foreign_key problems

model user id (automatic primary) fname lname user_rrid (foreign key) - string "123456"

model email id (automatic primary) e_addresss user_rrid (foreign key) - string "123456" e_type

i would like to find a user by fname @user = User.find_by_fname("John") then use... @user.email.e_address @user.email.e_type

i would also like to go the other way. search email based on e_address and find the user.

can you please show how the user.rb and email.rb files should be set up. i have looked thru the docs and googled and everything i try does not work. i have tried using foreign_key but it does not work. thanks.
