我从模型中获取数据。将模型集成到页面后，当我刷新页面时，数据就会消失。
我想阻止数据仍在刷新。在EmberJs data中执行此操作的正确方法是什么，向我显示阻止export default Ember.Route.extend({
model: function(params) {
return this.store.peekRecord('card-list', params.id ); //works
}
});
刷新的正确方法？
我的型号代码：
import Ember from 'ember';
export default Ember.Route.extend({
model: function(params) {
if(this.store.hasRecordForId('card-list', params.id)){
return Ember.RSVP.hash({
model: this.store.peekRecord('card-list', params.id )
})
}
//I am trying for refresh. but throws error as
//Error while processing route: cs2i.balance.balanceEdit Ember Data Request GET /api/card-lists/4196074912005007 returned a 404
return Ember.RSVP.hash({
model: this.store.findRecord('card-list', params.id )
})
}
});
提前致谢。

您可以检查现有记录，除非提取该记录。
export default Ember.Route.extend({
model: function(params) {
if(this.store.hasRecordForId('card-list', params.id))
return this.store.peekRecord('card-list', params.id );
return this.store.findRecord('card-list', params.id );
}
});

你必须偷看＆＃39;使用查询或findRecord或findAll等获取记录的父路线的记录...所以 - 可能有很多原因导致您的数据消失了......
如果你不在某个孩子的路线上...... peekRecord没有任何东西可以偷看......所以，你必须检查记录......或者从父路线获取modelFor（＆＃39; model-name＆＃39;） - 所以，您需要提供有关代码上下文的更多信息。< / p>
// imports whatevers...
model(parameters) {
return this.store.findRecord('thing', parameter.id);
}
...或
model() {
var x = this.modelFor('parentModel');
// do something with x... query... find etc...
}
