使用Django Rest Framework API删除相关模型

Question

当我使用Django Rest Framework删除用户时，关联的UserProfile对象也被删除。我想反向关系也是如此。我怎样才能做到这一点？

我有一个代表用户个人资料的Django模型。

class UserProfile(models.Model): 
    user = models.OneToOneField(User, related_name='profile') 
    preferred_name = models.CharField(max_lengths=100) 
    #other fields here 

这里是我的看法：

class UserDetail(generics.RetrieveUpdateDestroyAPIView): 
    """ 
    API endpoint that represents a single user. 
    """ 
    model = User 
    serializer_class = UserSerializer 

class UserProfileDetail(generics.RetrieveUpdateDestroyAPIView): 
    """ 
    API endpoint that represents a single UserProfile 
    """ 
    model = UserProfile 
    serializer_class = UserProfileSerializer 

而串行：

class UserSerializer(serializers.HyperlinkedModelSerializer): 
    profile = serializers.HyperlinkedRelatedField(view_name = 'userprofile-detail') 

    class Meta: 
     model = User 
     fields = ('url', 'username', 'email', 'profile') 

class UserProfileSerializer(serializers.HyperlinkedModelSerializer): 

    class Meta: 
     model = UserProfile 
     fields = ('url', 'preferred_name', 'user')

你可以在你的用户配置类覆盖删除的方法，这样的：

class UserProfile(models.Model): 
    user = models.OneToOneField(User, related_name='profile') 
    preferred_name = models.CharField(max_lengths=100) 
    #other fields here 
    def delete(self, *args, **kwargs): 
     self.user.delete() 
     super(UserProfile, self).delete(*args, **kwargs)
