SailsJS: beforeUpdate (Lifecycle callback), access current values

Question

It's clear how to access the new values, the first argument contains them

beforeUpdate: function (values, cb) {....}

But how can I access the current values, that are to be replaced?

Answer 1

In order do access current values you will have to make the call and get the current record.

models/user.js
beforeCreate: function (values, cb) {
    User.findOne(this.update.arguments[0].id || this.update.arguments[0]).exec(err, function(originalUser){/*...*/})
}
