问题
This is actually a continuation of my previous question and I'm reasking as I've realised I didn't quite ask the question problem and now I have a different error response.
This is in db.js, a separate file while I have the handlers.
Context: I return func like this so that in my index.js, I can continue to perform mongodb sort operation to find users with the smallest timestamp!
In my server console, I get this response.TypeError: db.findWConditionandler is not a function I'm not sure what I'm doing wrong here. Pls advice! Thanks in advance!
回答1:
The problem is because .sort expects a cursor and .findOne() doesn't not give a cursor. Instead, one should use .find()
