Django测试单独的数据库给出" OperationalError:没有这样的表:auth_user"

标签: django sqlite python-3.x ldap django-rest-framework

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

完整的测试设置在这里: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:

此处也提供了代码:http://dpaste.com/3D2H4NK(语法高亮)。

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。

我完成了所有迁移。

2 个答案:

答案 0 :(得分:1)

运行
    python manage.py makemigrations <appname>
对于INSTALLED_APPS中的每个应用程序。(特别是auth_user上具有ForeignKey字段的应用程序)

我有不同的错误让我来到这里,但认为原因是一样的 django.db.utils.OperationalError: (1005, "Can't create table '<test_db>.#sql-3821_1c9' (errno: 150)")

在这两种情况下,只有在测试时才会创建与auth模块相关的所有表,而不执行makemigrations命令。

的解决方案

答案 1 :(得分:0)

必须要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")

添加后如果&#39; test&#39;对于manage.py的主要方法的东西,应用程序开始正常工作,之后python manage.py测试和python manage.py runserver都使用正确的设置。

但是,我没有让它与PyCharm合作并立即进行测试,如何让它发挥作用。
