Updating Ember Data relationships and saving them to the server

Ember Data
1

Edit: never mind. Looks like my backend wasnt allowing those headers lol…

I’m wondering if I’m not doing something correctly, or if I have found a bug and was wondering if anyone could take a look. I’ve looked everywhere and this is what I constantly see on updating them:

Lets say I have a report model and a dashboard model:

// Report model
export DS.Model.extend({
   name: DS.attr('name'),
   category: DS.belongsTo('category', {
      async: true
   }),
   dashboards: DS.hasMany('dashboard', {
      async: true
   })
});

// Dashboard model
export DS.Model.extend({
   name: DS.attr('name'),
   reports: DS.hasMany('report', {
      async: true
   })
});

Lets say that the user wants to add a report (28) to a dashboard (1). Example:

var report = this.store.find('report', 28);
var dashboard = this.store.find('dashboard', 1);

dashboard.then(function(dash) {
   dash.get('reports').addObject(report);
   dash.save();
});

Shouldn’t this then send a request to the server to save this relationship? From what I’m getting, this is Chrome’s output for the request:

My first question is, why does it not include anything in the request that I’m trying to add report 28 to dashboard 1? Also, why is it using “OPTIONS” instead of “PUT”?
