推荐答案

你应该重写 ActionView::Base.field_error_proc.它目前在 ActionView::Base:

You should override ActionView::Base.field_error_proc. It's currently defined as this within ActionView::Base:

 @@field_error_proc = Proc.new{ |html_tag, instance| 
   "<div class="field_with_errors">#{html_tag}</div>".html_safe
 }

您可以通过将它放在 config/application.rb 内的应用程序类中来覆盖它:

You can override it by putting this in your application's class inside config/application.rb:

config.action_view.field_error_proc = Proc.new { |html_tag, instance| 
  html_tag
}

重启 Rails 服务器以使此更改生效.

Restart rails server for this change to take effect.
