Awesome refactoring

garbage.rb

@parent_ou = OrganizationalUnit.where("api_key='#{@api_key}' and api_secret='#{@api_secret}' and master_node=1")

#get first descendents of ou then find all of their children recursively
children = @parent_ou.first.children
ou_children = (children + children.map(&:children)).flatten

#put the children ouid's in a new array
@ous = Array.new
ou_children.each do |child|
  @ous.push child.id
end

refactored.rb

@parent_ou = OrganizationalUnit.where("api_key='#{@api_key}' and api_secret='#{@api_secret}' and master_node=1")

# remove any session data for this user in case of a corrupt session - we're going to set a new one anyway
CakeSession.delete_all(["id = ?", "#{@api_key}#{@api_secret}"])

#get list of all ou's in organization
lft = @parent_ou.first.lft
rght = @parent_ou.first.rght

@ous = OrganizationalUnit.where("lft >= ? and rght <= ?", lft, rght).map(&:id)
