在本地，但没有工作，我有一个的工作完全罚款在当地一个Rails应用程序，但是当我推它在Heroku它显示“应用程序错误” enter image description here Rails应用在生产

我试图访问Heroku的应用程序日志，但没有什么在那里，但是当我试图heroko上运行控制台它开始给这个错误：

根据gem文件，sqlite gem不会在生产环境中加载，只能进行测试和开发。将宝石添加到生产中。 – dbugger

为什么你首先使用不同的数据库进行生产和开发？ – RSB

在您的database.yml文件，改变生产数据库使用PostgreSQL作为Heroku的不支持sqlite3的。

例如：

production: 
    database: example_production 
    adapter: postgresql 
    host: localhost 
    password:

要设置SQLite作为默认的数据库使用此代码

default: &default 
    adapter: sqlite3 
    pool: 5 
    timeout: 5000

所以用这个代码是越来越设置为sqlite的，因为你是包括defualt值，这在heroku上不起作用，因为你不能在heroku上使用sqlite。

production: 
    <<: *default 
    database: db/production.sqlite3

您应该更改database.yml文件中的生产数据库值。

production: 
    adapter: postgresql 
    pool: 5 
    timeout: 5000 
    database: app_name
