In ruby we can make a line comments by using #.
but when we use the same ruby code in .rhtml, how can i make comments a
line

<%= link_to 'Create New Book', :controller => 'Book', :action => 'list'
%>

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.

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 %>
--------------------------------------------------------------------------
