Limit choices to foreignkey in django rest framework

Question

How to limit images of request.user to be linked with node. I wish I could do something like:

photo = models.ForeignKey(
    Image,
    limit_choices_to={\'owner         


        

Answer 1

I would deal with this by overriding get_serializer_class to dynamically return a serializer class at runtime, setting the choices option on the field there:

def get_serializer_class(self, ...):
    user = self.request.user
    owner_choices = ...  # However you want to restrict the choices

    class ImageSerializer(serializers.ModelSerializer):
        owner = serializers.Field('owner.username', choices=owner_choices)

        class Meta:
            model = Image
            fields = ('file', 'owner')

    return ImageSerializer
