Django测试单独的数据库给出"OperationalError:no such table:auth_user"

Question

我的问题是我想建立一个单独的测试数据库,与我的开发数据库分开.App本身几乎与Django-Rest-Framework快速入门教程相同,只是我使用LDAP后端.我的开发数据库使用MySQL.我有单独的设置文件进行测试.

我在这里放了完整的错误回溯:http://dpaste.com/1W3TX1E,但有趣的部分是:

sqlite3.OperationalError: no such table: auth_user

完整的测试设置如下:http://dpaste.com/1K7KHK4.我的相关设置是(安装的应用程序中缺少pyldap和django-ldap-auth,它们是用pip手动安装的):

    INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'njord',
    'permissions',
]
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': ':memory:',
    }
}

现在,该应用程序基本上只进行LDAP身份验证.我认为这就是为什么我有一个错误 - 当我做测试时,我的数据库中没有任何内容 - 没有用户,没有组.如果用户针对LDAP服务器进行了身份验证,则会在数据库中创建用户以及他/她所在的所有组,因此它会按需发生.

什么有效:我的应用程序的开发版本适用于外部LDAP,并且还可以使用开发数据库进行测试.

什么不起作用:使用sqllite3内存数据库进行测试(我重复一遍,使用开发数据库进行测试并模拟ldap工作).

我测试的代码在这里:

我不确定,问题是什么.我唯一能想到的是,因为创建时数据库中没有用户,所以没有创建数据库,但我不确定.任何帮助深表感谢.

我已完成所有迁移.

必须做的是将这些行添加到manage.py：

if __name__ == "__main__":
    if 'test' in sys.argv:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.test_settings")
    else:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings")

在将 if 'test' 内容添加到 manage.py 的主方法后，应用程序开始正常工作，之后 python manage.py test 和 python manage.py runserver 都可以使用正确的设置。

但是，我还没有让它与 PyCharm 一起工作并现在对其进行测试，如何让它工作。
