不推荐使用Python flask.ext.mysql吗? [英] Python flask.ext.mysql is deprecated?

问题描述

当我运行from flask.ext.mysql import MySQL时，得到警告Importing flask.ext.mysql is deprecated, use flask_mysql instead.

When I run from flask.ext.mysql import MySQL I get the warning Importing flask.ext.mysql is deprecated, use flask_mysql instead.

所以我使用pip install flask_mysql安装了flask_mysql，成功安装了它，但是随后当我运行from flask_mysql import MySQL时，我得到了错误No module named flask_mysql.在第一个警告中，我也得到Detected extension named flaskext.mysql, please rename it to flask_mysql. The old form is deprecated. .format(x=modname), ExtDeprecationWarning.您能告诉我如何将其重命名为flask_mysql吗? 预先感谢.

So I installed flask_mysql using pip install flask_mysql,installed it successfully but then when I run from flask_mysql import MySQL I get the error No module named flask_mysql. In the first warning I also get Detected extension named flaskext.mysql, please rename it to flask_mysql. The old form is deprecated. .format(x=modname), ExtDeprecationWarning. Could you please tell me how exactly should I rename it to flask_mysql? Thanks in advance.

推荐答案

flask.ext.是已弃用的模式，在较旧的扩展程序和教程中广泛使用.警告告诉您将其替换为直接导入，它猜测为flask_mysql.但是，Flask-MySQL使用的是甚至更过时的模式flaskext..除了说服维护人员发布可修复该问题的新版本外，您无能为力. from flaskext.mysql import MySQL应该可以工作并避免出现警告，尽管最好将软件包更新为使用flask_mysql.

flask.ext. is a deprecated pattern which was used prevalently in older extensions and tutorials. The warning is telling you to replace it with the direct import, which it guesses to be flask_mysql. However, Flask-MySQL is using an even more outdated pattern, flaskext.. There is nothing you can do about that besides convincing the maintainer to release a new version that fixes it. from flaskext.mysql import MySQL should work and avoid the warning, although preferably the package would be updated to use flask_mysql instead.
