How do I pass arguments from the parent task to the child task in Rake?

Question

I am writing a Rake script which consists of tasks with arguments. I figured out how to pass arguments and how to make a task dependent on other tasks.

task :pa         


        

Answer 1

Setting attributes seems to work like a charm too.

Just ensure the the task dependency is set to the task that sets the attributes you need.

# set the attribute I want to use in another task
task :buy_puppy, [:name] do |_, args|
  name = args[:name] || 'Rover'
  @dog = Dog.new(name)
end

# task I actually want to run
task :walk_dog => :buy_puppy do
  @dog.walk
end
