consider
class Physician < ActiveRecord::Base
has_many :appointments
has_many :patients, through: :appointments
end
class Appointment < ActiveRecord::Base
belongs_to :physician
belongs_to :patient
end
class Patient < ActiveRecord::Base
has_many :appointments
has_many :physicians, through: :appointments
end
now if we define Physician#patients
as has_many :patients
(i.e. without the through) and then do this:
old_physician = Physician.find_by_name('Foo')
new_patient = Patient.new(name: 'new guy')
appt = Appointment.new(physician: old_physician, patient: new_patient)
we would find on the server that
new_patient.physicians
is [<Physician name: Foo>]
but on the client the list is empty. So it seems that Rails is inferring (or not even caring about) the missing inverse has_many though:
on Physician
(since we are not accessing it), but hyperstack is failing for some reason.
Of course if we can infer the relationship (per Rails) that is great, but at least there should be a warning or error so you can fix it.
