Question

我正在使用Paperclip进行多张图片上传。上传的图片显示在我的@post视图中：

  <% for asset in @post.assets %>
    <%= link_to image_tag(asset.image.url(:thumb)), asset.image.url(:big), :class => "fancybox", :rel => "gallery" if asset.image? %>
  <% end %>

我的问题是我希望这些图片也能在另一个视图中显示，如下所示：

  <% for asset in @post.assets %>
    <%= image_tag asset.image.url(:thumb) if asset.image? %>
  <% end %>

查看控制器：

class HomeController < ApplicationController
  def school_news
    @posts = Post.page(params[:page]).per(4).order('posts.id DESC')
  end
end

现在我有这个错误：

 NoMethodError in Home#school_news

Showing D:/Projects/livu_pamatskola/app/views/home/school_news.html.erb where line #17 raised:

undefined method `assets' for nil:NilClass

Extracted source (around line #17):

14:             <%= link_to 'Lasīt vairāk...', posts %> 
15:         </div>
16:     </div>
17:   <% for asset in @post.assets %>
18:     <%= image_tag asset.image.url(:thumb) if asset.image? %>
19:   <% end %>
20:     <div id="separator"></div>

我做错了什么？
