我正在使用 Ember 和 Ember-Data 的最新代码。我有rails作为我的后端提供JSON,它工作正常。我希望能够使用视图中的复选框过滤 Ember 模型的“活动”属性。如果我选中复选框,我希望复选框仅显示 active=true 的数据。我不想从数组中删除数据,只隐藏数据。这是我目前拥有的,但它不起作用。
模型:
App.Org = DS.Model.extend({
code: DS.attr('string', { defaultValue: 'N/A' }),
name: DS.attr('string', { defaultValue: 'N/A' }),
source: DS.attr('string', { defaultValue: 'N/A' }),
status: DS.attr('string', { defaultValue: 'N/A' }),
type: DS.attr('string', { defaultValue: 'N/A' }),
note: DS.attr('string', { defaultValue: 'N/A' }),
financial_Flag: DS.attr('string', { defaultValue: 'N/A' }),
expense_Flag: DS.attr('string', { defaultValue: 'N/A' }),
revenue_Flag: DS.attr('string', { defaultValue: 'N/A' }),
created_At: DS.attr('string', { defaultValue: 'N/A' }),
updated_At: DS.attr('string', { defaultValue: 'N/A' }),
active: function() {
var status = this.get('status');
var active = (status === 0) ? false : true;
console.log("status: " + status + " | active: " + active);
return active;
}.property('status')
}).reopenClass({
collectionUrl: '/orgs',
resourceUrl: '/orgs/%@',
resourceName: 'org'
});
阵列控制器:
App.OrgsController = Em.ArrayController.extend({
isEmpty: function() {
console.log("############ App.OrgsController.isEmpty called");
return this.get('length') === 0;
}.property('length'),
toggleActive: function(){
console.log("############ App.OrgsController.isActive called");
return this.filterProperty('active', value).forEach(this.removeObject, this);
}.property('@each.active'),
init: function() {
this.set('content', App.store.findAll(App.Org));
},
refreshOrgs: function() {
this.set('content', App.store.findAll(App.Org));
},
getInactiveOrgs: function(){
this.set('content', App.store.find(App.Org, {status: "0"}));
}
});
在我看来,我有:
<label>
isActive
{{view Ember.Checkbox checkedBinding="App.OrgsController.toggleActive" disabledBinding="App.OrgsController.isEmpty" }}
</label>
