我想寫一個新的評論嵌套在resturants，但我不斷收到評論＃新行動沒有方法錯誤。我不斷收到一條紅線評論形式NoMethodError in評論＃新
<%= form_with(model: [@review, @resturant] , local: true) do |form| %>
完整的錯誤消息：
NoMethodError in Reviews#new Showing /Users/AHmed/Desktop/burgerland-ar/app/views/reviews/_form.html.erb其中線＃1提出：
undefined method `review_resturant_path' for #<#<Class:0x007f8b3abe3170>:0x007f8b3abe04e8> Did you mean? resturant_reviews_path resturant_review_path new_resturant_path
做了新軌道5語法改變或錯誤與評論控制器？這裏是我的代碼：
評論/ _form.html.erb
<%= form_with(model: [@review, @resturant] , local: true) do |form| %>
<% 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="field">
<%= form.label :rating %>
