A Rails engine for drawing your app's ER diagram and operating migrations
Rails 4.2, 4.1, 4.0, 3.2, or 3.1
Add 'erd' gem to your existing app's Gemfile:
Browse at your localhost:3000/erd
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
Fix buggy JS
drop column (need to think of the UI)
stop depending on rails-erd and Graphviz
cleaner code (the code is horrible. Please don't read the code, though of course your patches welcome)
