问题描述

我正在尝试实现这个
部门-HasMany->联系人。

I am trying to achieve this Department -HasMany->Contacts.

没有线索部门得到保存，但联系人没有得到保存

Have no clue Department gets saved but Contacts doesnt get Saved

您可以在jsbin中引用此部分

you can refer this section in jsbin

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);
 }

}）;

推荐答案

p>保存父级别不会保存子级。你有责任自己拯救孩子。 hasMany关系中有一个 save 方法，使其更容易一些。

Saving a parent doesn't save children. You are responsible for saving the children yourself. There is a save method on the hasMany relationship to make this a little easier.
