Rails Migrating Foreign Keys -

i have discovered relationship between 2 of tables wrong , make necessary changes - involves dropping foreign key on accommodations table , adding foreign key on users table.

i have created migration file using:

rails g migration foreignkeyadjustment 

and added new migration file:

class foreignkeyadjustment < activerecord::migration   def self.up     remove_column :accommodations, :user_id     add_column :users, :accommodation_id, :integer   end end 

i ran migration using:

bundle exec rake db:migrate 

and used console check column names in each table , changes have not taken effect!

rails console 

and

user.column_names 

what missing?

p.s. major issue if deleted models , database migration files , generated new models terminal? wouldn't take me long , no important data consider.

have established active record associations? allow map records 1 table another. otherwise column name arbitrary name in table.

did add foreign key attribute model? creates attribute existing model through in attr accessible

these can of potential problems
