Ruby on Rails: 显示页面显示错误

Question

这是我的show.html.erb

<h1> <%= @category.name %> </h1>
<ul>
<%= @category.soups.each do |soup| %>
<li> 
    <%= link_to soup.name , soup %> 
</li>
<% end %>
</ul>
<p> <%= link_to "back", categories_path %></p>

然而，这是结果。

为什么显示

[#<Soup id: 1, name: "Tonkotsu", featured: true, category_id: 1, created_at: "2015-07-22 11:30:37", updated_at: "2015-07-22 16:59:20">, #<Soup id: 4, name: "Beef Flavor", featured: nil, category_id: 1, created_at: "2015-07-22 17:03:34", updated_at: "2015-07-22 17:10:36">]

Answer 1

更改此行

<%= @category.soups.each do |soup| %>

到

<% @category.soups.each do |soup| %>

<% %> -----> 执行语句。
<%= %> ----> 打印输出。

Answer 2

您在遍历 @category 的汤时添加了“=”符号。这样做

<ul>
  <% @category.soups.each do |soup| %>
    <li> 
        <%= link_to soup.name , soup %> 
    </li>
  <% end %>
</ul>
