How to update firebase

Question

I am using ionic 2.

I need update data into firebase using Firebase 3

Here is my code.

import firebase from 'firebase'; up() { var v=this.Editflat.value; firebase.database().ref('/flats').update(this.key,v).then(res=> {console.log("UPDATED",res)}); }

I am getting this error

Error: Firebase.update failed: First argument must be an object containing the children to replace.

How can I fix this issue?

Kindly advice me,

Thanks.

I presume this is what you want:

var v = this.Editflat.value; firebase.database().ref('/flats/' + this.key).update(v).then(res => { console.log("UPDATED",res) });

The variable v should be an Object. You can read more about it here.

I don't understand your question. Do you mean the page redirects without updating the Firebase data? You must post more code and edit your question details.
