问题 I have a set of rake tasks where I need to invoke capistrano at some point. Edwin Goei's blog suggests shelling out to capistrano via "sh". Is there a simpler way?

If you want to call them from a rake task, though, you need to do a little extra work. task :deploy require 'rubygems' require 'capistrano' require

问题 I've written a very simple rake task to try and locate the source of this problem. namespace :foo do task bar: :environment do puts 'RUNNING' end end When executed in the console rake foo:bar the output is: RUNNING RUNNING This occurs when I execute any rake task. Has anyone encountered anything like this before? EDIT The above rake task is all that is written in that .rake file. Here is the Rakefile currently being used. require File.expand_path('../config/application', __FILE__) OurApp:

问题 AS the guides, the command used to prepare test database is bundle exec rake db:test:prepare However, I have found that following command also works & created the test db for me. bundle exec rake test:prepare Wanted to know if this is a valid command, if yes.

Hence it's a shortcut, wrapper, whatever you want to call it.
