Counting number of documents for each subcollection
I have a MongoDB database in which there are 2 collections namely Projects and Sub-Projects. Sub-Projects have a lookup field to the Projects collection.
Projects
{_id: 123, parent_id: 123}
{_id: 124, parent_id: 123}
{_id: 125, parent_id: 124}
Sub-Projects
{project_id: 123, sub_project_id: 543}
{project_id: 123, sub_project_id: 544}
{project_id: 124, sub_project_id: 545}
{project_id: 124, sub_project_id: 546}
Now I want to get a list of Project IDs where a sub-project has been assigned a sub_project_id from other projects.
Currently I'm doing something like this:
db.projects.aggregate([
{ $match: { parent_id: "123"}},
{ $group: {_id: null, projects: { $ be359ba680
