如何在路轨上的红宝石上贴上补丁? [英] How do you apply a patch to ruby on rails?

问题描述

我想应用此线程中提到的action_mailer修补程序，但是我以前从未应用过该修补程序，而且我不确定它们是如何工作的: https://rails.lighthouseapp.com/projects/8994/tickets/2263

I'd like to apply the action_mailer patch mentioned in this thread but I have never applied a patch before and I'm not sure how these work: https://rails.lighthouseapp.com/projects/8994/tickets/2263

我的动作邮件程序gem在这里:/opt/ruby-enterprise-1.8.6-20090421/lib/ruby/gems/1.8/gems/actionmailer-2.3.2

My action mailer gem is here: /opt/ruby-enterprise-1.8.6-20090421/lib/ruby/gems/1.8/gems/actionmailer-2.3.2

我认为我需要进入该目录并运行patch命令...类似这样的东西?

I assume I need to go to that directory and run the patch command...something like this?

cd /opt/ruby-enterprise-1.8.6-20090421/lib/ruby/gems/1.8/gems/
wget https://rails.lighthouseapp.com/attachments/108548/0001-Fix-implicit-multipart-mailer-views-when-RAILS_ROOT.patch
patch < 0001-Fix-implicit-multipart-mailer-views-when-RAILS_ROOT.patch

我还不清楚的一件事是，补丁文件指向"actionmailer"目录，而我的被称为"actionmailer-2.3.2"

One thing I'm not really clear on also is that the patch file refers to the "actionmailer" directory but mine is called "actionmailer-2.3.2"

推荐答案

您通常不希望修补gem资源本身.您可能希望将宝石冻结到${RAILS_ROOT}/vendor/rails中，然后在本地应用补丁.

You typically don't want to patch the gem source itself. You probably will want to freeze the gems into ${RAILS_ROOT}/vendor/rails, and then apply the patch locally.

从您的$ {RAILS_ROOT}目录中，将所有rails gem都转储到供应商/rails中

From your ${RAILS_ROOT} dir, dump all of your rails gems into vendor/rails

rake rails:freeze:gems

应用补丁

  cd vendor/rails/ 
  patch -p1 < 0001-Fix-implicit-multipart-mailer-views-when-RAILS_ROOT.patch
