如何获取绑定和过滤 viewModel.hasMany 关系同步的商店？

我在 extjs5 中有两个网格面板。说第一个网格是组和第二个用户。我将组网格绑定到 viewModel stores.groups。该组存储正在工作并且还通过模型代理同步（模型绑定在 viewModel 中）。第二个网格通过 绑定到同一个 viewModel bind:{groupsReference.selection.users}。绑定有效。在选择组时，过滤用户。更改某些用户数据会将用户记录标记为脏。

问题：脏用户不再自动同步，我也无法弄清楚如何手动同步它。我怎样才能让 autoSynced 在这里工作？如何触发手动同步？

除了 hasMany/belongsTo 关系之外，用户组的模型是相同的：

Ext.define('MyApp.model.Groups', {
    extend: 'Ext.data.Model',

    fields: [
        { name: 'id', type: 'int' },
        { name: 'groupname', type: 'auto' }
    ],
    autoLoad: true,
    autoSync: true,
    proxy: {
        type: 'rest',
        url: '/api/groups',
        reader: {
            type: 'json',
            rootProperty: 'data',
            successProperty: 'success'
        },
        writer: {
            type: 'json'
        }
    },
    hasMany: {
        model: 'MyApp.model.Users',
        store:'MyApp.model.Users',
        name: 'users',
        foreignKey:'testId',
    }
});

和视图模型

Ext.define('MyApp.view.main.MainModel', {
    extend: 'Ext.app.ViewModel',
    requires: ['MyApp.model.Groups','MyApp.model.Users'],
    alias: 'viewmodel.main',
    stores: {
        groups: {
            model: 'mfct.model.Experiment',
            autoLoad:true,
            autoSync:true
        },
        users: {
            model: 'mfct.model.Variation',
            autoLoad:true,
            autoSync:true
        }
    }

});

这是我的代码，它可能不是最好的方法，但至少它是有效的。希望这可以帮助你一点。

面料订单模型

Ext.define('MyApp.model.FabricOrder', {
    extend: 'Ext.data.Model',

    requires: [
        'MyApp.model.SizeInfo'
    ],

    fields: [
        {name: '_id', type: 'string'},
        {name: 'styleno', type: 'string'},
        {name: 'modelname', type: 'string'},
        {name: 'colour', type: 'string'},
        {name: 'contractno', type: 'string'},
        {name: 'total', type: 'int'},
        {name: 'deliverydate', type: 'date', dateFormat: 'Y-m-d'},
        {name: 'comment', type: 'string'}
    ],

    hasMany: [{
        model: 'MyApp.model.SizeInfo',
        name: 'sizes'
        // This is not working in Extjs 5.0.0
        //storeConfig: {
        //   autoSync: true,
        //   proxy: {//etc.}
        //}
    }],

    idProperty: '_id'
});

尺寸信息模型

Ext.define('MyApp.model.SizeInfo', {

    fields: [

视图控制器

Ext.define('MyApp.view.fabric.FabricController', {
    extend: 'Ext.app.ViewController',

    alias: 'controller.fabric',

    id: 'fabricController',

    init: function() {
         this.control({
            'grid[name=fabricgrid]': {

            },
            'grid[name=sizegrid]': {
                reconfigure: 'onSizeGridReconfigure'
            }
         });
     },

    onSizeGridReconfigure: function(gird, store, columns, oldStore, oldColumns, eOpts) {
        if(store) {
            // Override the default association store settings
            store.autoSync = true;
            store.proxy = this.getViewModel().getStore('sizeInfos').getProxy();
            store.onCreateRecords = this.getViewModel().getStore('sizeInfos').onDestroyRecords
            store.onUpdateRecords = this.getViewModel().getStore('sizeInfos').onUpdateRecords;
            store.onDestroyRecords = this.getViewModel().getStore('sizeInfos').onDestroyRecords
        }
    }
});
