项目为空
我想通过seats
在id
中搜索特定对象。
这个特定的座位应该更新。就我而言,我想更新employee
字段。
如果我执行findOne({"seats._id": req.params.id})
,我将退回项目,但是findOneAndUpdate
返回null
。
答案 0 :(得分:2)
您需要$ positional operator,因为seats
是一个数组,如果只想更新一个字段,则应该使用$set运算符
const project = await Project.findOneAndUpdate({
"seats._id": req.params.id
}, {
$set: { "seats.$.employee": req.body.employee }
}
