Question

我已经创建了一个要在Azure上托管的Django应用程序，因此我使用Python Tools for Visual Studio来开发应用程序。我在我的根应用程序中的models.py中创建了一个名为Client的模型。它实际上是一个模型表格，因为表格列都链接到我创建的表单中的字段。我正在使用MySQL，连接器是MySQLClient，因为我正在使用Python 3.4。我跑了python manage.py syncdb，显示了以下内容：

Operations to perform:
 Synchronize unmigrated apps: staticfiles, messages, VSpace
 Apply all migrations: auth, sessions, contenttypes, sites
Synchronizing apps without migrations:
 Creating tables...
  Creating table VSpace_Client
  Running deferred SQL...
 Installing custom SQL...
Running migrations:
 Rendering model states... DONE
 Applying auth.0001_initial...Traceback (most recent call last):

这就是失败的地方。我正在研究这个，我遇到了一些关于创建超级用户的事情。我试过了，但在输入凭证后它也失败了。有谁知道为什么会这样？

The above exception was the direct cause of the following exception:

Answer 1

首先，尝试运行python manage.py migrate而不是syncdb。如果我没记错的话，syncdb命令被弃用，而不是makemigrations和migrate命令。试试吧，事情应该会好转。

相关：您使用的是哪个版本的Django？

Answer 2

删除迁移文件夹中的所有文件。
运行：python manage.py makemigrations
运行：python manage.py migrate
运行：python manage.py createsuperuser

正如JwM所说，syncdb已被弃用，现在使用makemigrations和migrate

Answer 3

您的数据库中已存在auth_permissions表，但迁移认为它不存在。尝试伪造迁移以超越这一点。

./manage.py migrate auth --fake

应用auth.0001_initial时，Django syncdb失败
