Question

我正在为我的一个班级创建一个测试鞋店网站。我之前为新鞋添加了评论部分和评级系统。由于某种原因，评论和评级部分不再可见。

这是我的产品展示页

   <p id="notice"><%= notice %></p>
    <div class="show-buttons" id="show1">
    <%= link_to 'Edit', edit_product_path(@product), class: "btn btn-    success btn-xs"  %> |

    <%= link_to 'Back', products_path, class: "btn btn-primary btn-xs" %>
  </div>
  <div class="pay button">
  <%= form_tag "/payments/create" do %>
  <%= render partial: "shared/stripe_checkout_button" %>
  <%= hidden_field_tag(:product_id, @product.id) %>
</div>
<p>
  <strong>Name:</strong>
  <%= @product.name %>
</p>

<p>
  <strong>Description:</strong>
  <%= @product.description %>
</p>

<p>
  <strong>Image url:</strong>
  <%= @product.image_url %>
</p>

<p>Average Rating: 
  <div class="rated" data-score="<%= @product.average_rating %>"></div> 
</p>

<%= render 'new_comment' %>
    <%= render 'comment' %>
    <%= will_paginate @comments %>  

</div>


<% end %>

这是我的_comment.html.erb

<div class="container">
    <div class="row">
        <div class="product-reviews">
        <% @comments.each do |comment| %>
        <div class="row">
            <hr>
          <p><%= comment.user.first_name %> <small><em><%= "# {time_ago_in_words(comment.created_at)} ago" %></em></small></p>
        <% if signed_in? && current_user.admin? %>
            <%= link_to ('<span class="glyphicon glyphicon-remove">  </span>').html_safe, product_comment_path(@product, comment), method: :delete, data: { confirm: 'Are you sure?' } %>
        <% end %>   
        <div class="rated" data-score="<%= comment.rating %>"></div>
        <p><%= "Rating: #{comment.rating}/5" %></p>
        <p><%= comment.body %></p>
    </div>
    <% end %>
    </div>
</div>

我的_new_comment.html.erb

<% if signed_in? %>
  <h4>Add a review:</h4>
  <%= form_for([@product, @product.comments.build]) do |f| %>
    <p>
  <%= f.label :body, "Comments" %><br>
  <%= f.text_area :body %>
</p>
<p>
 <%= f.label :rating %><br>
  <div class= "rating"></div>
</p>
<%= f.submit "Submit", class: "btn btn-default" %>    
</p>
  <% end %>
<% end %>

最后我的product.html.erb

<div class="container">

  <div class="row">
    <div class="col-md-4">

     <div class="productbox">

        <div class="imgthumb img-responsive">
          <%= image_tag(product.image_url, :class => 'list_image') %>
        </div>
        <div class="caption">
          <h3><%= product.name %></h3>   
        </div>

      </div><!--end productbox-->
      </div><!--end columns-->

         <div class="col-md-8" id="descriptionp">
          <p><%= product.description %><br><br>
          <%= product.color %><br><br>
          €<%= product.price %><br><br>
          <%= link_to 'More Info', product %><br><br>

          <% if signed_in? && current_user.admin? %>
          <%= link_to 'Edit', edit_product_path(product) %> | 
          <%= link_to 'Destroy', product, method: :delete, data: { confirm: 'Are you sure?' } %>
          <% end %>
         </p>
         </div>    
  </div><!--/row-->  
</div><!--/container -->
<hr>

对于我无法再查看我的评论或评级页面的任何帮助将不胜感激。
