ValueError: No module named 'notmigrations' during unit tests

Question

我有带 django-tenant 插件的 django 应用程序 2.1.7（在数据库中为 saas 创建模式）。

我的问题是单元测试。我运行命令： python manage.py test --settings=project.settings_test 我收到一个错误：ImportError: No module named 'notmigrations'

我的代码在 settings_test 文件中

from .settings_base import *


class DisableMigrations(object):
    def __contains__(self, item):
        return True

    def __getitem__(self, item):
        return 'notmigrations'

MIGRATION_MODULES = DisableMigrations()

Answer 1

您正在使用一个古老的 hack，用于真正旧版本的 Django (< 1.9)，在测试中支持禁用迁移之前。由于您现在使用的是相对较新版本的 Django (2.1.7)，因此请从您的测试设置模块中删除该代码。

如果您想在测试中禁用迁移，请使用 the modern approach, which is putting the value to None in MIGRATION_MODULES setting。

When you supply None as a value for an app, Django will consider the app as an app without migrations regardless of an existing migrations submodule. This can be used, for example, in a test settings file to skip migrations while testing (tables will still be created for the apps’ models).

# test_settings.py
from settings import *

MIGRATION_MODULES = {
    'auth': None,
    'contenttypes': None,
    'sessions': None,
    ...
    'myapp1': None,
    'myapp2': None,
}
