无法在Heroku上部署Rails应用

Question

I have been trying to deploy a simple rails app onto heroku and i have been completely unsuccessful.

I am working on the Mac terminal using the Viking Code School prep work to walk through the "Railsfest Installation". This is the exact link I have been following:

http://docs.railsbridge.org/installfest/deploy_a_rails_app

My problem is that it looks like I have deployed the app successfully, but if you go the link at:

https://powerful-river-94011.herokuapp.com

you can clearly see that "something is wrong"... as per heroku's standard output.

I have been working every solution to try to pin down the problem between the commands:

gem install bundler
bundle install --without production

I've set up the file correctly in the routes.rb file and I've also committed all changes to git with:

git add .
git commit -m "Updates for heroic deployment"

and I've pushed it all through successfully with:

git push heroku master

before pushing successfully i worked through a litany of errors from adding a Procfile to the test app's root path, changing gem files to include the version of ruby being used, to updating bundler with the explicit version i wanted, to updating Xcode, and anything else you can find online about this.

I've reached the extent of what i know to solve this and what is left is to read through the logs, but i don't know how to do so yet.

below are the log files for this issue, and if you can help me pinpoint the area that is causing my headache i would be greatly appreciative.

ill probably even set a bounty!!!

see logs:

Answer 1

Any time you see an error like this:

PG::UndefinedTable: ERROR: relation "drinks" does not exist

it probably means that you haven't run your migrations. So you probably missed the:

heroku run rake db:migrate --app ...

step when deploying. Most of us end up writing little scripts to do all the necessary steps in the right order so that we can simply say bin/deploy and not have to worry about it.
