ruby on rails 3 - ActiveRecord sort children within parent -

is there way pre-sort children of parent through activerecord (rails 3.2.13)?

so if have setup this

class parent < activerecord::base has_many :children  [...]  class children < activerecord::base belongs_to :parent

something like this:

p = parent.where(:name => 'diana').includes(:children, :order => 'd_o_b desc')

that way when call p.children getting array of objects ordered birth, , not database id.

or need sort array afterward?

in parent model, change has_many to:

has_many :children, :order => 'd_o_b desc'

then anytime access children association parent record (e.g., @parent.children), they'll in descending order of date of birth.
