Hi!

I'm for sure doing something wrong, but maybe somebody can clarify it. Thanks in advance!
So let we say i have two simple models user -> { id:attr(), role:DS.belongsTo('role''), desc:attr() } and role -> { id:attr(), label:attr() }
Everything works fine for display. Instead of role id I can show it's related label.
But when it comes to update or save - it's real pain (at least for me :slight_smile: )
I can`t use (mut (get ... )) anymore? Every time I need handle this via actions and do something like user.set('role', store.peekRecord('role', id));
When in case of primitive attributes (mut (get ...)) works fine.

So. Instead of using belongsTo I can use computed props and it will look like
user -> { id:attr(), role:attr(), roleLabel:computed('role',function() { return this.store.findRecord('role',this.get('role')); }, desc:attr() }
I still able to display role label, and i can use (mut (get ... )) because it's computed prop now.
Less pain to save data in db ( it`s pretty much simple db row user, role, desc where role just a number).

The same story with hasMany.

So what is real purpose of using belongsTo? What i'm doing wrong?
Please help! :slight_smile:
