对于 ruby on rails 3，在生产模式下不调用 Rake 任务

Question

From a controller:-

call_rake :parse_venue, :venue_list_id => venue_list.id


def call_rake(task, options = {})
   options[:rails_env] ||= Rails.env
   args = options.map { |n, v| "#{n.to_s.upcase}='#{v}'" }
   system "rake #{task} #{args.join(' ')} --trace 2>&1 >> #{Rails.root}/log/rake.log &"
end 

In development mode this rake task is triggered.. But in case of production mode its not triggered.

PS:- Inspired from rake in background, railscast . There is nothing in rake.log file in production mode

Answer 1

Try the following system call:

system "#{args.join(' ')} rake #{task} --trace 2>&1 >> #{Rails.root}/log/rake.log &"

Answer 2

Verify that "rake" is in the $PATH of the user running your web server / app server
