can anyone give me a simple example of using tools.session_auth with cp3

[Hal]

I have tried to update my working cp2 code and failed.
Here is a simplified version of my working cp2 code:

#### start
import cherrypy

def loadUserByUsername(login):
ulist=[("user1","pass1"),("user2","pass2")]
for u,p in ulist:
if u==login:
return (u,p)

def checkLoginAndPassword(login, password):
user = loadUserByUsername(login)
if user==None:
return u'Wrong login/password'

settings={ 'global':{
'session_authenticate_filter.on': True,
'session_filter.on':True,
},
'/': {
'session_authenticate_filter.check_login_and_password':
checkLoginAndPassword,
'session_authenticate_filter.load_user_by_username':
loadUserByUsername,
},
}
cherrypy.config.update(settings)

class Root:
@cherrypy.expose
def index(self):
return " Hello, you passed auth"

cherrypy.root=Root()
cherrypy.server.start()

### end
and a not working version of the cp3 code

### start
import cherrypy

def loadUserByUsername(login):
ulist=[("user1","pass1"),("user2","pass2")]
for u,p in ulist:
if u==login:
return (u,p)

def checkLoginAndPassword(login, password):
user = loadUserByUsername(login)
if user==None:
return u'Wrong login/password'

class Root:
_cp_config = {
'tools.session_auth': True,
'tools.sessions.on': True,
'tools.session_auth.check_username_and_password':
checkLoginAndPassword,
'tools.session_auth.on_check': loadUserByUsername,
}

@cherrypy.expose
def index(self):
return " Hello, you passed auth"

cherrypy.tree.mount(Root)
cherrypy.server.quickstart()
cherrypy.engine.start()
### end

[snip cp2 version]

[snip auth handlers]

Possible problem #1: maybe it should be tools.session_auth.on = True?

Possible problem #2: It should probably be
cherrypy.tree.mount(Root()), or you could do
cherrypy.quickstart(Root()).

HTH,

Yes right on both counts, it works 10x

I read your thread and tried to get this working on CP 3.0 using
this code:

------
import cherrypy

def loadUserByUsername(login):
ulist=[("user1","pass1"),("user2","pass2")]
for u,p in ulist:
if u==login:
return (u,p)

def checkLoginAndPassword(login, password):
user = loadUserByUsername(login)
if user==None:
return u'Wrong login/password'

class Root:
_cp_config = {
'tools.session_auth.on': True,
'tools.session_auth.check_username_and_password': checkLoginAndPassword,
'tools.session_auth.on_check': loadUserByUsername,
}

@cherrypy.expose

def index(self):
return " Hello, you passed auth"

cherrypy.tree.mount(Root())
cherrypy.server.quickstart()
cherrypy.engine.start()
------

However, in my case, it throws the error:

[30/Jan/2007:11:38:30] HTTP Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/cherrypy/_cprequest.py", line 340, in respond

File "/usr/lib/python2.4/site-packages/cherrypy/lib/cptools.py", line 246, in do_check
sess = cherrypy.session
AttributeError: 'module' object has no attribute 'session'

Any idea what I'm missing?

Thanks

Because sessions are an extension to CherryPy (and not a builtin), there
will be no "cehrrypy.session" object unless you either 1) turn on
tools.sessions, or 2) do it yourself by calling lib.sessions.init and
friends.

Thanks. That did the trick. For those like me who have struggled with some of
these things, below you will find a working code example for CP 3.0:

-----
import cherrypy

def loadUserByUsername(login):
ulist=[("user1","pass1"),("user2","pass2")]
for u,p in ulist:
if u==login:
return (u,p)

def checkLoginAndPassword(login, password):
user = loadUserByUsername(login)
if user==None:
return u'Wrong login/password'

class Root:
_cp_config = {
'tools.sessions.on': True,

'tools.session_auth.on': True,
'tools.session_auth.check_username_and_password': checkLoginAndPassword,
'tools.session_auth.on_check': loadUserByUsername,
}

@cherrypy.expose
def index(self):
return " Hello, you passed auth"

cherrypy.tree.mount(Root())
cherrypy.server.quickstart()
cherrypy.engine.start()
