添加超级用户时 Django SYNCDB 失败（Windows 7、mySQL、Django 1.2.4、mySQL 5.5）

Question

创建超级用户时syncdb失败

Django：v 1.2.4 蟒蛇：2.6 MySQL 服务器：5.5 Windows 7的 额外：MySQL-Python v1.2.3

哪些步骤会重现问题？ 1.安装以上程序 2.创建项目 3. 运行同步数据库

注意：我已经安装了支持 UTF 8 的 mySQL。我还使用 CREATE DTABASE mysite_db CHARACTER SET = UTF8; 创建了 mysite_db 数据库；

预期的输出是什么？你看到了什么？

syncdb 创建所需的表如下：

---

C:\DjangoProjects\mysite>python manage.py syncdb
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_user_permissions
Creating table auth_user_groups
Creating table auth_user
Creating table auth_message
Creating table django_content_type
Creating table django_session
Creating table django_site

You just installed Django's auth system, which means you don't have any superuse
rs defined.
Would you like to create one now? (yes/no):

我选择“是”并收到以下错误：

您使用的是什么版本的产品？在什么操作系统上？

Django：v 1.2.4 蟒蛇：2.6 MySQL 服务器：5.5 Windows 7的 额外：MySQL-Python v1.2.3

请在下面提供任何其他信息。

我还安装了 mySQL C++ 和 ODBC 数据库连接器。 非常感谢任何帮助。

Answer 1

看起来您在开发机器上的登录名中有一个 unicode 字符，而当 createsuperuser.py 模块查找具有该用户名的 User 对象时，这很糟糕，因为 MySQL 不期望这些字符。您可以change the collation settings on your MySQL tables 接受 UTF-8 或使用没有 unicode 字符的用户名（这不是一个很好的选择）。

traceback中真正的失败从第71行的createsuperuser.py开始，源于第59行here：

        try:
         default_username = getpass.getuser().replace(' ', '').lower()
     except (ImportError, KeyError):
         # KeyError will be raised by os.getpwuid() (called by getuser())
         # if there is no corresponding entry in the /etc/passwd file
         # (a very restricted chroot environment, for example).
         default_username = ''

     # Determine whether the default username is taken, so we don't display
     # it as an option.
     if default_username:
         try:
             User.objects.get(username=default_username)
         except User.DoesNotExist:
             pass
         else:
             default_username = ''

它通过getpass 获取您的用户名，然后尝试在User 表中查找。

Answer 2

看起来您的 models.py 或夹具中的某处有 unicode 字符。将文件转换为 UTF-8 并在第一行添加注释：

#coding-utf-8

另外，在 unicode 字符串之前添加u，像这样：

name = CharField(maxlength=255, default=u"утф-8 строка");
