如何將對象傳遞給部分？

Question

這不是你如何傳遞一個對象的部分：

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

我的部分看起來像：

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

我得到以下錯誤：

路由錯誤

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，它適用於：

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

我懷疑問題是它沒有正確傳遞@answer對象。我究竟做錯了什麼？

Answer 1

嘗試：

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

然後，在你的部分，稱之爲無@，e.g：

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