问题描述
我有两个以上的表，并且已加入$ lookup，并且未使用其他表的引用
var gettopjobs = await jobs.aggregate([
{
$lookup:
{
"from":"tbldevprofiles","localField": "userid","foreignField": "userid","as":"devporfile"
}
},{$unwind: '$devporfile'},{
$lookup:
{
"from":"tblskils","localField": "skills","foreignField": "skillid","as":"jobskills"
}
},{
$lookup:
{
"from":"tbljobcomments","localField": "_id","foreignField": "jobid","as":"jobcmt"
},},{
$lookup:
{
"from":"tblusers","localField": "jobcmt.userid","foreignField": "_id","as":"jobcmtusers"
},{
$addFields: {
skills: {
$reduce: {
input: "$jobskills",initialValue: [],in: {
$concatArrays: [["$$this.name"],"$$value"]
}
}
}
}
},{
$project:{
skills:1,salary:1,jobtype:1,createdon:1,jobtitle:1,category:1,description:1,'devporfile.profileimg':1,'devporfile.location':1,jobcmt:1,jobcmtusers:1,}}
]);
我得到了这样的输出

我要根据用户ID
在 jobcmt 中找到 jobcmtusers 详细信息那么我们如何在单个查询中做到这一点
