问题描述
这个答案似乎已经以各种方式回答，但没有一个看起来符合我的确切问题。我正在使用来自RailsApps的应用程序 github/RailsApps/rails-devise-pundit
该应用程序在我的本地Ubuntu 14.04机器上完美工作，但是当我将其部署到Heroku时，我的应用程序应该在页面上出现应用程序错误已经开始。我运行'heroku日志'，但无法确定具体问题是什么。以下是我的日志以及我的Gem文件。任何帮助将不胜感激。
这是我的记录

/app/config/initializers/devise.rb:13如果你仍然有这个代码13
config.mailer_sender ='no-reply @'+ Rails.application。 secrets.domain_name然后原因是 Rails.application.secrets.domain_name 是零。在Heroku中，你必须通过einvironment变量设置秘密，并在生产部分的erb parsed secrets.yml中读取它们。
eg ＃secrets.yml 开发： 域名：example 生产：域名：<％ = ENV ['DOMAIN_NAME']％>
This answer seems to have been answered in various ways, but none that seemed to fit my exact issue. I am using the app from RailsApps github/RailsApps/rails-devise-pundit
The app works perfectly on my local Ubuntu 14.04 machine, but when I deploy it to Heroku, I get an 'application error' on the page my app should have been started. I ran 'heroku logs' but can't be sure what the exact issue is. Below is my log as well as my Gem file. Any help would be greatly appreciated. Thank you.

This is what really caused the error
/app/config/initializers/devise.rb:13If you still have this code in 13
config.mailer_sender = 'no-reply@' + Rails.application.secrets.domain_nameThen the reason is that Rails.application.secrets.domain_name is nil. On Heroku you have to set the secrets through einvironment variables und read them in the erb parsed secrets.yml in the production section
e.g #secrets.yml development: domain_name: example production: domain_name: <%= ENV['DOMAIN_NAME'] %>
