Hi, Say I've got two objects: class MyFolder(OFS.Folder.Folder,ExtensionClass.Base): def __init__(self,language): self.id = language self.language = language and below that one in the zope hierachy, a: class MyText(Acquisition.Implicit, OFS.SimpleItem.Item, Persistent, AccessControl.Role.RoleManager): def foo(self): return self.language howcome foo() fails to return the language-value? If I use the property sheet in zope to add a "language" property, it works fine. best regards, Jacob

That did the trick, thanks! > ImportError: No module named oci_ The oci code is built into a shared library named oci_.so. The Makefile leaves the file in the src directory, which is where the test script is located. Since the two files are in the same place the test script works fine. For production, though, you need to copy/move *.so from the src directory to the DCOracle directory so that it will be found when ZOracleDA imports DCOracle.

I think from discussions with Chris Petrilli at IPC8 that DC has a solution to this one on the "near term" track (it is a show-stopper for many uses of Versions). The core of the idea is to reify the individual nodes within the Catalog, so that a change to a CatalogAware object within a Version locks only that node, rather than the whole catalog. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Problem with Oracle DA on Solaris / Sparc
by Spicklemire, Jerry 08 Feb '00

Hi Folks, We're getting this traceback from the "ZOracleDA (Broken product ZOracleDA)" item under the Product Management folder of the Zope Control Panel. ZOracleDA Import Traceback Traceback (innermost last): File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/OFS/Application.py", line 387, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/Products/ZOracleDA/__init__.py ", line 103, in ? import DA File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/Products/ZOracleDA/DA.py", line 103, in ? from db import DB File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/Products/ZOracleDA/db.py", line 101, in ? import DCOracle, DateTime File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/Products/ZOracleDA/DCOracle/__ init__.py", line 66, in ? from ocidb import Connect, error File "/i01/Zope-2.1.3-solaris-2.6-sparc/lib/python/Products/ZOracleDA/DCOracle/oc idb.py", line 50, in ? import oci_, ociCurs, ociProc ImportError: No module named oci_ The Oracle DA test script seemed to work fine, connecting with no error message. Since the test script also calls oci_ it seems that linking and compiling have been successful. Still, Zope that fails to find the module on startup. I did notice that there are lots of mudules, both .py files and source code that start with "oci_", but none that I could find named just "oci_". Thanks for any suggestions, Jerry S.

So make that a parameter in the dtml-var call: <dtml-var a/b Semantics=url> and follow up with some shortcut tags: <dtml-var-url a/b> or <dtml-url a/b> etc.

Re: [Zope] Parse a file

Pedro, You can't use DTML to do this... you need to instead use Python by constructing an External Method. Please see the External Method HowTo at http://www.zope.org/Documentation/How-To/ExternalMethods You may want to pick up a copy of "Learning Python" by Mark Lutz and David Ascher (O'Reilly Books) also...

XML Document Navigator
by Tres Seaver 08 Feb '00

08 Feb '00

I threw together a couple of DTML Methods for adding a "management interface" of sorts to XML Documents (simple two-frame-tree-and-details). I set it up as a Product (not yet catalogued), but perhaps it belongs in the main XML Document distribution? or something like it, anyway. Here is the Software Product: http://www.zope.org/Members/tseaver/XML_Navigator ToDo's * Facilitate display of "non-attribute" data (CDATA, etc.) perhaps in a third frame? * Add hooks for deploying custom detail views, indexed by the element type. * Make it "purty". Let me know what you think. Tres. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com
