I have a child relationship that is denormalized. I want to normalize
it at the object level once it's retrieved:
class Parent
has_many :denormalized_children, :class_name=>'Child'
def children
if @normalized_children.nil?
@normalized_children = []
denormalized_children.group_by(&:number).each { |c|
@normalized_children << NormalizedChild.new(c)
}
end
@normalized_children
end
end
This works fine, but I don't want to eager load them
as :denormalized_children. I'd like to use :children. So I tried:
class Parent
has_many :children
alias :denormalized_children :children
def children
#Same definition
end
end
AR doesn't like this as it expects the children prop to return
something that responds to loaded.
has_many :children, :group=>'number'
doesnt work either since it discards all but N unique numbers. So if
I have 10 with number 1 and 5 with number 2 I'll only get back 2
children.
Is there any way to do this without having to change the name of the
relationship?
I can't use after_load (or whatever it's called) in the Child class
since the children need to be grouped by their relationship to their
parent.
Any suggestions would be great.
Thanks
