Question

I’ve been running into issues while dealing with ember-data related to immutable arrays like for example “Uncaught Error: The result of a server query is immutable. ” This is what I got when i tried to apply removeObjects() method on a filtered list of array.

So, I’d like to know the difference & if possible how to convert them to the other

Answer 1

An immutable array just means that it can’t be altered directly (as opposed to a mutable array which can be changed).

According to Ember Data documentation, deleting records should be done like this:

To delete a record, call its deleteRecord() method:

var person = App.store.find(App.Person, 1); 
person.deleteRecord(); 

The record will not be deleted in the persistence layer until the store’s
commit() method is called. However, deleted records will immediately
be removed from its ModelArray and associations.

If that’s not helpful, could you write a jsfiddle?
