ruby-on-rails - 使用工具提示、rails 进行客户端验证

Question

在我的 Rails 应用程序中，我使用客户端验证来显示错误消息。我想使用引导程序在工具提示上显示此消息。如何更改我的代码以便它显示在工具提示中。现在错误消息来自 config/initializers/client_side_validation.rb

 ActionView::Base.field_error_proc = Proc.new do |html_tag, instance|
   unless html_tag =~ /^<label/
     %{<div class="field_with_errors">#{html_tag}<label for="#{instance.send(:tag_id)}"    class="message">#{instance.error_message.first}</label></div>}.html_safe
   else
     %{<div class="field_with_errors">#{html_tag}</div>}.html_safe
   end
end 

请给任何建议。提前致谢。

这对我有用：

ActionView::Base.field_error_proc = Proc.new do |html_tag, instance|
  unless html_tag =~ /^<label/
    %{<div class="field_with_errors">#{html_tag}<div class="tooltip-validate fade right in" style="display: block;"><div class="tooltip-validate-arrow"></div><div class="tooltip-validate-inner"><label for="#{instance.send(:tag_id)}" class="message">#{instance.error_message.first}</label></div></div></div>}.html_safe
  else
    %{<div class="field_with_errors">#{html_tag}</div>}.html_safe
  end

end
