Hi all, please pardon my question if it seems silly.. I'm trying pretty hard to learn though. :) I have 2 tables: feeds (has_many feed_items) feed_items (belongs_to feed) Let's say Feeds has 3 feed.names: "Things that Start with A", "Things that start with B", "Things that start with C". I want to print out, on one page, something like the following: Things that start with A Apples Angels Acrobats Things that start with B Books Bottles Bears Things that start with C Cats Cars Cocoons I figured out how to do this in a loop in the view, i.e. Controller: def index @feeds = Feed.find(:all) end View: <% for feed in @feeds %> <h3><%=h feed.name %></h3> <% for feeditem in feed.feed_items %> <%=h feeditem.name %> <% end # end feeditem loop %> <% end # end @feeds loop %> Is this bad style? Should I be pulling this data somehow in the controller instead? I know it doesn't really matter for a simple example, but I plan to make a fairly complex app (not insane, but a few dozen views by the time it's done), and I'd like to do it correctly from the beginning. :) Someone in IRC suggested, in the controller, def index @feeds = Feed.find(:all) @feeditems = FeedItem.find(:all) end But then, of course, you get the entire list (A, B, and C) for each feed.. so that's not quite right. Any comments/suggestions appreciated.
