ResourceRelatedField now accepts serializer methods which return querysets.

[sonthonaxrk]

Specifying the source of a field to be a method on a serializer, only works if many=False. This pull request allows you to use serializer methods for ResourceRelatedField which return multiple objects.

Which allows you to do things like this:

class EntrySerializer(serializers.ModelSerializer):
    included_serializers = {
        'approved_comments': 'example.serializers.EntrySerializer',
    }
    approved_comments = relations.ResourceRelatedField(source='get_approved_comments',
            many=True, model=Comment, read_only=True)

    def get_approved_comments(self, obj):
        return self.comments.approved()

If the original author is fine with it, I'd like to take over this PR.

@jerel, which part of the PR are you referencing in this comment?

The way our ResourceRelatedField was implemented before wasn't ideal (source was ambiguous between serializer and model) so this functionality has been moved to the more explicitly named SerializerMethodResourceRelatedField since you opened this PR.

Thanks!

@cpa the functionality should ideally be moved into SerializerMethodResourceRelatedField with many=True instead of adding ManyResourceRelatedField like this PR does.
