I actually ended up doing this which worked:
-- <% last_artist ||= nil %>
<table id="artist"> <tr> <th>Artist</th> <th></th> <th>Album</th> </tr> <% @pin_albums.each do |pin| %> <% if last_artist != pin.artist %> <tr> <td><%= pin.artist %></td> <td><%= link_to image_tag(pin.image), pin %></td> <td><%= link_to pin.album, copy_pin_path(pin) %></td> </tr> <% else %> <tr> <td></td> <td><%= link_to image_tag(pin.image), pin %></td> <td><%= link_to pin.album, copy_pin_path(pin) %></td> </tr> <% end %> <% last_artist = pin.artist %> <% end %>On Thu, Feb 19, 2015 at 2:45 PM, Hassan Schroeder <hassan.schroeder@gmail.com> wrote:

Hint: "scope"
2.1.0 (main):0 > 3.times{ puts (val ||= 0); val += 1 }
0
