I want to count both the number of agreements and the number of contacts in a document, and group the data on company name and orgId.
This is my desired output:
{
"Company": "Multi-Metal Manufacturing",
"Organization": "1",
"AgreementCount" : 1,
"ContactCount" : 4
}
I tried this solution, but result is not as expected; it gives me a general count of all fields, but I want a specific count:
return Company.aggregate(
{"$unwind":"$agreement"},
{"$unwind":"$contact"},
{"$unwind":"$companySite"},
{ $group: {
_id: {
"Organization": "$orgId",
"Company": "$name"
},
"count": { $sum: 1 } } },
{"$project": {
"_id": 0,
"Company": "$_id.Company",
"Organization":"$_id.Organization",
"Count": "$count"
}
})

Assuming Companyname/orgId is unique, you can use $size which will get the size of your arrays to make this pretty simple:
[
{
$project:{
_id:false,
Company: "$name",
Organization: "$orgId",
AgreementCount: {
$size: {$ifNull: ["$agreement",[]]}
},
ContactCount: {
$size: {$ifNull: ["$contact",[]]}
}
}
}
]
If Companyname/orgId are not unique, then you can introduce a $group stage to sum the counts produced by $size :
[
{
$project:{
_id:false,
Company: "$name",
Organization: "$orgId",
AgreementCount: {
$size: {$ifNull: ["$agreement",[]]}
},
ContactCount: {
$size: {$ifNull: ["$contact",[]]}
}
}
},
{
$group: {
_id:{
Company: "$Company",
Organization: "$Organization"
},
AgreementCount: {$sum:"$AgreementCount"},
ContactCount: {$sum:"$ContactCount"}
}
},
{
$project:{
_id: false,
Company: "$_id.Company",
Organization: "$_id.Organization",
AgreementCount: true,
ContactCount: true
}
}
]
