Question

我正在努力实现这一目标部门-HasMany-＆gt;联系人。

没有任何线索部门得到保存但联系人没有得到保存

您可以在jsbin

中参考此部分

App.NewcontactController = Ember.ObjectController.extend({
 needs: ['department'],
 save: function () {
     var department = this.get('controllers.department').get('model');
      var newContact = App.Contact.create({
         name: this.get('name'),
         department: department
     });
     department.get('contacts').addObject(newContact);
     console.log(department);
     console.log(newContact);
     department.get('contacts').save();

     department.save();
     console.log('---saved contact---');
     this.transitionTo('contact',newContact);
 }

}）;

Firebug LocalStorage

Contact-1        "{"id":"1","department_id":"1"}" 
Department-1     "{"id":"1","name":"A","contact_ids":[]}" //NO ids :(

保存父级不会保存子级。您有责任自己拯救孩子。在hasMany关系上有一个save方法可以让它更容易一些。

Ember-Model hasMany不保存模型emberjs
