Erd

A Rails engine for drawing your app's ER diagram and operating migrations

Requirements

  • Rails 4.0, 3.2, or 3.1

  • Graphviz

Installation

Add 'erd' gem to your existing app's Gemfile:

gem 'erd'

Bundle it:

% bundle

Usage

Browse at your localhost:3000/erd

Features

  • Erd draws an ER diagram based on your app's database and models

  • You can drag and arrange the positions of each model

  • You can operate DB schema manipulations such as `add column`, `rename column`, `alter column`, `create model (as well as table)`, and `drop table`

  • Then, Erd generates migration files on the server

  • And you can run each migration on your browser

TODO

  • Fix buggy JS

  • drop column (need to think of the UI)

  • stop depending on rails-erd and Graphviz

  • tests

  • cleaner code (the code is horrible. Please don't read the code, though of course your patches welcome)
