不明な属性 `html`を書き込めませんテンプレートインクルージョンのトレース

Question

私のROR APPに奇妙なエラーが発生しました。 _form.html.erbファイルが添付されています。これは、ブラウザが私のエラーであると言うからです。私は初心者ですので、私はこの事例で間違っています。ありがとう！ここ

<div class="panel panel-default"> 
    <div class="panel-heading"> 
    <div class="panel-title"> 
<h1>New Review</h1> 
</div> 

<%= form_for(@lawfirm, @review) do |f| %> 
    <% if @review.errors.any? %> 
    <div id="error_explanation"> 
     <h2><%= pluralize(@review.errors.count, "error") %> prohibited this review from being saved:</h2> 

     <ul> 
     <% @review.errors.full_messages.each do |message| %> 
     <li><%= message %></li> 
     <% end %> 
     </ul> 

    </div> 
    <% end %> 

    <div class="form-group"> 
    <%= f.label :rating %> 
    <%= f.number_field :rating, class: "form-control" %> 
    </div> 
    <div class="form-group"> 
    <%= f.label :comment %> 
    <%= f.text_area :comment, class: "form-control" %> 
    </div> 
    <div class="form-group"> 
    <%= f.submit class: "btn btn-primary"%> 
    </div> 
    </div> 
<% end %> 

    </div> 
</div>

Parameters: 

{"lawfirm_id"=>"1"} 

Answer 1

問題はここにあるかもしれない：

form_for(@lawfirm, @review) 

形でネストされたリソースのための適切な構文は次のとおりです。

form_for([@lawfirm, @review]) 

form_forは、 e最初の引数がリソース（この場合はネストされたリソース）になります。 2番目の引数は、サポートされているオプションキーの1つであるhtmlのオプションのハッシュです。これは、スタックのエラーを引き起こしている可能性があります。
