通过rails单选按钮传递多个值

Question

我有一个方法在我的控制器中创建一个关联记录:

def updating_rating
      rr = ProductRecommendation.new(:rating_id => rating_set.id, :recommendation_id => r.id)
      rr.save!
  end

我的路由设置为:

match "/recommendations/updating_rating" => "recommendation#updating_rating", :as => 'update'

在我看来，我有:

<div>
<%= form_tag(update_url, :method => :post) do  %>
<%= radio_button_tag(:rating_id, '1', :recommendation_id => rec.recommendation.id) %>
<%= radio_button_tag(:rating_id, '2', :recommendation_id => rec.recommendation.id) %>
<%= radio_button_tag(:rating_id, '3', :recommendation_id => rec.recommendation.id) %>
<% end %>
</div>

这只传递rating_id作为一个值。我如何将rating_id +推荐_id传递给控制器方法。

Answer 1

您可以添加一个隐藏字段:

<%= hidden_field_tag :recommendation_id => rec.recommendation.id %>

然后在控制器中获取:recommendation_id，例如:

params[:recommendation_id]
