after successful verification from LinkedIn i forward to this controller and i get the
uninitialized constant UsersController::LinkedIn
this is where the control goes once the authentication is successful.
class UsersController < ApplicationController
def index
# get your api keys at https://www.linkedin.com/secure/developer
client = LinkedIn::Client.new("ddddd", "eeeee")
request_token = client.request_token(:oauth_callback =>"http://localhost:3000/users/callback")
session[:rtoken] = request_token.token
session[:rsecret] = request_token.secret
redirect_to client.request_token.authorize_url
end
def callback
client = LinkedIn::Client.new("dddd", "eeeeee")
if session[:atoken].nil?
pin = params[:oauth_verifier]
atoken, asecret = client.authorize_from_request(session[:rtoken], session[:rsecret], pin)
session[:atoken] = atoken
session[:asecret] = asecret
else
client.authorize_from_access(session[:atoken], session[:asecret])
end
@profile = client.profile
@connections = client.connections
end
end

Please help me to solve this as i am new guy to ror.
UPDATED answer for your sessions_controller question:
you have to use 'session' inside the 'actions', e.g. your current code:
class SessionsController < ApplicationController
def create
# ... some code for create action
end
# NOTICE: these 4 lines of code should be placed in an "action"
#user = User.find_by_provider_and_uid(auth["pr
session[:user_id] = profile.name
redirect_to root_url, :notice => "Signed in!"
#end
def destroy
# ... some code for destroy action
end
end
you should move the 4 lines of code into an action, so that Rails could recorgnize "session":
class SessionsController < ApplicationController
def create
# ... some code for create action
session[:user_id] = profile.name
redirect_to root_url, :notice => "Signed in!"
end
=============
ANSWER for the previous question:
if you are using Rails3, you have to add every rubygems to the Gemfile, e.g:
gem "rake", "0.8.7"
gem 'rails', '3.0.5'
gem 'linkedin'
here , by adding gem 'linkedin', the ruby code has the ability to include all the stuff comes from 'linkedin' gem.
DEPRECATED Rails 2.x WAY: if you don't do this, you have to add the require statement in your controller, e.g.
# don't do this if you are using Gemfile
require 'linkedin'
class UsersController < ApplicationController
def index
# ...
end
