Cannot "uncheck" boolean properties in 2.2b3
by Ron Bickers 21 Aug '00

21 Aug '00

In 2.2b3, after setting a boolean property to "checked", it will not save when trying to "uncheck" it. I reported this to the Collector already (751). As a workaround, you can just delete it and readd it since it defaults to unchecked. _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

Looping through a folder's contents...
by jiva＠devware.com 21 Aug '00

21 Aug '00

I would like to loop through the contents of a folder, and the contents of the subfolders of that folder. I know I can do this to a singular level by doing something like: <dtml-in "subfolder.objectValues('Folder')"> <dtml-var title> </dtml-in> Should give me a list of the titles of all the subfolders of the folder called "subfolder". So, once I get there, how do I loop through the subobjects of each of those folders? In other words, I have a subfolder inside of the folder called "subfolder" and I want to see the contents of that folder. How do I do it? -- IBM Pollyanna Principle: Machines should work. People should think.

Pages Half Rendering :(
by Chris Withers 21 Aug '00

21 Aug '00

Hi, I experienced the same weird intermittent problem yesterday that I have had on odd ocassions over the last eight months. Basically, Zope 2.1.6 returns only half a page. By that I mean if I view source, the HTML just stops at some point through the page. The point depends on the actual time, it varies... clicking reload means you get more or less of the page than last time. All very odd... what makes it worse is that it happens intermittently under certain cirumstances that I can't pin down. Yesterday was on a page that performed a ZCatalog search and returned a table of the results. It worked fine from here at NIP, but when I tried at home over dialup I got the problem. That said, I've had the same thing happen a few times in the past here at NIP, mainly where pages were raising exceptions and the error wasn't getting displayed, just some half-rendered HTML... all very confusing :S Also, totally bizarely, one of our clients had problems on the same page. Searching works fine here from NIP and at home over DSL for some NIP employees. I was trying over dialup from home but had the problem I already metnioned. However, whatever the client searched for, he got no results. The page rendered fine but it was the paeg saying 'no results could be found matching youur query'. If anyone else has experienced anything liek either of these problems, or has any idea as to what may be going on, I'd love to hear it :S cheers, Chris

dtml-let and quoting(?) or forcing to string
by Mayers, Philip J 21 Aug '00

21 Aug '00

All, I've just setup a test Zope installation. So far, very impressive. I'm using a Postgresql database containing a network hierarchy (basically, a table with a "network" column, and a "parentnet" column). I'm trying to display this with a tree view, using the following DTML: <dtml-let network="0/0"> <dtml-tree id=network branches_expr="network_children(parentnet=network)"> <b><dtml-var network></b> <dtml-var descr> </dtml-tree> </dtml-let> Where the network "0/0" is the pseudo-parent of every other network. The problem is, python (or DTML, I don't know) interprets this as a divide by zero, and it fails. The other alternative "0.0.0.0/0" also fails: Expression (Python) Syntax error: invalid syntax , for tag <dtml-let network="0.0.0.0/0">, on line 15 of test_html (I'm doing all this through the web management interface). I'm not familiar with Python (yet - the book is on it's way) but in the command-line interpreter, this works fine: >>> "0.0.0.0/0" '0.0.0.0/0' >>> "0/0" '0/0' >>> I need to cast the value to dtml-let to a string. How? I know how to do this in Perl/C/Java/Pascal, but it's not obvious to me why this isn't working. Yours, dumbly....

Broken Site Access and domain name capitalization?
by J. Atwood 21 Aug '00

21 Aug '00

I just started messing around with some of my Domain names trying caps in the name and broke right through the Site Access product. So my question is to I have to add all the variants of the domain name to the virtual_host method or is there a way to simply lowercase the HTTP_HOST before checking it? Anyone done this or shall I forge ahead? Thanks, J

Broken ZDiscussions-0.5.3 on 2.2.1b1: missing comma...
by J M Cerqueira Esteves 21 Aug '00

21 Aug '00

I tried to install ZDiscussions (ZUBB) 0.5.3 it on a Zope 2.2.1b1 and got a broken product. The traceback I got at Zope startup was: 2000-08-21T01:44:09 ERROR(200) Zope Couldn't import Products.ZDBase Traceback (innermost last): File /usr/local/lib/Zope-2.2.1b1/lib/python/OFS/Application.py, line 396, in import_products (Object: string) File /var/lib/zope/an/Products/ZDBase/__init__.py, line 86, in ? File /var/lib/zope/an/Products/ZDBase/ZDiscussions.py, line 106, in ? File /usr/local/lib/Zope-2.2.1b1/lib/python/App/class_init.py, line 109, in default__class_init__ (Object: ZDItem) File /usr/local/lib/Zope-2.2.1b1/lib/python/AccessControl/Permission.py, line 204, in registerPermissions ValueError: unpack sequence of wrong size The problem seems to be a missing comma in the definition of__ac_permissions__ in class ZDItem (file ZDiscussions.py): __ac_permissions__ = ( ('Manage properties', ('manage_addProperty', 'manage_editProperties', 'manage_delProperties', 'manage_changeProperties',)) ) Since this is lacking a comma before the last parenthesis, outer parentheses are "dropped" and it becomes as a two-element tuple: ((X,methods)) -> (X,methods) that is, a "naked" permission, instead of the intended one-element (one permission) tuple ((X,methods),). In fact, ac_permissions_ was already defined like this in ZDiscussions-0.2.0... I wonder if this was clearly noticed before 2.2.1b1, since line 204 of Permission.py (see traceback above) belongs to a new function called `registerPermissions'. This function begins with for setting in permissions: if _registerdPermission(setting[0]): continue if len(setting)==2: perm, methods = setting default = defaultDefault else: perm, methods, default = setting _registeredPermissions[perm]=1 and with the bug above, its easy to see the mess resulting when `permissions' has the above __ac_permissions__ value. Apart from this, is ZDiscussions (ZUBB) 0.5.3 fully compatible with Zope 2.2.1? I just restarted Zope after adding the comma and the product is no longer broken. Perhaps I can do some testing now...

ZCatalog and Traversable questions
by Chris Withers 21 Aug '00

21 Aug '00

Hi :-) 1. Are the paths you supply to catalog_object() supposed to start with a '/'? I think they should but I'd like some sort of confirmation :S 2. Why isn't there a Traversal Interface method to allow you to actually get the physical path of an object? (for use in cataloging them, for example ;-) I'd assumed getPhysicalPath() would do this but I see it returns a tuple :( Any ideas? cheers, Chris
