I want to generate a table of images, something like:
<I> <I> <I>
<I> <I> <I>
So I've to put a <br> after 3 iterations, how should I do this?
I could make a counter initialize it on zero, increment its value and
check it for "mod3=0", but I think there might be a better way to do
it
in ruby?
I've something like:
<% @games.each do |game| %>
<%= link_to image_tag(game.image.url), game %>
<% end %>
Couple of options... you could do each_with_index and then print a
<br> if i % 3 == 0. You might not get a <br> on the last line though.
Or you could use in_groups_of which is meant for this sort of thing.
