How can I find a model's relationships?

Question

I want to, when given a particular model, return all the related models it is associated with. For example:

class Dog < ActiveRecord::Base
  has_many :bo         


        

Answer 1

Dog.reflect_on_all_associations

You wouldn't do this on an instance but on the model itself.
