我有一个类似
的集合{
"Aid":12234,
"items":{
"itemId":"SP897474",
"Blocks":[
{
"blockId":"W23456",
"name":"B1",
"innerBlock":[
{
"id":"S23490",
"name":"IB1",
"state":true
},
{
"id":"S23491",
"name":"IB2",
"state":true
},
{
"id":"S23492",
"name":"IB3",
"state":true
}
],
"active":true
},
{
"blockId":"W23457",
"name":"B2",
"innerBlock":[
{
"id":"S23482",
"name":"IB1",
"state":true
},
{
"id":"S23483",
"name":"IB2",
"state":true
}
],
"active":false
}
]
},
"active":true
}
由于嵌套，我无法更新innerBlock数组的字段，特别是名称，状态。基本上，我想更新提到的字段。我已经尝试过这个查询
User.update({
"items.Blocks.innerBlock.id": req.body.id,
"Aid": req.body.Aid
}, {
"$set": {
"items.Blocks.$.InnerBlock.$.name": req.body.name
}
})
显示下面给出的错误
"errmsg": "Too many positional (i.e. '$') elements found in path 'items.Blocks.$.InnerBlock.$.name'"
我不知道如何修复它。在mongo shell中可以查询什么？感谢。
