Question

如何编写一个rake任务，将捆绑安装然后rake db：migrate然后rake db：seed。

namespace 'install' do
  'bundle install'
  'rake db:migrate'
end

Answer 1

这应该可以，但考虑使用Capistrano / Chef进行部署：

namespace :install do
  task :db_reset do
    # bundle install - I do not believe attempting this in a rake file
    # is recommended as one would need to ensure it is run in your application
    # directory and rvm has loaded correct version of ruby/gemsets (.rvmrc required)
    Rake::Task['db:migrate'].invoke
  end
end

或者，您可以设置shell别名来执行

bundle install && bundle exec rake db:migrate && bundle exec rake db:seed
