That sort of worked, it returned an array of true, false values
corresponding to !c.selected. That did help me figure out the
solution though. Here's what worked:
@account.clients.map{ |c| !c.can_edit(@unit) ? c : nil }.compact
I didn't have a selected property, but I did have a can_edit(unit)
method that returns true or false. Clients that can_edit the @unit
are already on the list...
Only thing is, this runs a separate database query for each client for
the can_edit(@unit) call. Is there any way to do this in one query?
Thanks!
