================== import { Injectable } from '@angular/core'; import { AngularFireDatabase, AngularFireObject } from 'angularfire2/database'; import { User } from 'firebase/app'; import { Profile } from '../../models/profile/profile.interface'; import "rxjs/add/operator/take";

/* Generated class for the DataProvider provider.

See https://angular.io/guide/dependency-injection for more info on providers and Angular DI. */ @Injectable() export class DataServiceProvider {

profileObject: AngularFireObject

constructor(private database: AngularFireDatabase) { }

getProfile(user: User){ this.profileObject = this.database.object(/profiles/${user.uid}, { preserveSnapshot : true});

return this.profileObject.take(1);

}

async saveProfile(user: User, profile: Profile){ this.profileObject = this.database.object(/profiles/${user.uid})

try {
 await this.profileObject.set(profile);
 return true;
}
catch(e) {
  console.error(e);
  return false;
}

} }=========================
