覆盖扩展AbstractBaseUser的django模型保存功能

Question

使用restframework进行用户注册 我需要在保存之前生成随机密码，我重写模型中的保存方法，但是这种方式永远不会运行并且需要丢弃消息密码字段。 ¿我如何覆盖这个？谢谢。

新增或更新您的代码

AgentSerializer（serializers.py）

class AgentSerializer(serializers.ModelSerializer): 
    class Meta: 
     model = Agents 

    def create(self, validated_data): 
     return Agents.objects.create(**validated_data) 

在views.py

class AgentViewSet(viewsets.ModelViewSet): 
    queryset = Agents.objects.all() 
    serializer_class = AgentSerializer 
    permission_classes = (permissions.AllowAny,) 
    http_method_names = ['post'] 

    def create(self, request): 
     serializer = self.serializer_class(data=request.data) 

     if serializer.is_valid(): 
      Agents.objects.create_user(**serializer.validated_data) 

      return Response(serializer.validated_data, status=status.HTTP_201_CREATED) 

     return JSONResponse(serializer.errors, status=400) 

在models.py：

class MyUserManager(BaseUserManager): 
    def _create_user(self, email, password, 
       is_staff, **extra_fields): 
     password= # Generate random password 
     email = self.normalize_email(email) 
     user = self.model(email=email, 
     is_staff=is_staff, **extra_fields) 
     user.set_password(password) 
     user.save(using=self._db) 
     return user 
    def create_user(self, email, password=None, **extra_fields): 
     return self._create_user(email, password, False 
          **extra_fields)

试试在您的MyUserManager中重写create_user方法。喜欢的东西：

def create_user(self, **kwargs): 
    kwargs['password'] = # Generate random password 
    return super().create_user(**kwargs)
