Hi there,

I have a one to many relationship between a restaurant and menus. In my view I want to iterate through each of the menu's belonging to a given restaurant. I also need to distinguish between the first one in the list and the rest of them.

What is the best control structure/ method for accomplishing this? Assume I have @restaurant.menus to get the list

thanks, steve

feels like a case of

<% @restaurant.menus.each_with_index |menu, index| %>   * do stuff for all the menus - call a partial probably *   <% if index == 0 %>     * do special stuff for the first one *   <% else %>     * for stuff for the others *   <% end %> <% end %>

That's yucky!

I'd see the use of Array#shift rather than have the conditional code
executing on every iteration.

<% @menus = @restaurant.menus; @menu = @menus.shift %>

<%# do stuff for the first menu %>

<% for @menu in @menus %>

<%# do stuff for others %>

<% end %>
