Question

我有两个控制器和两个型号。（我有第三个，groups，但这种情况无关紧要。）我的模型是这样的：

App.Favorite = DS.Model.extend({
    lodge: DS.belongsTo('lodge'),
    notes: DS.attr('string'),
    groups: DS.hasMany('group', {async:true}),
    photo: DS.attr('string'),
});
App.Lodge = DS.Model.extend({
    name: DS.attr('string'),
    address: DS.attr('string'),
    website: DS.attr('string'),
    phone: DS.attr('string'),
    uniqueDescription: DS.attr('string'),
    basicDescription: DS.attr('string'),
    yearOpened: DS.attr('string'),
    propertySize: DS.attr('string'),
    propertyType: DS.attr('string'),
    languages: DS.attr('string'),
    owner: DS.attr('string'),
    uniqueQualifier1: DS.attr('string'),
    uniqueQualifier2: DS.attr('string'),
    uniqueQualifier3: DS.attr('string'),
    uniqueQualifier4: DS.attr('string'),
    lowDayPrice: DS.attr('string'),
    highDayPrice: DS.attr('string'),
    favoriteBoolean: DS.attr('boolean')
});

从我的lodge模板中，我试图“分配”该特定的小屋成为最爱。那么如何从favorite控制器向其模型添加新的lodge记录？据我所知，Ember指南和API似乎没有这个用例。

示例小屋控制器：

App.LodgeController = Ember.ObjectController.extend({
    actions: {
        createFavorite: function() {
            // Not sure what to do here
            //
            // Create new record
            //
            // Then transition to newly created record route
        }   
    }
});

路线：

App.Router.map(function() {
  this.resource('groups', { path: '/groups' });
  this.resource('group', {path: '/group/:group_id'});
  this.resource('favorites', {path: '/favorites'});
  this.resource('lodges', {path: '/'});
  this.resource('favorite', {path:'/favorite/:favorite_id'})
});

我认为您应该可以在createFavorite函数中执行以下操作：

var lodge = this.get('content');
var fav = this.store.createRecord('farvorite',{ lodge : lodge });
var _this = this;  // Inside didCreate 'this' will point to something different
fav.on('didCreate',function(){
  _this.transitionToRoute('favorite',fav);
});
fav.save();

从不同的控制器Ember.js向模型添加新记录
