Hi List,

This code sets a SESSION key and value and then calls
SESSION.invalidate():

after invalidate()
Produces this output:

It seems that SESSION.invalidate() does not take immediate effect.
Seems like a developer could getinto trouble if the same script
*both* does
SESSION.invalidate()
SESSION.set('something','somevalue').
Because after the script runs 'something' goes away when invalidate()
finally
occurs.
And is the effect described above to be expected or do I have this
wrong?
Thanks,
David
Sune,
Thats great! Thanks.
My tests confirm this excerpt from Collectors/Zope/1594: 'The suggestion
... to use "context.session_data_manager.getSessionData()" to get the
session after the call to invalidate works - it gives me a new session
object, and all is well :)'

It's maybe not obvious, but implicit in the book is that the bindings described for Scripts (container, context, etc.) apply only to Scripts, and not for External Methods. With External Methods, if the first argument to the function is named "self", you can treat "self" as being equivalent to a python script's "context". The request can be acquired as self.REQUEST.

[Zope] script or external method ?
Hi all, i'm a new user of Zope; i'm studing it since two weeks and i think it's very interesting, 'cause has the same power of j2ee application server but it is much more easy to use! While i was developing my first Zope application i fell into this trouble: i would like to write a script that create a folder, put some file in it, and set some properties. The code i've writed imports date object from datetime package: this makes it doesn't work like a script (python), so i adapt code as an external method; but when i run the method Zope says that he can't find symbol 'container'... (mumble) Well, 2 are the questions: First, what i've to do to get service variable like like container, context, request, etc.. ? Which are differences between script and external method coding? i remember that the zope book indicates only imports. Ok, thank you for reading.. Valerio - Principiante? Fedora a mani basse.

The Zope Book (2.7 edition, online) definitely gives help
on python scripting -- retry please.
You find ZPT examples in the "examples" folder of
".../Products/PageTemplates". Import the "zpt_examples.zexp" into
Zope ("import/export").
Of course, no general ressource provides direct answers
to your very specific problems...

The best method would be to know the meta types of all
UserFolders you are using...
>It would be perfect something like: Object1.superValues('User Folder')
"superValues" allows also a sequence of meta types (rather than
a single one).

You have to walk from the object up to the Zope root by following the

'aq_parent' attribute giving you the parent object. There you can check
if there exists a user folder (check for acl_users).
Is there any kind of method to query for security list of users?

[Zope] Get all user folder instances
Hi
I'm try to know the complet list of users in a Zope point with this
structure:
root
acl_users (user folder)
Folder1
acl_users (Pluggable user folder)
Folder2
acl_users (Another user folder)
Object1
Object2
how could I retrive the list of user folders (in this case: /acl_users,
/Folder1/acl_users and /Folder1/Folder2/acl_users)
It would be perfect something like: Object1.superValues('User Folder')
But this only retrive User Folder's not Pluggable user folder's nor
Another user folder's
Is there any kind of method to query for security list of users?

Re: [Zope] Does anyone care whether we deprecate ZClasses?
Jim Fulton escribió: ZClasses are a feature that support through-the-web development. Many people have found them useful in the past, but they have some significant deficiencies, including: - They can't be managed with file-system tools, especially revision control systems like CVS and subversion. - They don't work well with Python development tools, like profilers and debugger. - They aren't being actively maintained. Most serious Zope developers stopped using them a long time ago and are frustrated that we still expend resources keeping them around. For example, the release of Zope 2.8 has been delayed by the requirement of getting ZClasses working with Zope 2.8. We could choose to deprecate ZClasses. If we deprecated them in Zope 2.8, they would still work in Zope 2.8 and Zope 2.9, but their support would be removed in Zope 2.10. Would anyone be upset if this happened?

Re: [Zope] Re: login page problem
I have been trying to think of ways of providing specific pointers, So,
assuming you have a custom login page and a custom python script that
processes that page:
In the Python script you could set a cookie for the District:
context.REQUEST.RESPONSE.setCookie('District', district)
where district is the name of the District field in the form. The
District parameter is then always available to your page templates and
scripts in the REQUEST object.
At the end of your login script you would typically redirect to some
specific page like this:
return context.REQUEST.RESPONSE.redirect('aURL')
in exUserFolder you don't have to do anything else - the login works by
magic, which is very confusing.
Now for the problems:
If the login is wrong the system will call /standard_error_message, so
you have to customise that to send the user back to the login form with
a Login failed message.
If the user bookmarks a protected page and tries to jump to it without
being logged in, the system will call the login sequence starting in
acl_users, so you have to customise that to call your own login page.
After the user has logged in, whenever you need to get the Username you
would typically use a python script like this:
from AccessControl import getSecurityManager
return getSecurityManager().getUser().getUserName()

Tried cookie crumbler and MysqlUserFolder and UserFolder also but they
all need to changed much and my requirements are diffrent.
I'm building a trial govt. site for stores management which was built
previously in ASP.
The login page takes the districtname , username and passwd .
according to the type of user different menus are displayed.
For this i need to have the districtname , username and passwd
carried on throughout the session.
my current requirement is to pass the session vars through the python
script which is the action of the login form.
I've gone through the zopebook but dint find much help there.
can u plz tell me where do i get to know about pythopn scripting done
in zope n ZPT examples.
i'm really sorry for my erronous language. please dont overlook theese
humble requests.

Apparently, you need some background reading...
Especially, you need to understand that HTTP is a stateless
protocol and *EACH* request must somehow perform its own
authentication. That's why usually login information is
(somehow) coded in a cookie.
You really should follow the advice to look at an existing
UserFolder (they are responsible for authentication).
You may need to adapt/extend an existing UserFolder.
