Rails website documentation for an older version

Rails has beautiful documentation on their guides and t开发者_StackOverflow社区heir website: http://guides.rubyonrails.org/association_basics.html

I am taking on an application that uses Rails 2.2.2 but the documentation on the rails site is for the latest version. How could I find the 2.2.2 documentation?

In other words check out how Django does it: https://docs.djangoproject.com/en/dev// You can click which version it is and the documentation will adjust accordingly?

I do see that RailsBrain.com has an previous release docs, but they only display the API and I am looking for the nice site(ie. how current release site looks but for 2.2.2)

Thanks.

http://apidock.com/rails/ has a version scale to see documentation for different versions.

Also official guides have branches for any older versions, e.g. Rails 2.3: http://guides.rubyonrails.org/v2.3.11/, Rails 3.2: http://guides.rubyonrails.org/v3.2.13/

Try this one:

http://railsguides.heroku.com/

It's a collection of the guides of each version.

Btw, Its old one is based on 2.3.5 but it will be much easier than reading the new one.

If you're looking for an offline solution, I strongly recommend Dash.app -for Mac OS- and Zeal. -for Windows & Ubuntu- By downloading docsets you'd like, you can start using API docs offline.
