
If you need two values for validation, you can't use clean_value_a() since it is undefined if value_a or value_b gets cleaned first. This little helper lets you add ValidationErrors to fields instead of \__all\__. Related [Ticket 5335](http://code.djangoproject.com/ticket/5335).

urlquote() and urlencode() in one method
I think this method is handy, since you don't need to remember if you need urlquote or urlencode. It does both and adds a question mark between the path and the get parameters, if later are present. And it works around a bug in Django: MultiValueDicts (request.GET, request.POST) are handled correctly. Related: [http://code.djangoproject.com/ticket/9089](http://code.djangoproject.com/ticket/9089)
