[Zope-dev] sqlvar and longs
Hi all, I have a little question on . My problem is, that i want to insert values into a table and the type of the values are integer8. I tried with but it doesnt work. How can i use with longs? Will this feature be added in further versions? Is there a product which patches this problem? If not i would write such a thing myself.

[Zope-dev] Zope process working directory
Ive recently noticed that Zope doesnt change its working directory when it starts up. This has been a minor inconvenience for me recently when I wanted to get a core dump from a long-running Zope, but its working directory was set for somewhere that it couldnt write. I know I could fix this in all of my start scripts, but I think it would be much nicer if Zope always changed its working directory to var on startup (except if the debug flag is set I suppose). This would be in keeping with the tradition for Unix daemons and Windows services. Any thoughts?

[Zope-dev] two hard questions
Firstly, I'm trying to return a lazy list to a dtml-in, but it seems that the __getitems__ are all called up front This is the class and the print statement shows up in debugging before any debugging output from within the dtml-in: class LazyList: def __init__(self, root, selections): self._root = root self._selections = selections def __getitem__(self, index): s = self._selections[index] print s.getPath() # this is executed for all items before anythingwithin the dtml-in o = self._root.restrictedTraverse(s.getPath()) o.setSelection(s) return o def __len__(self): return len(self._selections) Does this mean that dmtl-in touches all of the objects first for some reason? Or am I missing something? Second hard ?. Is there any way to wrap a Folder subclassed instance within another class so that I can override some methods on an instance by instance basis? I tried doing a .__class__ replacement, but for whatever reason, Zope machinery seems to keep it from taking effect. Any ideas?

If you do so, please check with me for the newest version of Ordered Folder. I have added a few features to OrderedFolder that I need for Kontentor. Some of them might be candidates for Zope 2.6, others maybe not. Currently, OrderedFolder has: - ordering support - filters (from the FolderFilter Product) - a maximum items support (not fully implemented yet) - properties to define a custom icon and MetaType - integrated "transparency" as an option (from Transparent Folders) - subobject type support Cheers Joachim ___ 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 )

I've tried about 5 different approaches to no avail :( I'm not sure how (or why) you would wrap a class around an instance. In order to override methods on an instance by instance basis, you would most probably need to create a object proxy wrapper that override __getattr__ so that it can fire off the right methods. If these methods are accessed TTW, then you could just use __bobo_traverse__ for this too. Maybe restate the problem in a different way. /---\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association [EMAIL PROTECTED] \---/ ___ 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 )

[Zope-dev] WebDAV quibble -- fix in 2.6?
This maybe more 2.6 (or even 2.5.1 final) fodder: I notice that in a vanilla Zope install, Anonymous users are allowed access through WebDAV. This is bad for two reasons: 1. From a security perspective this discloses way too much information about your site to the outside world. 2. Due to vagarities of WebDAV authentication, it makes it impossible to edit anything, because I guess the WebDAV implementation is too stupid to force a login when you try to lock something as anonymous (instead is returns a 500 server error). To get around this you have to create or copy an object to force a login. This problem disappears if everyone must login to access WebDAV at all. So the question is: Is there a good reason why WebDAV access is granted to anonymous by default? If not I vote we change it. /---\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association [EMAIL PROTECTED] \---/ ___ 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 )

Hi :-) In certain circumstances, if you install OrderedFolder (0.5.1 is last I checked) without ZBabel, *all* of the buttons on the main OrderedFolder management page will have "None" for their label. I have not had time to narrow down what those "certain circumstances" are, but my iMeme FreeBSD Zope does exhibit the error, and my Windows box does not. When I have a second to breathe I'll try it on Linux with a completely clean Zope install. One other beta tester of VirtualHostFolder reported this error with OrderedFolder; I have not gathered information from him as to his OS etc. It may also occur only when you configure OrderedFolder in a certain way. My beta tester reported that if you installed ZBabel the problem went away. I have not tested this on my FreeBSD Zope. So--who knows. This needs some testing, if nothing else. I'll get around to it when I can, because Stephan said he was unable to replicate the error. Obviously, I didn't exactly give the most complete bug report ever. It may be an interaction problem or anything. It looks like I won't have much of a chance to look at this myself until next week.

What browser are you using? Strange things like this happen for me occasionally after a Mozilla upgrade, but I just delete the cookies for the site and everything goes back to normal. I figure someone at Netscape is just fiddling with the cookie code. :-) OTOH, the only way a loop on the login page can happen is if you're not allowed to access the login page, or perhaps one of its images.

RE: [Zope-dev] Zope 2.6 and OrderedFolders

Hey Stephan. Makes sense. Maybe that would imply either a different name
for the core product ("OrderedFolderLite" is a bad example of the idea, for
instance) or some other similar accommodation for the fact that your full
product will certainly still be needed/wanted in certain cases.
I'd feel comfortable extracting the ordering stuff into a new "lite"
product, if you wanted, but I have not looked at the limiting functionality.
Do you or Joachim have time to do this yourselves, or to be a part of this
somehow?
Finally, is there any feeling for just adding the ordering functionality to
the standard Zope folder/ObjectManager? Perhaps including a button and an
API to hide/show the ordering tools? What do folks think?

Fortunately, there is a work around: Add a class level definition for "socket" before "__getattr__" socket= None def __getattr__(self,attr): return getattr(self.socket,attr) In your problematic case, this will raise an AttributeError instead of an "recursion depth exceeded". This is much better.

We recently looked at OrderedFolder, thinking to subclass it to produce our Slideshow product. The idea was to make a lightweight web-based replacement for PowerPoint where you can define the order of the slides and can hide/show them individually. We found that it was actually easier to create our own "OrderedFolder" base class and subclass it rather than use OF because of the extra functionality we did not want. Of course, the extra functionality is probably really useful for some people. My vote would be to include _some_ additional functionality like defined orderings in the Zope3 core, and keep OF as a third party extension product which people can use or not. The Zope3 version of OF would then be simpler, as it would only have the remaining functionality (like "reverse" acquisition, setting a max limit on number of items, etc.) To summarize, I would like to see regular Zope Folders enhanced to optionally have some notion of type ( a la Brian's Zope 2.6 proposal "Object Type Assocation And Death To index_html" ) and basic ordering I am willing to help out.

[Zope-dev] ZPT: how to access property sheet of custom ZClass
Hi! I'm implementing a simple db, using the same methods in the JobBoard example. I looked at Kube, but I'd like something a bit more generic. I'm trying to make add/edit forms and display pages as simple as possible. Rather than have custom versions of all of these, each with copies of the same property names, I'd like to pull the property/attribute names from the property sheet of the ZClass in the Product I added. Something like: The above example is probably very wrong for many reasons-- it shows my lack of experience with TAL, python and Zope innards in general -- but I think it conveys what I'm trying to do. I'm not sure if I can use "python:object.attrs()", or even if the objects under Control Panel are accessible to ZPT as the above example produces a guarded_getattr error. Also, is there a more generic or elegant way to refer to the record_default_properties object? Any help would be much appreciated!
