I did the following.

  1. I changed the rails version to 2.2.2 in environment.rb -
    RAILS_GEM_VERSION = ‘2.2.2’ unless defined? RAILS_GEM_VERSION

  2. from project path I ran a rake task $ rake rails:update

  3. when i run $ ruby script/about. I get the following output. Please
    help me. What next to do - I am converting my rails app from 1.1.6 to
    2.2.2.

    • config.breakpoint_server has been deprecated and has no effect.

No, you probably want to migrate to Rails 2.3, which is the current
version.

Please state me the steps what I need to do.

Search this forum for detailed information. In brief:

  • Create a new branch in your version control system for the upgrade.
  • Change the RAILS_GEM_VERSION.
  • Run rake rails:upgrade (or whatever it’s called).
  • Update plugins as necessary.
  • See which tests fail.
  • Fix the code so tests pass.

1.1.6 to 2.3 will be a huge jump. You will probably find it easier to
do several smaller upgrades – say, 1.1 to 1.2, then 1.2 to 2.0, and so
on.

Thanks in advance,
Raju

A useful thing I found when I just completed (mostly) the same trip was to create a dummy project (rails -d mysql tst) using the version of rails I wanted to go to.  I was then able to compare the config files one by one to see what had changed.  There are a lot of changes in config files in that jump and the changes are not automaticly made by the rake task.  You will have to go in and see how each file changed and decide what you want to do.  In a lot of the cases you will just replace your current version of the file with a copy of the later version.  In some cases you will have some reason to do differently just make sure you understand what the differences are and why you want what you want.  It is  not a rote task!

thanks for your reply,

when I run the rake task $ rake rails:update . My default javascript
files ie

  1. prototype.js
  2. controls.js
  3. effects.js
  4. dragdrop.js

Have changed, can I use the new version of these files, is there
anything depreciated compared to the older version.

Thanks in advance,
Raju

  1. acts_as_tree as tree has been move to a separate plugin, you will
    need to install this:
  1. I wouldn’t expect you to have any issues with upgrading to
    Prototype. Do you have much custom javascript code using Prototype?

Thanks for your reply Nicholas,

Now the only problem I am facing in my application is “form_remote_tag”

How to use form_remote_tag in 2.2.2

I am trying to use it in this way in 2.2.2

<%= form_remote_tag({:url => {:controller => ‘some_controller’,
:action => ‘some_action’},
:update => ‘some_div’,
:loading =>
“Effect.Appear(‘indicator’);”,
:complete => “Effect.Fade(‘indicator’);”,
:html => {:id => ‘some_id’ }
}) do %>

-----------------All Text fields & checkboxes etc etc…

<%end%>

before it was (in 1.1.6)

<%= form_remote_tag({:url => {:controller => ‘some_controller’,
:action => ‘some_action’},
:update => ‘some_div’,
:loading =>
“Effect.Appear(‘indicator’);”,
:complete => “Effect.Fade(‘indicator’);”,
:html => {:id => ‘some_id’ }
}) %>

-----------------All Text fields & checkboxes etc etc…

<%end_form_tag%>

Please help me to use form_remote_tag in rails 2.2.2

Thanks in advance,
Raju
