Heroku — “We're sorry, but something went wron

Question

Hi I'm pretty new on Heroku. I have finished part of my app. Currently I'm working locally, but I want to deploy to Heroku. When I typed heroku logs I got this:

And when I type heroku open it shows me "We're sorry, but something went wrong." Does anyone know why this happens?

Answer 1

1. migrate the database on server.

2. try precompiling your asset pipeline

Answer 2

When you create your heroku stack do this instead of just heroku create:

heroku create --stack cedar

and make sure you do this before you push to heroku:

heroku run rake db:migrate

Answer 3

assets should be precompiled add to your config/application.rb

config.assets.initialize_on_precompile = false

Answer 4

You need to compile your assets locally first.

Take a look here: https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar

Try the below before pushing to Heroku.

RAILS_ENV=production bundle exec rake assets:precompile
