Question

I have something like this in the controller:

@puzzleGames = Game.where("category = 'puzzle'").limit(8)

but in the view I display them in 2 seperate areas, 4 in one and 4 in the other.

Instead of doing something like this:

<% @puzzleGames.each do |puzzleGame| %>

to loop through all elements, is it possible to loop to and from a finite number (0-3,4-7)?

Thanks

Answer 1

You can also try with this

@gameSlices = @puzzleGames.each_slice(4)

Then use @gameSlices.first and @gameSlices.last

EDIT: Just turned out that @gameSlices.next can be very useful in this case. It will return each slice one by one.

or you can use a block like

@puzzleGames.each_slice(4) do |slice|
    # Do your stuffs with slice
end
