Can I specify a lifecycle callback that fires for all waterline models in sails.js

问题

I'm trying to add some auditing capability to my sails.js app. The afterUpdate lifecycle callback will give me the proper place to do what I need, but I'm hoping to avoid modifying every model to reference my new code.

Is there a way to specify an afterUpdate callback that will fire on all models?

回答1:

Put your required overrides into config/models.js

module.exports.models = {

  attributes: {},

  afterUpdate: function (valuesToUpdate, cb) {
    // add your logic here...
    console.log('yep, updated');
    cb();
  },
}

The idea is that then all your models obtain this implementation of the method by default. You can also add shared attributes, as given above (currently empty object).
