Question

我在Rails中有一个form_tag，如下所示：

    <%= form_tag(listings_path, method: :get) do %>
      What 
      <%= text_field_tag :title, "",class: 'form-control' %>

      Category
      <%= select_tag(:category_id, options_from_collection_for_select(Category.all, :id, :name), { :prompt => 'All Categories' }) %>

      Area 
      <%= select_tag(:area, options_for_select(['All', 'Ireland', 'UK']), class: "form-control") %>

      <%= submit_tag 'Search', name: nil, class: "btn btn-primary" %>
    <% end %>

我应该在哪里添加CSS选项＆gt;＆gt; class：＆＃34; form-control＆＃34; ＆LT;＆LT;为区域字段让它工作？我尝试了几个我在SO上找到但没有运气的选项

Answer 1

我在我的应用程序中将它设置为与您略有不同，但这样做有效。

...

<% options = options_from_collection_for_select(Category.all, :id, :name) %>
<%= f.select :category_id,  options, class: "form-control", :include_blank => 'All Categories' %>

...

Answer 2

<%= select_tag "area", options_for_select(['All', 'Ireland', 'UK']), :include_blank => '--Choose an option--', class: 'form-control' %>

Answer 3

转到应用＆gt;＆gt;资产＆gt;＆gt;样式表并在任何scss页面发布

Rails select_tag css with options_from_collection_for_select
