[Application de tableau d'affichage SNS] (https://github.com/kkoji/rails-lecture/tree/current_user_method) J'ai le droit de faire.

Rails série 5 Ruby 2.4.5 mysql2

Enfin j'essaye de me déployer sur heroku

Jusqu'à ce que vous déployez Rails sur Docker avec Heroku Je suis bloqué en essayant d'utiliser MySQL avec Heroku Référez-vous à, essayez

En tant que flux, Ajouter clearDB en tant que module complémentaire Définir dans la configuration (changer en mysql2) Connexion CLI heroku Connectez-vous au conteneur Heroku heroku create~~ heroku container:push web heroku container:release web heroku run rails db:migrate heroku open heroku run rails assets:precompile heroku config:add RAILS_ENV=production (Je ne comprends pas le pipeline d'actifs)

Cependant, une erreur d'application s'est produite lors de l'ouverture d'heroku et aux journaux heroku --tail

C'est sorti.

plus loin, Heroku run rails console c

Running via Spring preloader in process 18
WARNING: Spring is running in production. To fix this make sure the spring gem is only present in `development` and `test` groups in your Gemfile and make sure you always use `bundle install --without development test` in production
Loading production environment (Rails 5.0.7.2)

pour cette raison, Modifier l'installation du bundle avec Dockerfile

FROM ruby:2.4.5
RUN apt-get update -qq && apt-get install -y build-essential nodejs
RUN mkdir /app
WORKDIR /app
COPY Gemfile /app/Gemfile
COPY Gemfile.lock /app/Gemfile.lock
RUN bundle install --without development test
COPY . /app

Je l'ai réécrit, mais ça n'a pas guéri.

Hmmm faible ...
