generator administrate:install fails if ActionCable is disabled

[namiwang]

repro:

1. initialize new rails app with --skip-action-cable
2. install and try to init administrate

incorrect behavior:

> rails generate administrate:install
[WARNING] Could not load generator "generators/administrate/install/install_generator". Error: uninitialized constant ActionCable.
/Users/user/.asdf/installs/ruby/3.2.2/lib/ruby/gems/3.2.0/gems/turbo-rails-2.0.4/app/channels/turbo/streams_channel.rb:34:in `<main>'

Oh, that's a pain, thanks for reporting it.

Which version of Administrate are you using? Which of Rails?

[namiwang]

The latest stable ones I think. I can confirm later but I doubt it's related to specific versions. Maybe related to new loading mechanism from rails 7 with zeitwerk?

[nickcharlton]

Yeah, it could be! If you could confirm that'd be great.

[namiwang]

Just confirmed with latest stable versions (rails 7.1.3.2, administrate 0.20.1), full trace:

rails generate administrate:install

Could not find generator 'administrate:install'. (Rails::Command::CorrectableNameError)
Did you mean?  administrate:views
Run `bin/rails generate --help` for more options.

[dbelling]

This workaround in hotwired/turbo-rails#601 might be helpful?

[pablobm]

I can't reproduce 🤔 This is what I tried:

$ rails new --skip-action-cable no_action_cable
$ cd no_action_cable
$ bundle add administrate
$ ./bin/rails generate model thing name code amount:integer
$ ./bin/rails db:migrate
$ ./bin/rails generate administrate:install

The gem versions are as you list:

$ cat Gemfile.lock | grep -E '^    (rails|administrate) \('
    administrate (0.20.1)
    rails (7.1.3.4)

Is there something else in you app that I might be missing?
