我创建了一个自定义用户，并通过knox身份验证，我想为每个用户创建一个配置文件，这是我的个人资料模型
class Profile(models.Model):
user = models.OneToOneField(User,null=True,on_delete=models.CASCADE)
GENDER = (
('M','Male'),
('F','Female'),
)
username = models.CharField(max_length=150,blank=True)
gender = models.CharField(max_length=1, choices=GENDER,blank=True)
def create(self,user,username):
self.user=user
self.username = username
return self
序列化器
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('id','username','email','phone_number')
class RegisterSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('id','username','email','phone_number','password')
extra_kwargs = {'password':{'write_only':True}}
def create(self, validated_data):
user = User.objects.create_user(
**validated_data
)
username = validated_data['username']
profile = Profile.objects.create(user=user,username=username)
user.set_password(validated_data['password'])
return user,profile
class LoginSerializer(serializers.Serializer):
username = serializers.CharField()
password = serializers.CharField()
def validate(self, data):
user = authenticate(**data)
if user and user.is_active:
return user
raise serializers.ValidationError('Incorrect Credentials')
#serializer for profile
class ProfileSerializer(serializers.ModelSerializer):
class Meta:
model = Profile
fields = ['username','gender']
username = serializers.CharField(source='User.username')
和此为意见
class UserApiView(generics.RetrieveAPIView):
permission_classes = [permissions.IsAuthenticatedOrReadOnly]
serializer_class = UserSerializer
def get_object(self):
return self.request.user
class RegisterApiView(generics.GenericAPIView):
serializer_class = RegisterSerializer
def post(self,request,*args,**kwargs):
serializer = self.get_serializer(data = request.data)
serializer.is_valid(raise_exception=True)
user,profile = serializer.save()
return Response({
'user': UserSerializer(user,context=self.get_serializer_context()).data,
'token':AuthToken.objects.create(user)[1],
'profile':ProfileSerializer(profile,context=self.get_serializer_context()).data
})
class LoginApiView(generics.GenericAPIView):
serializer_class = LoginSerializer
def post(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = serializer.validated_data
return Response({
"user": UserSerializer(user, context=self.get_serializer_context()).data,
"token": AuthToken.objects.create(user)[1]
})
class ProfileApiView(generics.RetrieveAPIView):
serializer_class = ProfileSerializer
permission_classes = [permissions.AllowAny]
def get(self,request,*args,**kwargs):
serializer = self.get_serializer(data=request.data)
return Response({
"username":ProfileSerializer(context=self.get_serializer_context()).data
})
而且，我一般来说对drf和django还是陌生的，我想知道是否有人可以建议一个更好的做法来在注册时为每个用户创建个人资料。
谢谢。
编辑：我尝试执行以下操作：
user,profile = serializer.save()
并产生以下回溯

AttributeError: Got AttributeError when attempting to get a value for field `username` on serializer `ProfileSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `Profile` instance.
Original exception text was: 'Profile' object has no attribute 'User'.
create方法返回user, profile，您只需调用此方法一次，然后使用元组拆包分配user和profile即可
从serializer.save()中删除重复的RegisterApiView。相反，请执行以下操作。
