downgrading rails project from 3.2.1 to 2.3.3 - ruby-on-rails

My first Rails project deploy, and I've run into an issue.
The project is Rails 3.2.1, Ruby 1.9.3
Yesterday, I was given the hosting access, and they're having Rails 2.3.3, Ruby 1.8.7
If I'll decide to still deploy the app there, what changes do I need to make to it?
Specifically, I'm interested in Gemfile changes.
Here's my current gemfile:
source 'https://rubygems.org'
gem 'rails', '2.3.3'#'3.2.1'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'haml-rails'
gem 'haml'
gem 'omniauth-twitter'
What do I need to change? How do I look-up all the required dependencies and gems versions for old Rails versions?

Downgrading from 3.x to 2.3 is the dumbest thing you can do in your case.
Install gems locally, or ask your hosting company support department — they have to help.
If you can't, save your time — use Heroku, OpenShift or any other hosting company.

Upgrade from Rails 3.2 to Rails 4

I have an application in Rails 3.2 which is ready to deploy. I am wondering should I upgrade it to Rails 4 or not. I also not sure about which of the gems might give issues with while upgrading.
Below is my Gemfile with several common gems.

I started working on this application last year (Nov 2012) after reading this great book at
http://ruby.railstutorial.org/. I have also checked out what's new in Rails 4 like strong parameters and it's all very tempting to try an upgrade.
But I am concerned about compatibility of these gems and effort it may take.
I need some advice from experienced guys in the community or someone who has tried upgrading before I move ahead.
I uploaded your gemfile to Ready for Rails 4, and it appears that you only have a couple gems that are not ready and one gem that is unknown. For some of the gems listed that do not have notes, I would suggest checking out their GitHub page (if they have one), and see if the gem has been updated recently on rubygems, just to confirm whether or not the gem works.
This brief handbook was worth every cent in our recent 3.2 to 4 migration.
https://leanpub.com/upgradetorails4
https://github.com/alindeman/upgradingtorails4
It lists in details how to handle gem upgrades, as well as individual details (with clear examples) of what's changed and how to manage your current Rails app through the upgrade.
To address your gem-specific concerns: Almost all our 40+ gems, except perhaps 5, had active either Rails 4 releases (or Github branches for Rails 4), or worked just fine with Rails 4 when left intact.
Having a healthy unit/functional test suite in your codebase would be vital for your confidence in the upgrade being successful.
The asset pipeline has changed a bit, so you'll need to upgrade those gems. I had to use a fork of ransack in the context of active_admin, but you might be fine.
I'd recommend that you create a branch, bump to Rails 4, and see what happens. It took me a day or two to upgrade from 3.2 to 4 a couple weeks ago on a fairly small (but production-with-customers) application. The upgrade guide is pretty solid.

Installing Less in Ruby - Windows

I'm on Windows and i'm Trying to install The Flat UI Pro which need's Twitter Bootstrap Rails 3.1.
But whenever i try to install The Less Stylesheets, i'm getting a lot of weird errors about therubyracer gem an the V8 file.
I need to run
rails generate bootstrap:install less
which gives me the error
[WARNING] Please install gem 'therubyracer' to use Less.
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/less-2.3.2/lib/less/java_script/v8_context.rb:2:in `require': cannot load such file -- v8 (LoadError)
The server doesn't start also
My Gem File
source 'https://rubygems.org'
gem 'rails', '3.2.13'
gem 'jquery-rails'
gem 'twitter-bootstrap-rails'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'less-rails'
end
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'therubyracer-heroku', :platform => :ruby
end
If someone has experience or has installed Twitter Bootstrap for Rails 3.1 Asset Pipeline before please give me a helping hand :) Thank you
you can not install twitter-Bootstrap with less file on Window machine because , Window does not support twitter-bootstrap-less library l.e ( libV8 , exec.js , python , error) that not work on Window .
if you want to run your project on window machine than used "Bootstrap gem" instead of 'twitter-bootstrap-rails gem' .
Otherwise used the Ubuntu OS it is best suited for any Ruby on Rails Application with solve dependency of your GemFile easily . and you used "less-rails", and "twitter-bootstrap-rails" easily and not come any issue with libV8.

How can I resolve these Rails gem dependecies after adding rmre 0.0.4?

I made a new rails 3.2.8 app and added:
gem "rmre", "~> 0.0.4"
to this new gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.8'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'mysql2'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem "rmre", "~> 0.0.4"
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
Running bundle install yields:
Bundler could not find compatible versions for gem "erubis":
In Gemfile:
rmre (~> 0.0.4) ruby depends on
erubis (~> 2.6.6) ruby
rails (= 3.2.8) ruby depends on
erubis (2.7.0)
I tried commenting out the version numbers and even removing the gems related to asset management. Still, I can't seem to arrive at a combination of gem versions that work here. It's the first time I've run into this sort of situation and I am not sure what else I might do to try out the rmre gem with a version of rails that is at least 3-point-something.
Is there a clever way to search for a workable dependency resolution here? If there is not a gem version configuration that meets the recommended dependencies, is there a least-bad approach to pursue?
Many thanks!
You might try contacting the rmre gem author to see if they would be willing to loosen the dependency restriction, so that it's not tied to such a narrow erubis version. Forward compatibility is part of what gem authors need to maintain if they want their gem to continue to work with the latest versions of rails. – normalocity Nov 2 at 1:31

Worked.
Download the zip file from the page. Then execute the gem command. Worked for me. Incredible program.

rails 3.1 sphinx search hosting *thinking sphinx*

Firstly, Im a big fan of sphinx search. Thanks to sphinx.
Now my question is,
We are ready with a rails 3.1 app which uses sphinx search for full text searching.
Now, I know heroku is the best when it comes to rails hosting. It does not have support
for sphinxsearch, I hear.
If any of you know the right place to host a rails 3.1 app with sphinx search please
guide me.
I will mention the other things that Im using in my rails 3.1 app as listed in my gem
file.

Thank you so much.
Actually, Heroku does support Sphinx through the Flying Sphinx add-on. Otherwise, any decent VPS should work for you. Linode, in particular, has a pretty good reputation.

running rails 3.2 / mongoid app on heroku fails

I'd like to now if anybody could help me with my heroku deployement.
I've set up my Rails 3.2 app with the following Gemfile
source 'https://rubygems.org'
gem 'rails', '3.2.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'mongoid'
gem 'bson_ext'
gem 'mongoid_slug'
gem 'heroku'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem "compass", ">= 0.12.alpha"
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
And I have run the rails g mongoid:config command
From the heroku support, I've added the mongolab extension and changed the mongoid.yml evironnement variables to MONGOLAB_URI
When I then deploy the app, it doesn't run on heroku.
I'm not sure what is going on, but i get this error message in the Heroku logs:
WARNING: Invalid .gemspec format in '/app/.bundle/gems/ruby/1.9.1/specifications/actionmailer-3.2.0.gemspec'
2012-01-29T19:13:46+00:00 app[web.1]: Could not find activemodel-3.2.0 in any of the sources
here is the full log file:
https://gist.github.com/1700231
has anybody experienced the same issue? I'm not sure if the problem comes from my set up or if I need to add something to rails to work with mongoid?
Cheers.
It's been a bit of pain int the b*tt, but I'm finally there.
http://railsapps.github.com/rails-heroku-tutorial.html
is the right place to go to deplay rails 3.2 on heroku.
This said my head hurt, not too much fun to get so many hurdles when one wants to learn.
Octopress looks fine at the moment I tell you :)
Alright let's keep going
