Specify Django REST Framework version in requeriments

[melizeche]

DRF is a library in constant development and every version have changes and deprecations in the API, right now with the last current version(3.5.4) from pipy I'm getting a lot of errors like
AssertionError: ("Creating a ModelSerializer without either the 'fields' attribute or the 'exclude' attribute has been deprecated since 3.3.0, and is now disallowed. Add an explicit fields = '__all__' to the ItemSerializer serializer.",)
Maybe it's DRF, maybe it's other thing but I think the DRF version need to be set to one that we can be sure works with the project.
Thanks

I concur. I will look into this when I have the time.

@melizeche : if you add fields = '__all__' to class Meta: of those ModelSerializer then you don't get this error
