What's the best way to attach behavior to a Meteor Collection?

Question

In Meteor, when you retrieve a record from a database, it\'s only a record. So if I have a collection called Dogs, a dog might have fur: \'br

Answer 1

You can use the transform parameter in the Collection to overload the object with custom functions

var Dogs = new Meteor.Collection("dogs", 
{
    transform:function(entry)
    {
        entry.bark = function(){ console.log(this.barkSound);};
        return entry;
    }
});

Then:

var aDogID = new Dogs.insert({barkSound: "ruff"})
Dogs.find(aDogID).bark(); // "ruff"

Bonus: If for any reason you would like to use a similar concept as proposed by Andrew Ferk, just use the _.defaults(object, *defaults) function.

var defaults = {
             barkSound: "ruff",
             bark: function() {
                        console.log(this.barkSound);
                    }
            }

Dogs = new Meteor.Collection("dogs",
        {
            transform: function(object) {
                return _.defaults(object, defaults);
            }
        });
