如何将对象传递给部分？

Question

这不是你如何传递一个对象的部分：

<% @answers.each do |answer| %> 
    ... 
    <%= render 'form_for_answer_comment', :answer => answer %> ? 
<% end %> 

我的部分看起来像：

<%= form_for([@question, @answer, @comment]) do |f| %> 

我得到以下错误：

路由错误

No route matches {:action=>"create", :controller=>"questions/answers/comments", :format=>nil, :question_id=>#<Question id: 3, user_id: 1, title: "test", description: "asdfasdfasdfasdfasdfasdf\r\n\r\n\tasdfasd", created_at: "2011-09-10 01:33:38", updated_at: "2011-09-10 01:33:38">, :answer_id=>#<Answer id: nil, user_id: nil, question_id: nil, description: nil, selected: nil, created_at: nil, updated_at: nil>} 

但是，它适用于：

<%= form_for([@question, Answer.first, @comment]) do |f| %> 

我怀疑问题是它没有正确传递@answer对象。我究竟做错了什么？

Answer 1

尝试：

<%= render :partial => 'form_for_answer_comment', :locals => { :answer => answer } %> 

然后，在你的部分，称之为无@，e.g：

<%= form_for([@question, answer, @comment]) do |f| %>
