FuelPHP Forums

This may be a silly or noobish question (I have much deeper to go in my mastery of OOP) and if so, apologies! I have a Model_User, mapped to the users table in my db. However, my application has three types of users - artists, voters and volunteers. Some of the fields in the users table apply to all three and some only apply to one. What I'd like to do is extend my Model_User with subclasses for each user type - Model_Artist, Model_Voter, Model_Volunteer. Each of the user subclasses would have $_properties from the users table that pertain only to that type. The Model_User would have $_properties that pertain to all three. My question is basically is this ok with Fuel's ORM? Will this work or will it completely break the db mapping? If the latter, how can I best implement this sort of division between my various user types? Thanks very much for any help!
