I just finished a RPXNow Rails plugin and gem
so that everyone can enjoy the great usability + simplicity of RPX
Use OpenId / Google / Yahoo / MySpace / Facebook connect transparently through the same interface.
Usage
#login.erb
RPXNow.embed_code('mywebsite',url_for(:controller=>:session, :action=>:rpx_token))
#sessions_controller.rb
def rpx_token
data = RPXNow.user_data(params[:token],'YOUR RPX API KEY')
self.current_user = User.find_by_identifier(data[:identifier]) || User.create!(data)
redirect_to '/'
end
Doing the same with OpenId is impossible, since every provider has his own standards of which fields to supply and how to name them.
Happy login!

Do you have any tips on how to get RPX to work with a WordPress blog?

would be interesting to use rpx as plugin for wordpress, but i have not seen such a thing…
aybe a good start woulkd be to simply port the RPXNow library to php, and start with this.

Typo on this line, should read RPXNow
data = RPXNew.user_data(params[:token],’YOUR RPX API KEY’)

Thanks for this great plugin. I’m getting an, undefined method `find_by_identifier’. Where is this method defined or have I missed something?

you need an identifier(string) column on your model -> find_by_identifier works, I just added an example migration to make that easier
(identifier is used to store the unique identifier every provider assigns to its users)

Will this work with rails 2.1?

It works with anything, sinatra/waves/merb/rails 1.2.6 / 2.1 / 2.3.3, is basically only a gem also available as rails plugin, so there should be no problems.

data not found == identifier was wrong / already has been used, make sure to pass the correct identifier, and to not pass it e.g. twice

Hi Michael,
Thanks for the great information.
I have a very newbie question:
RPXNow.embed_code(‘mywebsite’,rpx_token_sessions_url)
what is “rpx_token_sessions_url” how do i construct it?
I have registered an application called mosaicit at RPX website.
and am trying to connect from localhost then how should my url look like ?
Thanks,
Pratik

I only got this error when logging in twice with the same identifier, e.g. using refresh page, or when the identifier was wrong or when the identifier was very old
