I am new to RoR and have been trying to complete getting started link

http://guides.rubyonrails.org/getting_started.html

I'm getting couple of problems:

  1. I can't run rake db:create
  2. I can't run rake server

Workstation is Ubuntu 12.04, Rails 3.2.8, Ruby 1.9.3p194.

mukeshk@ubuntu:~/NetBeansProjects/rails_work/blog/config$ rake db:create
(in /home/mukeshk/NetBeansProjects/rails_work/blog)
rake aborted!
undefined method `active_record' for #<Rails::Application::Configuration:0x00000002080410>

(See full trace by running task with --trace)

Add this to your config/application.rb:

require "active_record/railtie"

  • Sounds like a broken configuration of Rails. Try using this tutorial, which is where I learnt Rails, and is exceedingly helpful and detailed. http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:up_and_running. Also check: http://stackoverflow.com/questions/6087919/rails-rake-dbcreate-error?rq=1 and http://stackoverflow.com/questions/6122966/ruby-on-rails-error-rake-dbcreate?rq=1 – Dane Balia Aug 15 '12 at 17:47
  • problem with >rails server resolved. I followed the guideline on http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:up_and_running – Mukesh kumar Aug 16 '12 at 18:50
  • problem with >rails server resolved. I followed the guideline on ruby.railstuturial.org only thing I changed was specifying specific version of gem in GemFile. I will update on > rake db:create issue shortly. thanks Dane Balia – Mukesh kumar Aug 16 '12 at 18:57
