Как я могу переопределить метод create в сериализаторе с несколькими вложенными полями в django?

Question

Я пытаюсь создать записываемый вложенный сериализатор. Я читал Джанго документов отдыха, но в моем случае у меня есть несколько вложенных полей и не знает, как можно решить, что я получаю эту ошибку:

TypeError в/API/v1/библиотеках/ «tel_number» является недопустимым ключевым словом аргумент для этой функции

models.py:

    picture  = models.BooleanField(default=False) 
    passport  = models.BooleanField(default=False)

class SpecificInformatin(models.Model): 
    specific_name = models.CharField(max_length=255) 
    description = models.TextField(max_length=255) 

    def __unicode__(self): 
     return self.specific_name

    district = models.CharField(max_length=2)

Вы делаете какой-то м istake. когда вы выталкиваете некоторые данные из dict, они возвращают значение конкретных данных.

create(self, validated_data): 
 
     address_data = validated_data.pop('address') 
 
     address = Address.objects.create(**address_data) 
 

 
     register_rules_data = validated_data.pop('register_rules') 
 

 
     specific_information_data = validated_data.pop('specific_information') 
 

 
     library = Library.objects.create(address=address, **validated_data) 
 

 
     for data in register_rules_data: 
 
      register_rules = RegisterRule.objects.create(**data) 
 
      library.register_rules.add(register_rules) 
 
     for data in specific_information_data: 
 
      specific_information = SpecificInformatin.objects.create(**data) 
 
      library.specific_information.add(specific_information) 
 

 
     return library

Я думаю, что этот код будет работать для вас.
