Adding property in Observable data before returning through connect function of angular material
I am using angular material table.Inside connect function I am returning an observable of type patient. But I have to update the value of patientData observable before returning .I have to add a "Active property if the patient id exist in redrows array.
connect function of data table
connect(): Observable<Patient> {
const patientData = this.patientService.getPatient();
patientData.subscribe((jsonData) => {
const redRows = this.getAge(jsonData);
for (let a = 0; a < jsonData.length; a++) {
if (redRows.includes(jsonData[a].id)) {
jsonData[a].active = 'Active';
} else {
jsonData[a].active = 'Not Active';
}
}
return jsonData;
},
(err) => console.error(err),
() => console.log('observable complete'));
return patientData;
}

Modifying data and returning from subscription
won't change the observable, don't subscribe()
in connect()
. Use map operator from rxjs
to modify data.
import { map} from "rxjs/operators"
connect(): Observable<Patient> {
return this.patientService.getPatient().pipe(
map((jsonData) => {
const redRows = this.getAge(jsonData);
for (let a = 0; a < jsonData.length; a++) {
if (redRows.includes(jsonData[a].id)) {
jsonData[a].active = 'Active';
} else {
jsonData[a].active = 'Not Active';
}
}
return jsonData;
})
)
}
subscribe
to connect()
wherever you are using it.
thank you so much.It worked.
