我有两个这样的模型:
App.Build = DS.Model.extend({
allegiance: DS.attr('string'),
profession: DS.attr('string'),
skills: DS.hasMany('skill')
});
App.Skill = DS.Model.extend({
name:DS.attr('string'),
value:DS.attr('number')
});
在我的应用程序中,我有控件来设定每项技能的忠诚度,专业和价值(最高可达55)。
然后在我的应用程序控制器的动作哈希中,我有一个动作将构建模型保存到服务器。
save:function(){
var store = this.get('store');
var skills = this.get('controllers.skills').get('model');
console.log(skills);
var build = store.createRecord('build',{
profession:1,
allegiance:1,
skills:skills
});
build.set('skills',skills);
build.save();
console.log('Saved!');
}
但是当构建模型发送到服务器时,技能属性是一个空数组:
{"build":{"allegiance":"1","profession":"1","skills":[]}}
我确定我做错了什么,但我无法弄清楚什么,也找不到任何关于它的好文档。另外一点,我关心提交的是技能ID和价值。
任何帮助将不胜感激!
更新:
根据Daniel的建议,我编辑了保存功能,使用pushObjects将技能放入Build模型,然后保存。它现在工作得更好。生成的帖子数据现在就像这样:
{"build":{
"allegiance":1,
"profession":1,
"skills":["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55"]}}
这是技能ID的列表。在帖子中没有提交任何其他属性。我已经尝试迭代技能,创建一个新对象,只是推入id和值,这是我需要的唯一部分,但这给了我一个错误。有点像,不能使用undefined,必须是类型技能。
这似乎是Ember数据应该本地处理的东西。是否有一些我缺少的东西让它在请求中发送其他技能属性?
谢谢!

如果有其他人感兴趣,我通过使用Build
模型的自定义serliazer覆盖serlizer解决了这个问题:
App.BuildSerializer = DS.RESTSerializer.extend({
serializeHasMany: function(record, json, relationship) {
if(relationship.key === 'skills') {
var skills = record.get('skills');
var block = [];
skills.forEach(function(skill, index) {
var current = {};
current.id = skill.get('id');
current.value = skill.get('value')
block[index] = current;
});
json['skills'] = block;
} else {
return this._super(record,json,relationship);
}
}
});
更新:
现在可以使用DS.EmbeddedRecordsMixin这样一种更简单的方法:
App.BuildSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin,{
attrs: {
skills: 'records'
}
});

技能模型是RecordArray吗?这是Ember数据使用的基础模型。您可以尝试创建记录,然后在事后使用pushObjects。
var build = store.createRecord('build',{
profession:1,
allegiance:1
});
build.get('skills').pushObjects(skills);
另外,save会返回一个promise,所以为了正确处理成功保存而不是失败,你可以像这样处理它。
build.save().then(
function(){
console.log('Saved!');
},
function(){
console.log('Failed to save');
});
