Ember-Data的部分更新？

Question

Imagine a bug tracker.

Each ticket contains a lot of data. Now the status of a few tickets from a long list of tickets is updated.

App.Ticket = DS.Model.extend({
    id: DS.attr('number'),
    status: DS.attr('string'),
    ...
});

Currently when invoking save in ember-data this would send the complete models to the server.

What can I do to only send a partial update, like [{"id": 1, "status": "closed"}, {...}] ?

PS: I understand that this is not possible right now, so I'm wondering if there is a workaround / modification that would enable this? (a general-purpose solution is not required).

Answer 1

My current workaround is to specify a readOnly option that excludes the attributes that I don't want to be sent in the POST.

Answer 2

I was looking into this as well and if you want this to apply to all saves, then today you would fix it with a serializer like serializers/ticket.js :

import DS from 'ember-data';

export default DS.RESTSerializer.extend({
  attrs: {
    status: {serialize: false}
  }
});

This would strip out status .
