Don't serialize fields from ForeignKey definition

[Stefan72Git]

When i try to serialize fields from ForeignKey definition I receive the following warnings:

serializers.py:312: RemovedInDjango110Warning: 'get_all_related_objects is an unofficial API that has been deprecated. You may be able to replace it with 'get_fields()'
reversed_fields = [obj.field for obj in opts.get_all_related_objects()]

serializers.py:313: RemovedInDjango110Warning: 'get_all_related_many_to_many_objects is an unofficial API that has been deprecated. You may be able to replace it with 'get_fields()'
reversed_fields += [obj.field for obj in opts.get_all_related_many_to_many_objects()]

With Django 1.10 this is a error:
