Re: Who is logged in??

Hi Jonathan
I've gotten it back working as before
Here's what i did
As i say i using an class called sec_auth
that i have since the pre-spyce days of cgi and cookies (it has the  
salt and the encryption method etc. for each project)
the login method performs the select on  the user attributes table
select * from user_attributes where
  user_name=login and password=password
this puts results in in the dictionary called auth

My config.py file looks likes
----
#my_auth is an instance of the sec_auth
udata=None

def validator(login,password):
   global udata
   try:
      udata  = myauth.login(login,password)
   except sec_auth.BadUserName,sec_auth.BadCredentialsError:
      udata=None
   if udata:
      return login
   else:
     return None
--------------
in parent.spi i have
--
[[.import name=session]]
<f:form>
<spy:login />
[[\
   from spyceConfig import udata
   if not session.get('udata') and udata:
         session['udata'] = udata

]]
<div id="banner">
  You are logged in to SMW as [[=session['udata']['name'] ]]
  <spy:logout>
</div>

</form>
------
I realize that i have to put the udata in the session since if the  
server restarts and i am logged in already then udata is none

The advantage of the login_tags is that think i can easily implement  
functionality like
who's on line,user active count etc.
since i can store the session_id and the associated id in my sessions  
table

One potential problem?
If i logout of one site do i logout of all sites (cookie.delete 
(__spy_login'))??
Regards
Chris
