模型验证中的 Rails 国际化 (I18n):可能与否? [英] Rails Internationalization (I18n) in model validations: Possible or not?

问题描述

我在模型中有以下验证:

I have the following validation in a model:

validates_inclusion_of :whatever, :in => [true, false], :message => I18n.t('please_select_whatever')

翻译似乎在生产模式下不起作用:在所有语言中，总是显示英文翻译(可能是因为我在我的应用程序中将英语设置为默认语言环境...?).

It seems that the translation does not work in production mode: in all languages it's always the english translation that gets diplayed (probably because I set english as the default locale in my app...?).

所以我假设我们不能翻译模型中的验证，因为模型只加载一次 - 当服务器启动时(然后，将应用默认语言环境).

So I am assuming that we can't translate validations in models, because models get loaded only once - when the server is booted (and then, the default locale would be applied).

我说的对吗?如果是，你会如何解决这个问题?

Am I right? If yes, how would you solve this problem?

感谢您的帮助！

推荐答案

解决方案是不要在模型中包含任何 custom 消息键，例如...

The solution is to NOT include any custom message keys in the models, like...

:message => I18n.t('activerecord.errors.models.my_model.attributes.whatever.please_select_whatever')

然后模型将应用默认消息键，例如在validates_inclusion_of"的情况下为:inclusion"

The model will then apply the default message keys, for example ":inclusion" in the case of "validates_inclusion_of"

...在 config/locales/en.yml 中你需要:

...and in config/locales/en.yml you need to have:

en:
  activerecord:
    errors:
      models:
        my_model:
          attributes:
            whatever:
              inclusion: "Please select whatever." # see default key: "inclusion"
