Rails - Jul 2006 - Grouping arrays in the View

I remember reading something awhile back about an easy way to work with
object arrays in views.  Say I want to arrange 20 images objects in rows
of 3.  I have a collection of @users, where each user has a
user.thumbnail_url image.  Is there some way to split these up so that
they can be easily parsed in rows of three?

 

 

Thanks,

Nathan

I think your best option would to make a helper for it.  Make one helper
that accepts the entire array and breaks it up into chunks of three, which
passes it to another helper that actually displays the 3 images for you.

If the problem is getting the actual data out, array has a method called
collect which can be used to call the same method on multiple objects in an
array, so you could do something like @users.collect{|user|
user.thumbnail_url}  That will give you an array of all of their image urls.
