How i can to filter queryset by current user in django rest framework

Question

class SalonCarDetailsSerializer(serializers.ModelSerializer):

    salon = PrimaryKeyRelatedField(queryset=Salon.objects.filter(owner=?))

    class Meta:
        model = SalonCarDetails
        fields = ["salon", "car", "price", "number_of_cars"]

CurrentUserDefault() doesn't works

Answer 1

Well, you could write your own PrimaryKeyRelated field like that:

class SalonKeyRelatedField(serializers.PrimaryKeyRelatedField):
    def get_queryset(self):
        qs = super().get_queryset()
        request = self.context.get('request')
        qs = qs.filter(owner=request.user)
        return qs

This will be called only on POST and PUT requests. You can then include it in your serializer

salon = SalonKeyRelatedField()

don't forget to include salon in your fields
