Core Data Buildpack

This is a Heroku buildpack for generating a REST web service from a Core Data model. It uses rack-core-data.

Usage

$ ls
Example.xcdatamodel

$ heroku create --stack cedar --buildpack http://github.com/mattt/heroku-buildpack-core-data.git

$ git push heroku master

-----> Core Data detected

This buildpack will detect your app if it includes a Core Data model (.xcdatamodel) file. Using rack-core-data, a REST web service that communicates with a Heroku Postgres dev database is generated according to the attributes and relationships of each entity in the data model:

Core Data Model API Endpoints
  • GET /artists
  • POST /artists
  • GET /artists/1
  • PUT /artists/1
  • DELETE /artists/1
  • GET /artists/1/songs

Limitations

The Core Data Buildpack is designed to encourage rapid prototyping, but should not be used on its own in production applications.

Rather, you are encouraged to create an application using Rack::CoreData directly, which allows you to extend the Core Data scaffolding with Rack applications, such as Rails or Sinatra, and middleware. Here's an example config.ru file:

config.ru

require 'bundler'
Bundler.require

DB = Sequel.connect(ENV['DATABASE_URL'])

run Rack::CoreData('./Example.xcdatamodeld')
