In the latest Rails 7.1.2 my engines have stopped working with the following error
Zeitwerk::NameError:
expected file /home/jamie/Development/rails/comtech/r7/ccs_cms/engines/admin_dashboard/app/overrides/add_admin_dashboard_link_to_core_header.rb to define constant AddAdminDashboardLinkToCoreHeader, but didn't
It is my understanding that this is due to zeitwerk autoloading files in the engines app/overrides folder. Prior to the latest Rails release I have had the following code in an initializer in my engine.rb
class Engine < ::Rails::Engine
...
initializer "let the main autoloader ignore this engine's overrides" do
overrides = Engine.root.join("app/overrides")
Rails.autoloaders.main.ignore(overrides)
end
config.to_prepare do
overrides = Engine.root.join("app", "overrides")
Dir.glob("#{overrides}/**/*.rb").sort.each do |override|
load override
end
decorators = Engine.root.join("app", "decorators")
Rails.autoloaders.main.ignore(decorators)
Dir.glob(Engine.root.join("app", "decorators", "**", "*_decorator*.rb")) do |c|
Rails.configuration.cache_classes ? require(c) : load(c)
end
end
This has been happily working up until now and it follows the Documentation which shows the following example on ignoring and loading folders and files specifically overrides
# config/application.rb module MyApp class Application < Rails::Application
# ...
overrides = "#{Rails.root}/app/overrides"
Rails.autoloaders.main.ignore(overrides)
config.to_prepare do
Dir.glob("#{overrides}/**/*_override.rb").sort.each do |override|
load override
end
end end end
What is the solution to this now please? Or have I hit a Rails bug? Or have I just got it wrong somehow?, up to and including Rails 7.1 this was not an issue
Update It seems I have more than this to deal with. Upgrading to Rails 7.1.2 from Rails 7.1.1 seems to have caused a lot more issues than originally realised. Latest log from starting the rails server shows
