Question: Is it possible to extend Changeset class ?

[janmisek]

I am looking into possibility to add custom computed properties on changeset. Is it possible to extend Changeset class?

Thanks in advance.

The addon exports the class which is an ember object that you can extend on.
I wrote this quick twiddle but it should point you in the right direction.

Thanks alot for explanation I found myself yesterday.

I would also suggest to include this info in readme, because export of changeset class is nowhere documented, default export is "ember-non-extensible" constructror function.

Btw: why the original ember class is wrapped to classic js constructor function exported by default - is it to make original class semi-private or the reason is e.g typescript compat.

The example in that Twiddle doesn't actually work. If you use that method, then the changeset's obj, validationMap, etc are all fixed to the default values ({}) and there is no way to change them. It does not appear that the Changeset class is actually extensible.

Is that intentional? Does it need to be that way?

We should ensure this works with 3.0.0....

This is now documented in the README!
