how could I do some async thing in node-orm2's each function?

Question

how could I do some async thing in node-orm2's each function?

I have some code like this:

req.models.order.find({})
  .each(function(order){
    req.models.food.find({orderId: order.id}{
      //...
      order.foods = ['...'];
      return order;
    })
  })
  .get(function(order){
    //the orders have no 'foods' attribute
  })

How could I fix it?

javascript
mysql
node.js

First of all, you can use associations (like one-to-many or many-to-many), which would be the most preferable path to go.

The other way to do it (maybe not too pro, but surely works) is to make a counter initialized with number of returned orders, decrementing with every next "each" iteration, and eventually firing "get" inside the "each" when the counter reaches 0.
