Pointer on resources' properties?

[benji-bou]

Hello,

Thanks for this nice package.
I was wondering why is there pointer on each generated resources' properties?

My objective here is to read fhir data from a bigquery. But the type mapping is not possible because of properties generated with pointer
I know this is not the purpose of this package to let us map fhir data from bigquery.

For example :

func (r Request) EncounteredPatients(practitionerId string) ([]fhir.Patient, error) {
	it, err := r.Raw(fmt.Sprintf(`SELECT * 
		FROM <gcp_project_id>.<bigquery_datasets>.Patient patient 
		INNER  JOIN (
			SELECT DISTINCT subject.patientId  
			FROM bios-innov.metamedical.Encounter as encounter, UNNEST(encounter.participant) as participant  
			WHERE participant.individual.practitionerId = '%v') encounters  
		ON patient.id = encounters.PatientId`, practitionerId))
	if err != nil {
		return []fhir.Patient{}, fmt.Errorf("EncounteredPatients failed for %v: %w", practitionerId, err)
	}
	patients := make([]fhir.Patient, 0, 0)
	for {
		var patient fhir.Patient

		err := it.Next(&patient)
		if err == iterator.Done {
			break
		}
		if err != nil {
			return patients, fmt.Errorf("Failed to read result : %w", err) // TODO: Handle error.
		}
		// fmt.Println(row)
		patients = append(patients, patient)
	}
	return patients, nil
}

Will lead to an error bigquery: schema field active of type BOOLEAN is not assignable to struct field Active of type *bool

But doing this

func (r Request) EncounteredPatients(practitionerId string) ([]fhir.Patient, error) {
	it, err := r.Raw(fmt.Sprintf(`SELECT * 
		FROM <gcp_project_id>.<bigquery_datasets>.Patient patient 
		INNER  JOIN (
			SELECT DISTINCT subject.patientId  
			FROM bios-innov.metamedical.Encounter as encounter, UNNEST(encounter.participant) as participant  
			WHERE participant.individual.practitionerId = '%v') encounters  
		ON patient.id = encounters.PatientId`, practitionerId))
	if err != nil {
		return []fhir.Patient{}, fmt.Errorf("EncounteredPatients failed for %v: %w", practitionerId, err)
	}
	patients := make([]fhir.Patient, 0, 0)
	for {
		var patient fhir.Patient
		var row map[string]bigquery.Value
		err := it.Next(&row)
		if err == iterator.Done {
			break
		}
		if err != nil {
			return patients, fmt.Errorf("Failed to read result : %w", err) // TODO: Handle error.
		}
		jsonRaw, errJson := json.Marshal(row)
		if errJson != nil {
			return patients, fmt.Errorf("Failed to marshal result : %w", errJson)
		}
		errReDecode := json.Unmarshal(jsonRaw, &patient)
		if errReDecode != nil {
			return patients, fmt.Errorf("Failed to Unmarshal result : %w", errReDecode)
		}
		// fmt.Println(row)
		patients = append(patients, patient)
	}
	return patients, nil
}

Will succeed.
