Subject: Login does not work

Hi, could anybody help me try to get a login function working, I have
created a database for users called user1, I have the login screen set
up but when i hit login with a correct username and password, nothing
happens

I am expecting the lgin button to direct the user to the main page and
show the user as logged on, but nothing happens! Thanks!


Controller

class User1Controller < ApplicationController
  def index
    @title = "Temporary View"
    @users = User1.find(:all)
  end

def register
    @title = "Register"

    if request.post?
      @user = User1.new(params[:user1])
      if @user.save
        session[:user_id] = @user.id
        flash[:notice] = "User with login #{@user.screen_name} created!"
        redirect_to :action => :index
      end
    end
  end




end


  def login
    @title = "Title"

    if request.post?
      @user = User1.new(params[:user1])
      user = User.find_by_screen_name_and_password(@user.screen_name,
@user.password)
      if user
        session[:user_id] = user.id
        flash[:notice] = "User #{user.screen_name} logged in"
        redirect_to :action => "index"
      else
        # Don't show the password in the view
        @user.password = nil
        flash[:notice] = "Invalid email/password combination"
      end


      end
    end

def logout
    session[:user_id] = nil
    flash[:notice] = "Logged out"
    redirect_to :controller => :site, :action => :index
  end


  end





Login View


<h1>Login</h1>
<%= error_messages_for :user %>
<% form_for :user do |f| %>
  <p>
    <%= f.label :screen_name %>:
    <%= f.text_field :screen_name %>
  </p>
  <p>
    <%= f.label :password %>:
    <%= f.password_field :password  %>
  </p>
  <p>
    <%= f.submit "Login" %>
  </p>
<p>
  Not a member? <%= link_to "Register now!", :action => "register" %>
</p>

<% end %>
