Enable Basic Authetication in your django views. Useful when you have a ajax view accessed by a client that is csrf exempt on HTTP POST

	from django.contrib.auth import authenticate

	'''
	In your views you can call has_basic_auth(request) to check if request headers have a valid Authorization header or not.

	Returns False if header is absent or based on invalid username/password combination.

	Handle the result in your view accordingly

ratpik / patch_tastypie_imagefield.py

Last active December 21, 2015 12:49

A simple way to workaround using HTTP PATCH with Django tastypie on models that contain an Image/File Field

	'''
	I faced a problem when sending a HTTP PATCH to django models containing an ImageField.

	The same problem was discussed on the django-tastypie mailing list - https://groups.google.com/forum/?fromgroups#!topic/django-tastypie/cxrI6Cl1z4s


	When PATCHing a resource, tasypie dehydrates the original object, merges the changed fields, and then simulates a PUT. This presents a problem for FileField and ImageField as dehydrating these fields produces a URL to the file, rather than the path relative to MEDIA_ROOT stored in the database. Therefore, after a PATCH to a model with FileFields, those fields will contain full URLs rather than relatives paths.

	For example, consider a set up in which media for a site is served from http://media.example.com/. When PATCHing a resource containing a file field, a reference to "/directory/file.jpg" will be dehydrated to "http://media.example.com/directory/file.jpg" which is the value that will be written back to the database. - Nikolas Stevenson-Molnar,
