Question: Does sequelize-typescript support typed returns based on included associations? #1745
Description
For example, I have an appointments model and a patient model. The appointment model has a patientId. Is there a way to define the types so that:
appointment.findByPk(appointmentId, {include: [{model: db.patient}]});
results in a return type that includes the patient object on it? And vice-versa, if I don't include the patient model, can I get a return type where the patient object is not defined? I have the associations defined with decorators on the appointment class but it seems to always assume that patient will be present on the appointment object.

I find myself in the same position, it would be very useful if
appointmentwas a property of aPatient<Appointment>type but notPatientfor example, not sure if this is even possible with TypeScript.@ccmetz If this helps you at all, in the meantime you can resort to calling getters - these should resolve from memory if associated model was included, but will also lazy load if it wasn't, guaranteeing that the associated model will be resolved,
