rails4_upgrade Build Status

Helps you more easily upgrade to Rails 4. A work in progress, I'm simply shipping something of a minimum viable product to attract others to contribute.

Inspired by rails_upgrade which helped upgrade applications from Rails 2 to Rails 3.

Written in part to complement the book Upgrading to Rails 4.

Installation

Upgrade to Ruby 1.9.3 if your application does not already use it. Rails 4 requires Ruby 1.9.3, and rails4_upgrade uses 1.9-only syntax and semantics.

Add to Gemfile:

gem 'rails4_upgrade', github: 'alindeman/rails4_upgrade'

Usage

Run rake rails4:check:

$ rake rails4:check

** GEM COMPATIBILITY CHECK **
+--------------------+----------------------+
| Dependency Path    | Rails Requirement    |
+--------------------+----------------------+
| draper 0.18.0      | actionpack ~> 3.2    |
| draper 0.18.0      | activesupport ~> 3.2 |
| simple_form 2.0.4  | actionpack ~> 3.0    |
| simple_form 2.0.4  | activemodel ~> 3.0   |
+--------------------+----------------------+

Contributing

I'm open to accepting pull requests that improve the functionality of the gem.

If there's an upgrade procedure that can be automated or semi-automated, let's discuss it. Open an issue.

Ideas:

  • Recommending versions of gems that may be compatible with Rails 4
  • Removing deprecated configuration options
  • Adding newly required or recommended configuration options
