Rails 2.3风格的插件和弃用警告在Heroku中运行任务 [英] Rails 2.3-style plugins and deprecation warnings running task in Heroku

问题描述

DEPRECATION警告：我已经升级到Rails 3.2，并运行rake db：migrate，你在供应商/插件中有Rails 2.3风格的插件！在Rails 4.0中将会删除对这些插件的支持。将它们移出并将它们捆绑到Gemfile中，或者将它们作为lib / myplugin / *和config / initializers / myplugin.rb折叠到您的应用程序中。有关详情，请参阅发行说明： http://weblog.rubyonrails.org/2012/01/04/rails-3-2-0-rc2-has-been-released 。 （从/ app / Rakefile调用：7）

令人困惑的是我的 vendor / plugins 目录是空的 - 是否有另一个它引用的插件目录？

解决方案

你在使用Heroku吗？




Heroku将在Rails 3.x应用程序中注入插件。
为了避免在Rails 3中注入
，在
应用程序中包含rails_12factor gem。 （ Heroku Ruby支持 2013-10-26）


rails 4中的rails_12factor gem也是必需的。



如果这个gem不是出现在您的应用程序中，您将在部署期间收到
警告，并且您的资产和日志不会成为
功能。 （ Heroku上的Rails 4 2013-10-26）

2013-08最近，heroku总是在rails 3应用中注入插件，甚至包含推荐的gem应用。这是ruby buildpack的一个问题，并且已经通过 PR 11 进行修复，并于2013年合并， 08-06。

I'm upgrading to Rails 3.2, and running rake db:migrate gives me several errors of the form:

DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/01/04/rails-3-2-0-rc2-has-been-released. (called from at /app/Rakefile:7)

What's perplexing is that my vendor/plugins directory is empty -- is there another plugins directory that it's referencing?

解决方案

Are you using Heroku?

Heroku will inject plugins in Rails 3.x applications .. To avoid this injection in Rails 3, include the rails_12factor gem in your application. (Heroku Ruby Support 2013-10-26)

The rails_12factor gem is also required in rails 4.

If this gem is not present in your application, you will receive a warning while deploying, and your assets and logs will not be functional. (Rails 4 on Heroku 2013-10-26)

As recently as 2013-08, heroku always injected plugins in rails 3 apps, even apps with the recommended gems. This was an issue with the ruby buildpack, and was fixed by PR 11, merged on 2013-08-06.
