Question

When using this user.meta.logins.$inc(); I get this error in the console:

Mongoose MongooseNumber#$inc / MongooseNumber#increment is deprecated.
Use Model.update() to get incrementation in v3 instead.

What I have beed doing is this (code is stripped down to the basic usage):

userSchema.methods = {
  userFind : function (user, pass, callback) {
    this.model('user').findOne({ 'username':user, 'password':pass }, callback); 
  }
}

var userModel = new model();
userModel.userFind(username, password, function(err, user) {
  user.meta.logins.$inc();
  user.meta.last_action = new Date();                   
  user.save();
});

This works just fine but since the deprecation is at hand, I want to use the proposed Model.update() method to update the user, however I can’t make it happen.

I have tried doing userModel.update() and user.update() but in both cases I get errors. Maybe my syntax is wrong for the update.

Any ideas would be much appreciated.

To use update for this:

userModel.update(
  { 'username': user, 'password': pass },
  { $inc: { logins: 1 }, $set: { last_action: new Date() }},
  function(err, numAffected) {
    ...
});
