带复选框的 Rails 元搜索 search_form

我有点困惑。尽管这里有围绕这个主题的所有问题，但我找不到正确的解决方案。

我想要做的就是简单地将复选框添加到我的索引过滤器表单中。

我正在使用 Metasearch gem，这是我当前的代码：

  <form class="filter_form">
     <%= form_for @search do |f| %>
       <%= f.collection_select :categories_id_equals, Category.all, :id, :name, :include_blank => true, :prompt => "All categories" %>
       <%= f.collection_select :location_id_equals, Location.all, :id, :name, :include_blank => true, :prompt => "All locations" %>

       <ul> 
          <b> Type </b>     
          <% Type.all.each do |type|%>
        <li>
          <%= check_box_tag :types_id_equals, type.id %>
          <%=h type.name %>
        </li>
          <% end %>
      </ul>
       <%= submit_tag "Find Now", :class => "find" %>
     <% end %>

除了复选框之外，一切正常。

我在 Rails 方面没有太多经验，所以我真的不明白我做错了什么以及什么是最方便和最简单的方法。

解释 - 我有一个模型 Trips，它与两个模型有 HABTM 关系（类别、类型）并且属于位置。

我希望能够按类别（f.collection select）、位置（f.collection select）和类型（复选框）过滤其索引上的行程。

检查类型并提交后 - 没有任何变化，没有进行过滤！

I am a little confused.
Despite all questions around this theme here, I can't find the right solution.

What I want to do is to simply add check-boxes to my index filter form.

I am using Metasearch gem and here is my current code :

  <form class="filter_form">
     <%= form_for @search do |f| %>
       <%= f.collection_select :categories_id_equals, Category.all, :id, :name, :include_blank => true, :prompt => "All categories" %>
       <%= f.collection_select :location_id_equals, Location.all, :id, :name, :include_blank => true, :prompt => "All locations" %>

       <ul> 
          <b> Type </b>     
          <% Type.all.each do |type|%>
        <li>
          <%= check_box_tag :types_id_equals, type.id %>
          <%=h type.name %>
        </li>
          <% end %>
      </ul>
       <%= submit_tag "Find Now", :class => "find" %>
     <% end %>

All works fine, except the checkboxes.

I don't have much experience in rails, so I don't really see what I am doing wrong and what could be the most convenient and simplest way.

Update
.....................

More explanation - I have a model Trips, which has HABTM relationship with two models (
Categories, Types) and belongs to Location.

I want to be able to filter Trips on it's index by categories (f.collection select) ,location (f.collection select) and types (checkboxes).

After checking types and submitting - nothing changes, no filtering is done!

我是这样处理的。

<% @sub_categories.each do |cat| %>
   <h2><%= cat.name %> <%= check_box_tag "q[product_category_id_in][]", cat.id %></h2>
<% end %>

基本上，q 就是您的查询参数，然后是您的 meta_search 方法中括号内的 sub 。我使用了whatever_foreign_key_in，因为我希望能够将多个id添加到数组中进行搜索。然后在其后添加空括号，以便 Rails 正确处理后参数。

Here's how I handled it.

<% @sub_categories.each do |cat| %>
   <h2><%= cat.name %> <%= check_box_tag "q[product_category_id_in][]", cat.id %></h2>
<% end %>

Basically just q is whatever your query param is, then right after that in brackets sub in your meta_search method. I used whatever_foreign_key_in since I want to be able to add more than one id to the array to search on. Then add empty brackets after it so rails handles the post params correctly.

<%= check_box_tag "type_ids[]", type.id %>

会为你做的。选定的 ID 将作为用逗号分隔的字符串进行传输。您可以在 params[:type_ids] 中找到它们，但您必须手动处理它们！ Rails 不是魔术师，它是一个框架。

<%= check_box_tag "type_ids[]", type.id %>

Will do it for you. The selected ids will be transfered as a string seperated by commatas. You can find them in params[:type_ids] but you have to deal with them manually! Rails is not a magican, its a framework.
