Heroku与红宝石在轨道上和Mongoid

Question

I am working on a project in ROR with Mongoid. The app is working fine when running rails offline server but when I deploy it on Heroku it is throwing me this error

2016-02-03T16:34:08.405268+00:00 heroku[web.1]: Process exited with status 1

I am not using ActiveRecords but using Mongoid so please suggest me any solution to this problem.

Thanks in advance

Answer 1

There are many reason cause app crash in heroku for example heroku server missing some require gem in your app. use
$ heroku logs --tail
to view exactly what happen in heroku server.
