Ruby on rails 通过关联实现太阳黑子搜索的问题

我在实现太阳黑子时遇到了一些问题！在过去的两天里，我一直在努力让它工作，但我似乎找不到任何解决方案（尽管毫无疑问，它一直盯着我的脸！）

我希望用户能够搜索一个汽车制造商。创建车辆时，将通过关联为其指定制造商（如下所示）。现在我如何允许用户输入搜索字段（或者更好地选择所有制造商的集合）并将结果过滤掉

在一个理想的世界里，我希望这能成为我的搜索：

<%= simple_form_for :search,  url: vehicles_path , :method => :get do |f| %>
    <%= select_tag :manufacturer, options_from_collection_for_select(Manufacturer.all, :id, :name) %> 
    <%= submit_tag "Search", :name => nil %>
<% end %>

问题在于您在控制器中执行搜索的方式。 您曾说过，在理想情况下，您希望从选择元素中选择制造商：

<%= simple_form_for :search,  url: vehicles_path , :method => :get do |f| %>
<%= select_tag :manufacturer, options_from_collection_for_select(Manufacturer.all, :id, :name) %> 
<%= submit_tag "Search", :name => nil %>

太阳黑子文件说：

未定义为文本的字段（例如，整数、布尔值、时间等）可用于在执行全文匹配之前确定（限制）查询的范围
