How can a table automatically create a column? If you have profile
belongs_to state then you have to create a migration to put the
state_id column in the database. I think you need to follow the
advice that has now nearly worn out my keyboard, so many times have I
typed it: You should work right through a good tutorial such as
railstutorial.org (which is free to use online). That will show you
the basics of Rails.

What has the categories table got to do with it? I thought this
problem is about profiles and states.
