Hi iam trying to join 2 collections based on parameters I need to pass Property ID as parameter and get that perticular property details from property collection but iam getting whole data from 2 collections.So how can i pass parameter in the aggregate joins in Node js

my code is some thing like this

 

exports.sample = function(req, res){
    var input = req.body;
    var newValues = {UserID:input.UserID,IsFavorite:input.IsFavorite,PropertyId:input.PropertyId}
    console.log(input);
    MongoClient.connect(url, function(err, db){
        if (err) throw err;
          var dbo = db.db("abc");
          dbo.collection('CLC_Isfavorite').aggregate([
              {
                  $lookup:
                  {
                      from: 'CLC_Property',
                      localField:'PropertyId',
                      foreignField:'PropertyId',
                      as:'propertyfavorites'
                    }
                }
                ]).toArray(function(err,result){
                    if (err) throw err;
                    console.log(JSON.stringify(result))
                    res.json({status : 'success', message : 'Records found', result : result});
                    db.close();
                })
    });
}
