uni-data-picker 无法渲染数据库获取到的数据。

模拟了下数据是可以实现的，你这个data-entry 是个组件吗

<template>  
    <view class="container">  
        <uni-section title="数据" type="line">  
            <view class="uni-px-5 uni-pb-5">  
                <uni-data-picker placeholder="请选择班级" popup-title="请选择" :localdata="classDataTree" v-model="classValue"></uni-data-picker>  
            </view>  
        </uni-section>  
    </view>  
</template>  

<script>  
    import {onMounted} from 'vue'  
    export default {  
        data() {  
            return {  
                classValue: '1-2',  
                classDataTree: [],  
                classDataTree2: [{  
                        text: '一年级',  
                        value: '1-0',  
                        children: [{  
                                text: '1.1班',  
                                value: '1-1'  
                            },  
                            {  
                                text: '1.2班',  
                                value: '1-2'  
                            }  
                        ]  
                    },  
                    {  
                        text: '二年级',  
                        value: '2-0',  
                        children: [{  
                                text: '2.1班',  
                                value: '2-1'  
                            },  
                            {  
                                text: '2.2班',

                        ]  
                    },  
                    {  
                        text: '三年级',  
                        value: '3-0',  
                        disable: true  
                    }  
                ]  
            };  
        },  
        mounted() {  
            this.classDataTree.push(...this.classDataTree2)  
        },  
        methods: {  

        }  
    };

</style>

用的是uni-starter的模板，搞了我几天，也没有人能回答。。。。。。
一直以为我自己不对，原来更新一下就行了，这坑啊。

解决办法连接

我在uni-app x+vue3中完全复制你的代码报错 [Vue warn]: Invalid prop: type check failed for prop "gettree". Expected Object, got String with value "". \n at <UniDataPicker>\nat <View>\nat <Home>\nat <AsyncComponentWrapper>\nat <PageBody>\nat <Page>\nat <Anonymous>\nat <KeepAlive>\nat <RouterView>\nat <Layout>\nat <App>

只能显示一级菜单
