Why is my custom rake task in lib/tasks not discovered in Rails 3?

Build-in rake tasks work fine, but my new custom one, in Project/lib/tasks/payments.rb doesn't get loaded:

namespace :payments  do
  desc "Tally payments at the end of the month"
  task :compute => :environment do
    BillingPeriod.compute_new_period
  end
end

$ rake payments:compute
(in /Users/rob/Code/Apps/skyfarm)
rake aborted!
Don't know how to build task 'payments:compute'

It works fine if I load the file application.rb:

require 'lib/tasks/payments.rb'

...but it breaks other things:

$ rails s
./lib/tasks/payments.rb:1: undefined method `namespace' for main:Object (NoMethodError)
Solution

  • Change the file extension from .rb to .rake.
