UnknownTypeNameError: name=ApplicationRecord

generate_rbs_for_model rake task generates RBSs only for not abstract classes. Because it refers to RDBMS's schema information, and abstract classes don't have a schema.

RBS Rails isn't responsible for abstract classes. If you need RBS for them, you can write the RBSs by hand or generate them with rbs prototype rb that rbs gem provides.

UnknownTypeNameError: name=::ActiveStorage

Currently RBS Rails haven't supported ActiveStorage yet. And the priority is not high.
So, if you need the type of ActiveStorage, you can write it yourself.

By the way, ActiveStorage does not inherit ActiveRecord::Base, and it is not a class.

UnknownTypeNameError:** name=::ActsAsTaggableOn

What is ActsAsTaggableOn? Is it a gem? https://github.com/mbleigh/acts-as-taggable-on
RBS Rails isn't responsible for gems except for rails.
So, you can write RBSs for them yourself. Or you can find gems from the official RBS repo (but now it has only a few gems).

By the way, I think we need more documentation to introduce RBS Rails and Steep. I'll work on it. #68

I'm running into very similar errors when trying to introduce RBS to my Rails app:

I think rbs_rails should definitely create a signature file for ApplicationRecord at the very least, since that's something every Rails app will have. I'd definitely like better docs for how to set this up :)

Thank you for your work, @pocke!

[pocke]

@connorshea Thanks for your feedback!

I think it needs to generate all superclasses of ActiveRecord models, including ApplicationRecord.
For example:

# Ruby files
class User < ApplicationRecord
end

class Article < AnotherApplicationRecord
end

# RBS files
class ApplicationRecord < ActiveRecord::Base
end

class AnotherApplicationRecord < ActiveRecord::Base
end

class User < ApplicationRecord
end

class Article < AnotherApplicationRecord
end

I'll implement it with #77 because #77 also needs to generate superclasses.

By the way, I guess you need to require some library, such as Mutex_m, Logger, etc.

And I haven't generated ActiveStorage's RBS yet, so you need to write the RBS by hand for now 🙏.
