Database and model design for multiple user roles

I would like to create a web application that has two types of users,
producer and consumer.
Both users have three fields in common : username,password and email.
Producer has also the fields address and telephone.
I could make separate models,views,controller and tables for each user
types but this violates DRY. Could Single table inheritance be used and how?
