rake-task

问题 I have a rake task : task :kill_process do system %q(ps -ef | awk '{if($8~"java" || $8~"glassfish" || $8~"ruby" || $8~"god" || $8~"couch"){printf("Killing : %s \n",$2);{system("kill -9 "$2)};}}') end This is basically killing processes.

问题 I'm sure I miss some basic thing. I had a correctly working app in dev environment. Than I had some modifications that I cant correctly explain (with the migrations and tried to insert seed_dump gem).

A little logic about the application: The application allows users to "take the challenge" and read a book a week over the course of a year. It's pretty simple: users sign up, create the first book that they will read for their first week, then can enter what they're going to read next week. After they've "queued" up next week's book, that form is then

问题 I am writing a Rake task. I want to trigger it every last sunday of every month at 11 pm. How can I schedule this using the Whenever gem in Ruby on Rails? I have my rake task in the following location: app/lib/tasks/my_task.rake task :create_entries => :environment do puts "Hello" end 回答1: I don't think there's a rule for "last x day of the month" but you can always put an extra if test inside the block: every :sunday, :at => '11pm' do #if the month is different a week from now, we must be in
