Question

I have the following models:

class Ad < ActiveRecord::Base
  belongs_to :page

  has_one :image
  has_one :logo
end

class Page < ActiveRecord::Base
           


        

Answer 1

Check your test database.

In my case, sometimes I did not modify the columns in the test database after modifying the development database after an incorrect migration.
