    text
    copied!<p>Following Hartl's RailTutorial for Rails(3.2). I keep getting this error message or oddly a "The connection was reset" message:</p> <pre><code>ActiveRecord::RecordNotFound in UsersController#show Couldn't find User without an ID </code></pre> <p>I'm trying to log in and after successfully logging in, I want the application to redirect the user to user/show.html.erb. I believe that I'm passing the :id parameter in the show method in the users controller. Any tip/help would be appreciated!</p> <p>I've pasted some relevant files below. Let me know if you guys need anything else.</p> <p>sessions_controller.rb</p> <pre><code>class SessionsController &lt; ApplicationController def new @title = "Log in" end def create user = User.find_by_email(params[:session][:email]) if user.nil? flash.now[:error] = "Invalid email/password combination." @title = "Sign in" render 'new' else flash.now[:success] = "Successful login!" sign_in user redirect_to 'users/show' end end def destroy sign_out redirect_to root_path[:name] end end </code></pre> <p>users_controller.rb</p> <pre><code>class UsersController &lt; ApplicationController def new @user = User.new @title = "Sign up" end def show if params[:id].nil? &amp;&amp; current_user @user = current_user else @user = User.find(params[:id]) end @title = @user.name end def create @user = User.new(params[:user]) if @user.save sign_in @user flash[:success] = "Account created!" redirect_to @user else @title = "Sign up" render 'new' end end def destroy @user.destroy redirect_to users_path, :flash =&gt; { :success =&gt; "User destroyed." } end end </code></pre> <p>routes.rb</p> <pre><code>SampleApp::Application.routes.draw do resources :users resources :sessions, :only =&gt; [:new, :create, :destroy] match '/sessions', :to =&gt; 'users#show' match '/signup', :to =&gt; 'users#new' match '/login', :to =&gt; 'sessions#new' match '/logout', :to =&gt; 'sessions#destroy' root :to =&gt; 'pages#home' </code></pre> <p>Edit: Added sessions_helper.rb</p> <pre><code>module SessionsHelper def sign_in(user) cookies.permanent.signed[:remember_token] = user.remember_token current_user = user end def signed_in? !current_user.nil? end def current_user=(user) @current_user = user end def current_user @current_user ||= user_from_remember_token end def sign_out cookies.delete(:remember_token) current_user = nil end private def user_from_remember_token remember_token = cookies[:remember_token] User.find_by_remember_token(remember_token) unless remember_token.nil? end end </code></pre>
