Rails fields_for fields_for不與父級ID關聯的行

Question

我想將一些自定義問題添加到表單底部。然而，問題的id不與答案字段相關聯。我會怎麼做呢？

input.html.erb

<% @event.event_questions.each do |question| %> 
    <%= f.simple_fields_for :event_question, question do |answer| %> 
    <%= answer.simple_fields_for :event_answer do |e| %> 
     <%= e.input :answer, label: question.question %> 
    <% end %> 
    <% end %> 
<% end %> 

output.html

<div class="form-group string required participant_event_question_event_answer_answer"><label class="string required control-label" for="participant_event_question_event_answer_answer"><abbr title="required">*</abbr> Goals</label><input class="string required form-control" type="text" name="participant[event_question][event_answer][answer]" id="participant_event_question_event_answer_answer" /></div> 
<div class="form-group string required participant_event_question_event_answer_answer"><label class="string required control-label" for="participant_event_question_event_answer_answer"><abbr title="required">*</abbr> Action Plan</label><input class="string required form-control" type="text" name="participant[event_question][event_answer][answer]" id="participant_event_question_event_answer_answer" /></div> 
<div class="form-group string required participant_event_question_event_answer_answer"><label class="string required control-label" for="participant_event_question_event_answer_answer"><abbr title="required">*</abbr> Vision</label><input class="string required form-control" type="text" name="participant[event_question][event_answer][answer]" id="participant_event_question_event_answer_answer" /></div>

假設你有question_id在answers表，你可以試試下面的代碼。

<% @event.event_questions.each do |question| %> 
    <%= f.simple_fields_for :event_question, question do |answer| %> 
    <%= answer.simple_fields_for :event_answer do |e| %> 
     <%= e.input :answer, label: question.question %> 
     <%= e.input :question_id, as: :hidden, input_html: { :value => question.id } 
    <% end %> 
    <% end %> 
<% end %>
