Migration Builder

Migration Builder is an interactive command-line tool that builds Rails migrations. The goal is for Migration Builder to be able to generate 95% of common migration types without having to google the Rails migration syntax.

Note: Migration Builder is currently in an EXTREMELY early stage of development, so set your expectations accordingly.

Usage

To start the Migration Builder prompt, run:

$ rails mb:start

Installation

Add this line to your application's Gemfile:

group :development do
  gem 'migration_builder', git: 'https://github.com/jasonswett/migration_builder'
end

And then execute:

$ bundle

Or install it yourself as:

$ gem install migration_builder

Capabilities

Migration Builder features currently include:

Adding columns on existing tables (including null constraints)
Removing columns from existing tables
Renaming existing tables
Adding unique indexes (including compound unique indexes)
Creating new tables
Dropping existing tables

Feedback and contributing

This is my first swing at OSS and I have no idea how it works. If you find a bug (which is really easy at this stage!) or have a feature idea (also easy since Migration Builder does almost nothing so far!), feel free to open an issue on this repo.
