Retrieve Individual Item using db.object in AngularFire2: Delayed Data Retrieval

Currently, I am using Angular4 (4.3.6) in combination with AngularFire2 (4.0.0-rc.2). To retrieve data for a detailed view, I use the following code:

// GET THE ID
this.id = this.route.snapshot.params['id'];

this.subscriptions.push(
  this.db.object('/restaurants/' + this.id).subscribe(data => {
    this.restaurant = data;
    console.log(data);
  })
);

Although this approach fetches the data needed, it results in errors being thrown in the console due to the data arriving slightly delayed. Additionally, I prefer not to obtain the id from route.params as I plan to use the object name as a route for the detail view at a later stage.

Answer №1

If you want to customize keys while creating items, you can follow this approach: path = restaurants/${res_name}

createCustomItem(res_name: string, data_1: string, data_2: string) {
const path = `restaurants/${res_name}`; // Firebase endpoint
const userReference: AngularFireObject<any> = this.db.object(path);
const itemData = {
  restaurantName: res_name,
  someData: data_1,
  moreData: data_2
};
userReference.update(itemData)
  .catch(error => console.log(error);

}
