I'm working on a Rails engine that allows the implementer to put classes in app/snippets.
From within the engine, I want to instruct the host Rails app to auto reload classes in app/snippets upon each request so that the implementer doesn't have to restart the server when making changes.
I understand there's a config.to_prepare initialization event I can hook into, but I can't get access to the app.root like I an in an initializer block. In other words:
initializer 'something' do |app|
# I need app.root to derive app/snippets
end
config.to_prepare do
# Can't get app.root from here
end
How can I auto reload classes in app/snippets upon each request?
