Well, that's not really enough to go on. Take a look at the restful_authentication plugin or follow along with Agile Web Development with Rails for that kind of thing.

thanx ROB for u r advice...........

but still i dnt knw how 2 use........if u hav any code for lgoin method thn pls paste it here.........i m getting prbolm of .......... NoMethodError

my method is........... ------------------------------------------------------------------------- def login_submit   if session['user']      @logged_in = true    else      @logged_in = false    end        @user = User.new(@params['user'])    if @session['user'] = User.authenticate(@params['user']['username'], @params['user']['password'])      flash[:notice] = l(:user_login_succeeded)

Where is the l method defined? Is that where your NoMethodError comes from?

Also, don't user the @session or @params variables, use the session and params methods instead:

   if session['user'] = User.authenticate(params['user']['username'],                                           params['user']['password'])

-Rob

     redirect_to :action => 'welcome'    else      @login = @params['user']['login']      flash.now[:notice] = l(:user_login_failed)    end end -------------------------------------------------------------------------- and in the rhtml file the form is..........

<% form_tag :controller => "user", :action => "login_submit" do %> <p class="input_fields"><label>Username: &nbsp;</label><input id="user_username" name="user[username]" size="15" type="text" /></p> <p class="input_fields"><label>Password: &nbsp;</label><input id="user_password" name="user[password]" size="15" type="password" /></p><br clear="all" />

<%= submit_tag "Login"%> <% end %> -------------------------------------------------------------------------- so can you help mee what is this prblm .............
