Question

I have created a complex object in rails with a principle parent object “Resume” it has a number of child objects for each section(“objective_section”, “contact_section”, etc), is there a way I can fetch all associated objects to the parent object Resume?

Answer 1

If by fetch you mean load from the database all in one query, then sure:

Resume.first(:include => [:objective_sections, :contact_sections]) # etc...

If this is a common pattern and you want to DRY things up without much effort, you can throw this into a named_scope in your model:

class Resume < ActiveRecord::Base
  has_many :objective_sections
  has_many :contact_sections

  named_scope :with_sections, :include => [:objective_sections, :contact_sections]
end
