Order records based on number of children
Let''s say I have simple schema with two tables. The models are defined
like the folllowing:
class Parent < ActiveRecord::Base
has_many :children
end
class Child < ActiveRecord::Base
belongs_to :parent
end
Simple has_many relationship. Is there any way to order the results of
a Parent.find_all by the number of children the parent has? I can
sort with
sorted_parents =
