2016最后一貼，終于調通一個測試示例，并發現一個BUG？？？－互聯網

真的難點在于第一次調通。糾結五天，終于搞出界面。

也發現了一個書上代碼，編輯用戶時死活不通的情況，我將Links去了，改在data里，我X，，全OK了。。

原來的代碼：

onAdd: function(button, e, options){
        this.createDialog(null);
    },

    onEdit: function(button, e, options){

        var me = this,
            records = me.getRecordsSelected();

        if(records[0]){
            me.createDialog(records[0]);
        }
    },

    createDialog: function(record){

        var me = this,
            view = me.getView();

        console.log(record);

        me.dialog = view.add({
            xtype: 'user-form',
            viewModel: {
                data: {
                    title: record ? 'Edit: ' + record.get('name') : 'Add User'
                },
                links: {
                    currentUser: record || Ext.create('Packt.model.security.User')
                }
            }
        });

        me.dialog.show();
    },

    getRecordsSelected: function(){
        var grid = this.lookupReference('usersGrid');
        return grid.getSelection();
    },

更改后的代碼：

onAdd: function(button, e, options){
        this.createDialog(null);
    },
    createDialog: function(record){
        var me = this,
            view = me.getView(); //#1

        me.dialog = view.add({
            xtype: 'user-form', //#2
            viewModel: { //#3
                data: {
                    title: record ? 'Edit: ' + record.get('name') : 'Add User',
                    currentUser: record || { //#6
                        type: 'User', //#7
                        create: true
                    }//#4
                }
            }
        });

        me.dialog.show(); //#7
    },
    onEdit: function(button, e, options){
        var me = this,
            records = me.getRecordsSelected(); //#1
        if(records[0]){ //#2
            me.createDialog(records[0]); //#3
        }
    },
    getRecordsSelected: function(){
        var grid = this.lookupReference('usersGrid'); //#4
        return grid.getSelection(); //#5
    },
