我有一个测试套件在使用 sqlite 文件时通过，但不在内存中。有没有人遇到过这个问题？

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'db.sqlite3',
    }
}

...测试通过。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': ':memory:',
    }
}

...测试失败

DatabaseError: no such table: foo_bar

有没有办法在测试运行之前强制创建所有表？下面的完整堆栈跟踪

您cms.bulkimport.BaseContentBulkUploadForm正在尝试在导入时执行数据库查询。在您的跟踪中，Django 仍在发现/构建测试套件的过程中，尚未创建测试数据库。您需要找到在导入时执行查询的代码（看起来像m2m_column_help_text）并重构它。
