Rails 7 has removed ActiveSupport::Dependencies. How should reloading be done now?

[mileslane]

#358
https://github.com/ruby-grape/grape#reloading-api-changes-in-development
We have:

 ActiveSupport::Dependencies.explicitly_unloadable_constants += [
    'GrapeAPI::V1::RootEndpoint',
    'GrapeAPI::RootEndpoint'
  ]

Any updates on this?

NoMethodError: undefined method `explicitly_unloadable_constants' for ActiveSupport::Dependencies:Module

It sounds like it's time to move away from grape to something like pure API with VueJS, or Turbo from Hotwire

The method ActiveSupport::Dependencies.explicitly_unloadable_constants has been removed in Rails 7, which is why you're seeing a NoMethodError. This method was part of Rails' older autoloading system, but Rails 7 fully relies on the Zeitwerk autoloader, which does not use manually unloadable constants.

To fix this, you need to migrate away from explicitly_unloadable_constants and rely on Zeitwerk’s autoloading, which handles reloading of constants automatically
