我有两个商店的民意调查和'选择'，其各自的模型为"民意调查"one_answers"选择"
模型
poll
Ext.define('PollsTest.model.Poll', {
extend: 'Ext.data.Model',
xtype : 'poll',
config: {
fields: [
{ name: 'title'},
{ name: 'uri' },
],
hasMany :
[
{
model : 'PollsTest.model.Choices',
name : 'Choices',
primaryKey : 'title',
foreignKey : 'title',
foreignStore : 'Choices'
}
]
}
});
选择
Ext.define('PollsTest.model.Choice', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'choice', type: 'auto' },
{ name: 'votes', type: 'auto' },
{name : 'title', type: 'auto'},
{name : 'uri', type : 'auto'}
],
belongsTo : {
model : 'PollsTest.model.Choices',
name : 'Choices',
primaryKey : 'title',
foreignKey : 'title',
foreignStore : 'Choices',
getterName: 'getChoices',
setterName: 'setChoices'
}
}
});
商店
民意调查
Ext.define('PollsTest.store.Polls',{
extend : 'Ext.data.Store',
alias : 'store.pollStore',
//xtype:'pollStore',
requires :
[
'PollsTest.model.Poll',
'Ext.data.proxy.JsonP',
'Ext.data.reader.Json'
],
config :
{
autoLoad : true,
model : 'PollsTest.model.Poll',
storeId :'pollStore',
listeners :
{
load : function(store, records)
{
console.log('store loaded',records);
}
},
//storeId : 'pollstore',
proxy :
{
type : 'jsonp',
url : 'http://localhost/polls',
reader :
{
type : 'json',
rootProperty : 'polls'
}
}
},
});
选择
Ext.define('PollsTest.store.Choices',{
extend : 'Ext.data.Store',
alias : 'store.choiceStore',
requires :
[
'PollsTest.model.Choice'
],
config :
{
autoLoad : false,
model : 'PollsTest.model.Choice',
storeId :'choiceStore',
listeners :
{
load : function(store, records)
{
console.log('choice store loaded',records);
}
},
proxy :
{
type : 'jsonp',
url : '',
reader :
{
type: 'json',
rootProperty : 'choices'
}
}
},
});
so从 polls 存储中，我可以填充我的列表，然后单击列表项目，控制器将详细信息面板推向视图。选择存储将根据列表上发生的TAP事件填充。因此，问题是我必须将详细信息面板推到View 之后，才加载选择存储
之后我该怎么做？建议。
我的控制器看起来像这样
Ext.define('PollsTest.controller.MainController', {
extend: 'Ext.app.Controller',
requires : ['PollsTest.controller.ChoiceController'],
config: {
refs: {
mainController : 'mainpanel',
controller_list : 'pollslist',
details_controller : 'pollsdetails'
},
control: {
controller_list :
{
itemtap : 'ShowPoll'
},
}
},
ShowPoll : function (list, index, target, record, e, eOpts)
{
var tochoice = record.data.uri;
var main_path = 'http://localhost';
var choices_url = main_path+tochoice;
var choice_store_object = Ext.getStore('choiceStore');
choice_store_object.getProxy().setUrl(choices_url);
choice_store_object.load();
console.log(choice_store_object.getCount());
/* var choices_store_object = Ext.create('PollsTest.store.Choices');
var checking = choices_store_object.on('load',function(){return true;});
if(checking==true) --> didn't work no detail panel pushing is happening but the order of loading the stores works fine here.
{
*/ console.log('before pushing');
this.getMainController().push({xtype : 'pollsdetails',data : record.data });
console.log('after Pushing');
// }
//this.getApplication().getController('ChoiceController').onDetailsShow(this,record,tochoice);
}
});
您可以在选择商店加载功能中传递回调功能。在商店加载后将执行回调函数。
choice_store_object.load(function(records, operation, success) {
// push the pollsdetails view here
}, this);
这就是我实现的方式
var choices_store_object = Ext.create('PollsTest.store.Choices');
var checking =choice_store_object.load(function(records, operation, success)
{
console.log('before pushing');
this.getMainController().push({xtype : 'pollsdetails',data : record.data });
console.log('after Pushing');
}, this);
