WebDAV locking module?
by richard＠bizarsoftware.com.au 20 Apr '01

20 Apr '01

Colour me confused... I just downloaded the 2.3.2 beta tarball and tried to run our application against it. It appears that the locking module (webdav.Lockable) is missing from webdav. We develop against the CVS, and the file is there. It has been since 2.3.1 CVS - though the 2.3.1 tarball doesn't seem to have the module either... Can someone clue me in please?

Zope options order sensitive
by Chris Gray 20 Apr '01

20 Apr '01

I'm just beginning my study of the zope source. Going through z2.py I noticed that order matters in specifying command line options. For instance: ./start -a 127.0.0.1 -P 8000 sets HTTP_PORT to: [('127.0.0.1', '8080')] but: ./start -P 8000 -a 127.0.0.1 sets HTTP_PORT to: [('', '8080')] I'm not far enough along yet to know if this makes a difference in the end. Does it? Chris

DTMLFiles are supposed to function as *methods* of their classes; methods *don't* have their own 'absolute_url', but return the url of the object on which they are called. DTMLMethods have exactly the same semantics: <dtml-var absolute_url> returns the folder/context object's URL, by design.

ZSQL and Normalized databases (or why ZSQL sucks)
by The Doctor What 20 Apr '01

20 Apr '01

Does any one have an example of ZSQL being used witha normalized database? Or is ZSQL just useless? Near as I can tell, between: * Broken type marshalling * Loosing the variable between the form and dtml-if * Inability to handle table.field names for variables * And enough flexibility to work around the above problems This makes ZSQL extreamely nasty, and impossible to use with a normalized database. What's the point? ZSQL sucks, how do I talk to the DB directly? Yeah, I keep almost getting this to be useful. But damn it if I don't keep hitting a brick wall. And there are no complete examples or demos that I can find to load up. Irritatedly yours, DocWhat -- I don't want to achieve immortality through my work...

how to add to the pythonscript allowed import list?
by R. David Murray 19 Apr '01

19 Apr '01

I've got a little Product that does some init hacks. One of the things I want to do is expose a couple of python fuctions such that they can be imported into pythonscripts. After much spelunking in the mailing list and the PythonMethods wiki on zope.org, I *think* that what I need to do is something like this: ---------------------- from AccessControl import ModuleSecurityInfo security = ModuleSecurityInfo() security.declarePublic('SignedEditions') security.declarePublic('stripCardNum','verifyCardNumber') from cccheck import stripCardNum, verifyCardNumber security.apply(globals()) ---------------------- Now, that SignedEditions one is my attempt to solve the following error message when I attempt to do 'from SignedEditions import stripCardNum': Error Type: ImportError Error Value: import of "SignedEditions" is unauthorized However, it does not solve the problem. Hmm. I just noticed that I forgot to prefix that with "Products.". Which would seem to make that error message a bug, since SignedEditions shouldn't exist in the import path. If I do from Products.SignedEditions import stripCardNum then ZDebug tells me: Unauthorized: Access denied for <module 'Products.SignedEditions' from '/usr/local/zope/sites/signededitions/Products/SignedEditions/__init__.py'> because its container, <module 'Products' from '/usr/local/zope/Zope231b1/lib/python/Products/__init__.pyc'>, has no security assertions. What do I need to do to assert that it is OK to import from the SignedEditions product? The wiki does not seem to address this question at all, though it implies that it is possible, since it *does* talk about the above assertions to declare things *inside* the product as importable. (Oh, BTW, I tried changing 'security' to "ZopeSecurity", but that didn't seem to change the behavior). --RDM

I have actually done this for a Product I am developing. It allows you to accumulate property changes and reindex only once. Supposedly, the Catalog is more efficient in this regard anyway as of 2.3. > I guess that you could build this kind of functionality into CatalogAware, > but I'm generally in favour of having flexible and optional rather than > automatic reindexing, and just adding documentation to discuss some of the > different cases. > > You could hack Property Sheet Interface to add a call to reindex if the > ZClass is catalog aware. I would not want to make PropertyManager directly aware of CatalogAware if I could get away with it. Perhaps the way to deal with this is to have PropertyManager call a hookable method afterChangeProperties or some such, passing a list of properties changed. Then your ZClass could simply call reindex_object if it feels it is necessary. That would give full disclosure and behavior control back to your specific implementation. But it would simultaneously cover property changes made in the management screens and everywhere else. I am moving this discussion over to zope-dev to see if anyone else there has any ideas. -- | Casey Duncan | Kaivo, Inc. | cduncan(a)kaivo.com `------------------>

by Stephan Richter 19 Apr '01

19 Apr '01

Hello everyone, SmartObjects (at http://demo.iuveno-net.de/iuveno/Products/SmartObjects) is not longer only an idea but we are going into some serious design discussions and plan to have our first release at the beginning of June (see release schedule). Since we want to make the framework as flexible and user-friendly as possible, we would love to get input on the design and hear about new ideas. Furthermore, we need developers, who would like to help!!! The project is totally Open Source. So, if you are interested, go to http://demo.iuveno-net.de/iuveno/Products/SmartObjects and look around. If you like what you see, just sign up for the mailing list and join our discussion.
