Fix for Heroku in production, changing Gemfile and Rakefile

Gemfile

# Fix for error: `ActionView::Template::Error ('twitter/bootstrap.less' wasn't found.`

# Gems inside of assets aren't required in production, but we need bootstrap in production
# So pull the bootstrap gem outside of assets
# You also need to remove `app/assets/stylesheets/bootstrap.css.less` if you haven't already.

gem 'twitter-bootstrap-rails'

group :assets do
  ..
end

group :production do
  gem 'pg'
end

group :development, :test do
  gem 'sqlite3'
end

General.rb

# If you're not seeing errors and nothing is working, be sure to have migrated your db in heroku
# After pushing to git, pushing to heroku, run `heroku run rake db:migrate`
# You can also run `heroku run rake db:seed` if you have a `seeds.rb`

Rakefile

# Fix for error: `no such file to load -- rspec/core/rake_task`

# Heroku builds apps without the Gemfile's development/test groups, which is where we have rspec installed 
# So when Heroku runs the Rakefile it expects rspec even though it doesn't exist in production
# That's why we need to add an unless to make sure we only run rspec outside of production

unless Rails.env.production?
  begin
    require 'rspec/core/rake_task'

    task :default => :spec

    RSpec::Core::RakeTask.new("spec:acceptance") do |t|
      t.rspec_opts = "--tag acceptance"
    end
  end
end
