Glass

Glass is a lightweight Rails Engine that is built to do all the heavy lifting from serving an API in your Rails Application.

Features

CRUD for your models without a Controller
Integrates quickly for all client-side Javascript frameworks (Ember, Backbone, Angular)

Installation

Add this line to your application's Gemfile:

gem 'glass-api', require: 'glass'

And then execute:

$ bundle

Or install it yourself as:

$ gem install glass-api

And then run:

rails generate glass:install

This generator will install Glass. It will also add an initializer in config/initializer/glass.rb

Glass.configure do |config|
  config.models = ['User']
  config.app_name = 'Test App'
  config.format = :json
end

It will modify your app/assets/javascripts/application.js, adding:

//= require glass

It will modify your config/routes.rb, adding:

mount Glass::Engine => '/api', as: 'glass'

Mongoid

class Model
  include Mongoid::Document
  def self.column_names
    self.fields.collect { |field| field[0] }
  end
end

Usage

Ruby

rails server

Javascript

The following usage examples makes use of the Glass API given that you have a User model in your Rails app and you have configured the Glass gem to expose it.

Find

Finds a list of records in a model with 'Foo' as name.

glass.User.find({
  name: 'Foo'
}, function (res, error) {
  if (!error) {
    // Do something with res
  }
});

Find All

The following usage example finds all users.

glass.User.findAll(function (res, error) {
  if (!error) {
    // Do something with res
  }
});

Create

Create a new user record.

var user = {
  name: 'Jaune Sarmiento',
  email: '[email protected]'
};

glass.User.create(user, function (res, error) {
  if (!error) {
    // Do something with res
  }
});

Update

Update the user with id == 1 and update its name to Joko.

// Given our create() function returns the user object with 1 as id
var user = {
  id: 1,
  name: 'Joko'
};

glass.User.update(user, function (res, error) {
  if (!error) {
    // Do something with res
  }
});

Delete

Delete a user record with id == 1.

glass.User.delete({id: 1}, function (res, error) {
  if (!error) {
    // Do something with res
  }
});
