How can I run a ruby class from rake file?

问题 I want to run a ruby class from a sample.rake file. Consider myruby.rb is a ruby file. I want to run this from sample.rake like ruby myruby.rb 回答1: Adding to what @tobias has to say here you go with an example script sample content of myruby.rb puts "hello world" Create file called Rakefile task :default => [:test] task :test do ruby "my_file.rb" end Now if you invoke rake it should file up hello world text in console. Update It would make more sense if you wrap your call in a function call

rake aborted! undefined method `prerequisites' for nil:NilClass

问题 Spoiler: It was an outdated version of the rspec-rails gem! I encountered this error with any rake command issued from my rails project directory after moving my sqlite3 gem into a development block and then running 'rake db:migrate' to make sure everything still worked. Rake works fine elsewhere on my system. But any rake task I run in that directory gives me the following output with the trace: /Users/ianyoung/.rvm/gems/ruby-1.9.2-p290/gems/rspec-rails-2.0.0.beta.18/lib/rspec/rails/tasks

问题 This is my command bundle exec rake resque:work QUEUE="*" --trace I want to run this command on my server as a background process. please help me. 回答1: A method I often use is: nohup bundle exec rake resque:work QUEUE="*" --trace > rake.out 2>&1 & This will keep the task running even if you exit your shell. Then if I want to just observe trace output live, I do: tail -f rake.out And you can examine rake.out at any time. If you need to kill it before completion, you can find it with ps and

Run rake task from outside RAILS_ROOT

由 一个人想着一个人 提交于 2019-12-07 09:18:07
问题 My RAILS_ROOT is /usr/local/www/application/ If I run 'rake db:migrate RAILS_ENV=production" from within the RAILS_ROOT it works fine. However I can't seem to find a way to run the same command from outside the RAILS_ROOT. 回答1: Try: rake -f $RAILS_ROOT/Rakefile db:migrate RAILS_ENV=production # Assuming you set the environment variable. # Else, just replace $RAILS_ROOT by actual value 回答2: I think you need to re-think your question. When running rake without specifying a rakefile, it's going

How do I use the Clockwork Rails scheduler Gem?

问题 I'm having problems with the syntax for the Clockwork scheduler process. I'm actually having similar issues to what is discussed in this thread but never fully answered(How do I use Rails clockwork gem to run rake tasks?) My 'scheduler.rake' is working correctly when I test it with a 'heroku rake send_notifications'. My clock.rb process is working too as it will trigger every 30 seconds. However, I'm having issues with the clock.rb's syntax to correctly run the 'send_notifications' task in my

How to invoke rake with non-rake parameters

由 你说的曾经没有我的故事 提交于 2019-12-07 07:14:54
问题 I have a rake task that creates diagrams: task :diagram do `rake erd filetype=dot disconnected=true` end The execution of this task is quite slow and I guess it is because in the nested rake-invoke statement the whole rails environment is loaded again. I wanted to use Rake::Task['...'].invoke instead. But the erd task has some non-rake arguements ( filetype=dot etc.), which don't seem to work with the invoke method. Is there a way to pass those arguments to rake so that I can use the proper

heroku rake require 'rake/dsl_definition' fix not working + breaking local rake

由 落爺英雄遲暮 提交于 2019-12-07 07:08:49
问题 I'm having the same heroku rake issues described (and from what I can tell solved) in this question. When I try the fix (include require 'rake/dsl_definition' above require 'rake') I get the same 'uninitialized constant Rake::DSL' error from heroku + I get the error 'no such file to load -- rake/dsl_definition' from my local rake. Without incorporating the fix (using the standard rakefile) I can use rake on my local setup with no errors (with the same heroku error) I'm using rake version 0.8
