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

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