如何在rake任务中使用ActiveRecord模型和参数

Question

In a rake task I'm using argument like this:

namespace :foo do
  task :bar, [:arg1] do |t, args|
    puts args[:arg1]
  end
end

And I want to use ActiveRecord model, I add => :environment like this:

namespace :foo do
  task :bar => :environment, [:arg1] do |t, args|
    puts args[:arg1]
  end
end

And when I run rake foo:bar[1] , it ends up with error:

rake aborted!
SyntaxError: /home/ironsand/rails_project/lib/tasks/foo.rake:2: syntax error, unexpected keyword_do_block, expecting =>
  task :bar => :environment, [:arg1] do |t, args|

What should I to use ActiveRecord model and argument same time in a rake task?

Answer 1

Correct syntax is:

namespace :foo do
  task :bar, [:arg1] => :environment do |t, args|
    puts args[:arg1]
  end
end
