问何时在Sails模型中调用beforeUpdate方法？

EN

module.exports = {

    attributes: {

        login: {
            type: 'string',
        },

        password: {
            type: 'string',
        },

        birthDate: {
            type: 'date',
        }
    },

    beforeCreate: function(values, next) {
        //someCode();
    },

    beforeUpdate: function(values, next) {
        console.log("i\'m here!");
        if (values.birthDate && _.isNaN(Date.parse(values.birthDate))) {
            console.log(values.birdDate);
            return next({err: ["Wrong date!"]});    
        }

        values.birthDate = Date.parse(values.birthDate);
        next();
    }
};
