问题 Have just installed whenever gem https://github.com/javan/whenever to run my rake tasks, which are nokogiri / feedzilla dependent scraping tasks. eg my tasks are called grab_bbc, grab_guardian etc My question - as I update my site, I keep add more tasks to scheduler.rake. What should I write in my config/schedule.rb to make all rake tasks run, no matter what they are called? Would something like this work? every 12.hours do rake:task.each do |task| runner task end end Am new to Cron, using

问题 I attempted to use a solution posted here: GitLab v5.0 git push problems to fix the ssh keys getting out of sync problem. However, when I run the rake command as both root & git users on the repository server I get the following message: root@gitlab /home/git# rake gitlab:shell:setup RAILS_ENV=production --TRACE No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb) /usr/local/lib/ruby/gems/1.9.1/gems/rake-0.9.2.2/lib/rake/application.rb:495:in `raw_load_rakefile' /usr

问题 How do I run a rake script automatically every time I save a file in Visual Studio? I can create a batch file that wraps the command. And I'd like to trigger it on CTRL + S . But, Visual Studio 2012 doesn't have macros. JP Boodhoo has done it in many of his screen casts, but hasn't shared the implementation. FYI, my rakefile looks like this require 'albacore' desc 'Build Solution' msbuild :Build do |msb| msb.properties :configuration => :Release msb.targets :Clean, :Build msb.solution =

问题 I have a rake task that calls functions like this: namespace :blah do task :hello_world => :environment do logger.info("Hello World") helloworld2 end end def helloworld2 logger.info("Hello Again, World") end I want the log output to a custom log, and I really don't want to have to pass a log reference every time I make a function call. I found this somewhere (can't find it again): def logger @@logger ||= Logger.new("#{RAILS_HOME}/log/blah.log") end But this does not work for me and I am not

问题 My dev team needs to more precisely run rake tasks. There are certain tasks that need to be only run once after a specific code change. Without getting too specific, it would be like needing to update certain existing users records after a new business rule for new users is implemented in the code. We like how migrations use a db table for logging. Is there a similar tool for rake tasks? Can we hack Rails'/ActiveRecord's migrations system for rake tasks? We'd prefer not to mix db-related

问题 I want to pass different arguments to every method and need to run all methods parallel using rake task Here is rake task calling example Rake::Task['test:sync'].invoke(user.id, user.address) Rake::Task['test:sync'].invoke(user.id, user.address) Rake::Task['test:sync'].invoke(user.id, user.address) I have seen the multitask example like this multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do puts "All Copies Complete" end Here they are calling with the task name alone. But in my

问题 I had a working (and working well) ImageScience install, that did some simple resizing to various dimensions of images, and then copying them to different directories. All very simple. This small and simple routine was in a rake task. Upon update to Rails 3, this rake task will still work (it does some AR inserts and audio encoding as well), but the image_science require fails with a message like this, "require on /home//.ruby_inline/Inline_ImageScience_cdab.so failed" I've ruled out a duff

问题 I have a gem that exists simply to collect several engines together for ease of implementation, as well as to provide a few utility methods to all of the included engines. One such utility method is a rake task to release new versions of all of the collected engines. My problem is that, when I run code that should execute in the context of one of the collected engines it all (git commands, file system manipulation, etc.) works, except for the rake build command. For some reason, that command

问题 I just found a bug in one of the rake tasks shipped with Rails. Is there a way to monkey patch a rake task? 回答1: Yes. You can do something like this: Rake::Task['doc:app'].clear and then define your own task namespace :doc do task :app do # work your magic end end 来源： https://stackoverflow.com/questions/2412627/how-to-monkey-patch-a-rake-task-shipped-with-rails
