PARENTS and the with tag
by Alice Gutman 09 Nov '99

09 Nov '99

Hi, I'm having some scoping issues with PARENTS. It doesn't seem to acknowledge with tags or anything else. For example, if I have the folder hierarchy: A B C D E and in the index_html document of C I say: <dtml-with E> <dtml-in PARENTS> <dtml-var "_['sequence-item'].id"><br> </dtml-in> </dtml-with> it produces: C B A when I actually want: E D A And if I say: <dtml-var "E.PARENTS"> then I get an error message. What am I doing wrong? Is there an easy way to make it behave like I want it to? Thanks in advance, Alice

Subclassing problem?
by Chew Meng Kuan 09 Nov '99

09 Nov '99

I have this class called Sample that is coded in python only. This class needs to contain uploaded files. Currently, it subclasses the following: CatalogAware, OFS.SimpleItem.Item, Persistent, Implicit, AccessControl.Role.RoleManager, OFS.ObjectManager As a test, I tried the following command where sample1 is an instance of Sample: $ python Client.py -usuperuser:123 http://localhost:8080/Test/sample1/manage_addFile id="forms.html" file:file=/home/superuser/forms.html The file was added to sample1's parent folder (http://localhost:8080/Test/forms.html) instead of itself (http://localhost:8080/Test/sample1/forms.html) Why is this so? Is there any particular Class I need to subclass in order for Sample to contain File objects? Thanks, Meng Kuan

Adding objects in ZClass construcor
by Itamar Shtull-Trauring 09 Nov '99

09 Nov '99

Every time a new ObjectManager ZClass instane is created I want it to add to itself a TinyTable. So I do in Container_add: <dtml-with "Container.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "manage_addTinyTable('imglayout','', columns='name value')"> </dtml-with> But this just creates a TinyTable in the folder that I added the Container to, not in the Container itself. So how do I add objects in constructors so that it will put them in the correct place? -- Itamar - itamars(a)ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust?

I only get a empty string returned. Another question: When i am in some subfolder a/b/c of folder News, which is a direct descendant of the root folder, how do i get the id of this 'News' folder? -- Arjan Scherpenisse, A.Scherpenisse(a)zap.a2000.nl ICQ# 27592135

sqlvar
by Graham Chiu 09 Nov '99

09 Nov '99

I have noticed that I get ODBC errors if I attempt to insert character strings longer than the database field length. I can restrict the character lengths by using the maxlength attribute in the data entry forms, but would it not be better to have an attribute of sqlvar that restricts the length of strings being passed to the ODBC adapter? ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz

COMObject How-To
by Chui Tey 09 Nov '99

09 Nov '99

Has anyone had any luck with using COMObject with Zope 2.0? I installed Zope, then win32all. Next I changed the start.bat to "C:\Program Files\Python\python.exe" ... Trying connect to the COM object gives this: Error Type: com_error Error Value: (-2147221008, 'CoInitialize has not been called.', None, None) Last bits of the traceback reads: File C:\Program Files\WebGalah\lib\python\Products\COMObject\COMObject.py, line 211, in getObject (Object: FDFApp) File C:\Program Files\Python\win32com\client\__init__.py, line 13, in Dispatch File C:\Program Files\Python\win32com\client\dynamic.py, line 68, in _GetGoodDispatchAndUserName File C:\Program Files\Python\win32com\client\dynamic.py, line 58, in _GetGoodDispatch >From Python interpreter I was able to win32com.client.Dispatch com objects with no problems.

Oracle access from Zope
by N�meth Mikl�s 09 Nov '99

09 Nov '99

I am evaluating Zope, and I would like to know if there is a Zope database driver for Oracle? Is there a documentation about the services of this driver? Recently, I have been evaluating several Oracle database access interface modules for Perl, Tcl, Python, and found an interesting thing: none of these modules support calling PL/SQL procedures having array arguments (I do not speak of records or array of records because even OCI does not support record arguments). What about the Zope - Oracle module? It is very important in our case, because in our application array-argumented PL/SQL procedures are heavily used for efficiency reasons (they are really quite fast). Miklos Nemeth IQSOFT
