从参数填充复选框

Question

我的页面列出了路径并提供了基于文本的搜索 - 请在此处查看当前版本http://www.trailsee.com/trails。我正在添加一个表单来过滤搜索结果，例如按难度，活动，长度，允许狗等。我有过滤器工作，但它没有在用户可以选择多个项目的复选框字段中加载以前使用的参数，例如搜索后允许骑自行车，允许远足等。它目前只加载最大价值的参数。例如如果我有参数难度=0&difficulty=1&difficulty2，它只会加载选择难度2的页面。

特别是 :travel_type (radio)、:difficulty (checkbox)、:dogs (checkbox) 和 :action_types (checkbox) 有问题。

这是一个带有参数的示例 URL http://localhost:3000/trails?utf8=%E2%9C%93&travel_type=on&max_time=168&max_distance=35&difficulty=0&difficulty=1&difficulty=2&dogs=1&dogs=2&action_types=1&action_types=2&action_types=3&commit=Filter

重新加载时 选择了 travel_type 2 难度2被选中 狗 2 被选中 action_types 3 被选中

这是我用 slim 编写的视图代码

Answer 1

您将使用&difficulty=0&difficulty=1&difficulty=2 覆盖您的 params[:difficulty] 变量，您必须为每个复选框指定一个唯一的 params 变量名称。

 div.difficulty
      strong Difficulty
      div
      p
        = check_box_tag :difficulty0, true, false 
        = label_tag 
          i class='sprite-icon-difficulty-0'
        = check_box_tag :difficulty1, true, false
        = label_tag 
          i class='sprite-icon-difficulty-1'
        = check_box_tag :difficulty2, true, false
        = label_tag 
          i class='sprite-icon-difficulty-2'
