Question

我正在尝试使用OneToOneField扩展User模型，因此我可以向用户添加更多字段：

class Userattribs(models.Model):    
    user = models.OneToOneField(User)
    passcode = models.IntegerField(default=0)

    # about user
    organisation = models.CharField(max_length=100, null=True)
    description = models.CharField(max_length=300, null=True)

我还有以下型号序列化器：

class UserattribsSerializer(serializers.ModelSerializer):   
    class Meta:
        model = Userattribs

        fields = ('organisation', 'description')

class UserSerializer(serializers.ModelSerializer):
    userattribs = UserattribsSerializer(required=True)

    class Meta:
        model = User

        fields =('id', 'username', 'first_name', 'last_name', 'email', 'userattribs')

我遇到的问题是用户序列化，不包括json响应中的'userattribs'。我花了几个小时谷歌搜索和敲打我的头。如果你帮助我，我将永远感激。

提前致谢！

我添加了观点。我注意到的一件奇怪的事情是当我查询（使用UserList）所有数据时，我会得到Userattribs。但是，当我检索单个项目时，我没有得到Userattribs

class UserList(generics.ListCreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    permission_classes = (permissions.AllowAny,)

class UserDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    permission_classes = (access_permission,)

我的代码中没有任何错误。您确定User个对象有Userattribs个对象。

使用python manage.py shell打开你的python shell并输入它来测试你的代码：

#import your related models and serializer
from your_app.models import *
from your_app.serializer import *
# create new user
user = User.objects.create(username="test")
# create new user attrib linked to `user` object
user_attrib = Userattribs.objects.create(user=user, organisation="DJANGO")
# serialize your `user` object
user_serializer = UserSerializer(user)
# display your serialized data
user_serializer.data
# outputs : {'last_name': '', 'userattribs': OrderedDict([('organisation', 'DJANGO'), ('description', None)]), 'email': '', 'username': 'test', 'first_name': '', 'id': 3}

如果没问题，可能会出现问题。
