Hi,
i am stuck, this is my code:
rails generate migration add_first_name_and_last_name_to_contacts :contacts first_name:string last_name:string
The error message says that the first argument has to be the table name, so contacts is the table name and the first argument. I am not really sure what the problem is.
Thank you in advance!
Regards, Sebastian

rails generate migration add_first_name_and_last_name_to_contacts first_name:string last_name:string
When you create the table you include the table name as a first argument in the list after the migration name, but when changing tables you don't.

Courses Plus Student 39,959 PointsI tried with this:
rails generate migration CreateContacts first_name:string last_name:string
and it generates this migration which is identical to the one on the previous challenge:
class CreateContacts < ActiveRecord::Migration
def change
create_table :contacts do |t|
t.string :first_name
t.string :last_name
end
end
end
.... but it doesn't works
