Question

一个类中的字符串没有被翻译，下面的代码快照说明了这个问题。

应该发生的是，当您击中烧瓶路径时，两个消息均为英文。然后点击浏览器刷新，这两种消息都应该被翻译。只会翻译msg2。

味精和味精2的区别在于味精来自该类。

我可以从打印语句中得知，更改语言后，将调用localeselector，并且由于msg2已翻译，因此可以正确设置语言环境。它几乎像msg一样被缓存为英语，并且当显示在类中时，翻译器不会对其进行解析。

也许这是预期的限制？如果是这种情况，首选的解决方法是什么？

    print("language - index: {}".format(language))
    msg = myclass.text()
    msg2 = _("for all good men")

    # change language
    language = 'zh_Hans'
    app.config['BABEL_DEFAULT_LOCALE'] = 'zh_Hans'
    session['language'] = 'zh_Hans'
    refresh()

    # PROBLEM: On 2nd page refresh, msg2 is translated, msg is NOT
    return 'Index Page: {} {}'.format(msg, msg2)


@babel.localeselector
def get_locale():
    print("language localeselector: {}".format(language))
    return language


class BaseConfig(object):
    SUPPORTED_LANGUAGES = ['en', 'zh_Hans']
    BABEL_DEFAULT_LOCALE = 'en'
    BABEL_DEFAULT_TIMEZONE = 'UTC'


app.config.from_object(BaseConfig)
app.run(host="0.0.0.0", port=6800, debug=False)
