Store serverside javascript functions in MongoDB using Mongoose

Question

I've been trying to store server side functions in MongoDB (from the client side)

I'm trying this, from the examples:

db.system.js.save({_id: "sum",
              value: function (x, y) { return x + y; }});

But that does not work. I am using Mongoose, so I don't know if it has a wrapper around the plain Mongo DB object.

It should...What is the exact error message you get from trying to run that command above? — Sammaye

That db.system is undefined. Mind you: this is on the client side, inside a node.js program. So not in a mongo shell. I can use db.eval. — Jelle De Loecker

It should allow you connect to the system.js collection through node much the same way, I am no genuis when it comes to node.js — Sammaye

Use the mongoose-function plugin to add function support to mongoose.

Then create a schema and force its collection name:

new Schema({ value: Function }, { collection: 'system.js' })
