我試圖保存具有引用另一個表的外鍵的模型對象。試圖編寫相同的序列化程序,但無法包裝我的頭如何做到這一點,似乎無法找到正確的文檔。我的模型對象:Django串行器保存具有外鍵關係的模型
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')
我串類RMenuCategory
型號:
class RestaurantMenuSerializer(serializers.ModelSerializer):
restaurant = serializers.PrimaryKeyRelatedField()
class Meta:
model = RMenuCategory
fields = ('id', 'category_name', 'restaurant')
使得API調用使用JSON爲:
{ "category_name" : "Italian", "restaurant_id" : 4}
這不工作時,我嘗試了在我看來:
menu_cat = RestaurantMenuSerializer(data=data)
if menu_cat.is_valid():
category = menu_cat.save()
else:
exit()
