django auth系统'创建'

Question

我正在使用django 1.7.11。我有一个预先存在的项目，我决定尝试使用内置的管理面板（我还没有创建超级用户）。当我打开auth页面时，我看到了：

认为表格可能有问题我决定删除sqlite数据库并重新运行所有内容：

$ python manage.py makemigrations app1
Migrations for 'app1':
  0001_initial.py:
    - Create model Seller

$ python manage.py migrate
Operations to perform:
  Synchronize unmigrated apps: crispy_forms
  Apply all migrations: admin, contenttypes, auth, app1, sessions
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  Applying app1.0001_initial... FAKED

$ python manage.py syncdb
Operations to perform:
  Synchronize unmigrated apps: crispy_forms
  Apply all migrations: admin, contenttypes, auth, app1, sessions
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  No migrations to apply.

You have installed Django's auth system, and don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Created:
Error: '' value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format.
Created:

我该如何解决这个问题？

编辑：

APP1 / models.py：

from django.db import models
    # from django.contrib.auth.models import AbstractUser



    class Seller(models.Model):

        # Address
        contact_name = models.CharField(max_length=50)
        contact_address = models.CharField(max_length=50)
        contact_email = models.CharField(max_length=50)
        contact_phone = models.CharField(max_length=50)
        ............
        created = models.DateTimeField(auto_now_add=True,unique=True)

        REQUIRED_FIELDS = ('contact_name','contact_email','contact_address','contact_phone')
        USERNAME_FIELD = 'created'

Answer 1

您的username字段设置为created。将其更改为contact_name以使用＆＃34; name＆＃34;登录。

但是！...您应该扩展AbstractUser模型，除非您真的需要，否则不要更改USERNAME_FIELD。您现在的方式是要求您编写自定义登录视图等。

编辑：

要使用默认用户模型，只需从settings.py中删除AUTH_USER_MODEL行，然后重新运行createsupseruser管理命令。然后返回管理员登录页面并使用用户名和密码登录。
