我在后端使用ember-data和activemodel适配器和rails和mongoid(mongodb)。每当我向rails应用程序发出请求时,emberjs都会显示返回的数据,但在Chrome开发者控制台中显示:
Assertion failed: You must include an `id` in a hash passed to `push`
在jsfiddle中重现的问题
我已在此 jsfiddle 中重现了此问题。当我使用 id 而不是 _id 时,您可以看到同一个 jsfiddle 的不同版本。
后端发送的有效负载
ActiveModel适配器将snake_case start_date 转换为驼峰大小写。我在ember-data rest-serializer中添加了一些自定义代码,将 _id 转换为 id ,并且在此问题中将代码粘贴到较低的位置。
{"schedules":[
{
"_id":"529f38596170700787000000",
"name":"Hair styling",
"start_date":"2013-12-12"
}
]}
现在,虽然返回的有效负载包含 id ,但如果我进入google cgrome控制台并运行下面的命令并访问 _data ,它显示 id 未定义。
a = App.__container__.lookup("controller:schedules")
b = a.get('content')
我使用控制台中的披露箭头并深入了解 _dat 对象,这就是我所看到的
_data: Object
id: undefined
自定义序列化代码
我扩展了activemodeladapter,将mongodb的_id转换为id并将其设置为主键。
App.ApplicationSerializer = DS.ActiveModelSerializer.extend({
primaryKey: '_id',
normalize: function(type, hash, prop) {
this.normalizeMongoidId(hash);
return this._super(type, hash, prop);
},
normalizeMongoidId: function(hash){
var json = { id: hash._id };
delete hash._id;
//hash.id = hash._id;
//delete hash._id;
}
/*
serialize: function(record, options){
var json = this._super(record, options);
json.schedule._id = json.record.id;
delete json.record.id
return json;
}
*/
});
余烬数据模型:
App.Schedule = DS.Model.extend({
name: DS.attr('string'),
organization: DS.belongsTo('organization')
});
这是我的emberjs路由器
App.Router.map(function(){
this.resource('schedules', {path: "/schedules"}, function(){
this.resource('schedule', {path: "/:schedule_id"}, function(){});
});
});
emberjs路线定义:
App.SchedulesRoute = Ember.Route.extend({
model: function(){
return this.store.find('schedule');
}
});

答案 0 :(得分:0)
我有同样的问题。在你的rails序列化程序中进行计划,(假设你有一个),你应该做
attributes :id, :name, :start_date
并有一个
has_many :schedule
在SchedulesSerializer中。如果有效,请告诉我。
