Answer 1

Rake::Task['reklamer:orville'].invoke

or

Rake::Task['reklamer:orville'].invoke(args)

Answer 2

In rails 4.2 the above methods didn't work.

1. Go to the Terminal.
2. Change the directory to the location where your rake file is present.
3. run rake task_name.
4. In the above case, run rake iqmedier - will run only iqmedir task.
5. run rake euroads - will run only the euroads task.

6. To Run all the tasks in that file assign the following inside the same file and run rake all

   task :all => [:iqmedier, :euroads, :mikkelsen, :orville ] do #This will print all the tasks o/p on the screen 
   end
   

Answer 3

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

Answer 4

Sometimes Your rake tasks doesn't get loaded in console, In that case you can try the following commands

require "rake"
YourApp::Application.load_tasks
Rake::Task["Namespace:task"].invoke

Answer 5

Have you tried rake reklamer:iqmedier ?

My custom rake tasks are in the lib directory, not in lib/tasks. Not sure if that matters.

Answer 6

If you aren't sure how to run a rake task, first find out first what tasks you have and it will also list the commands to run the tasks.

Run rake --tasks on the terminal.

It will list the tasks like the following:

rake gobble:dev:prime             
rake gobble:dev:reset_number_of_kits                                    
rake gobble:dev:scrub_prod_data

You can then run your task with: rake gobble:dev:prime as listed.
