Rails ActiveRecord associations

Question

I have an User model.

How I can get all associations between the User model with other models ?

I need to know the model names and the association type (1..1, 1..m, m..m ...)

I don't want to use the db/schema.rb file

Answer 1

Use reflect_on_all_associations class method on the User model.

This will return an array of reflection objects. On those objects you can call macro method to find out the association type (:has_many, :belongs_to, etc.), and klass method to know the, em, class of the associated object(s).
