Routing Error No route matches [POST] "/sessions/new"

I am having an error and hoping somebody could help and give me some clues what to do with this. I am following Agile development book in a way selectively and while I copied their code, the result is as follow:

Routing Error
No route matches [POST] "/sessions/new"
Try running rake routes for more information on available routes.

This is what I have in my routes.rb file:

get 'admin' => 'admin#index'
controller :sessions do
 get 'login' => :new
 post 'login' => :create
 delete 'logout' => :destroy
end
resources :users

In my session_controller: skip_before_filter :authorize def new end

def create
 user = User.find_by_name(params[:login_name])
 if user and user.authenticate(params[:password])
  session[:user_id] = user.id
  redirect_to admin_url
 else
  redirect_to login_url, alert: "Invalid user/password combination"
 end
end

def destroy
 session[:user_id] = nil
 redirect_to users_url, notice: "Logged out"
end

In my session#new.html.erb :

  <% if flash[:alert] %>
  <p id="notice"><%= flash[:alert] %></p>
 <% end %>
 <%= form_tag do %>
  <fieldset>
    <legend>Please Log In</legend>
    <div>
      <%= label_tag :login_name, 'Login name:' %>
      <%= text_field_tag :login_name, params[:login_name] %>
    </div>
    <div>
      <%= label_tag :password, 'Password:' %>
      <%= password_field_tag :password, params[:password] %>
    </div>
    <div>
      <%= submit_tag "Login" %>
    </div>
  </fieldset>
<% end %>

Also I am using has_secure_password and have recently updated to Ruby v 193 and Rails 3.2.8. I am only still learning ROR and therefore will appreciate your help a lot- I have been trying to figure it out myself but I was not able to.

What do you get when running 'rake routes'? Could you copy that? Also, could you copy the HTML code rendered by the browser of your form?

You're currently posting to the same page which the form is on. Since your view is the new action in the sessions controller, it is submitting a POST to sessions/new. Rails is then looking for a POST route to sessions#new. Since none exists, it's erroring.

However if you look at your routes, you can see you have a post 'login' => :create route which actually goes to the create action you set up to handle the form submission. Therefore if you submit the form to /login the route will nicely POST everything through to the intended action.

To do this, change:

<%= form_tag do %>

to

<%= form_tag('/login') do %>

Also, I strongly recommend you read this: http://guides.rubyonrails.org/routing.html which will give you a better overview of how rails routing works.

EDIT: I've just seen you're probably resubmitting to /login which then should work... I think it will still default to submitting to the current action however which is officially sessions/new so can you give my suggestion a go and see if it makes a difference?
