Migration to rails2 rails3

dubstep · July 27, 2011, 7:56am

Good evening everyone,

I went to change the Rails version of my project, and saw that many
things have
stopped working.

As the “rake routes”, which is giving the following error:
rrmartins rodrigo @: ~ / Documents / vota_prato $ rake routes
rake aborted!
no such file to load - tasks / rails

(See full trace by running task with - trace)

What do you think you can be?

thanks

Install rails upgrade plugin, it will convert your old routes,
environment
and other config files to new Rails 3 format.
Read the instructions on plugin’s homepage for more info.

when I run the first command you gave me appears the help of the rails,
and
apparently does not install, and the second an error.

I put down the errors and the versions of ruby and rails.

rodrigo@rrmartins:~/Documentos/vota_prato2$ sudo ruby script/rails
plugin
install git://github.com/rails/rails_upgrade.git
ruby: No such file or directory – script/rails (LoadError)
rodrigo@rrmartins:~/Documentos/vota_prato2$ sudo rails plugin install
git://

Usage:
rails new APP_PATH [options]

Options:
-r, [–ruby=PATH] # Path to the Ruby binary of your choice
# Default: /usr/local/bin/ruby
-d, [–database=DATABASE] # Preconfigure for selected database
(options:
mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
# Default: sqlite3
-b, [–builder=BUILDER] # Path to an application builder (can be a
filesystem path or URL)
-m, [–template=TEMPLATE] # Path to an application template (can be
a
filesystem path or URL)
[–dev] # Setup the application with Gemfile
pointing
to your Rails checkout
[–edge] # Setup the application with Gemfile
pointing
to Rails repository
[–skip-gemfile] # Don’t create a Gemfile
-O, [–skip-active-record] # Skip Active Record files
-T, [–skip-test-unit] # Skip Test::Unit files
-J, [–skip-prototype] # Skip Prototype files
-G, [–skip-git] # Skip Git ignores and keeps

Runtime options:
-f, [–force] # Overwrite files that already exist
-p, [–pretend] # Run but do not make any changes
-q, [–quiet] # Supress status output
-s, [–skip] # Skip files that already exist

Rails options:
-v, [–version] # Show Rails version number and quit
-h, [–help] # Show this help message and quit

Description:
The ‘rails new’ command creates a new Rails application with a
default
directory structure and configuration at the path you specify.

Example:
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.

rodrigo@rrmartins:~/Documentos/vota_prato2$ rails -v
Rails 3.0.9
rodrigo@rrmartins:~/Documentos/vota_prato2$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]

Can you attach your config/environment.rb file and Gemfile?

If you have already upgraded your application to Rails 3, then you have
to
use the new syntax to install the plugin:

rails plugin install git://github.com/rails/rails_upgrade.git

or

ruby script/rails plugin install
git://github.com/rails/rails_upgrade.git

Everything looks good here.
What all did you do when upgrading from rails 2 to rails 3?
There are a lot of changes in the script and config folders between the
two
versions.

Generate a new rails3 app, copy over everything from the script folder
into
script folder of your app.
Then try installing the plugin again with:

ruby script/rails plugin install
git://github.com/rails/rails_upgrade.git

No need to use sudo with the command, unless your application directory
is
owned by root.

Chirag, Thank you,

Differences between the Rakefile to rails2 rails3.

Rails2 the Rakefile:
require(File.join(File.dirname(FILE), ‘config’, ‘boot’))
require ‘…’

Rails3 the Rakefile:
require File.expand_path(‘…/config/application’, FILE)
::Application.load_tasks
