Freezing Rails with Git

Now that the Ruby On Rails team has moved the codebase over to github, some of the standard rake tasks aren’t working the way that they used to. When it was on SVN, it was possible to type

rake rails:freeze:edge TAG=rel_2-0-1

p. and the appropriate version would be copied into your vendor/rails directory.

p. Now if you do that, rake downloads a zip of the edge release. Which is fine and all, but sometimes you don’t want to be on edge … like in any production site.

p. So, I found a screencast that goes through the process, but I thought I’d actually put the text into a post, mainly for my own reference more than anything else.

$ rails path_to_app

$ cd path_to_app

$ git init

$ git submodule add git:// vendor/rails
</pre >

	p. At this point, git will effectively clone the repository, so that you can then choose one of the branches to "freeze" to. Type "git tag" to get a list of all the available tagged branches. Choose the one you want and type

@$ git checkout v2.1.0@

	p. And that's it. Slightly more involved than the old way, but still none too shabby.
