undefined method prepare!' for class ActionDispatch::Session::AbstractStore'

[restebanez]

Hi there,

devise_cas_authenticatable seems not to work in rails 3.1.1 and ruby 1.9.2-p290. After bundle install, i run:

rails generate devise User, and i got this error:

Hi Rodrigo, thanks for the bug report! We're actually aware of the issue and there's a potential fix checked into master, but we're still testing to make sure we haven't broken single sign-out support.

If you like, please try changing to use the master branch from git in your Gemfile:

gem 'devise_cas_authenticatable', :git => 'git://github.com/nbudin/devise_cas_authenticatable.git'

If that doesn't work for you, please let me know!

how's the fix coming along?

[restebanez]

The bug went away using the git repository. Thanks a lot!

[nbudin]

At this point I'm satisfied that this fixes Rails 3.1. The only question is whether this change breaks single sign-out support, which jeremyhaile coded. I don't have a CAS server with single sign-out to test it with, so I'll either have to set one up or write a unit test to simulate one. If anyone has a SSO-enabled CAS server and would like to give it a try, that would probably speed the release.

[restebanez]

In a month or so i'll returned to the CAS authentication, after i saw that the bug went away, i had to change to a different project. I'll report to you as soon as CAS is configured and working

Hi all,

When I followed nbudin's instructions to fix this issue I encountered this error upon executing bundler:

Using devise_cas_authenticatable (1.0.0.alpha12) from git://github.com/nbudin/devise_cas_authenticatable.git (at master) 
NoMethodError: undefined method `write' for #<Syck::Emitter:0x007f9fef20a558>
An error occured while installing devise_cas_authenticatable (1.0.0.alpha12), and Bundler cannot continue.
Make sure that `gem install devise_cas_authenticatable -v '1.0.0.alpha12'` succeeds before bundling.

The gem install command succeeds however:

gem install devise_cas_authenticatable -v '1.0.0.alpha12'
Successfully installed devise_cas_authenticatable-1.0.0.alpha12
1 gem installed
Installing ri documentation for devise_cas_authenticatable-1.0.0.alpha12...
Installing RDoc documentation for devise_cas_authenticatable-1.0.0.alpha12...

Is this related to the above issue?

EDIT: Turns out I just needed to update the bundler gem, d'oh!

gem install bundler

i switched to :git version and it was solved as well. but i don't have a SSO to help, sorry
