python - 使用 sqlite3 db 缺少表的单元测试 django 项目

Question

Missing Table When Running Django Unittest with Sqlite3

我已经看过这篇文章，并正在尝试设置我的项目进行测试。每当我尝试运行任何数据库命令时，都会出现错误。我遇到的问题是，当我尝试执行 manage.py syncdb 时，我收到一个数据库错误，说即使它当前位于模型文件和生产数据库中，也不存在这样的表。

这是追溯。

django.db.utils.DatabaseError: no such table: Utilities_language

这是在我的 settings.py 文件中

if 'test' in sys.argv or 'jenkins' in sys.argv:
DATABASES = {
             'default': {
                         'ENGINE': 'django.db.backends.sqlite3',
                         'NAME': 'test_ndptc'
                         }
             }

如果我将上述 if 语句设置为 true 并尝试运行 manage.py syncdb，也会发生同样的错误。

这是导致问题的模型。

Answer 1

我也有这个问题。原来我必须在 settings.py 文件中添加一个 TEST_NAME 属性才能正确识别测试数据库。它为我解决了这个问题:

if 'test' in sys.argv:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
            'TEST_NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
        }
    }
