我有一个小型rails应用程序，它接收用户的起始和结束地址，并根据它返回他们可以采取的总线列表。我是rails的新手，我第一次将应用程序部署到了heroku。在heroku上部署应用程序后，我能够成功迁移表，并运行种子来填充数据。然后像往常一样，我输入了一个开始和结束地址。点击提交后，我收到消息告诉我检查我的日志。所以我运行heroku日志，这就是我得到的。

我不确定这个错误究竟是什么。
以下是我的database.yml文件
# MySQL. Versions 5.0+ are recommended.
#
# Install the MYSQL driver
# gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
# gem 'mysql2'
#
# And be sure to use new-style password hashing:
# http://dev.mysql.com/doc/refman/5.0/en/old-client.html
#
default: &default
adapter: postgresql
encoding: utf8
pool: 5
username: root
password:
# socket: /tmp/mysql.sock
development:
<<: *default
database: BingBus_development
# 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:
<<: *default
database: BingBus_test
# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
# DATABASE_URL="ec2-23-21-140-156.compute-1.amazonaws.com"
#
# You can use this database configuration with:
#
# production:
# url: <%= ENV['DATABASE_URL'] %>
#
production:
<<: *default
database: BingBus_production
username: BingBus
password: <%= ENV['BINGBUS_DATABASE_PASSWORD'] %>
日志似乎也在运行我的查询但由于某种原因存在错误。我不知道为什么。我知道的这么近，但我错过了一些东西。如果有人能在这里帮助我，我将非常感激。

假设您正在使用 Heroku Postgres ，请删除此部分：
production:
<<: *default
database: BingBus_production
username: BingBus
password: <%= ENV['BINGBUS_DATABASE_PASSWORD'] %>
Heroku设置数据库并自动配置rails应用程序。

Heorku不关心你的database.yml他们自动创建他们的数据库你可以在设置DATABASE_URL的配置变量中看到它来识别连接。
