博客及其作者和评论者[如何使它们出现]

Question

我有3个模型user has many articles，user has many comments，articles belongs to user，comments belongs to user，如何让用户的名字出现在评论或文章中张贴？

<%= div_for comment do %>
  <p><strong><%=  %> says</strong></p> # how should i write a condition here to make the name of the commenter appear when he puts a comment
  <%= simple_format comment.content %>
<% end %>

Answer 1

您应该添加一个Comment也属于User。

然后：<%= comment.user.name %>（如果用户模型具有name属性）
