railsでmodelの作り方を教えてください

Question

以下のようにrailsでmodelを作成してmigrationしたのですが、作成したmodelを使おうとすると
uninitialized constant QuestionAnswer (NameError)
となります
どこか、やり方間違ってますか？

user@Users-MBP-70 gmail_test % rails g model QuestionAnswer category:string question:text answer:text
Running via Spring preloader in process 36520
      invoke  active_record
      create    db/migrate/20220613132121_create_question_answers.rb
      create    app/models/question_answer.rb
      invoke    test_unit
      create      test/models/question_answer_test.rb
      create      test/fixtures/question_answers.yml
user@Users-MBP-70 gmail_test % rails db:migrate                                                      
Running via Spring preloader in process 36542

Loading development environment (Rails 6.1.6)
irb(main):001:0> QuestionAnswer.new
(irb):1:in `<main>': uninitialized constant QuestionAnswer (NameError)

ちなみにmodelクラス自体はは作成されてます

class QuestionAnswer < ApplicationRecord
end
