Django Rest Frameworkでgetを呼び出すと、__init __（）に予期しないキーワード引数 'context'があります

Question

すべてのオブジェクトを取得しようとしているときにエラーが表示されます。

私は私のモデルを書いた：

class Message(models.Model): 
    created = models.DateTimeField(auto_now_add=True) 

    type = models.CharField(_('type'), choices=MESSAGE_TYPE, default='Invitation', max_length=100) 
    content = models.TextField(_('content'), blank=False) 
    sender = models.ForeignKey(User, related_name='sender_message', verbose_name=_("Sender"),) 
    recipient = models.ForeignKey(User, related_name='receiver_message', null=True, blank=True, 
            verbose_name=_("Recipient")) 
    url_profile_image = models.URLField(_('url_profile_image'), max_length=500, blank=True, default='') 

    class Meta: 
     ordering = ('created',) 

マイシリアライザ：

class MessageSerializer(serializers.HyperlinkedIdentityField): 

    class Meta: 
     model = Message 
     fields = ('url', 'id', 'type', 'content', 'Sender', 'Recipient', 'url_profile_image') 

と私の意見：

class MessageViewSet(viewsets.ModelViewSet): 
    queryset = Message.objects.all() 
    serializer_class = MessageSerializer 

を、私は、メッセージのこれらの種類を "作成" することができますよdjango-adminにあります。しかし、私はそれらを手に入れることはできません。

これは全体のエラーです：

あなたのシリアライザは、シリアライザ、あなたがフィールドから継承しているではありません。

class MessageSerializer(serializers.HyperlinkedIdentityField): 

あなたはModelSerializer

class MessageSerializer(serializers.ModelSerializer):
