Answer 1

Use select property in populate as:

User.populate(user, { path: 'shortList.flat.project', model: 'Project', select: 'name' })

This will give you name of project only.

To give specify fields which you don't want you can zero as:

User.populate(user, { path: 'shortList.flat.project', model: 'Project', select: { 'name': 0, 'Floor': 0, 'flats': 0, 'towers': 0,} }

This works for me.

and if you are doing two level populations:

we can simply do it as:

populate('project.tower', 'name project flats');

for a simple populate to get specific feilds:

populate('project', 'name')
