Question

Rails 3.2

在我的 config/locales/en.yml 中，我有：

mailers:
  message_notifier:
    notify_admin_subject: ' added a comment to ticket '
    user_name: 'User: '
    email_address: 'Email: '
    company_name: 'Company: '
    added_following_comment: 'Added the following comment: '
    to_ticket: 'To Ticket: '

在我的 app/mailers/message_notifier.rb 中，我有以下内容：

def notify_admins_when_ticket_has_new_comment(comment)
  @global_admin = User.find("global-admin")
  email_to = @global_admin.email
  @user = User.find(comment.user_id)
  msg = [t(mailers.message_notifier.user_Name) + @user.first_name + ' ' + @user.last_name]
  msg << (t(mailers.message_notifier.email_address) + @user.email)
  msg << (t(mailers.message_notifier.company_name) + @user.company.name)
  msg << (t(mailers.message_notifier.added_following_comment) + @comment.content)
  @ticket = Ticket.find(@comment.commentable_id)
  msg << (t(mailers.message_notifier.to_ticket) + @ticket.number)
  plain_msg = ''
  html_msg = ''
  msg.each do |m|
    plain_msg = plain_msg + m + '\n'
    html_msg = html_msg + m + "<br>"
  end
  subject = @user.email + (t(mailers.message_notifier.notify_admin_subject)) + @ticket.number
  mail(to: email_to, subject: subject) do |format|
    format.text { render text: plain_msg.html_safe }
    format.html { render text: html_msg.html_safe }
  end
end

但是，我收到以下错误消息：

NameError (undefined local variable or method `mailers' for #<MessageNotifier:0x007faf5f540810>):
app/mailers/message_notifier.rb:24:in `notify_admins_when_ticket_has_new_comment'

阅读 I18n API 文档后，我的印象是，这是正确的做法。我做错了什么？

Answer 1

您必须注意语法：t("mailers.message_notifier.user_name") 而不是 t(mailers.message_notifier.user_Name)。请注意，t 方法的参数必须是字符串，并且 uppercase/lowercase 在您定义翻译键时很重要。
