Error: "uninitialized constant CASClient" when installed as Rails plugin

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try installing CAS client at <AppFolder> "ruby script/plugin install 
http://rubycas-client.googlecode.com/svn/trunk/rubycas-client"
2.
3.

What is the expected output? What do you see instead?
I see, <appFolder>\vendor\plugins is not a working copy and seems to be 
updating other files.

What version of the product are you using? On what operating system?
Ruby: 186, Rails : 2.0.2, Windows XP - Professional

Please provide any additional information below.

 Added CASClient::Frameworks::Rails::Filter.configure(
    :cas_base_url => "https://cas.example.foo/"
  ) in config/environment.rb
and before_filter CASClient::Frameworks::Rails::Filter to 
app/controllers/application.rb

Now run the server as ruby script/server, server is throwing erros saying 
uninitialized CAS Client errors

I'm having a hard time reproducing your problem. I tried it on a fresh XP 
machine and
it worked fine. Here's what I did:

1. Installed the latest version of Rails: `gem install -y rails`
2. Created a fresh Rails application: `rails my_test`
3. Configured the database for the my_test app.
4. Generated a test controller: `ruby script\generate controller test`
5. Installed the RubyCAS-Client plugin: `ruby script/plugin install
http://rubycas-client.googlecode.com/svn/trunk/rubycas-client`
6. Configured the CAS client in config\environment.rb.
7. Added the filter to the Test controller: "before_filter
CASClient::Frameworks::Rails::Filter"

Now when I try to visit http://localhost:3000/test it works fine, redirecting 
me to
the CAS login page.

Can you repeat the steps above and let me know if you're still having problems?

Reading over your bug report, it sounds like something may be wrong with the 
way the
plugin is getting installed. Can you be a bit more specific about what hapens 
when
you run:

  ruby script/plugin install 
    http://rubycas-client.googlecode.com/svn/trunk/rubycas-client

Also you mention that it is not a "working copy". If you're looking to check 
out a
subversion repo then you need to use the -x flag with your plugin install:

  ruby script/plugin install -x 
    http://rubycas-client.googlecode.com/svn/trunk/rubycas-client

If all else fails, you can try installing the client as a rubygem:

  gem install rubycas-client

If you install as a gem, make sure you add "require 'rubycas-client'" to your
environment.rb file.

Matt,
Thank you very much for quick response.
I just followed your steps 1 to 7 and now CAS plug in installed successfully. I 
don't see "not a working copy" error any more.
but still getting "`load_missing_constant': uninitialized constant CASClient
 (NameError)".

Here I am my configurations:
config/environment.rb
===================
# Be sure to restart your server when you modify this file

# Uncomment below to force Rails into production mode when
# you don't control web/app server and can't set it the proper way
# ENV['RAILS_ENV'] ||= 'production'

# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.0.2' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
  # Settings in config/environments/* take precedence over those specified here.
  # Application configuration should go into files in config/initializers
  # -- all .rb files in that directory are automatically loaded.
  # See Rails::Configuration for more options.

CASClient::Frameworks::Rails::Filter.configure(
    :cas_base_url => "https://cas.example.foo/"
  )

  # Skip frameworks you're not going to use (only works if using vendor/rails).
  # To use Rails without a database, you must remove the Active Record framework
  # config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

  # Only load the plugins named here, in the order given. By default, all plugins 
  # in vendor/plugins are loaded in alphabetical order.
  # :all can be used as a placeholder for all plugins not explicitly named
  # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

  # Add additional load paths for your own custom dirs
  # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Force all environments to use the same logger level
  # (by default production uses :info, the others :debug)
  # config.log_level = :debug

  # Your secret key for verifying cookie session data integrity.
  # If you change this key, all old sessions will become invalid!
  # Make sure the secret is at least 30 characters and all random, 
  # no regular words or you'll be exposed to dictionary attacks.
  config.action_controller.session = {
    :session_key => '_HelloProjects_session',
    :secret      
=> 
'b96668e0b0bc1db4d515650600d0dfadf284cb111477add9ff61b79c5dae007c664f444576b16f4
06
5b2d3b7ee0fc0bae0d2723c60834b681a157ce42312f4b5'
  }

  # Use the database for sessions instead of the cookie-based default,
  # which shouldn't be used to store highly confidential information
  # (create the session table with 'rake db:sessions:create')
  # config.action_controller.session_store = :active_record_store

  # Use SQL instead of Active Record's schema dumper when creating the test database.
  # This is necessary if your schema can't be completely dumped by the schema dumper,
  # like if you have constraints or database-specific column types
  # config.active_record.schema_format = :sql

  # Activate observers that should always be running
  # config.active_record.observers = :cacher, :garbage_collector

  # Make Active Record use UTC-base instead of local time
  # config.active_record.default_timezone = :utc
end
======================================
app/test_controller.rb

class TestController < ApplicationController
before_filter CASClient::Frameworks::Rails::Filter
end

any help is greatly appreciated.

Ahh! Put your CASClient configuration AFTER the Rails::Initializer stuff -- 
i.e. at
the very bottom of your environment.rb file.

The Rails Initializer is for configuring only Rails itself. You should never 
put code
in there that concerns third-party libraries like RubyCAS.

I think once you do this you should find that it works fine.

Excellent. I have it working now. Thank you very much for your support. :)
