mongoose-custom-fields

Dynamically extend your Mongoose.js schemas with unstructured custom fields.

Installation

$ npm install mongoose-custom-fields

mongoose-custom-fields does not require the mongoose module directly but expects you to have it installed.

Usage

Adding mongoose-custom-fields to your schema

mongoose-custom-fields uses Mongoose's built-in schema pluggability to extend your existing schemas.

var customFields = require('mongoose-custom-fields');

var PostSchema = new Schema({ /* ... */ });
PostSchema.plugin(customFields);

var Post = mongoose.model('Post', PostSchema);

Saving & updating custom fields

You can save custom fields to your objects with one simple method call to your objects.

var post = new Post();

post.customField('tags', [ 'simple', 'mongoose', 'fields' ]);
post.customField('comments', false);

post.save(function(err) {
	// Do other cool stuff
});

Accessing custom fields

After fields have been saved, you can access them with the same method in your object.

Post.findById(req.query.id, function(err, post) {
	var tags = post.customField('tags');

	// Do other cool stuff
});

You can also get a list of currently saved custom properties with the customKeys virtual property.

Post.findById(req.query.id, function(err, post) {
	var properties = post.customKeys;

	// properties will be [ 'tags', 'comments' ]
});

Removing existing custom fields

You can remove saved custom fields by setting their value explicitly to null. Note that falsey values do not remove the field.

Post.findById(req.query.id, function(err, post) {
	post.customField('comments', null);
});

Testing

We use the mocha testing framework. To run tests, first install the module with development dependencies.

$ npm install

You can run tests through npm or through mocha. Both will have the same result.

$ npm test
$ mocha test
