Question

I have the following listing:

<% @backgrounds.each do |background| %>
 <tr>
   <td><%= background.image.url %></td>
   <td><%= link_to 'Show', background %></td>
   <td><%= link_to 'Edit', edit_background_path(background) %></td>
 </tr>
<% end %>

I am trying to reuse this with other controllers. This is what I have so far:

<%= render partial:'image_listing', locals:{images:@backgrounds} %>

<% images.each do |image| %>
  <tr>
    <td><%= image.image.url %></td>
    <td><%= link_to 'Show', image %></td>
    <td><%= link_to 'Edit', edit_image_path(image) %></td>
  </tr>
<% end %>

Is there a more generic version of edit_image_path?

Answer 1

<%= render partial: "background", :collection => @backgrounds %>

# _background.html.erb
<tr>
  <td><%= background.image.url %></td>
  <td><%= link_to 'Show', background %></td>
  <td><%= link_to 'Edit', edit_background_path(background) %></td>
</tr>

If you call the partial with the same name of the object you want to iterate, the shortest form is

<%= render @backgrounds %>

If you can’t follow this convention, use :collection and :partial options to instruct the rendering.
