[英]Heroku + Rails: NoMethodError (undefined method `/' for nil:NilClass)
问题描述
My app is running perfectly locally, but I'm unable to bring it up after pushing to Heroku. 
我的应用程序在本地运行良好，但是在推送到Heroku后无法启动。
Here are the logs: 以下是日志：

As per the chat session with OP, 根据与OP的聊天会话，
The error was on below line: 错误在以下行中：
@companysponsored = (finance.salary / 12) * (@getcompanysponsored.to_f / 100)* (@getcompanymatchupto.to_f / 100)
@getcompanymatchupto was set AFTER this call. 在此调用之后设置了@getcompanymatchupto 。 Hence, its value was nil above. 因此，其值高于零。 Suggested to define @getcompanymatchupto before using it. 建议在使用@getcompanymatchupto之前定义它。
