Using in Rails engines

If the application UI consists of multiple frontend application, you'd probably like to isolate their building too (e.g. if you use different frameworks/versions). Hence we needed our webpack(-er) to be isolated too: separate package.json, dev server, compilation process.

You can do this by adding another Webpacker instance to your application.

This guide describes how to do that using Rails engines.

Step 1: create Rails engine.

CRUD with Ember (+ Data)

Ember's official documentation describes a number of low-level APIs, but doesn't talk much about how to put them together. As a result, a simple task such as creating a simple CRUD application is not obvious to a newcomer.

What this does

This is the initial code. Improvements are likely to be had.

This creates an activity feed that can track updates, destroys, creates in a MySQL database.
This is inspired by part of the "public_activity" gem.
For Updates, what changed will be automatically stored as a hash.
Bootstrap's usage is assumed, as is Devise's "current_user". ActiveRecord must be used as well. These can easily be changed however.
