rake db:migrate

Hi, I'm new to Rails. Does rake db:migrate only process things under your /db/migrate/ folder? I made some changes in my /app/models/ files such as defining relationships between classes, but this doesn't seem to be reflected in my underlying database. So how do I create foreign keys in Rails without doing it manually in my DBMS?

Thanks.

You don't. You create migrations that add those columns, keys etc...
