How to pass arguments into a Rake task with environment in Rails?

I am able to pass in arguments as follows:

desc "Testing args"
task: :hello, :user, :message do |t, args|
  args.with_defaults(:message => "Thanks for logging on")
  puts "Hello #{args[:user]}. #{:message}"
end

I am also able to load the current environment for a Rails application

desc "Testing environment"
task: :hello => :environment do 
  puts "Hello #{User.first.name}."
end

What I would like to do is be able to have variables and environment

desc "Testing environment and variables"
task: :hello => :environment, :message do |t, args|
  args.with_defaults(:message => "Thanks for logging on")
  puts "Hello #{User.first.name}. #{:message}"
end

But that is not a valid task call. Does anyone know how I can achieve this?

Just for completeness, here the example from the docs mentioned above:

   task :name, [:first_name, :last_name] => [:pre_name] do |t, args|
     args.with_defaults(:first_name => "John", :last_name => "Dough")
     puts "First name is #{args.first_name}"
     puts "Last  name is #{args.last_name}"
   end

Notes:

  • You may omit the #with_defaults call, obviously.
  • You have to use an Array for your arguments, even if there is only one.
  • The prerequisites do not need to be an Array.
  • args is an instance of Rake::TaskArguments.
  • t is an instance of Rake::Task.
