我在尝试获取所有对象时遇到该错误。
我这样写我的模型:
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',)
我的序列化器:
class MessageSerializer(serializers.HyperlinkedIdentityField):
class Meta:
model = Message
fields = ('url', 'id', 'type', 'content', 'Sender', 'Recipient', 'url_profile_image')
和我的观点:
class MessageViewSet(viewsets.ModelViewSet):
queryset = Message.objects.all()
serializer_class = MessageSerializer
我能够在 django-admin 中“创建”那些类型的消息。但是我无法得到它们，在创建它们时会出现端点。
这是整个错误:

请您参考如下方法:
您的序列化程序不是序列化程序，您是从字段继承的。
class MessageSerializer(serializers.HyperlinkedIdentityField):
你应该使用一个ModelSerializer
class MessageSerializer(serializers.ModelSerializer):
