Question

in my client_controller.rb

def edit
  @client = Client.find(params[:id])
  @client.build_address unless @client.address
  ...
end

…address is nested polymorphic attribute (1:1)

I don’t like to call the build attribute in controller

my question:

is it good idea to automaticly build nested object if it isn’t build yet ?

example:

class Client
  has_one :address, :as => :addressable             #polymorphic
  #...

  def address
    super || build_address
  end
end

question2:

is there better way to do that ?

Answer 1

Implemented like that in project form more than 6 weeks, still no problem at all,

so yeah looks like a good idea in my case, see question comments
