我有一个显示宗地列表的路线,以及一个允许用户选择要显示哪个州的宗地的Ember.Select。
App.Parcel = DS.Model.extend({
addresses: DS.attr('array')
});
App.ParcelsRoute = Ember.Route.extend({
state: null,
renderTemplate: function () {
this.render({ outlet: 'parcels' });
},
model: function (params) {
state = params.state;
App.ParcelAdapter.state = state;
App.ImageAdapter.state = state;
return Ember.RSVP.hash({
props: this.store.findAll('parcel'),
states: this.store.findAll('state'),
});
},
setupController: function (controller, model) {
controller.set('states', model.states);
controller.set('props', model.props);
controller.set('selectedState', state);
}
});
App.ParcelsController = Ember.ObjectController.extend({
selectedState: null,
props: null,
states: null,
first: true,
modelReloadNeeded: function () {
if (this.get('selectedState') != undefined && !this.get('first')) {
this.transitionToRoute('/parcels/' + this.get('selectedState'));
}else{
this.set('first', false);
}
}.observes('selectedState')
});
<script type="text/x-handlebars" id="parcels">
{{view Ember.Select content=states optionValuePath="content.id" optionLabelPath="content.id" value=selectedState}}
<input class="search" placeholder="Search"/>
<ul class="list nav">
{{#each props}}
<li>{{#link-to 'parcel' this}}<h3 class="name">{{addresses.0.street_address}}</h3>{{/link-to}}</li>
{{/each}}
</ul>
</script>
当选择转换到新路由时,旧路由数据和新路由都在模型中,但是如果我重新加载页面,则仅加载当前路由数据。有没有办法在没有location.reload()调用的情况下清除控制器中道具的DS.RecordArray?
