Question

我刚安装了heroku然后安装了postgresql，但现在我收到了这个错误。为什么我需要密码？我的密码是什么？

我花了几个小时寻找可行但却无法正常工作的东西（我在窗户上）：

这是我的database.yml

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: postgresql
  encoding: unicode
  database: myapp_development
  pool: 5
  username: postgresql
  password: 
  host: localhost

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: postgresql
  encoding: unicode
  database: myapp_test
  pool: 5
  username: postgresql
  password: 
  host: localhost

production:
  adapter: postgresql
  encoding: unicode
  database: myapp_production
  pool: 5
  username: postgresql
  password: 
  host: localhost

这是我的宝石文件

知道我能做什么吗？

Answer 1

根据this page，您可以使用此命令：

$ heroku config | grep HEROKU_POSTGRESQL
HEROKU_POSTGRESQL_RED_URL: postgres://user3123:passkja83kd8@ec2-117-21-174-214.compute-1.amazonaws.com:6212/db982398

给出的URL是postgresql connection字符串，其中包含嵌入的用户名和密码（本例中为user3123和passkja83kd8）。

Answer 2

在test文件的development和database.yml部分下的本地计算机上，您应该将username更改为您登录的用户名。 rails生成器使它与您的appname相同，但不起作用。在生产中，部署到heroku时无关紧要，并且设置会自动更改。

fe_sendauth：localhost：300上没有提供密码
