Q:

How to display paperclip's uploads. 

Im currently building a blog.  While the paperclip photos pop up inside the individual blog posts they don't seem to pop up in the index, where all the blog posts are displayed.  
13th line seems to be the problem.  
this is my index.html.erb for my posts
10   <% @posts.each do |post| %>
11       <tr>
12       <td><%= link_to  post.title, post_path(post) %></td>
13       <td><%= image_tag @post.picture(:medium) %></td>
14       <td><%= post.text %></td>
15       <td><%= link_to 'Show', action: :show, id: post.id %></td>
16       <td><%= link_to 'Edit', action: :edit, id: post.id %></td>
17       <td><%= link_to 'Destroy', { action: :destroy, id: post.id },
18                       method: :delete, data: { confirm: 'Are you sure?' } % ></td>

it throws me a no method error. 
Please let me know if I can give you extra files if you need more information
Thank you in advance! 

A:

You're not passing the URL for the image to the image_tag helper. 
You need to display your image like this:
<%= image_tag post.picture.url(:medium) %>
