나는 레일스 튜토리얼 서적에서 레일스를 배우려고 노력하고있어 가능한 최상의 경험을 얻으려고 노력할 수있다. 지금 나는 쉽고 똑바로되어야하는 무언가에 붙어 있습니다. 우리는 여전히 매우 시작 부분에 작은 "장난감 애플 리케이션"것 같은 아주 기본적인 트위터를 만드는레일 튜토리얼 2.2 : 퓨마 서버
, 우리는 사용 : 다음하지 틀리지 및 경우
$ rails generate scaffold User name:string email:string
사용자 테이블을 생성하려면 :
기존 테이블 구조를 업데이트하는 것으로 추측됩니다 (확실하지는 않지만 나중에 모든 것이 설명됩니다). 내가 한하는 쉽게 구분할 탭에서
$ rails server -b $IP -p $PORT
이 오류 가지고 :
마지막으로 우리는이를 실행 해야하는~/workspace/toy_app$ rails server -b $IP -p $PORT

는 아무것도 손상을? 내가 잘못 했니? 나는에 (응용 프로그램 폴더에) 퓨마를보고 기억 파일을 확인 가서는 보석 파일입니다 :
gem 'puma', '3.4.0'
그리고 puma.rb 파일 (꺼내서 코멘트) :
threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }.to_i
threads threads_count, threads_count
port ENV.fetch("PORT") { 3000 }
environment ENV.fetch("RAILS_ENV") { "development" }
plugin :tmp_restart
언급 한 모든 파일을 넣을 예정 이었지만 코드가 많았습니다. 유용한 정보가 있으면 게시하고 가능한 쓸모없는 코드로 스팸하지 않으려 고합니다.
