Specifics of using gem with bundler

[glebe]

When including gem through bundler, one should use the following syntax:

gem "ruby-openid", :require => 'openid'

to avoid problems like this on application start

ActionDispatch::Session::SessionRestoreError (Session contains objects whose class definition isn't available.
Remember to require the classes for all objects kept in the session.
(Original exception: uninitialized constant OpenID [NameError])
):

I have a similar problem, after restarting server.
