[Zope-dev] SQL-Output
Hi, i have a little problem on outputting data from an SQL-Query. The Problem is, that the user should select his own Fieldnames he want to show for output. The input form sends a request to the output form, with a query-string and some other stuff and a key named ausgabe. The key ausgabe is a sequence with all Fielnames the user clicked. Now in the outputform i have a sequence looking for the search-query. If sequence starts it prints a table-head with all selected field-names out of the second sequence ausgabe. The problem is: my table in the relational database has a column named 'Name'. If i write in the sequence at bottom dtml-var Name then the result is the the value of Namne is printed. But if i write dtml-var sequence-item and the current item is Name then Name is printed out and not the Value of Name from the DB.

[Zope-dev] Re: [Python-Dev] ExtensionClass and __radd__()?
Greg Ward wrote:
Hi all --
looks like ExtensionClass doesn't recognize/implement the '__radd__()'
protocol. Speculation below; first, a demonstration. Normal case: a
regular class Number that knows how to add itself to other number-like
things:
(demonstration snipped)
Speculation time: I'm guessing that this is similar to the problem with
'isinstance()' and ExtensionClass that I found several months ago, which
was heroically debugged by Barry. To recap, it's a mutual
finger-pointing bug: Python (Guido) can claim that it's up to
ExtensionClass (Jim) to emulate the full semantics of Python
classes/instances, but ExtensionClass can claim that Python should be
more relaxed in what it accepts as a "class object" or "instance
object".
I think the relevant code in Python is in Objects/abstract.c,
specifically 'PyNumber_Add()' and the BINOP macro:
#define BINOP(v, w, opname, ropname, thisfunc) \
if (PyInstance_Check(v) || PyInstance_Check(w)) \
return PyInstance_DoBinOp(v, w, opname, ropname, thisfunc)
[...]
PyNumber_Add(v, w)
PyObject *v, *w;
{
PySequenceMethods *m;
BINOP(v, w, "__add__", "__radd__", PyNumber_Add);
[...]
My guess is that PyInstance_Check() returns false for ExtensionClass
instances. Two possible fixes: loosen up PyInstance_Check(), or loosen
up BINOP.
Well, it's a nice theory. It doesn't explain why '__add__()' works for
ExtensionClass while '__radd__()' does not; perhaps ExtensionClass
implements that much of Python's class semantics, but doesn't go as far
as '__radd__()'.
I'd love to see __radd__ added. ;) I don't remember why it's not there.
Maybe I was just lazy. It may be fairly hard to add. I haven't looked
in quite a while. As anyone whos looked at ExtensionClass sources may
be able to tell, ExtensionClass has to play quite a few tricks to:
- Try to sanely bridge the quite different semantics of Python
"types" and "classes" (e.g. there's no radd for "types").
- Try to overcome the fact that the interpreter special-cases
InstanceType and ClassType pretty liberally. To (try to and
mostly succeed to) provide instance semantics I have to do
alot of weird indirection. This is especially hard for
numeric things.
Your analysis of the code demonstrates this issue. ExtensionClass
instances are not of type InstanceType. In fact, each ExtensionClass
is a separate type and instances of different ExtensionClasses have
different types.
Note that I just got around to responding to your earlier
post "Comparison inconsistency with ExtensionClass".
This has a similar root cause: the special-case treatment
of InstanceType.
I think that the *real* solution to this problem is to get rid
of ExtensionClass. ;) To do this, I need to get the features
I have in ExtensionClass into Python. I guess there's some hope
for that in Python 3K (love that name :).
In the mean time, I don't have time to fix the radd problem
myself, but would be willing to advise someone who wanted
to try to take it on, especially if we could work out some
phone or face-to-face sessions.

[Zope-dev] Request for amplification on new Product permissions API.
OK, I read Brian's excellent HowTo on the 2.2 Product permissions API, but it unfortunately doesn't give me the answer to my current 2.2 problem (or if it does there's something else I don't know that is preventing me from figuring it out). I'm trying to update EMarket to work under 2.2. EMarket has a shopper object. A shopper's current set of potential purchases is stored on the shopper object in a 'basket' attribute. What gets assigned to this attribute is an instance of a 'Basket' class. It inherits from Persistent and Acquisition.implicit. (Shopper, among other things, inherits from OFS.SimpleItem, by the way.) So, when I access the page that displays the current shopping cart, under 2.2 I get an unauthorized error when the dtml code attemps to access an attribute of the basket object. So, what do I need to do to allow controlled access to this object? I understand that Shopper, inheriting from SimpleItem, already has the access to unprotected subobjects flag. And I'd rather protect the object correctly, anyway grin. I tried adding an ac_permissions structure to the class, giving View permission to the attribute that is throwing the unauthorized error, but that doesn't seem to have changed the behavior. Adding the access to subobjects flag also didn't do anything. I created a new shopper/basket just in case the changes don't affect existing objects, but still got the same unauthorized error. --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

However, you can do things with buses that would take forever with a sports car, and some that are impossible (moving furniture ;) If you want the best of both worlds, map out the images and large static files from apache's config to go to itself and forward the rest over PCGI to Zope (read up on mod_rewrite). This way, the dynamic stuff is served by zope and the static stuff is handled by apache, both doing what they are good at. You can add LocalFS to Zope to allow administration of the static files too. This is what PHP does, that is just a module which handles php files, everything else is handled by Apache. PHP itself isn't that fast (it doesn't even cache compiled code). A decent 500Mhz PIII will knock out about 80 pages per second under Zope (~40 for complex things) but given that many sites where speed is important are very graphical, the ratio of a zope hit to an apache one is reasonable - on the site I'm working on this is about 1:10 and current traffic (not yet under Zope) is 18Million hits per month. If ever you run out of power (or reach the halfway point) you can start thinking of adding some caching or migrate to ZEO. In fact, if that happens, you'd be stupid not to have some sort of cluster - you'd have a very busy site!

If I copy and paste all existing methods and objects into my ZClass, do what must be done (adapt the addForm and add method, define a propertysheet, set the Views, etc...), and create an instance of my new ZClass somewhere it works but I can't view my instance: if I choose View I've got an Unauthorized error about Catalog. If I create the same ZClass without including the Catalog, then instanciate the ZClass, then add the Catalog manually to the instance, then it works fine !

In many cases, you can optimize the application if necessary, you can use caching or cache-control headers where applicable, you can use ZEO to distribute the load over multiple Zope processes, on multiple machines if need be. You could run static content from a dedicated machine, like Slashdot does. But this is not always necessary. Zope.org runs without ZEO on a sub $1000 box.

[Zope] keyword index and netscape vs ie
Hi all. I am using a keyword index as per the excellent howto. I use the following snippet to list the keywords as a series of links to further searches. (this is the objects index_html) related topics: dtml-in keywords a href="search?key=dtml-var sequence-item"dtml-var sequence-item/abr /dtml-in This works fantastic if you are using IE or a keyword is just one word. Netscape does not seem to do anything intelligent if it is a key phrase instead and returns an error.

2. Change your call to be:

At the same level, what is the easiest way to calculate the difference

[Zope] Reportlab and Zope
Hi:
In this post i report my experience with Reportlab in Zope:
1.
Install the Reportlab package in /usr/local/Zope/lib/python1.5 directory
2.
in the Zope directory i create a sub folder ./pdffiles
and:
cd /usr/local/Zope/pdffiles
su
chmod 777
3.
in the Extensions folder i create
###
#mymodule.py
###
import string
from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.pagesizes import A3, landscape
from reportlab.pdfgen.textobject import PDFTextObject
from types import *
def helloworld():
c = Canvas("./pdffiles/helloworld.pdf", pagesize=landscape(A3), bottomup=0)
c.setFont("Times-Roman", 12.0, leading=10.0)
c.drawString(100,100, "Hello World")
c.showPage()
c.save()
4.
In Zope:
External module:
ID: HelloW
function: helloworld
module: mymodule
Local File System
ID: Hello
patch: /usr/local/Zope/pdffiles
DTML Method:
ID: HelloWorld
dtml-call "HelloW"
a href="Hello" See the pdf file /a
...
My question is:
How i can insert the contents of the Local File System in to HTML environment?
Have a nice day

[Zope] Re:Web Site newbie
Tremendous reply!! Just what I needed. I'm curious about one thing tho. If you don't need a regular web server (for serving files outside of Zope), stick with the built-in ZServer. Does this mean that I have to have all my files in the zope folder? Wouldn't I want to do that anyway? Can you elaborate? I'd like to stick with the Zserver if I can but I don't want to run into any road blocks too soon down the road. -mjm winmail.dat

[Zope] Newbe question concerning using python classes and external methods
All,
I am a new Zope user and I guess I'm missing something fundemental that I
haven't been able to glean from the documentation and various "How-to's".
As a learning tool I am trying to implement one of Brian Lloyd's examples I
found on the Web implementing a GuestBook.
I suspect what I don't understand is how to write the external method that
would make use of this class (The one I have been playing with follows the
class definitions). Anyhow, I've created an an external method and call
(e.g. dtml-var guest) after which the guestBookForm is displayed. After
filling out the form and submitting it Zope does not seem able to find the
signGuestBook method. What am I doing wrong??
Other than mostly trivial examples, I haven't been able to find many
complete (working) examples of using external methods.
Thanks in advance for any help.

I needed to create 'proper' URLs with a remote wiki link, but ZWiki 0.6.1 only allowed things of the form ZWikiName:name-with-characters-only. I suppose my locale setting translates too many things to whitespace, but I'm not sure. A simple fix in the ZWikiPage.py file (sorry no diff here): find line interwikilink= r'!?((?Plocal%s):(?Premote[\w]+))' % (wikilink) replace string [\w] by [A-Za-z0-9/:@_~#=\.\-\?] (note I couldn't include the % char because it seems to provoke the need for another string). Remaining question. Does anyone have a fix for the incorrect rendering of [notzwikiname] to nested URL a href=notzwikinamea href=notzwikinamenotzwikiname/a/a or do I have to fix that for myself? This also fails to work as a remote wiki link, and I thought a fix for one might be a fix for the other also. Thanks.

Re: [Zope] Python or DTML
The Zope core is *written* in python (with hotspots coded in python modules written in C), not just integrated with it. Since DTML must be interpreted by the Zope core (an interpreter running in an interpreter), whereas the python code in an external method is simply (more or less) executed (just one interpretation level), I would expect external methods and python products to be a lot faster than the same functionality coded in DTML. But I'm speculating here based only on my current mental model of how Zope works, so I could be wrong grin. I agree, again Im no expert, but from what I understand DTML is parsed into Python and then executed. You can skip that step altogether by not using DTML. I also find DTML is rather painful and anything involving 5 or 6 lines of DTML can be coded in *less* lines of more efficient Python! ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

You will have to let the persistance machinery know that you changed the

track
inmutable objects automatically. See the ZODB docs:

choose Persitent Objects, then Persitent in the bottom-left frame).
You should either treat the dictionary as immutable:
data = self._map
data.append(foo)
self._map = data
or set a special flag to let the ZODB know the objetc has changed:
self._map.append(foo)
self._p_changed = 1
You could also replace the dictionary by a PersitentMapping instance. See
above docs for more info.

[Zope] FSSession buglette
Hi All, I had some real problems with FSSession tonight. The first problem was when the FSSession tried to load, it would get an error along the lines of failed to import Acquisition. Next step was when the user session tried to rename and the file wasn't there. This threw in error in a Zope commit transaction, and rendered the site useless until a restart was performed (this was correct action by Zope, i.e. all commits are blocked to avoid the database becoming more screwed after a commit fails). First thing I did was put a try around the dump to stop it from throwing an error if the file doesn't exist. This is certainly a preferred option for us, as it does not affect the function of the FSSession at all (Except that one session is obviously now duff). Second thing in tracking down the culprit, I finally figured out that what I was doing was quite naughty. Basically creating an option for the user to return to the site and have his/her name already entered into the login screen. The mistake was putting AUTHENTICATED_USER into FSSession, it basically tried to store the object, when all I wanted was the string username! Oops!

Notice the (potentially) essential difference:
In "callproc" you use "addarticle" (i.e. all lowercase),
but in "getSource" you use "ADDARTICLE" (i.e. all uppercase).
Maybe, case is essential.

Re: [Zope] Sql result searchs with Z Catalog
[EMAIL PROTECTED] writes: I need to somehow populate an ZCatalog index with the results of a Z SQL Method. If you are familiar with ColdFusion, it needs to have the same functionality as a Verity search on a collection (custom indexed from a query). I am having trouble seeing how this might be accomplished. You asked this question already several times. I did not answer, because I do not understand why you may want to do this. I cannot imagine why someone wants to emulate a fast relational search by a (comparatively) slow ZCatalog search. Thus, I must miss something. Anyway. ZCatalog is happy to catalog anything that is URL addressable. Using direct traversal (-- Z SQL User Guide) you can make database records URL addressable. You probably will need an explicit loop over your query result set and call "catalogObject" for each of them.

[Zope] Nested dtml-in loops (was: [Zope-dev] SQL-Output)
Andre Schubert writes:
... problem with names clashes from nested dtml-in loop ...
Your problem may be generalized:
-- l1 and l2 are sequences --
dtml-in l1
dtml-in l2
-- here you need to access both components from both the
inner and the outer dtml-in
There may be a name clash between the two (implicite) loop variables
--
/dtml-in l2
/dtml-in l1
You can use renaming to avoid any clashed.
I demonstrate it for "sequence-item".
dtml-in l1
dtml-let outer_lv=sequence-item -- ATTENTION: calls it! --
dtml-in l2
...
dtml-var outer_lv -- the outer loop value --
dtml-var sequence-item -- the inner loop value --
...
/dtml-in l2
/dtml-let
/dtml-in l1
If you want to prevent the outer loop value to be called,
you may use "_.getitem('sequence-item')" rathen than just
sequence-item.

RE: [Zope] NOTICE: issue with database packing in current Zope releases
Brian Lloyd writes: Jim found a problem with the algorithm for packing the Zope database that we wanted to announce so that folks can avoid being bitten by it until the fix is out (in b4). I think this is a candidate for a Hotfix. 2.2 upgrades could be problematic and I think we might continue to see large numbers of 2.1.6 users until all the products run happily on it. Hm - the goal I had for Hotfixes was to address imperative problems that couldn't really be addressed any other way. I'm not sure that this _quite_ makes the grade in my opinion (but I could probably be convinced). For example, a security problem _demands_ a hotfix-type solution because you can't tell the crackers out there "dont do that!". In this case, there is a clear way to avoid the problem that *is* under your control and a clear way to recover in case you forget :) It definitely is not an issue for me, because my Zope Sites are still small (I never did pack up to now). But large Zope sites with lots of temporary objects may need repacking before they consume too much disk space. Maybe, a patch would be a compromise. Sites that need to care can apply the patch. Those that do not, simply ignore it. The patch could be announced with the problem report.

[Zope] RE:How do I merge form URL vars into sql easily
Hi Jake, I originally had trouble coming to grips with the concept of variables and forms and passing them from one object to the next. After much testing, trial and error (and guidance from this list), I came up with these conclusions (which I'm sure someone will shoot down if I am wrong): 1) The request object you are setting with your REQUEST.set command is like a big bucket that gets passed between one web page and the next when you call it in your DTML. The best thing someone ever showed me was how to view in the called document ie. insert the line: dtml-var REQUEST into the dtml/method you are trying to call. If you do that you can see all of the variables that get passed normally as part of your REQUEST variable, as well as any that get added to it by your form in the act of your POST command in the form. Be prepared - it is a long list! You should be able to see all your form variables in there. If you don't then you haven't been doing your form correctly (been there done that too!). The only real 'nasty' I have come across so far id the checkbox - if it is unchecked it doesn't post anything to the REQUEST object, and then you need to check for it and set it, if you are using it to update an SQL database (this is the only time I use the dtml-call "REQUEST.set['argument','value']"command.

I would think that there is some way to let the sql method see these varibles that are defined within my document. Or loop through all URL or form varibles defined and sets all the vars in request.

Re: [Zope] newbie questions
Hi Frank, It sounds like your SourceSafe tie in could potentially be a fairly complex undertaking. Amos Latteier wrote an example COMObject product that will show you the mechanics of utilizing COM objects from Zope. This might help. And though I know you don't want to VC Zope objects, you might be interested in Steve Spicklemire's CVSMixin product that seems to utilize CVS for version control of several kinds of Zope objects. You may get tips from both of these products. Seach Zope.org for both. To back up the ZODB, just copy the Data.fs file in the var directory. You may safely do this while Zope is running. To restore, reinstall Zope and all the products you're using and copy the Data.fs into the var directory.

[Zope] Unable to upload images from client to server
Hello All!
I have this problem with "UPLOADING".
In my HTML form (DTML-embedded-Document) I have data and images to insert
into a mySQL DATABASE. Therefore I'm calling SQL statements from my DTML
METHOD.
However, it seems the SQL insert command does not allow LOAD_FILE procedure
as does the SQL update command e.g.:
UPDATE table_name
SET blob_column=LOAD_FILE('full_path_of_file') WHERE
table_column='table_column value'
So I had to resort to using TWO separate SQL methods :
1) to insert the "data" alone into the database first, from the form;
2) then another to insert the image of the same form using the SQL "update"
command, verified my the data record's unique id.
All this works fine but this method does not work with the
...ENCTYPE="multipart/form-data"... value at the html form header.
Instead it only works with
...ENCTYPE="application/w-xxx-form-urlencoded" If I use
"multipart/form-data" it will enter the string of the command
LOAD_FILE('...file...') instead of the actual image contents. Why is this?
This is only one small part which I'm puzzled about as this method would
only allow images on the server's harddisk to be uploaded. The main concern
is UPLOADING from the client.
Having mentioned so, the next problem I'm facing is uploading the file onto
the Zope Server from the client. Having searched on the net, it appears
that I will have to use CGI's on my server side to temporarily grab the
files contents and place it somewhere. Is there anyway to use DTML without
the involvement of external CGI's?
Also, it seems that if I had to do this on Zope, it will require me to use
Python. Which of course sounds hard.
Then the questions arise regarding CGI's (IF IT REALLY IS REQUIRED):
1) How on earth do I do this?;
2) What if there were multiple users uploading files at the same time, then
what happens to the single temporary file which stores the uploaded files'
contents.
3) If I were to use a /cgi-bin/... how will that relate to where ZOPE is
installed, in other words, would the directory structures get confusing?
I'm not a hopeless programmer but neither am I close to even "quite good".
Learning won't be a problem, but I'll need the answers quick, as I do not
have the time in my hands. Can anyone please help me out?
I've looked in discussion forums and the DTML reference, as I have said I'm
practically a beginner programmer, and was unable to understand even half
of what had been posted.

Data.fs only gets appended to, and Zope is smart enough to ignore incomplete transactions on the end of the file when it starts up. So the database is *always* in a consistent state on disk from Zope's point of view, making it safe to back it up by just copying the live Data.fs. --RDM ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Is Zope slow?
Hello, I'm considering using Zope as the development tool for my next web project. However, I read from a recent benchmark test (from Qube, i think) that Zope(running thru Zserver?) is much SLOWER than Apache and AOLserver. Is that true? To all Zope users and 'guru's, what is yr experience using Zope? I run the QubeQuorner weblog where those numbers came from. Zope isn't slow. It's slower than Apache serving static pages. But Zope is dynamic. I haven't yet had time to do proper dynamic comparisons between the various servers. I run a few Zope sites. And I'm adding more Zope sites. I wouldn't do that if I thought it was too slow. There is a lot involved in making a site faster or slower. Adding a few graphics to your web page is going to make it slower than an all-text page. An all-text page vs a mixed text and graphics page can be almost twice as fast. Your connection to the site is going to affect "apparent" performance. For example, while I have a cable modem at home, and my Zope server sits on a fast T1 (there are slow T1s and fast ones), the connection in the evenings is too slow for me use my server. That's @Home's fault, not Zope's. And our T1 will fill up well before Zope runs out of steam on my box. Technocrat.net is a Zope site. They were Slashdotted and survived without any apparent problems. And they were running Zope on a Pentium 120! I believe they upgraded to a PII-450 after that episode, just to be safe. I have a list of Pystone benchmarks on my QQ site too: http://weblogs.userland.com/qube/stories/storyReader$289 A PIII-850 gives tremendous Python performance, which should translate to impressive Zope numbers too. Zope.org, however, doesn't run on nearly the fastest hardware available, and it rarely seems slow to me.

Starting and stopping Zope from command line - no problem, but when i chose to Shutodwn from the Zope Control Panel, it complained of an error (printed below): --- Traceback (innermost last): File /usr/local/Zope-2.1.6/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope-2.1.6/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope-2.1.6/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope-2.1.6/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_shutdown) File /usr/local/Zope-2.1.6/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_shutdown) File /usr/local/Zope-2.1.6/lib/python/App/ApplicationManager.py, line 330, in manage_shutdown (Object: ElementWithAttributes) SystemExit: 0 -- I also tried installing the Zope Tutorial, but adding the product was not successful. Is the tutorial still "raw" and may be troublesome to install?

[Zope] Stability - can you give us some advice?
Hi, I'm new to this list (to Zope too!)and I'm really impressed with its traffic. This show us that this project is in active development. In our company we are currently working to create a Web site with lots of dynamic content, database access, webmail, etc.. so we decided to try Zope. Although it's lack of documentation ( this would not be fair, with a search engine we can dig out lots of useful info from the web) we experienced a very fast development cycle. Now we're concerned about its stability. We are almost finishing the first stage of project and some times Zope hangs. It was working ok, and then, all of a sudden, it just stops answers requests. Last time it happend we changed a DTML Method to a DTML Document and it worked again (if you like i'll try to tell you exactly what was happenning). So, I'd like some advice to make it more stable. ( or tell me what i might be doing wrong) Our environment: OS: Debian GNU/Linux 2.2 (Potato) - Kernel 2.2.16 Plataform: Dual PentiumIII - ASUS motherboard - scsi Adaptec AIC-7892) Python: got from Debian - python-base_1.5.2-10_i386.deb Zope: got from Debian - zope_2.1.6-5_i386.deb DB: Postgresql V7.0.2 - compiled and installed by hand - tools from Debian, (make,gcc,..)

Some questions: (with stability in mind..) 1) Should we try Zope 2.2.0b3 instead of 2.1.6 ? 2) Should we avoid using packaged versions of Zope? 3) Should we try ZPoPyDA as a DA to Postgresql? 4) Could you give us some advices on good DTML coding: what should we avoid doing, what is a must, for example, whether or not (or when) to generate urls for objects (http://www.zope.org/Members/jim/ObjectURLs) Thanks a lot for your attention, Tacio AGSantos [EMAIL PROTECTED] ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Patch to DateTime.py
Greetings, In my current project, I have to print a lot of dates. Fine, not a problem... _.DateTime().strftime() is just the method, right? Wrong. The people who want this site want the local time, not UTC+0 that strftime enforces. So, I created a tiny patch which adds _.DateTime().strfltime(), which works identically, except it passes LOCALTIME instead of GMTIME. It's tiny, it's simple, but it's REALLY HANDY! Have a better one, Curtis Maloney. dtml-var standard_work_disclaimer 1183a1184,1185 def strfltime(self, format): return strftime(format, localtime(self.timeTime()))
Re: [Zope] Problem calling SESSION object
Ugh. This is a stupid bug on my part. Upgrade to 0.2.9 Anthony [EMAIL PROTECTED] wrote Hi All, Need Help. I'm currently using SQLSession v 0.2.3, with access database ( I had changed the "value" filed in session_data to item_value and also all sql statements that refer to it). I had no problem generate the session id, but however, I had problem calling session object after I insert it into session_data. I got an error when calling the dtml-var "SESSION['xxx']", i got this : Zope Error Zope has encountered an error while publishing this resource.

( or tell me what i might be doing wrong) Funny you should mention that. We just had a similar thing happen to us this morning. We have an installation of Zope 2.1.6 running on Red Hat Linux 6.0 on an old 486/66 machine (a prototype serving some intranet content). We aren't doing any database connections on it (through Zope, that is), but we are running Squishdot (which is the main application in terms of usage on this particular machine). Zope is running behind Apache 1.3.9, and I noticed that multiple instances of Zope.cgi started up to service incoming requests, but apparently Zope wasn't responding. I just restarted Apache and everything was fine again. Is this a known problem with Zope that has been addressed in 2.2? Thanks.

Re: [Zope] Problems shutting down Zope
This is a 'normal' message. Zope 2.2 releases suppress the error message on shutdown. Not sure what's up with the tutorial. You may want to try the latest 2.2 beta release as the tutorial comes preinstalled. Firestar wrote: Hi, i have just installed Zope-2.1.6 on a linux server.
