python - 如何禁用 django 迁移调试日志记录？

Question

非常类似于lafagundes question about south migration debug logging ，除了我没有使用 south - 我使用的是普通的 Django 1.7 迁移。我也在使用 django-nose测试运行器。

当我运行 manage.py test 时，没有捕获调试日志输出:

(codesy)lcrouch:codesy lcrouch$ ./manage.py test
nosetests --verbosity=1
Creating test database for alias 'default'...
......E...............................
======================================================================
ERROR: test_return_state (auctions.tests.utils_tests.IssueStateTest)
----------------------------------------------------------------------

当我运行单个测试模块时，例如 ./manage.py test auctions.tests.utils_tests，调试日志输出包括所有 django.db.backends.schema : DEBUG 行涉及 Django 迁移:

(codesy)lcrouch:codesy lcrouch$ ./manage.py test auctions.tests.utils_tests
nosetests auctions.tests.utils_tests --verbosity=1
Creating test database for alias 'default'...
E
======================================================================
ERROR: test_return_state (auctions.tests.utils_tests.IssueStateTest)
----------------------------------------------------------------------

django.db.backends.schema: DEBUG: CREATE TABLE "django_content_type" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "name" varchar(100) NOT NULL, "app_label" varchar(100) NOT NULL, "model" varchar(100) NOT NULL); (params [])

...
django.db.backends.schema: DEBUG: DROP TABLE "socialaccount_socialapp"; (params [])
django.db.backends.schema: DEBUG: ALTER TABLE "socialaccount_socialapp__new" RENAME TO "socialaccount_socialapp"; (params [])

这真的很难回到真正的失败。

如何禁用此输出？在 django 或 Nose 水平？

Answer 1

如果您不介意在测试中禁用迁移，您可以通过将以下内容添加到您的 settings.py 中来实现:

TESTING = 'test' in sys.argv

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

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

    MIGRATION_MODULES = DisableMigrations() 

这只会一次性创建数据库，而不是逐步完成每个迁移。

如果您想在测试中保持迁移运行，您可以通过更新日志记录设置来删除消息。

TESTING = 'test' in sys.argv

if TESTING:
    LOGGING = {
        'version': 1,
        'handlers': {
            'file': {
                'level': 'DEBUG',
                'class': 'logging.FileHandler',
                'filename': '/tmp/codesy-debug.log',
            },
        },
        'loggers': {
            'django.db.backends.schema': {
                'handlers': ['file'],
                'propagate': True,
                'level': 'INFO',
            },
            '': {
                'handlers': ['file'],
                'level': 'DEBUG',
            }
        }
    }
