I have been testing out Rails 3 beta4, but want to create a test application in Rails 2.3.8.
So, i installed the Rails version that i wanted, sudo gem install rails -v=2.3.8. Now when i try to create my application, using rails myTestApp -v=2.3.8, I get the rails help screen. Looking over it, I can't seem to find the option to specify the version of rails that I want to target.
rails new APP_PATH [options]
-G, [--skip-git] # Skip Git ignores and keeps
-b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL)
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
# Default: /Users/silliemunkie/Developer/.rvm/rubies/ruby-1.8.7-p248/bin/ruby
[--edge] # Setup the application with Gemfile pointing to Rails repository
[--dev] # Setup the application with Gemfile pointing to your Rails checkout
[--skip-gemfile] # Don't create a Gemfile
-d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
# Default: sqlite3
-O, [--skip-activerecord] # Skip ActiveRecord files
-J, [--skip-prototype] # Skip Prototype files
-T, [--skip-testunit] # Skip TestUnit files
-m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL).
-s, [--skip] # Skip files that already exist
-f, [--force] # Overwrite files that already exist
-p, [--pretend] # Run but do not make any changes
-q, [--quiet] # Supress status output
-v, [--version] # Show Rails version number and quit
-h, [--help] # Show this help message and quit
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
