Mongoose use of .select() method

Question

I\'m pretty confused with the use of the select method. This is how I use it, and it\'s wrong:

Transaction.find({username : user.username}).sele         


        

Answer 1

Select method is used to select which fields are to be returned in the query result, excluding select means we want all the fields to be returned, here is simple usage as per the docs.

// include a and b, exclude other fields  
query.select('a b');

// exclude c and d, include other fields  
query.select('-c -d');
