Can't deploy a basic Rails app on Heroku - ruby-on-rails

Question

First of all I am a newbie with Ruby on Rails so sorry if the question seem stupid.
I am following a tutorial about Heroku for Rails app and when I run git push heroku master and go to check on the actual website, I get this message:
We're sorry, but something went wrong. If you are the application owner check the logs for more information.
When I run heroku logs in my console, I get the following:

Looking at that, I couldn't find any reason that would cause a problem.
So far, here is how my database.yml file looks like:
development:
adapter: postgresql
database: tscope_dev
pool: 5
timeout: 5000
test:
adapter: postgresql
database: tscope_test
pool: 5
timeout: 5000
production:
adapter: postgresql
database: tscope_production
pool: 5
timeout: 5000
And my gemfile:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

I created the databse and did the migrations and also ran bundle install as well. It is the most basic application with just one controller generated with a scaffold.
Does anybody has any idea of what could be the problem? Even the smallest tip would help me since I really don't know what to look at right now.
If you need any futher information about my code, feel free to ask.
Thanks in advance :)
EDIT
Solved this issue by running heroku run rake db:migratein the console.
Turned out I haven't ran the migration on Heroku.

Answer 1

This line:
ActionView::Template::Error (PG::UndefinedTable: ERROR: relation "keywords" does not exist
suggests you haven't run your migrations on heroku.
To do that, in your console do:
heroku run rake db:migrate
