django RestFrameWork _OneToOneField序列化器.create（）FOREIGN KEY约束失败

Question

我的django项目中有两个模型。 AdIfo和AdGame。 Adgame模型与Adjfo.in django管理面板具有OneToOne关系。我可以构建正确的Object AdGame模型。但是，当我尝试在序列化程序中进行操作时，错误是：IntegrityError

 FOREIGN KEY constraint failed

Models.py：

class AdIfo(models.Model):
    address = models.TextField(max_length=250)
    price = MoneyField(max_digits=12, decimal_places=0, 
           default_currency="IRR")
    phonenumber = models.CharField(validators=[phone_regex], 
           max_length=17, null=True, blank=True)
           ad_status = models.BooleanField()



class AdGame(models.Model):
    CONSOLE_GAME = (
        ('XBX', 'Xbox'),
        ('PS4', 'Play Station 4'),
        ('PC', 'Personal Computer'),
         )
    GAME_REGION = (
        ('1', 'USA'),
        ('2', 'Europe'),
        ('3', 'MiddleEast'),
        ('j', 'Japan'),
        ('4', 'Australia'),
        ('N', 'Unknown')
        )
    title = models.CharField(max_length=25)
    game = models.ForeignKey(Game, on_delete=models.CASCADE)
    console = models.CharField(max_length=3, choices=CONSOLE_GAME)
    game_region = models.CharField(max_length=1, choices=GAME_REGION)
    ad_info = models.OneToOneField(AdIfo, related_name='ad_info', 
          primary_key=True, on_delete=models.CASCADE)
          description = models.TextField(max_length=500, blank=True)
    owner = models.ForeignKey(User, related_name='ad_owner', 
          on_delete=models.CASCADE)
    image = StdImageField(upload_to=UploadToClassNameDirUUID(), 
          blank=True, variations={
          'large': (800, 600),
          'medium': (600, 400),
          'small': (300, 200),
          'thumbnail': (100, 100, True),
           })
          publish_date = models.DateTimeField(auto_now=True)

    def __str__(self):
       return self.title

我知道我的问题是在django rest框架中你必须处理create()。必须首先创建模型AdIfo，然后创建AdGame.I尝试将Adgame的AdIame ID作为kwargs传递，但我的知识还不够。我意识到AdIfo没有将adInfoSerializer中的id传递给AdGameSerilizer。但是我做了测试AdInfoSerializer的视图。一切都很好，id字段将包含在我的结果中。
