Ruby on Rails: User model association applications and migrations

I'm still fairly new to Ruby on Rails and I'm working with associations, such as if a table has_many :facts, or belongs_to :list,

do we deal with users as well? for Users model:

has_many :lists

and then the list model should have

belongs_to :user

Now does this mean I need to create a new column in the table? Right now I only have email and password_digest. Do I need to add a new migration to add a new column list_id. I already did rake db:migrate. Can I just simply add a column in the migration file?

Thanks

Yes, you must create a new column and if you already run the migration you must create a new one.

However, it's the list that must have the user_id.
