TypeError：create_user（）获得关键字参数'name'的多个值

Question

我试图在Django中创建自定义身份验证，其中标识符是电子邮件，有一个名为name和password字段的必填字段。在创建超级用户时，我收到错误消息。

TypeError: create_user() got multiple values for keyword argument 'name' 

这里是我的models.py

from django.db import models 
from django.contrib.auth.models import User 
from django.conf import settings 
from django.contrib.auth.models import (
    BaseUserManager, AbstractBaseUser 
) 


class MyUserManager(BaseUserManager): 
    def create_user(self, name, email, password=None): 
     """ 
     Creates and saves a User with the given email, name and password. 
     """ 
     if not email: 
      raise ValueError('Users must have an email address') 

     user = self.model(
      name=name, 
      email=self.normalize_email(email), 
     ) 

     user.set_password(password) 
     user.save(using=self._db) 
     return user 

    def create_superuser(self, email, name, password): 
     """ 
     Creates and saves a superuser with the given email, name and password. 
     """ 
     user = self.create_user(email, 
      password=password, 
      name=name 
     ) 
     user.is_admin = True 
     user.save(using=self._db) 
     return user 


class MyUser(AbstractBaseUser): 
    email = models.EmailField(
     verbose_name='email address', 
     max_length=255, 
     unique=True, 
    ) 
    name = models.CharField(max_length=20) 
    is_active = models.BooleanField(default=True) 
    is_admin = models.BooleanField(default=False) 

    objects = MyUserManager() 

    USERNAME_FIELD = 'email' 
    REQUIRED_FIELDS = ['name'] 

    def get_full_name(self): 
     # The user is identified by their email address 
     return self.email 

    def get_short_name(self): 
     # The user is identified by their email address 
     return self.email 

    # On Python 3: def __str__(self): 
    def __unicode__(self): 
     return self.name 

    def has_perm(self, perm, obj=None): 
     "Does the user have a specific permission?" 
     # Simplest possible answer: Yes, always 
     return True 

    def has_module_perms(self, app_label): 
     "Does the user have permissions to view the app `app_label`?" 
     # Simplest possible answer: Yes, always 
     return True 

    @property 
    def is_staff(self): 
     "Is the user a member of staff?" 
     # Simplest possible answer: All admins are staff 
     return self.is_admin 


class MyUser(AbstractBaseUser): 
    name = models.CharField(max_length=20) 
    email = models.CharField(max_length=40, unique=True) 
    REQUIRED_FIELDS = ['name'] 
    USERNAME_FIELD = 'email' 

这里是回溯

File "/usr/local/lib/python2.7/dist-packages/django/contrib/auth/management/commands/createsuperuser.py", line 141, in handle 
    self.UserModel._default_manager.db_manager(database).create_superuser(**user_data) 
    File "/home/jaskaran/coding/django/TaskMan/taskmanager/models.py", line 32, in create_superuser 
    name=name 
TypeError: create_user() got multiple values for keyword argument 'name' 

Answer 1

更改您的函数调用

user = self.create_user(email, 
     password=password, 
     name=name 
    ) 

到

user = self.create_user(email=email, # use email=email 
     password=password, 
     name=name 
    ) 

您的参数顺序不正确。在name之前通过email，然后再次将name作为关键字参数传递。
