includes(...) works great in most cases where you are using standard has_many and belongs_to. But we have a special referenced relationship that does not use this field and were wondering if it was possible to emulate something like includes using a different field.

We have something like:

#parents = Parent.all.includes(:children)
parents = Parent.all
parents.each do |p|
  p.children.each do |c|
    # N+1 query
  end
end

Seems like there should be some hack here to get the children in there with one query. Thanks!
