在extjs4中获取加载的存储 [英] Getting a loaded store in extjs4

问题描述

当我尝试从控制器获取一个加载的存储时，我变为null。负载也是成功的。我已经验证了。

I am getting null while I try to obtain a loaded store from the controller. The load is a successful one too. I verified that.

我有这个商店如下。

Ext.define('GridApp.store.schemedatastore',{
    extend: 'Ext.data.Store',
    model: 'GridApp.model.schemedatamodel',
    autoLoad: true,
    alias: 'store.schemedata',
    storeId: 'schemedatastoreid',
    constructor:function(){
        console.log('Calling parent');
        this.callParent(arguments);
        },
    listeners: {
        load:function(store,records,isSuccessful){
            if(isSuccessful){
                console.log('Load successful');
            }
            console.log(records[0].get('name'));
            console.log('scheme Data store loaded too.');
        },
    }
});

在我的控制器中，我添加了，

In my controller I added like,

stores: ['schemesstore',
             'schemedatastore'],

我尝试在控制器中以这两种方式访问​​，

I tried accessing in these both ways in the controller,

Ext.getStore（'schemedatastoreid'）; 它返回null和
this.getschemedatastoreStore（）; 这说明它是控件中的一个未定义的函数。

Ext.getStore('schemedatastoreid'); which returns null and this.getschemedatastoreStore(); which says it is an undefined function in controller.

我在这里遗漏了一些东西吗？

Am I missing something over here?

推荐答案

尝试以下任何一种：

this.getSchemedatastoreStore()

// the non-alias version of getStore    
Ext.StoreManager.lookup('schemedatastoreid') 

// in case MVC behavior overrides your storeId config
Ext.StoreManager.lookup('schemedatastore') 

如果您没有定义自己的名称，MVC模式将自动将商店类名称自动存储为商店ID。

MVC pattern will give your store the store class name as a store ID automatically if you don't define your own.

所以如果你删除你的 storeId：'schemedatastoreid' config然后你会自动获得一个storeId为 schemedatastore 。我通常不会给MVC存储一个单独的 storeId config，所以我不知道它是否在某处造成冲突。我通常也不会给我的商店一个别名，这可能会导致 getStore 功能一些困难。

So if you delete your storeId: 'schemedatastoreid' config then you will automatically get a storeId of schemedatastore. I don't normally give MVC stores a seperate storeId config so I don't know if it causes a conflict somewhere. I also don't normally give my stores an alias either, that might be causing the getStore function some difficulties too.
