【问题描述】：

我正在使用 rails 国际化 api 进行 activerecord 翻译。我在翻译错误消息时遇到了问题。如何翻译来自我项目中不同文件的多个错误消息？我的models 文件夹中有名为application_draft.rb,team.rb,user.rb,todo.rb 的文件。我想翻译其中的错误消息，这是我的en.yml 文件：

errors:
        models:
         -team:
         -application_draft:
         -conference:
         -todo:
         -user:
            attributes:
              roles:
                too_many_reviewers: too many reviewers
                multiple_sel_error: must not be selected twice
                must_accepted: must have been accepted
                one_app_allowed: Only one application may be lodged
                confirmed_email_address: Please make sure every student confirmed the email address.
                wrong_date_sel: must be a later date than start date
                no_more_than_two: "there cannot be more than 2 students on a team."
                cannot_changed: can't be changed

我已经实现了这段代码并抛出了错误（意味着它没有工作）。这是我的application_draft.rb 和todo.rb 错误代码sn-ps 之一：

application.rb:

def different_projects_required
  if project1 && project1 == project2
    errors.add(:projects, :multiple_sel_error)
  end
end

todo.rb

def validate_number_of_reviewers
  errors.add(:user, :too_many_reviewers) if application.todos.count > 3
end

如何翻译这两者避免重复错误？

【问题讨论】：

你能分享确切的错误信息吗？另外，todo.rb 文件 sn-p 似乎在底部有额外的end 但我想你只是复制错了

@mbajur ，是的，todo.rb 中有额外的“结束”，对此感到抱歉。我收到重复错误。我的问题是如何翻译 applcation_draft.rb 和 todo.rb 中的错误日志没有任何重复错误？我使用了上面提到的 en.yml 代码但抛出了这个错误：Failure/Error: expect(todo.errors.messages).to eq({ user: ['too many reviewers'] }) expected: {:user=>["too many reviewers"]} got: {:user=>["translation missing: en.activerecord.errors.models.todo.attributes.user.too_many_reviewers"]}
@mbajur 如何同时翻译多个模型中的消息？

【解决方案1】：

从activerecord继承：

en:
  activerecord:
    errors:
      models:
       -team:
       -application_draft:
       -conference:
       -todo:
       -user:
          attributes:
            roles:
              too_many_reviewers: too many reviewers
              multiple_sel_error: must not be selected twice
              must_accepted: must have been accepted
              one_app_allowed: Only one application may be lodged
              confirmed_email_address: Please make sure every student confirmed the email address.
              wrong_date_sel: must be a later date than start date
              no_more_than_two: "there cannot be more than 2 students on a team."
              cannot_changed: can't be changed

如果它不起作用。我有另一种方式。尝试在方法本身中输入翻译，如下所示

    application.rb:

    def different_projects_required
      if project1 && project1 == project2
        errors.add(:projects, I18n.t('activerecord.errors.models.user.attributes.roles.multiple_sel_error'))
      end
    end

    todo.rb

    def validate_number_of_reviewers
      errors.add(:user, I18n.t('activerecord.errors.models.todo.attributes.roles.too_many_reviewers')) if application.todos.count > 3
    end
