"一二三四五六七"

現在來做姓名的排序功能

app/controllers/girb_controller.rb

  def index
    @tab = params[:tab]
    if params[:search]
      @girbs = Girb.search(params[:search]).order("name DESC")
    else
      if @tab == "asc"
        @girbs = Girb.all.order("name ASC")
      elsif @tab == "desc"
        @girbs = Girb.all.order("name DESC")
      else
        @girbs = Girb.all
      end
    end
  end

在 index 頁面做好相關鍵結

app/views/index.html.erb

<div class="container">
  <h1>Index Page of Girb </h1>
  <div>    
    <span class="pull-right">
    <%= link_to girbs_path(tab: "asc") do %> 
      <i class="fa fa-sort-alpha-asc"></i>
    <% end %> 
    <%= link_to girbs_path(tab: "desc") do %> 
      <i class="fa fa-sort-alpha-desc"></i> 
    <% end %>
    </span>
  </div>
