在Rails中从索引页提交表单

Question

我是Rails新手。

如何制作一个表单，允许用户通过Home#索引视图中的单选按钮选择语言(en,fr等)提交到Home#语言操作?

Thanks in advance

Answer 1

<%= form_tag language_path, :method => :post do %>
  <%= label_tag :language_english, 'English' %>
  <%= radio_button_tag :language, 'english' %>
  <%= label_tag :language_french, 'French' %>
  <%= radio_button_tag :language, 'french' %>
  <%= submit_tag %>
<% end %>

其中language_path是在routes.rb中定义的路径，例如

match "/home/language" => "home#language", :as => 'language'
