Rails how to run rake task

You can run Rake tasks from your shell by running:

rake task_name

To run from from Ruby (e.g., in the Rails console or another Rake task):

Rake::Task['task_name'].invoke

To run multiple tasks in the same namespace with a single task, create the following new task in your namespace:

task :runall => [:iqmedier, :euroads, :mikkelsen, :orville] do
  # This will run after all those tasks have run
end
