在评论返回问题:: ActiveRecord_Associations_Collection [英] Returning issue in Comment::ActiveRecord_Associations_Collection
问题描述
我想显示所有来自用户在用户个人资料页面提出的意见（不管它是公共或登录后面的页面），但我遇到打印在我的应用程序注释的问题： ：ActiveRecord_Associations_CollectionProxy：0x00000103c89750（这不是杀死我的应用程序错误，只是打印该消息）
I'm trying to display all the comments made from a user in a User profile page (no matter if it's a public or a page behind the login), but I'm experiencing an issue that prints in my app Comment::ActiveRecord_Associations_CollectionProxy:0x00000103c89750 (it's not an error that kills my app, just prints that message).
在我的应用程序的唯一元素commentable是黑客，并且用户可以创建每个黑客意见。
the only element commentable within my app are 'hacks', and users can create comments on each hack.

用户视图
<p>
<strong>User email?:</strong>
<%= @user.email %>
<%= @user.comcoms %>
</p>
我用征求意见的宝石The_Comments，有的一些文档在这里，我还要广泛阅读，我认为的 @ user.comcoms 应该回到我在寻找什么，而不是：/
The gem I'm using for comments is The_Comments and there are some docs here that I have read widely, and I think @user.comcoms should return what I'm looking for but not :/
推荐答案
@ user.comcoms 将给予相关的特定用户的所有评论（ @user 你的情况）commentable模型。因此，它会返回一个意见收集和评论:: ActiveRecord_Associations_CollectionProxy：0x00000103c89750 是显示该集合的参考
@user.comcoms will give all comments related to the particular users(@user in your case) commentable models. So, its going to return a collection of comments and Comment::ActiveRecord_Associations_CollectionProxy:0x00000103c89750 is showing the reference of that collection.
您需要遍历集合并从注释实例显示所需要的领域类。
You need to iterate over the collection and display the required fields from an instance of Comment class.
替换
<%= @user.comcoms %>
通过
<% @user.comcoms.each do |comment| %>
<%= comment.raw_content %>
<%= comment.commentable_title %>
<%# Add other attributes %>
<% end %>
