Nodejs json object one attribute value does not print while other does

Question

I have a reservation model in my database. This is how I fetch one entry (Using mongoose),

reservationModel.get_reservation_by_user_id(payload.user.id, function (err, reservations) {
      if (err) {
        console.log(err);
      } else {
        console.log(reservations);
        console.log(reservations[0].user);  // prints undefined                         
        console.log(reservations[0].from); // prints 0900
      }
    });

Here is the console output.

How can I get the value of user?

Can you edit your question to include the schema definition for `reservationModel`? Most probably you haven't added the field in the schema definition. — chridam, Feb 17 '18 at 21:00
Thank you so much, I had written user_id instead of user in my schema. — M.Shaikh, Feb 17 '18 at 21:02

If you want to get a record by id you need to use a method findById. Example:

reservationModel.findById(payload.user.id, function (err, reservations) {
      if (err) {
        console.log(err);
      } else {
        console.log(reservations);
        console.log(reservations.user);                     
        console.log(reservations.from);
      }
    });

I have written a logic to find reservation in my own function `get_reservation_by_user_id` and when I log the response it shows fine as I displayed that in the output as well. So I dont think the problem is with the method call. – M.Shaikh Feb 17 '18 at 21:00
I understood you. Sorry for wrong answer. – Aleksei Korkoza Feb 17 '18 at 21:02

I had 'user_id' written in my schema and not 'user', this was the error.
