Why are parameter values getting lost?

Rails
1

Hi,

I have this login form (app/views/register/start.rhtml):

<% form_tag ‘session/new’ do -%>

Login
<%= text_field_tag 'login' %>

Password
<%= password_field_tag 'password' %>

<%= submit_tag 'Log in' %>

<% end -%>

But it seems when my form is getting processed by my app/controllers/
session_controller.rb controller, the value of the login parameter is
NULL. Here’s the controller code and the entry from the log file:

===============controller code================================
def create
self.current_user = User.authenticate(params[:login],
params[:password])
if logged_in?
if params[:remember_me] == “1”
self.current_user.remember_me
cookies[:auth_token] = { :value =>
self.current_user.remember_token , :expires =>
self.current_user.remember_token_expires_at }
end
# The next two lines were added 1/24/08
@user = User.find(:first, :conditions => [“login = ?”,
params[:login]])
session[:user_id] = @user.id
flash[:notice] = “Logged in successfully”
redirect_to :controller => ‘order’, :action => ‘start’
else
flash[:error] = “Authentication failed.”
redirect_to :controller => ‘register’, :action => ‘start’
end
end
================end controller code============================

i’m pretty sure it’s to do with the bit when you redirect to ‘create’

i’m not sure why you’re doing it like that but to keep hold of the
params i think you need to put them in local(?) variables…when you
receive them in new you need to say, for example, @login =
params[:login], @password = params[:password], then I THINK you’ll be
able to see these variables in your create action
