== README Run:

rake db:setup

Open a rails console, and create 2 users:

User.create(:name => 'Donald Trump', :meta_type => 'Doctor')

User.create(:name => 'Jerry Springer', :meta_type => 'Patient')

Then try creating a join table between them:

Doctor.first.patients << Patient.last

This creates a join table between the doctor and patient, but there are two problems:

1. The provider_type is set to User, (because of the class name set in patient_provider_relation.rb). How would I set it to be the class_name of the provider type (e.g. Doctor, Nurse etc)?

2. If I then do Patient.first.providers, I get a

   NameError: uninitialized constant Patient::Provider
