Remove multiple documents from mongo in a single query

Question

I have a list of mongo \'_id\' which I want to delete. Currently I am doing this

# inactive_users -->  list of inactive users 
for item in inactive_users:         


        

Answer 1

var collection = db.users;
var usersDelete = [];
var ObjectID = req.mongo.ObjectID;   //req is request from express

req.body.forEach(function(item){     //req.body => [{'_id' : ".." , "name" : "john"}]
    usersDelete.push(new ObjectID(item._id));
});

collection.remove({'_id':{'$in': usersDelete}},function(){
    //res.json(contatos);
});
