pass variable across multiple controllers in sails

I have two controllers namely user and calendar. I have to pass user object from the user to calendar. How can we pass variable across multiple controller in sails?

I'm just starting with sails (and node.js generally speaking), but I'm fearly common with javascript (client sided).

The only way I found out was using the variable scope. If you declare a variable before any anonymous function, you'll be able to edit this variable from inside the function. So inside your action in your controller you'll have something like :

        //this will allow me to store my informations inside the categories variable.
        var categories;
        Categories.find().done(function(err, cat){
            categories = cat;
        });

        //calling another datas and passing them to the view, alongside with my previous datas
        Categories.findOne(id).done( function(err, cat){
            return res.view({
                data : cat,
                cats : categories
            });
        })

I'm sure they're a lot of better ways, and I'm interested in knowing them =)

In your CalendarController.js:

module.exports = {

foo: function(req, res, next) {

    User.findOne(2).exec(function(err, user) {

        if (err) return next(err);

        res.json(user);

    });
},


/**
 * Overrides for the settings in `config/controllers.js`
 * (specific to CalendarController)
 */
_config: {}

};

Off the top of my head, I would say that you could use session. Though in terms of design, a situation when you are passing a variable from one controller to another should be really questionable.
