问题描述：

我创建了一个类似 twiiter 的应用程序，朋友可以在其中发帖，但我想要在显示所有帖子的列表中包含创建帖子的人的姓名.

I created an twiiter like app, where friends can post, but i want a include the name of the person who created the post in the list showing all the post.

这是我的代码

class PostsController < ApplicationController
  def index
    @posts = Post.all(:order => "created_at DESC")

    respond_to do |format|
      format.html
    end
  end

  def create
    @post = Post.create(:message => params[:message])

    respond_to do |format|
      if @post.save
        format.html { redirect_to posts_path }
        format.js
      else
        flash[:notice] = "Message failed to save."
        format.html { redirect_to posts_path }
      end
    end
  end
end
`

答

当然假设设置了'user has many posts'关联，并且用户模型有一个'username'字段，你可以在你的观点:

Assuming, of course, that the 'user has many posts' association is set, and the user model has a 'username' field, you can do this in your view :

<% @posts.each do |post| %>
  <%= post.user.username %>
<% end %>
