i created one model called team so a migration is created and i
edited the migration like this

class CreateTeams < ActiveRecord::Migration
def self.up
create_table :teams do |t|
t.string :country
t.string :group
t.string :captain

  t.timestamps
end

end

def self.down
drop_table :teams
end
end

when i tried to rake

i am getting an issue like this

mathew@mathew mux]$ rake db:migrate
(in /home/mathew/user/mux)
rake aborted!
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.size

(See full trace by running task with --trace)

your problem lies in the controller file and not in the migration one.
please post the controller file for evaluation.
