by Jerome Alet 16 May '01

16 May '01

Hi, I want to find if an object is an instance of OFS.DTMLDocument.DTMLDocument How can I do that in an external method ? It raises an error saying that OFS.DTMLDocument.DTMLDocument is not a class when I try with isinstance() I've searched isinstance on ZDP and Zope.org without luck except for an email message I haven't understood about extension classes. please could someone help me ? thanks in advance Jerome Alet

[Paolo Comitini <pcm@mixadlive.com>] Fwd: [Zope] Postgresql Adaptors

i just wanted to inform you that psycopg correctly convert dates into DateTime (mxDateTime to be exact) objects. it also has a modular type-casting system that allow for user-defined casting objects. if you're interested: http://initd.org/Software/psycopg/ ciao, federico ---------- Forwarded Message ---------- Subject: [Zope] Postgresql Adaptors Date: Tue, 15 May 2001 12:47:09 -0300 From: "Alex" <alex(a)quad.com.ar> To: <zope(a)zope.org> I'm migrating some code that uses ZMySQLDA to ZPoPY, and just figured out that ZPoPY does not convert datetime fields to time objects when I select them. Is there any pgsql adaptor for zope that does this convertion? (zmysqlda does it) I thought all database adaptors had some kind of standards, like data type conversion, but it doesn't look like this is the case. -- Federico Di Gregorio MIXAD LIVE Chief of Research & Technology fog(a)mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog(a)debian.org Qu'est ce que la folie?

Type Error when using ETailer
by Norman Khine 15 May '01

15 May '01

Hello, I just installed the etailor e-commerce product, on to Zope Version Zope 2.3.2b2 (binary release, python 1.5.2, win32-x86) Python Version 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] System Platform win32 Which is a Win2K and got a type error when trying to use the mailhost ie to buy a product and then send the request I got this Type Error. I then set it up on to a FreeBSD4.2 machine, thinking it is to do with the Win2K, which has Zope Version Zope 2.3.2b2 (source release, python 1.5.2, linux2) Python Version 2.0 (#2, Jan 8 2001, 16:54:34) [GCC 2.95.2 19991024 (release)] System Platform freebsd4 Traceback (innermost last): File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/home/khine/usr/local/Zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: CatalogAware) File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: buy) File /usr/home/khine/usr/local/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: buy) File /usr/home/khine/usr/local/Zope/lib/python/Products/Etailer/Cart.py, line 282, in buy (Object: Traversable) File /usr/home/khine/usr/local/Zope/lib/python/Products/Etailer/OrderManager.py, line 115, in create_order (Object: RoleManager) File /usr/home/khine/usr/local/Zope/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: <string>) File /usr/home/khine/usr/local/Zope/lib/python/DocumentTemplate/DT_Util.py, line 334, in eval (Object: style().postOrder(_.None,_)) (Info: _) File <string>, line 0, in ?

[OT] sourceforge voodoo headaches
by Jason Cunliffe 15 May '01

15 May '01

Is Sourceforge only stable when _not_ used with Internet Explorer? On a regular basis Sourceforge hangs or crashes my system when I follow a sourcforge link using latest IE5.5. But it did with previous versions too. What a headache !#$ - I never know which pages are ok and which are not.. For example: http://pybsddb.sourceforge.net/ = OK but clicking on the link to download "Source and Binary Releases" http://sourceforge.net/project/showfiles.php?group_id=13900 hangs my systrem until I ctrl+alt+del to kill that IE window. Backup and launch NS. ok loads fine. Does anyone else experience this? ./Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

dtml-with question
by Laurie Nason 15 May '01

15 May '01

Hi there, I have a little question for you gurus out there... Why does this first piece of code work when I explicitly state the folder name and the second not work when I use a variable in its place? (lookup type is set to strain) #1-------------------------------- <dtml-with name="lookups"> <dtml-with name="strain"> <dtml-in expr="objectValues()" sort="id"> <dtml-var name="id"> </dtml-in> </dtml-with> </dtml-with> #2-------------------------------- <dtml-with name="lookups"> <dtml-with name=lookuptype> <dtml-in expr="objectValues()" sort="id"> <dtml-var name="id"> </dtml-in> </dtml-with> </dtml-with> By my reckoning this should do the same thing, iterate over the contents of the strain folder and list the ids of its objects. Why isn't it working? Laurie Nason Dept. of Biochemistry - N420 Baylor College of Medicine Houston. TX77030

And > that's for really simple, ten-line test XML documents. That's way slower than what I've seen. The edit or DOM tree view of a ten-line XML document should not be noticably slower than your average Zope management page on a fast machine. I test on a 666 Mhz box with lots of other stuff going on and don't see this. If you're looking at the *collapsed* DOM tree view, ParsedXML isn't doing much at all, just getting the document element node, so slowness that you see there probably isn't ParsedXML. Access these pages and some DTML documents or whatever *on the same server with the same load* with wget or ab, and time the results. What is the difference? That being said, printing the XML is slow, which is why the default view isn't the edit window. I recommend cacheing when you're using the XML from ParsedXML. And also, yes, ParsedXML proxies the DOM in an clunky way, which is why it is often a good idea to use the proxied DOM when speed is an issue. It's a compromise. ParsedXML's proxy layer has the features, the proxied DOM has the speed, but is nothing but DOM. -- Karl Anderson karl(a)digicool.com

MSWordDocument
by Takashi Linzbichler 15 May '01

15 May '01

Hi, out there ! Has anyone got FTP and WebDAV together with MSWordDocument under Zope 2.3.x (exactly: 2.3.2) to run ? It works like a charm as long as I use only the built-in HTTP-PUT upload, but I can't upload anything via FTP or WebDAV. WebDAV and FTP are OK for all objects on the site except those of Type MSWordDocument. I always get either error 426 (cannot create file) with ftp and 405 (method not allowed) with WebDAV. Access rights shold be OK (checked several times, even tried with all rights for anyone). Funny thing is, using FTP, the *.doc file gets converted (via wvWare, I'm under Linux) correctly and the temporary *.html-file can be ound in /tmp together with the graphics. But it doesn't get published then. Using WebDAV, there's not even a conversion underway. No errors, not even in STUPID_LOG_FILE. Any help appreciated.

RE: [Zope] Will the inheritance relationship will be preserved af ter export/import?
by NABETH Thierry 15 May '01

15 May '01

Hello Iap, >> The interitance relationship seems broken after export/import between different ZODB. Following is the message I have posted about this bug in January. I have mentioned already this bug several time, but until now I seemed to be the only one that care about this bug. (which makes me ask question about how much or how little the Zope community is using object orientation and inheritance with the Dtml language). I have personally stopped all design on the Zope platform (which I find some concept very interesting), and am concentrating my effort on Java/servlets because of this bug. I hope you find some way to solve your problems. Bye, Thierry -----Original Message----- From: Thierry Nabeth [mailto:Thierry.Nabeth@insead.fr] Sent: Saturday, January 06, 2001 10:46 PM To: zope(a)zope.org Cc: Thierry Nabeth Subject: Serious BUG in Export. ==> pb of lost inheritance if export / reimport. Hello, I would like to mention a very serious bug (for me), that prevent to use inheritance between two classes defined in two different package, if you have to export and reimport those packages. In a previous mail I mentionned a problem of Inheritance lost between packages. I spent a lot of time investigating the problem, and in particular looking in the export file (xml version). First here is the test: Phase 1: create the products and the classes. Create a product PA Create a class A in the product PA. Create a method "test" in class A. (this method display "before"). Create a product PB Create a class B in the product PB which inherits from A. Create an instance a of A. Create an instance b of B. Phase 2: test the inheritance. ==> everything works fine Executing the method "test" on those two instances return. a.test ==> "before" b.test ==> "before" The result is correct. Phase 3: export / reimport product PB, and modify methode "test". Export the product PB. (PB.zexp is generated) Delete the product PB and restart zope. Import the product PB (PB.zexp) and restart zope. Modify the method "test" in class A.. (this method display "after"). Phase 4: test the inheritance. ==> B does not work correctly. Executing the method "test" on those two instances return. a.test ==> "after" b.test ==> "before" ####### this is incorect. !!!!!! I spent a lot of time investing this problem, in particular looking in the xml export file. The problem is that when you export PB, the exported file also contain the definition of class A. When you re-import PB, B inherits from a class A that is different from the class A that is in the product PA. You have a kind of Zombie class A. (note: reimporting class A doesn't solve the problem). If someone has some idea how to fix this bug which almost forbid the use of inheritance between products in zope (unless you have a master server that never import anything) ?!
