Question

I am using devise and create login with Facebook using omniauth, but having problem of lost the devise helper methods access like current_user and user_signed_in? methods are not working.

EDIT

AuthenticationController

def create
    omniauth = request.env["omniauth.auth"]    
    user = User.find_by_provider_and_uid(omniauth["provider"], omniauth["uid"]) ||       User.create_with_omniauth(omniauth)    
    session[:user_id] = user.id    
    redirect_to dashboard_path(user.id), :notice => "Signed in!"    
end  

redirect_to USercontroller dashboard method

UserController

before_filter  :logged_in

 def dashboard    
    @user = User.find(params[:id])   
    @comment = Comment.new    
    @comments = @user.comments.all.paginate(:page => params[:page], :per_page => 5)    
 end 

so here control should go to dashboard method after checking logged_in method in ApplicationController

logged_in method in ApplicationController

Application Controller

def logged_in    
    if user_signed_in?     
       return true    
    else    
       redirect_to root_path    
       flash[:message] = "please login"    
    end     
  end 

when I logged in using facebook following code generated at console

Started GET "/users/52/dashboard" for 127.0.0.1 at Thu Mar 29 12:51:55 +0530 2012     
Processing by UsersController#dashboard as HTML     
  Parameters: {"id"=>"52"}     
Redirected to http://localhost:3000/     
Filter chain halted as :logged_in rendered or redirected     
Completed 302 Found in 2ms (ActiveRecord: 0.0ms)     

in the above code control is render from logged_in method to root_path but it shold render dashboard_path

So I am guessing User_signed_in? helper is not working I also use current_user in stead of that generate same error

As I see, user_signed_in? is working, but returns false, as for Devise user is not logged in. To fix this, just replace the session id storing with Devise sign_in method in your controller action:

def create
    omniauth = request.env["omniauth.auth"]    
    user = User.find_by_provider_and_uid(omniauth["provider"], omniauth["uid"]) ||       User.create_with_omniauth(omniauth)    
    sign_in(:user, user)

    # actually if you really really need that id in the session, you can leave this line too :)
    session[:user_id] = user.id 

    redirect_to dashboard_path(user.id), :notice => "Signed in!"    
end
