  1. POCreate Session in Rails 3.1 Hartl Tutorial
    text
    copied!<p>This question is admittedly long. So I appreciate any support from the rubytutorial community. I am in Chapter 9, attempting to create a session for a logged-in user. </p> <p>I've done the tutorial already in &lt; Rails 3.1. Since I am now using Rails 3.1, I headed on over to Chapter 13 and linked to the (very good) <a href="http://railscasts.com/episodes/270-authentication-in-rails-3-1" rel="nofollow">Railscasts (#270) on the subject</a>. I was able to rewrite my user sign up pretty easily thanks to has_secure_password. </p> <p>When I try to log in with a user in the database I see this in the console):</p> <pre><code>No route matches {:action=&gt;"show", :controller=&gt;"users"} </code></pre> <p>Seems like I need to create a route and it should work. But if that is the case, why can I go 'users/1' and the view appear? I am using the route user_path(@user), @user in my sessions and users controllers (below).</p> <p>Here is what I did.</p> <p>Pass a form to the Session controller new action (note: I use form_tag and not form_for)</p> <pre><code> &lt;%= form_tag sessions_path do %&gt; &lt;div class="field"&gt; &lt;%= label_tag :email %&gt;&lt;br /&gt; &lt;%= text_field_tag :email, params[:email] %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= label_tag :password %&gt;&lt;br /&gt; &lt;%= password_field_tag :password %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= submit_tag "Sign In" %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>Then, create action in sessions_controller.rb</p> <pre><code>def create #Assign object by email attribute user = User.find_by_email(params[:email]) # User is present and has access, must be true otherwise nil object if user &amp;&amp; user.authenticate(params[:password]) session[:user_id] = user.id RIGHT HERE IS THE PROBLEM redirect_to user_path(@user), :notice =&gt; "Logged in!" else #Use flash.now on render not flash[] flash.now.alert = "Invalid email or password" render "new" end end </code></pre> <p>And finally Create action for users_controller.rb, which works fine.</p> <pre><code>def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome to the Sample App!" redirect_to @user else render "new" @user.password.clear @user.password_confirmation.clear end end </code></pre> <p>Leaving my User model:</p> <pre><code>attr_accessible :name, :email, :password, :password_confirmation email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i has_secure_password </code></pre> <p>Oh and here is my current routes.rb file</p> <pre><code> resources :users resources :sessions, only: [:create, :new, :destroy] root to: "pages#home" match "/about", to: "pages#about" match "/contact", to: "pages#contact" match "/help", to: "pages#help" match "/signup", to: "users#new" match "/signin", to: "sessions#new" match "/signout", to: "sessions#destroy" </code></pre> <p>And finally my output when I run rake routes:</p> <pre><code>users GET /users(.:format) {:action=&gt;"index", :controller=&gt;"users"} POST /users(.:format) {:action=&gt;"create", :controller=&gt;"users"} new_user GET /users/new(.:format) {:action=&gt;"new", :controller=&gt;"users"} edit_user GET /users/:id/edit(.:format) {:action=&gt;"edit", :controller=&gt;"users"} user GET /users/:id(.:format) {:action=&gt;"show", :controller=&gt;"users"} PUT /users/:id(.:format) {:action=&gt;"update", :controller=&gt;"users"} DELETE /users/:id(.:format) {:action=&gt;"destroy", :controller=&gt;"users"} sessions POST /sessions(.:format) {:action=&gt;"create", :controller=&gt;"sessions"} new_session GET /sessions/new(.:format) {:action=&gt;"new", :controller=&gt;"sessions"} session DELETE /sessions/:id(.:format) {:action=&gt;"destroy", :controller=&gt;"sessions"} root / {:controller=&gt;"pages", :action=&gt;"home"} about /about(.:format) {:controller=&gt;"pages", :action=&gt;"about"} contact /contact(.:format) {:controller=&gt;"pages", :action=&gt;"contact"} help /help(.:format) {:controller=&gt;"pages", :action=&gt;"help"} signup /signup(.:format) {:controller=&gt;"users", :action=&gt;"new"} signin /signin(.:format) {:controller=&gt;"sessions", :action=&gt;"new"} signout /signout(.:format) {:controller=&gt;"sessions", :action=&gt;"destroy"} </code></pre>
