Why is the date cached when saving a record in MongoDB?

Question

MongoDB

When registering a user, in the mongoose schema I increase the date by 7 days.
Here is an example:

{
    reset: { type: Date, default: increaseDate(7);}
}
function increaseDate(n) {
    return new Date(new Date().setDate(new Date().getDate()+n));
}

In general, I take today's date and plus 7 days, but the problem is that the node seems to cache the date during the last restart of the script. The script was restarted 8 days ago, the user logged in today and the reset field contains yesterday's date.
How to be? What to do?

Answer 1

schema.pre('save', function(next) {
// do stuff
next();
});
