ruby-on-rails – Rails控制台无法连接到数据库,但rake任务可以

我可以运行任何rake db：*成功但是当我运行rails console时我无法连接到db.

我该如何解决？该应用程序运行正常.所以我认为是一个rails控制台问题.

控制台输出：

deployer:/home/rails$RAILS_ENV=production bundle exec rake db:migrate
  ActiveRecord::SchemaMigration Load (3.2ms)  SELECT "schema_migrations".* FROM "schema_migrations"

deployer:/home/rails$echo $APP_DATABASE_PASSWORD
[redacted database password]

deployer:/home/rails$RAILS_ENV=production bundle exec rails console
Running via Spring preloader in process 25038
Loading production environment (Rails 4.2.6)
2.3.0 :001 > User.connection
PG::ConnectionBad: fe_sendauth: no password supplied

database.yml的

default: &default
  adapter: postgresql
  encoding: unicode
  pool: 5
  host: localhost
  username: rails
  password: <%= ENV['APP_DATABASE_PASSWORD'] %>

production:
  <<: *default
  database: production
  username: rails
  password: <%= ENV['APP_DATABASE_PASSWORD'] %>

环顾四周,我发现ActiveRecord :: Base.configurations的密码为：nil.为什么服务器进程会读取密码,但控制台却没有？

我将ActiveRecord :: Base.configurations添加到初始化程序中.初始化时,密码存在.

在控制台上ActiveRecord :: Base.configurations按预期返回所有信息,密码除外.我甚至已经重新加载默认变量.的/ etc /默认/麒麟

RAILS_ENV =生产包exec rails console上的ActiveRecord :: Base.configurations

App_DATABASE_PASSWORD上的ActiveRecord :: Base.configurations =密码RAILS_ENV =生产包exec rails console

RAILS_ENV =生产包exec rails服务器上的ActiveRecord :: Base.configurations
