model-transform

Common toJSON Transform for KeystoneJS / Mongoose Models.

Automatically renames _id to id, removes __v and can optionally run an additional transform.

The transform method may return a new object, or modify the provided one by reference.

Changes from 1.x -> 2.x

In 1.x, the document object was the first argument of the transform function.

In 2.0.0 and up, the document object is this and rtn is the first argument.

Usage

npm install model-transform --save
var keystone = require('keystone');
var transform = require('model-transform');

var User = new keystone.List('User');
User.add({
	/* fields */
	// add a field you never want included in JSON data
	somethingPrivate: String
});

// add a virtual that you always want included in JSON data
User.schema.virtual('includeMe').get(function() {
	return true;
});

transform.toJSON(User, function(rtn) {
	// add individual virtual properties
	rtn.includeMe = this.includeMe;
	// delete private properties
	delete rtn.somethingPrivate;
	// return is optional becuase we've modified rtn by reference
	// return rtn;
});

User.register();
