Ruby on Rails 4 - Using Rake on Heroku


Ruby on Rails 4 - Using Rake on Heroku

To fix the issue you can do I was moving my app from Nitrous.io which uses SQLite to Heroku for production which uses Postgres, and I got the following error. 2 things, I don't get why it won't do change_column, and I definitely don't understand their "hint". How can I go about implementing properly? , Try:
code :
change_column(:messages, :sender, 'integer USING CAST(sender AS integer)')

With these it helps Do you have Cygwin installed? This article (in Japanese) mentions this error and points to this SO question which suggests you make sure Cygwin and possibly ncurses is installed. A comment there links to this article which may also have useful information.
It looks like the issue is that heroku is looking for the tput command in your shell which is not available (which I believe comes with ncurses).
code :
group :production do
  gem "pg", "~> 0.11.0"
end

help you fix your problem On Heroku you could set up scheduler:
https://addons.heroku.com/scheduler
code :
desc "describe your task"
task :clear_old_posts => [:environment] do
  posts = Post.where(created_at: <= Time.now - 1.month)
  posts.each do |post|
    post.destroy
  end
end

I wish this helpful for you I'm currently running a ruby app with:
code :
task :scale_down do
  heroku = Heroku::API.new(api_key: ENV['HEROKU_API_KEY'])
  heroku.post_ps_scale(ENV['APP_NAME'], 'worker', 0)
end

fixed the issue. Will look into that further Precompile
To give you some clearer definitions - Heroku isn't the only system which requires you to "precompile" your assets. Asset precompilation is a pre-requisite of most Rails production environments, as it allows you to serve static assets (files) - perfect for speed & efficiency
