ruby-on-rails - How to achieve Rails close button

Question

I'm would like to have a close button on my rails application messages.

I've read about integrating rails flash messages with twitter bootstrap, but I'm stuck.

Answer 1

这种消息是引导警报。检查 bootstrap 文档，并在 rails 中确保您的应用程序与 boottrap 集成。

为了将闪存消息与引导程序集成，我建议您遵循这种方法：

创建一个部分_flash_messages.html.erb

<% flash.each do |type, message| %>
  <div class="alert <%= bootstrap_class_for(type) %> fade in">
    <button class="close" data-dismiss="alert">×</button>
    <%= message %>
  </div>
<% end %>

然后在你的application.html.erb添加：

<%= render partial: "shared/flash_messages", flash: flash %> 

在你的application_helper.rb：

module ApplicationHelper

  def bootstrap_class_for flash_type
    case flash_type
      when :success
        "alert-success"
      when :error
        "alert-error"
      when :alert
        "alert-block"
      when :notice
        "alert-info"
      else
        flash_type.to_s
    end
  end

end
