TypeError: ref.key is not a function

AngularJS: v1.5.11 Firebase: v3.6.9 Angularfire: v2.3.0

I want to get the key. After creating the JSON object my code : 

  }).then(function(ref){
          var id = ref.key();
          console.log("Added User with ID: "+id);

The value is inserted in the firebase DB but getting this error and nothing is shown in the console log.

I guess the syntax to get the key is changed with these versions. I don't know what the ref.key() is used for really. Is it required as to set some primary key?

Solution

  • Reference.key() used to be a function in Firebase JavaScript SDK 2.x. But is is now a read-only property, so you should use ref.key.

    This and many more things to be aware of when upgrading your code are covered in the Firebase migration guide for web developers: https://firebase.google.com/support/guides/firebase-web
