capistrano deploy：迁移不存在

这是我的第一个rails项目，与capistrano合作非常愉快 .

我目前的问题是我需要运行cap deploy：migrate和cap：deploy：migration作为单独的任务 . 我认为应该有一个上限：迁移，它结合了这些 .

这是我的终端输出：

kris$ cap staging deploy:migration
      triggering load callbacks
     * executing `staging'
    the task `deploy:migration' does not exist

我的设置是使用多阶段，并使用RVM capistrano插件 .

这是我的宝石文件：

source 'https://rubygems.org'

gem 'rails', '3.2.1'

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'mysql2'
end

group :test do
  gem 'sqlite3'
  gem 'ZenTest'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

#formtastic 2.2 breaks activeadmin
gem "formtastic", "~> 2.1.1"
gem "activeadmin", "~> 0.4.3"

# meta_search required for activeadmin
gem 'meta_search'

gem 'jquery-rails'
gem "paperclip", "~> 3.0"

gem 'acts_as_list'
 gem 'unicorn'

# Deploy with Capistrano

 gem 'rvm-capistrano'

gem 'mail'

这是我的配置/部署文件：

任何有关 deploy:migration 被破坏的帮助都会非常有帮助 . 谢谢 .
