I am trying to save a model object that has a foreign key referencing another table. Trying to write the serializer for the same, however can't wrap my head around how to do it and can't seem to find the right documentation either. My model objects:
class Restaurant(models.Model):
name = models.CharField(null=False, max_length=255)
min_order = models.CharField(null=False, max_length=255)
# And so on
class RMenuCategory(models.Model):
category_name = models.CharField(null=False, max_length=255)
restaurant = models.ForeignKey('Restaurant')
My serializer class for RMenuCategory
model:
class RestaurantMenuSerializer(serializers.ModelSerializer):
restaurant = serializers.PrimaryKeyRelatedField()
class Meta:
model = RMenuCategory
fields = ('id', 'category_name', 'restaurant')
Making the api call with the json as:
{ "category_name" : "Italian", "restaurant_id" : 4}
This is not working when I try out the following in my view:
menu_cat = RestaurantMenuSerializer(data=data)
if menu_cat.is_valid():
category = menu_cat.save()
else:
exit()
更改restaurant_id
到restaurant
:
{ "category_name" : "Italian", "restaurant" : 4}
