Instance Method Details

#call(options) ⇒ Object

Accepts an existing (unsaved) :modality, or builds a new one from the options hash. Terminates an existing current modality if once exists, and saves and make the new modality current. Example usage:

 result = Modalities::ChangePatientModality
  .new(patient: patient, user: curret_user)
  .call(
     description: HD::ModalityDescription.first!,
     started_on: Time.zone.now
  )

or

modality = patient.modalities.new(
  description: HD::ModalityDescription.first!,
  started_on: Time.zone.now
)
result = Modalities::ChangePatientModality
  .new(patient: patient, user: curret_user)
  .call(modality: modality)
)

A Success or Failure result object is returned and the actual modality can be accessed on the result.object property.

We can broadcast events to inform listeners the modality has changed. See #broadcast_modality_change_event_to_any_listeners for configuration.
