Stuck at deleting parent pushed key by value/childkey

Question

I want to delete a parent pushed key by value/childkey:

export class FaqsPage {
  qS: Observable;
  ques = \'\';
  ans = \'\';

constructor(priva         


        

Answer 1

I hope you are using angularfire2

this.qS = this.db.list('table/faq').snapshotChanges().map(changes => {
  return changes.map(c => ({ key: c.payload.key, ...c.payload.val() }));
});

this will return the qS with key
