Question

I’m just getting rolling with RoR so I’m sure this is pretty basic. Let’s say I have two models: Account and Transaction

class Account < ActiveRecord::Base     has_many :transactions end  class Transaction < ActiveRecord::Base     belongs_to :account end 

What methods (for each model) become available/are auto generated after I make this association?

Thanks

Answer 1

It depends. Some methods (e.g. Account#transactions, Transaction#account) will be there from the get-go. Others will be created as needed (via a method_missing hook) such as dynamic finders. The exact list can depend on other factors, including things like acts_as, etc. used elsewhere.

Are you concerned about which ones are created or about what the full possibilities are?
