1. //模拟数据库数据
2. {
3. "_id":"1234",
4. "name":"name1",
5. "weights":[
6. {"detailid":"11111","rWeight":"25","shuzhu":[]},
7. {"detailid":"22222","rWeight":"26","shuzhu":[]}
8. ]
9. }
10. ///下面是云函数
11. db.collection('collectionName') .where({ 'weights.detailid': '11111' }).update({
12. data: { 'weights.0.shuzhu':_.push({
13. each:[{data1:'3'},{data2:'4'}] }) } })

最近学习做个小的作业，这个'weights.0.shuzhu' 那个0有什么办法可以写成活的

请求个大佬告知！
