python - 不在使用WAMP SERVER Django/Mezzanine的MYSQL中创建表

我创建了像

models.py文件：

from django.db import models
from mezzanine.pages.models import Page

class Author(Page):
    dob = models.DateField("Date of birth")

并通过编写命令south然后编写easy_install South命令安装python manage.py createdb, python manage.py syncdb and python mange.py migrate，这些操作表明表已创建，但是在数据库中未创建表时。

这是我的settings.py文件

更新：

我的项目名称是mpj now。
   我正在使用Wamp保存数据库/表。
   我的数据库名称是abcdef
   我的数据库中没有表，但是在运行迁移命令后仍然显示我的警告/错误。
   Django在我的Wamp服务器上运行良好，然后为什么夹层显示“您的数据库不支持运行模式更改语句”的错误

在这里，我附有夹层迁移产生的此错误的图像。

注意：我在“已安装的应用”中提到了“南”。

最佳答案

解：

转到项目文件夹并打开local_settings.py文件，然后定义您的数据库，如下所示：

DATABASES = {
    "default": {
        # Ends with "postgresql_psycopg2", "mysql", "sqlite3" or "oracle".
        "ENGINE": "django.db.backends.mysql",
        # DB name or path to database file if using sqlite3.
        "NAME": "abc",
        # Not used with sqlite3.
        "USER": "root",
        # Not used with sqlite3.
        "PASSWORD": "123",
        # Set to empty string for localhost. Not used with sqlite3.
        "HOST": "",
        # Set to empty string for default. Not used with sqlite3.
        "PORT": "",
    }
}

在local_settings.py和settings.py文件中定义数据库
