Implement rake db:rollback STEP=n inside rakefile

I'm trying to combine a bunch of rake tasks like this: 

desc 'Resets the database'
task :reset do
  Rake::Task["db:rollback"].invoke
  Rake::Task["db:migrate"].invoke
  Rake::Task["db:seed"].invoke
end

I don't know how to do rollback with STEP=n inside my Rakefile

Solution

  • STEP is an environment variable, so if you do this:

        desc 'Resets the database'
    task :reset do
      ENV['STEP'] = '1000' 
# The number has to be greater than
# or equal to the number of your migrations.

      Rake::Task["db:rollback"].invoke
      Rake::Task["db:migrate"].invoke
      Rake::Task["db:seed"].invoke
    end

    that should work
