When writing Rake tasks, to get access to all classes (such as the User
model in this example) in your app’s environment, you need to depend on the :environment
task shown as follows:
task :post_user => :environment do end_time = Time.new start_time = end_time - 60 #subtract 60 seconds until start_time > end_time start_time = start_time + 15 #increment 15 seconds puts "Posting #{start_time}" uesr = User.new(:user_id => 817, :timestamp => start_time) user.save end end
