从生成的进程访问Sails控制器

Question

I'm trying to spawn a background service upon Sails' lift. Here's what I've come up with so far :

config/bootstrap.js :

module.exports.bootstrap = function(cb) {

    sails.on('lifted', function() {
        var spawn = require('child_process').spawn;
        var worker = spawn('node', ['./worker.js']);
    });

    cb();

};

worker.js :

var sails = require('sails');

sails.controllers.MyController.myFunction(null, function(data) {
    console.log(data);
});

When I lift Sails, I get the following error : Cannot read property 'MyController' of undefined .

I tried without the require('sails') and without the sails.controllers in front of my controller's name, but then it throws me MyController is not defined .

Any idea why I can't access my controller from the bootstrap function ?

You need to load or lift the Sails app in order to be able to access controllers, models, etc. See sails.load() and sails.lift() for more details. So it'd be something like:

var sails = require('sails');
sails.load(function(err, sails) {
   if (err) {
     // handle error and exit process
   }
   // sails is now fully loaded
   sails.controllers.my.myFunction(null, function(data) {
      console.log(data);
   }
});

Side note, it's also weird to run controller code outside of the context of a request. You probably should refactor that code into a service instead. And as @elssar notes above, controller identities are lowercased and the "controller" part is removed.
