ruby-on-rails – 用于安装仅执行一次的gem迁移的Rake任务

gems = %w(gem1 gem2 gem3)
namespace :gems do
  namespace :install do
    desc "Runs install:migrations for all gems"
    task :migrations do
      gems.each do |gem_name|
        print "nInstalling migrations for the #{gem_name} gem...n"
        Rake::Task["#{gem_name}:install:migrations"].invoke
      end
      print "nnGem migrations installed."
    end
  end
end

实际上只运行第一组迁移,无论我使用的gems / gem order / random调用reenable？

Installing migrations for the gem1 gem...
Copied migration whatever from gem1
Copied migration whatever from gem1
Copied migration whatever from gem1
Copied migration whatever from gem1

Installing migrations for the gem2 gem...
(nothing)

Installing migrations for the gem3 gem...
(nothing)

Gem migrations installed.
