SolidusSupport

This gem contains common runtime functionality for Solidus extensions.

If you are looking for development tools instead, see solidus_dev_support.

Rails >= 5 introduced the concept of specifying what Rails version your migration was written for, like ActiveRecord::Migration[5.0]. Not specifying a version is deprecated in Rails 5.0 and removed in Rails 5.1. This wasn't backported to Rails 4.2, so we provide this helper to return the right parent class:

# On Rails 4.2
SolidusSupport::Migration[4.2] # returns `ActiveRecord::Migration`
SolidusSupport::Migration[5.0] # errors

# On Rails 5.0
SolidusSupport::Migration[4.2] # same as `ActiveRecord::Migration[4.2]`
SolidusSupport::Migration[5.0] # same as `ActiveRecord::Migration[5.0]`

There's no reason to use SolidusSupport::Migration[5.0] over ActiveRecord::Migration[5.0], but it is provided.

This extension provides a module that decorates Rails::Engine to seamlessly support autoloading decorators both with the classic autoloader and with Zeitwerk on Rails 6. In order to use it, just include the provided module in your Engine class:

module SolidusExtensionName
  class Engine < Rails::Engine
    engine_name 'solidus_extension_name'

    include SolidusSupport::EngineExtensions

    # ...
  end
end

If needed, also ensure to remove the original implementation of .activate:

def self.activate
  Dir.glob(File.join(root, "app/**/*_decorator*.rb")) do |c|
    Rails.configuration.cache_classes ? require(c) : load(c)
  end
end

config.to_prepare(&method(:activate).to_proc)

If you include EngineExtensions in your extension and structure your files according to the expected paths, they will be loaded automagically only when the relevant Solidus engines are available.

Here's what an example structure may look like:

• lib/views/backend: will only be added to the view paths when solidus_backend is available.
• lib/controllers/backend: will only be added to the controller paths when solidus_backend is available.
• lib/decorators/backend: will only be added to the decorator paths when solidus_backend is available.

The same goes for frontend and api.

We strongly recommend following this structure and making your extensions so that they're not dependent on anything other than solidus_core, only augmenting the functionality of the other engines when they are available.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
