ModelSerializer default querysets

[bobort]

Some of my ForeignKeys in my models use the limit_choices_to argument. I was a bit surprised to find that the auto-generated forms did not follow the same rules, so I find myself overriding the queryset argument used in my custom ModelSerializer class.

I've never contributed source code to a project, and I really don't know how to do it, but I would like to propose the following replacement to rest_framework/relations.py, line 158:

            if hasattr(self.parent, "Meta") and hasattr(self.parent.Meta, "model"):
                queryset = queryset.filter(
                    **self.parent.Meta.model._meta.get_field(self.source).get_limit_choices_to()
                )
            else:
                queryset = queryset.all()

Truth be told, there's a comment in there about repr output, and my worthless opinion is that you have an incredibly bizarre reason to pass around Managers from the ModelSerializer instead of QuerySets. Isn't there a way to obtain the manager from a QuerySet object so that you can create your own custom repr for them if they're really that important for everyone? But, I digress...

Here's a fixed link to the relevant method.

Okay, we could accept a pull request along those lines, and start by seeing if breaks any of the existing tests or not.
