KeyError at /api/login 'user'

Question

这个用户关键字错误显示在我的登录api中。我不知道为什么。我猜用户实例在登录视图中不可用。我是新来的，我不知道原因。

这是我的登录视图：

class LoginUserView(GenericAPIView):
permission_classes = [AllowAny]
serializer_class = UserLoginSerializer
def post(self, request, *args, **kwargs):
data = request.data
serializer = UserLoginSerializer(data=data)
serializer.is_valid(raise_exception=True)
user = serializer.validated_data["user"]
token, created = Token.objects.get_or_create(user=user)
return response.Response({"token": token.key}, status=status.HTTP_200_OK)

这是我的序列化程序：

class UserLoginSerializer(serializers.ModelSerializer):
email = serializers.EmailField(label='Email Address')
class Meta:
model = User
fields = [
'email', 'password',
]
extra_kwargs = {"password":
{"write_only": True}}
def validate(self, data):
# user = None
email = data.get("email", None)
password = data.get("password")
if not email:
raise serializers.ValidationError("Email is required for login")
if not password:
raise serializers.ValidationError("Password is required for login")
user = authenticate(email=email, password=password)
if not user:
raise serializers.ValidationError("This email is not valid/already exists")
return data

Answer 1

序列化程序的验证数据中没有user。请注意，serializer.validated_data['user']没有多大意义，因为您从未将其传递给验证器。

您应该使用将其添加到数据中

def validate(self, data):
# user = None
email = data.get('email', None)
password = data.get('password')
if not email:
raise serializers.ValidationError('Email is required for login')
if not password:
raise serializers.ValidationError('Password is required for login')
user = authenticate(email=email, password=password)
if not user:
raise serializers.ValidationError('This email is not valid/already exists')
data['user'] = user
return data
