Answer 1

당신의 config/application.rb 다음을 제거합니다

require 'rails/all'

을 다음과 같이 :

이

require "rails" 
# Pick the frameworks you want: 
require "active_model/railtie" 
require "active_job/railtie" 
# require "active_record/railtie" 
require "action_controller/railtie" 
require "action_mailer/railtie" 
require "action_view/railtie" 
require "action_cable/engine" 
require "sprockets/railtie" 
require "rails/test_unit/railtie" 

이로드 active_record을 사용하지 않습니다.

그런 다음 당신은 제거하거나 등 config/application.rb, config/environments/* 아래에있는 모든 환경 파일, config/initializers/ 아래에있는 모든 초기화가 포함 config 디렉토리,

에서 모든 파일에 config.active_record.*의 모든 항목을 주석 처리합니다 마지막으로 을 기반으로하는 app/models 디렉토리 아래의 모든 모델을 제거해야합니다.
