create_user() 缺少 1 个必需的位置参数："用户名"错误，使用 python-social-auth 登录时出错

Question

我创建了一个自定义的AbstractUser用户模型，并使用python社交身份验证通过Steam登录用户。但是当我尝试登录用户时，我会收到这个错误。我曾尝试将用户名添加到REQUIRED_FIELDS，但两种方式都会出现相同的错误。

我已经添加了managers.py和更新了models.py代码，但仍然存在相同的错误。

Answer 1

我为我的项目找到了一个有效的解决方案。我不完全确定为什么会这样，但它很好用，我得到了我需要的一切。

我不得不为我的自定义用户模型创建我自己的用户管理器，我发现create_user方法中的用户名没有值，但值在extra_fields中。所以这是我的解决方案的代码，对我来说是有效的

型号.py

from django.db import models
from django.conf import settings
from django.contrib.auth.models import AbstractUser
from .managers import CustomUserManager

# Create your models here.
class CustomUser(AbstractUser):
username = models.CharField(max_length=32, blank=True, null=True)
name = models.CharField(max_length=200, unique=True, blank=True, null=True)
steam_id = models.CharField(max_length=17, unique=True, blank=True, null=True, db_column='steam_id')
player = models.TextField(null=True)
user_coins = models.FloatField(default=0)
is_active = models.BooleanField(default=True, db_column='status')
is_staff = models.BooleanField(default=False, db_column='isstaff')
is_superuser = models.BooleanField(default=False, db_column='issuperuser')
USERNAME_FIELD = "name"
REQUIRED_FIELDS = []
objects = CustomUserManager()
def has_perm(self, perm, obj=None):
return self.is_superuser
def has_module_perms(self, app_label):
return self.is_superuser

管理员.py

from django.contrib.auth.base_user import BaseUserManager
class CustomUserManager(BaseUserManager):
def _create_user(self, username, password, is_staff, is_superuser, **extra_fields):
if not username:
raise ValueError('Steam name must be set')
user = self.model(
username=username,
steam_id=extra_fields['player']['steamid'],
is_active=True,
is_staff=is_staff,
is_superuser=is_superuser,
player=extra_fields['player']
)
if password:
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, password=None, **extra_fields):
return self._create_user(extra_fields['name'], password, False, False, **extra_fields)
def create_superuser(self, username, password=None, **extra_fields):
user=self._create_user(username, password, True, True, **extra_fields)
user.save(using=self._db)
return user

设置.py

USER_FIELDS = ['username', 'player']
SOCIAL_AUTH_PIPELINE = (
