This is my setup. I have a table user where all user with password and so on are set. The customer table has some customer related data. The user_id is the foreign key to relate the customers to the user.
On of the column in the customer table is the customernumber. These numbers has to be uniq for each user_id. class Customers > belongs_to :user > end > > class Users > has_many :customers > end For example. customer | customernumber | user_id 1 0001 1 2 0002 1 3 0001 2 4 0001 3 5 0002 3 How can i approach this? Any hints what I have to look for? thanks in advance best regards denym -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
