username__icontains in django
'''Text based fields have a selection of matching operations.'''
'''For e.g.'''
>>> Author.objects.filter(name__contains='Terry')
[<Author: Terry Gilliam>, <Author: Terry Jones>]
'''
This is not a proper solution sice this requires the user to know
the exact substring of the name.
Here the icontains operation can come in handy and it is a better approach
since it is a case-insensitive match.
