Redirecting without Plugins

I want to be redirected to the current page, after having logged in. I searched google and only saw ways to do this using certain plugins like devise.

Isn't there a simple Way to implement this path?

I start out with

  def store_location     session[:return_to] = request.fullpath   end

and I think the only thing left is passing this path to my redirect_ to code Line in the Sessions Controller, but "redirect_to store_location" won't work.

If only Plugins will help, can I use Devise without deleting or recreating my current User Model?

This isn't doing what you think. You may want to set up something more akin to accessors:

def store_location=(location)   session[:return_to] = location end

def store_location   session[:return_to] end

Then call the first method when you want to save the return page, and the second when you want to retrieve it.

Thanks. But I think the application still needs something more.

I defined those methods in my application_controller and added to my "requuire login Method"

  def require_login     unless user_signed_in?       redirect_to store_location=(request.fullpath)       redirect_to login_path,         alert: "Erst anmelden bitte!"     end   end

and added to my create method in the sessionscontroller:

  def create     user = User.find_by_username(params[:username])     if user && user.authenticate(params[:password])       session[:user_id] = user.id       #redirect_to startscreen_path,       redirect_to store_location,                   notice: "logged in"

When I now want to retrieve a page, that has the befor_filter "require login" I get the Error Message.

AbstractController::DoubleRenderError in GamesController#new

Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".

When logging in directly (without filters), I get the Error Message ActionController::ActionControllerError in SessionsController#create

Cannot redirect to nil!
