Subject: [Zope] LoginManager and ZPatterns - Sparse Install Docs, Help.
Date: Sat, 5 Aug 2000 16:00:29 -0400
charset="iso-8859-1"
Zopistas,
Maybe I'm making this harder than it needs to be.
I want to set up a membership system for the site I am developing with Zope.
I do not want to "restrict" any part of the site - instead I want a user to
login (at their convenience) and then extend the "menu" options based on
their group membership. If a user is not logged in - no problem, they just
won't be able to view the advanced options - they'll still be able to surf
the site (I want to maintain my user list in an external database as well).
What is the best tool in Zope to accomplish this? After searching the site,
I find there are several products - ACL Users, GUF, and LoginManager. Is GUF
deprecated (The intro tends to give me this feeling)? Is LoginManager the
way to go?
It also appears GUF is more tailored toward restrictive authentication (I've
already perused the "Using GUF with an SQL Database" how-to). I want a user
to login (via HTML form/cookie) whenever they like, and get presented with
additional menu options (based on their AUTHENICATED/GROUP status). Not have
them try to access a "restricted" page (or type "manage") and get a basic
authentication login box to get in.
As far as LoginManager itself is concerned, I assume it requires ZPatterns.
However, the Zpatterns install instructions are *very sparse.* How do I get
the thing set up? Here's verbatim from the ZPatterns docs:
-----
After unpacking the ZPatterns product, you will need to build this [c]
>extension using the included Setup file in the ZPatterns directory.
-----
How do I use the "Setup" file?? With the command "python Setup"? It doesn't
say *how* to use it.
-----
Please follow the standard procedures for building a Python module on your
platform. (On Unix-ish systems, this usually consists of copying a
Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot
>followed by make.
-----
What are these standard procedures?? I built Python itself with
"configure|Make|Make install". Where do I get this "Makefile.pre.in" file in
the first place, from my Python src/build directory?? Correct me if I'm
wrong, but there's usually some kind of script file to run that get's things
going, or a "configure" script. I find none of this in the
lib/python/Products/ZPatterns directory after I untarred it.
So, I'm basically stumped. It doesn't appear GUF will do what I need, and I
have failed on multiple attempts to get Loginmanager/ZPatterns installed. If
someone could point me in the right direction on this I sure would
appreciate it.
Thanks much,
-Darin Lee

If I'm running current stable versions of Zope and Zope-MysqlDA, do I
need to consider threading issues or are these safely abstracted away
in the DA?
"Luis Cortes" <LCortes@IMEME.NET> writes:

I'm running the Debian frozen release, i.e. 2.1.6 with security
patches. Do you have any specific references on the thread problem? I
find nothing on it in the changelogs I've found. Do I need to go to
2.2.0 for this?
A seach on 'threading problem' turns up a hornet's nest of deep
technical shit. Most of those mails are a year old, is this still an
issue? As a developer, do I need to understand threading issues when
developing database accessing products, or may I safely assume that
threading, locking and transaction semantics are handled between the
Database Adapter and Zope itself?
I found a mail that says I should run Zope single-threaded when using
MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html
Checking my installation, I find I have no threading option activated,
which means I'll be running the default number of 4 threads. What will
my server performance look like if I reduce this to 1 thread? Not
that I'm having such a wonderful performance now, having my pager go
off every hour :-(
Is there a way to allocate different threads to different SiteRoot
virtual websites, so I can lock a single site in a single thread but
let my installation as a whole still retain some multi-threading
performance?

| Good evening.
|
| I know how to make a Python Class, which is a container. But how do
| I make another Class which can only be added from the container-class
| I have created. Know what I mean? The last class should only show up
| in the "Available Objects"-list if the user is in a instance of the
| first class. Did this make any sense?
|
| Thanks for any answers. :-)
This is easier than you might think:-
Step 1: Do not register your 'sub' class(es) in your __init__.py
Step 2: In your container class import your sub class manage_add function(s)
(not sure if this is really needed, but, I do it for completeness).
Step 3: In your container class add:-
meta_types=({'name':'Sub Product', 'action':'manage_addSubProduct'},) # Sub-ob
ject types that are specific to this object
You can add as many as you like...
Step 5: Optionally add a meta_type to your sub class (if you haven't)
Step 6: Optionally add icon='thisIcon.gif" into your sub classes so they get
pretty icons.
Copy over new Product, and Restart Zope :-)

Hello,
I installed zope 2.2.0-1 from the Debian (Woody) distribution. No
problems are reported during the installation but when I try to access
http://localhost:9673/ I get the following error:
Zope Error
Zope has encountered an error while publishing this
resource.
Error Type: TypeError
Error Value: unexpected keyword argument: validated_hook
The same happens when I try to access the management menus.
Is the Woody package broken? Any ideas?
Thank you,

It would seem to be broken.... you might want to contact the package

Did u upgrade an existing zope instance with the new distribution, or was
it a clean install? Did you install the SiteAccess product? This sounds
like the error you get with an old SiteAccess object in the new zope2.2.
You need to upgrade to the new SiteAccess.

Thank you for the hint.
I had purged my old zope (dpkg --purge) but it seems something was still
there hanging around. I did an "rm -rf /var/lib/zope /usr/lib/zope" and
reinstalled zope and it worked!
I then tried to install the package "zope-siteaccess" from Woody but it
depends on zope (>= 2.0.0-2) which is not available :|
I'm sort of new to zope so may I ask, Do I need this "zope-siteaccess"
package from Woody?
Thank you,

You only need the siteaccess product if you wish to server multiple domains
from one zope instance.

Precondition
Allows you to specify a precondition for the File. A precondition is a
method or document which is executed before the File is viewed or
downloaded. If the precondition raises an exception then the File cannot
be viewed.
This is from the Help page presented when you click the 'help' button on the
'Edit' tab of a 'File' object.

Date: Sun, 6 Aug 2000 12:52:30 +0200
charset="iso-8859-1"
I am experimenting with xml-rpc and Zope. Some Methods from the API work ok,
but others return an error. A common error is:
Error Value: cannot marshal <extension class
Acquisition.ImplicitAcquirerWrapper at 00C950F0> objects
I receive this error for example when for Zope 2.1.6 I execute:
ObjectManager.objectValues
Where as the next Method works ok:
ObjectManager.objectItems
Maybe the to be returned info is to complex ?

Subject: [Zope] Problem with proxy role...
Date: Sun, 6 Aug 2000 16:43:18 +0200
charset="iso-8859-1"
Hi!
I'm trying to set up a site with user registration (similar to that on the
zope site), and have been using the JobBoard HOWTO as an example
of how to let anonymous users add objects. The code works just like
it should when I'm logged in as Manager, and I *have* set the proxy
role of the method that processes the form to Manager, but still, when
I try to use it anonymously, I get the message that I don't have access
to the user class... I've tried several implementations, but I don't
understand
the problem...
If the method is proxied as Manager, shouldn't it (and all
the methods it calls) have the rights of Manager? (I also tried adding
Owner, but that didn't help...) In that case - why doesn't it work, while
it *does* work for me when I'm logged in as Manager?
Can there be a standard problem hiding here? (Or, perhaps, it's
obvious?)
Any help is appreciated. Thanks.

I knew I'd read it somewhere!
First I ran through the help menu, but I must have looked at
File/Image Add and missed File/Image Edit. Then I looked at an
Image (I had no File objects handy), and when I saw that the help
tab for the Edit, page had no description of precondition, and indeed
that there was no way to set it, I figured the docs for it must
only be in the API section. But the API section does not discuss
*any* of the call paramters. So I thought it was undocumented.
Since the code supports preconditions on an Image, is this an interface
error or a design decision (the latter seems more likely)? If it's
a design decision, shouldn't precondition still be documented in
the Image api help doc?
This is an example of a systematic problem with the (very useful
<grin>) help docs as they stand: if the API docs implicitly assume
that the parameters are documented in the corresponding management
interface panel then there should at least by a cross link; and if
there are sometimes parameters that are *not* documented on the
manage page, then that needs to be taken into account somehow.

Only strings, integers, floats, "booleans", dictionaries, tuples, lists,
and special "datetime", base64, and fault objects can be passed via
XML-RPC. Anything else is too complex. The spec at
http://www.xml-rpc.com/spec is useful.

Magnus:
In setting up the JobBoard from the HOWTO, what worked for me was setting
the proxy role for both the method in the JobBoard product that processes
the form to "Manager" (Product
at/Control_Panel/Products/JobBoard/job_board_entry_add); as well as the
regular method that processes the form to "Manager".
The HOWTO seems to indicate that only the regular method must be set to
proxy, i.e., "Important:The "entry_addProcessor" must be set to "Manager"
proxy for it to work." When I followed only this instruction, I ran into
the same problem that you did.
However, while this works for me, I am not sure that this is the zen way of
doing things.

Roger

Subject: [Zope] Sequence problem
Date: Sun, 6 Aug 2000 18:07:41 +0100
charset="iso-8859-1"
This little DTML code is supposed to be generic for alla folder is the profil folder.
What I want to do is a to have a next folder and previous folder in evey one.
/profil/
/folder_XHJSD
/folder_GIEHG
/folder_OWKD
/and_many_more
/....
/folders_here
document_html
Document_html is acquired in all folders in the profil folder.
I started doing something like this:
<dtml-in "profil.objectValues(['Folder'])" sort=id>
<dtml-var id>,
</dtml-in>
... and this returns: folder_XHJSD, folder_GIEHG, folder_OWKD....
What I want to do is something like this:
<dtml-call "REQUEST.set('thisid',_.string.split(URL,'/')[-2])">
<dtml-in "profil.objectValues(['Folder'])" sort=id>
<dtml-if "_['id'] == _['thisid']">
<a href="<dtml-var sequence-previous>">previous</a>
<a href="<dtml-var sequence-next>">next</a>
</dtml-if>
</dtml-in>
.... but this returns
Error Type: KeyError
Error Value: sequence-next
so it is obviuosly the wrong way of doing it.
Grateful for help!

Hi all.
I am using RESPONSE.write() for stream oriented output in a python function,
but I donīt know the length of the data so I canīt set Content-Length and
the browser donīt display anything if the Content-Length header is not set.
This is my little problem, any suggestion ?
