How to select specific field in nested populate in mogoose
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')
try to do this:
applicantListToExport: function (query, callback) { this .find(query).select({'advtId': 0}) .populate({ path: 'influId', model: 'influencer', select: { '_id': 1,'user':1}, populate: { path: 'userid', model: 'User' } }) .populate('campaignId',{'campaignTitle':1}) .exec(callback); }
