my OS is ubuntu7.10:
1.cd to the project directory
2.
sudo gem install ruby-openid
3.
sudo ruby script/plugin install open_id_authentication
4.rake -T open_id (to see the rake command)
5.
rake open_id_authentication:db:create
6.in the open-id migrate add these lines:
add_column :users, :identity_url, :string
(in self.up)
remove_column :users, :identity_url
(in self.down)
7.run the migrate
8.add a line in routes.rb:
map.open_id_complete 'session', :controller => "session", :action => "create",:requirements => { :method => :get }
VERY VERY IMPORTENT!!!
make sure the map.open_id_complete line above the map.resource :session line;(IT waste lots of my time!!!)
9:add a :identity_url in user.rb and it will look like:
attr_accessible :login, :email, :password, :password_confirmation, :identity_url
10.add some line in session/new.rhtml:
<p>
<label for="openid_url">OpenID URL</label><br/>
<%=text_field_tag "openid_url"%>
</p>
11.:
# This controller handles the login/logout function of the site.
class SessionController < ApplicationController
# Be sure to include AuthenticationSystem in Application Controller instead
# include AuthenticatedSystem
# render new.rhtml
layout "welcome"
def new
end
def create
if using_open_id?

end
12.add some css:
/* embeds the openid image in the text field */
input#openid_url {
background: url(http://openid.net/login-bg.gif) no-repeat;
background-color: #fff;
background-position: 0 50%;
color: #000;
padding-left: 18px;
}
