Ruby on rails 在Comment:：ActiveRecord\u Associations\u集合中返回问题

我正在尝试在用户配置文件页面中显示用户的所有评论，无论是公开的还是登录后的页面，但我遇到了一个问题，该问题会在我的应用程序Comment:：ActiveRecord\u Associations\u CollectionProxy:0x0000103C89750中打印。这不是导致我的应用程序失败的错误，只是打印该消息

我的应用程序中唯一可以评论的元素是“黑客”，用户可以在每次黑客攻击中创建评论

用户视图

            <p>
              <strong>User email?:</strong>
              <%= @user.email %>
              <%= @user.comcoms %>
            </p>

我用于评论的gem是_评论，这里有我已经广泛阅读的内容，我认为应该返回我正在寻找的内容，但不是：/

@user.com将给出与特定内容相关的所有评论users@user在您的例子中，可注释模型。因此，它将返回一个注释集合，Comment:：ActiveRecord_Associations_CollectionProxy:0x0000103C89750显示该集合的引用

您需要迭代集合并显示Comment类实例中的必需字段

替换

<%= @user.comcoms %>

与

请参阅您在问题中添加的链接，以了解可在注释中访问的属性

 <% @user.comcoms.each do |comment| %>
    <%= comment.raw_content %>
    <%= comment.commentable_title %>
    <%# Add other attributes %>
 <% end %>
