My code:
class User < ActiveRecord::Base
belongs_to :university
end
class University < ActiveRecord::Base
has_many :users, dependent: :destroy
end
and my model User has a university_id attribute.
If I do University.find(1).users
I get the list of users, but if I do User.find(1).university
(and I checked that university_id is not nil here) I get:
NoMethodError: undefined method `university' for

What am I doing wrong? I have another models and they are working just fine. Any suggestions? Thanks in advance
