Rails

Hi Railsers,

I want to transport my codes written using ruby 1.8.7 on rails 2.3.5 to
ruby 1.9.2 on rails 3.0.0

Any help would do wonders…

I would recommend first experimenting with Rails 3. Have a look at
the Rails Guides and build some test apps. Also check you can deploy
to your production server.

Then the railscasts starting with
#225 Upgrading to Rails 3 Part 1 - RailsCasts may be
helpful.

Also obviously make sure you have a good set of automated tests before
you start and commit regularly to your version control system (git or
whatever) as you go.

Good luck

You may want to consider rebuilding your app under Rails 3 as there is
quite a bit of difference. I upgraded a project from Rails 2.3 to 3.0
and it was difficult.

There are several guides out there though for upgrading.

Hmm. Here’s the way I’ll probably do it when I upgrade my projects:

  1. Install RVM.
  2. Install Ruby 1.9.2 and Rails 3 under RVM, so I can flip back and
    forth between the two versions of the project.
  3. Run with Ruby 1.9.2/Rails 3 and see which tests fail.
  4. Pick one failing test and make it pass.
  5. Refactor as necessary.
  6. Repeat steps 4 and 5 till done.
  7. Tidy up anything else that needs it.
