我正在嘗試顯示我的用戶模型的欄位，但我總是知道我的序列化程式無效 { "non_field_errors": [ "Invalid data. Expected a dictionary, but got User." ] }
這是我的模型
from django.db import models
from django.contrib.auth.models import BaseUserManager, AbstractBaseUser, PermissionsMixin
class UserManager(BaseUserManager):
def _create_user(self, username, password, is_staff, is_superuser, **extra_fields):
user = self.model(
username=username,
is_staff=is_staff,
is_superuser=is_superuser,
**extra_fields
)
user.set_password(password)
user.save(using=self.db)
return user
def create_user(self, username, password=None, **extra_fields):
return self._create_user(username, password, False, False, **extra_fields)
def create_superuser(self, username, password=None, **extra_fields):
return self._create_user(username, password, True, True, **extra_fields)
class User(AbstractBaseUser, PermissionsMixin):
username = models.CharField(max_length=255, unique=True)
email = models.EmailField( max_length=255, blank=True, null=True)
name = models.CharField(max_length=255, blank=True, null=True)
age = models.PositiveIntegerField()
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
objects = UserManager()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = []
def __str__(self):
return f"{self.id} {self.name} {self.username} {self.age}"
這是我的序列化程式
class UserUpdateSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ['id', 'email', 'username', 'name', 'age']
這是我的看法
class UserUpdateApiView(APIView):
def get(self, request, pk):
try:
queryset = User.objects.get(pk=pk)
serializer = UserUpdateSerializer(data=queryset)
if serializer.is_valid(raise_exception=True):
return Response(data=serializer.data)
except User.DoesNotExist:
return Response(data={"error": "User no found"}, status=status.HTTP_404_NOT_FOUND)
uj5u.com熱心網友回復：
您使用了data關鍵字引數，我認為問題就在這里。傳遞不帶關鍵字引數的查詢集：
class UserUpdateApiView(APIView):
def get(self, request, pk):
try:
queryset = User.objects.get(pk=pk)
serializer = UserUpdateSerializer(queryset)
return Response(serializer.data)
except User.DoesNotExist:
return Response(data={"error": "User no found"}, status=status.HTTP_404_NOT_FOUND)
data實際上是序列化的輸出。我相信傳遞輸入模型資料的關鍵字引數是命名實體
