load function doesn't return value...

[ijsong]

File: ORM.js
Function: ORM.prototype.load
Issue:
Function load does not return any value when it is success. It is OK when model is loaded with instance of connect function. However, it has some problem using with express function.
In below code, novalue has undefined, because the load function doesn't return. It results in work-around code such as models.user = db.models.user;.

However, it'd be better that models.user = db.load ....

exports.db = orm.express(options, {
  define: function (db, models) {
    var novalue = db.load('./models/user', function (err) {
      if (err) {
        console.log('Fail to load model');
        throw err;
      }
      return db.models.user; /* HAVE NO EFFECT */
    });
    models.user = db.models.user;
  }
});

That's how async works.

The load is blocking call. So the caller is stopped until require(file)(this, cb) is done.

[vendethiel]

That's true, my bad. I blindly assumed that since it uses a callback.

Still, it's async. After the require, it will call the module and expect a callback to be invoked, which you could for example use to load things from the network, database, ...

You can of course use it sync, I'm going to change it to return the returned value from the function so you can use it if you want, but that's entirely up to you to create that logic.
