Hi there, I am trying to use the OpenID authentication plugin of DHH in conjuction with ruby-openid 2.1.2 gem put it seems there is a problem because in my login action the plugin redirects me to the openid provider and then i have the exception when i have to render or redirect to another page The exception is: ActionController::DoubleRenderError (Can only render or redirect once per action): Have you even encountered smth like that ? Thank you PS my session starts successfully the problem is that it does not refresh the page or redirect somewhere so i have to do it manually to see tha i am logged in

You might want to take a look at the OpenID Rails Kit ( http://railskits.com/openid/), which gives you a Rails sample app with the openid plugin integrated with the restful_authentication plugin so you can have both types of logins, ready to go. -- Benjamin Curtis http://railskits.com/ - Ready-made Rails code http://catchthebest.com/ - Team-powered recruiting http://www.bencurtis.com/ - Personal blog

I second Ben, check out a working demonstration application and see what you are doing different. It sounds like you may be doing some rendering outside of the authenticate_with_open_id block, but its hard to say without seeing your code.

Ok guys i ll give a second look, the strange thing is tha my current setup works but i am rewriting to port it Rails 2.x.x but somethings goes fundamendally wrong. So far the problem is that OpenID redirects as it should do but then i cannot redirect back to index and say hello user

What I have in my log is: OpenIdAuthentication::Association Load (0.000810) SELECT * FROM `open_id_authentication_associations` WHERE (`open_id_authentication_associations`.`server_url` = 'http:// www.myopenid.com/server') Redirected to http://www.myopenid.com/server?openid.assoc_handle... and then ActionController::DoubleRenderError (Can only render or redirect once per action): /Library/Ruby/Gems/1.8/gems/actionpack-2.1.2/lib/action_controller/ base.rb:842:in `render_with_no_layout' It fails only when openid url is correct, quite strange

Just in case anyone stumbs on this thread again: You should go exactly what the sample code does and that is why the plugin is looking for a identity_url or openid_url param So in your form there should be a an input with name anything like user [identity_url] wont do!
