Registration in Rails - authentication

Question

I am attempting to create a new user in rails. There is a username, email, password and password confirm field on the new user form. When I click on the create user button on the web page, the new_user form simply refreshes and the user is not added to the database.
Here is the code for my register method in the authentication controller
def register
#user = User.new(params[:user])
if #user.valid?
#user.save
session[:user_id] = #user.id
flash[:notice] = 'Welcome.'
redirect_to sign_in_url
else
render :action => "new_user"
end
end
This is my new_user form:
<p>Sign Up</p>
<%= form_for #user, :as => :user, :url => new_user_path, :method => :put do |f| %>
<p>
<%= f.label 'username:' %><br/>
<%= f.text_field :username %>
<%= show_field_error(#user, :username) %>
</p>
<p>
<%= f.label 'email:' %><br/>
<%= f.text_field :email %>
<%= show_field_error(#user, :email) %>
</p>
<p>
<%= f.label 'password:' %><br/>
<%= f.password_field :password %>
<%= show_field_error(#user, :password) %>
</p>
<p>
<%= f.label 'password confirmation:' %><br/>
<%= f.password_field :password_confirmation %>
<%= show_field_error(#user, :password_confirmation) %>
</p>
<p>
<%= f.submit 'Sign Up' %>
<%= f.submit 'Clear Form', :type => 'reset' %>
</p>
Can anybody point me in the right direction?

Your call to new_user_path in your form references the url to User#new if you have defined resources :users in your routes.rb file. You will need to replace new_user_path with register_user_path, if you have defined register in your routes file. Double check for the path with by running rake routes, though.
From what I can see, there is no need to use have the register action. It'd make more sense to use RESTful actions new, create, index, show, edit, update, and destroy in your case, since your logic follows the intuition behind them. Rails makes this convention easy to follow. See the routing Rails guide here for more.
