I think I have fixed this problem.

First,type $ bundle show devise_openid_authenticatable to see where the bundled gem is installed. e.g. /Users/YOURNAME/.bundle/ruby/1.8/gems/devise_openid_authenticatable-1.0.0.alpha2 cd in this directory and modify /lib/devise_openid_authenticatable/schema.rb from apply_schema :identity_url, String to apply_devise_schema :identity_url, String

That's OK!

Hi, I'm the author of devise_openid_authenticatable. This issue was caused by a change in API in Devise 1.1.0 stable. I've added code to check for this and choose the appropriate API to use. The fix is released in the new devise_openid_authenticatable 1.0.0.alpha3.

Sorry about the trouble!
