I was thinking about writing a Yet another interactor/service/use case/command gem for myself. But I ended up using pure Ruby. If I want, I can create different results, eg. `WaitingApproval = Data.define(:user)`.
![Screenshot of this code:
class UserCreator
Success = Data.define(:user)
Failure = Data.define(:reason, :user)
def initialize(attributes:)
@attributes = attributes
end
def create
user = # do stuff
return Success[user:] if user.save
Failure[reason: :invalid_record, user:]
end
end
def create
case UserCreator.new(attributes:).create
in UserCreator::Success(user)
redirect_to user_path(user)
in UserCreator::Failure(user)
render Users::NewPage.new(user:)
end
