# The problem I have is that I've got a sort_code field in the database, and I want to keep that as one field
# BUT I want users to edit it in the form using 3 different fields.

# My initial solution was to use virtual attributes and divide it this way. 
# Can you think of a better way?

banana = Banana.new
banana.valid? #=> true

banana.singleton_class.validates_presence_of :name
banana.valid? #=> true - why did the validation not work?  

banana.class.validates_presence_of :name
banana.valid? #=> false - as we'd expect...but now...
