I can explain why you're getting this error. validates_as_phone is a
method. All methods in Ruby have a receiver object. Because
validates_as_phone is called outside of a defined method, it's
receiver object is the User class itself, *not* an object of type
User. The arguments that you pass to the validates_as_phone method
include a call to the is_client? method. Since the receiver object is
the User class, it looks for a method called is_client? defined for
the User class, which would look like this:
def User.is_client?
user_type_id == 2
end
or another way to say the same thing is:
def self.is_client?
user_type_id == 2
end
Instead, it finds a method defined for User objects:
def is_client?
user_type_id == 2
end
Unfortunately, you can't just stick a self. onto your is_client?
method because user_type_id is a method that belongs to User objects,
not the User class itself.
