This guide covers upgrading a 0.60.x Spree store, to a 0.70.x store. This guide has been written from the perspective of a blank Spree 0.60.x store with no extensions.

If you have extensions that your store depends on, you will need to manually verify that each of those extensions work within your 0.70.x store once this upgrade is complete.

Upgrade Rails

Spree 0.60.x depends on Rails 3.0.12, whereas Spree 0.70.x depends on any Rails version from 3.1.1 up to 3.1.4. The first step in upgrading Spree is to upgrade the Rails version in the Gemfile:

gem 'rails', '3.1.12'

For more information, please read the Upgrading Ruby on Rails Guide.

Upgrade Spree

For best results, use the 0-70-stable branch from GitHub:

gem 'spree', :github => 'spree/spree', :branch => '0-70-stable'

Run bundle update rails and bundle update spree and verify that was successful.

Remove debug_rjs configuration

In config/environments/development.rb, remove this line:

config.action_view.debug_rjs = true

Remove lib/spree_site.rb

This file is no longer used in 0.70.x versions of Spree.

Set up new data

To migrate the data across, use these commands:

rails g spree:site
rake db:migrate

The Asset Pipline

With the upgrade to Rails 3.1 comes the asset pipeline. You need to add these gems to your Gemfile in order to support Spree’s assets being served:

group :assets do
  gem 'sass-rails',   '~> 3.1.5'
  gem 'coffee-rails', '~> 3.1.1'

  # See for more supported runtimes
  # gem 'therubyracer'

  gem 'uglifier', '>= 1.0.3'

gem 'jquery-rails', '2.2.1'

Along with these gems, you will need to enable assets within the class definition inside config/application.rb:

module YourStore
  class Application < Rails::Application

  # ...

  # Enable the asset pipeline
  config.assets.enabled = true

  # Version of your assets, change this if you want to expire all your assets
  config.assets.version = '1.0'

Verify that everything is OK

Click around in your store and make sure it’s performing as normal. Fix any deprecation warnings you see.
