ruby-on-rails - 如何将参数从 radio_button_tags 传递到 Controller

Question

这是我的表单，显示所有 feedbacks管理员尚未审核:

每个 feedback 旁边有 2 个单选按钮选择接受或拒绝，值为 1或2 .

<% form_tag moderate_feedbacks_path, :method => :put do %>
  <table>
    <% @all_feedbacks.each do |feedback| %>
    <tr>
      <td><%= radio_button_tag :review_option, '1', false, :name => feedback.id %></td>
      <td><%= radio_button_tag :review_option, '2', false, :name => feedback.id %></td>
      <td><%= feedback.name %></td>
      <td><%= feedback.email %></td>
      <td><%= feedback.message %></td>
    </tr>
    <% end %>
   </table>
<%= submit_tag 'Apply' %>
<% end -%>

我想做的是当我点击submit_tag时，更新review_option每个选定的字段 feedback其值为 radio_button_tag , 1或2

现在我已经有了如您所见的表单，效果很好，但我被困在 Controller 部分:

def moderate_feedbacks
  Feedback.update_all(["review_option = ?", ????])
  redirect_to admin_feedbacks_path
end

如何将参数从这些单选按钮传递到 Controller 。谢谢。

附注 html 来源:

<input id="review_option_1" name="3" type="radio" value="1">
<input id="review_option_2" name="3" type="radio" value="2">

名称取自feedback.id

当我按下submit_tag时的日志看起来像这样；

Processing Admin::FeedbacksController#moderate_feedbacks (for 127.0.0.1 at 2012-10-16 15:36:20) [PUT]
  Parameters: {"commit"=>"Apply", "3"=>"2", "4"=>"1"}

其中3是反馈的id - 2 radio 值，4是反馈的id - 1 radio 值

raise.params["feedback.is"].inspect之后

Parameters:

    {"commit"=>"Apply",
     "3"=>"1",
     "4"=>"1",
     "_method"=>"put"}

好的，答案如下:

在feedback.rb中

   class Status
     ACCEPTED = 1
     REJECTED = 2
   end

在表单中:

<% form_tag moderate_feedbacks_path, :method => :put do %>
  <table>
    <% @all_feedbacks.each do |feedback| %>
    <tr>
      <td><%= radio_button_tag :review_option, Feedback::Status::ACCEPTED, false, :name => feedback.id %></td>
      <td><%= radio_button_tag :review_option, Feedback::Status::REJECTED, false, :name => feedback.id %></td>
      <td><%= feedback.name %></td>
      <td><%= feedback.email %></td>
      <td><%= feedback.message %></td>
    </tr>
    <% end %>
   </table>
<%= submit_tag 'Apply' %>
<% end -%>

在feedbacks_controller.rb中

   def moderate_feedbacks
    params.each do |key, value|
      if key =~ /^r(\d+)/ && !value.blank?
        feedback_id = $1
        Feedback.update_all(["review_option = ?", value.to_i], ["id = ?", feedback_id])
      end
    end
    redirect_to admin_feedbacks_path
  end
