Combine $FirebaseObject and multi location updates

问题

Is there a way to do a multi-location update when using a $FirebaseObject?

When i try it like this i get an error "Firebase.update failed: First argument contains an invalid key ($id) in property"

            var customerData = {};
            customerData["Customers/" + user.uid] = firebaseObject;
            customerData["ProjectOverview/" + user.uid] = "value";
            ref.update(customerData);

I could use the solution in this SO question but that doesn't seem like the best way to do this.

Is there a better way to do multi-location updates when using a $FirebaseObject?

回答1:

You can use $firebaseUtils.toJSON(), which AngularFire uses in its $save() method:

var customerData = {};
customerData["Customers/" + user.uid] = $firebaseUtils.toJSON(firebaseObject);
customerData["ProjectOverview/" + user.uid] = "value";
ref.update(customerData);
