You have read the description for "branches_expr" carefully? It is the expression used by Zope to find the branches of the current object. In your case, the expression is independent from the current object. Therefore, it returns always the same branches (as you observe). Try: <dtml-tree folder_of_things branches_expr="objectValues(['Folder','DTML Document'])"> .... Dieter

"bobobase_modification_time" is a method (at least for folder), not a value. Use "_['bobobase_modification_time']" instead. Dieter

Re: [Zope] Help Debugging External Methods

Usually, I use "print" statements for debugging purposes. Under Unix, I can redirect "stdout" to a file and view the output (be sure to flush stdout after "print"). You can also use "zLog" (may be spelled differently!). This writes log entries into the log file. The advantages: will work under Windows, contains a timestamp. If the external method does not need too many Zope infrastructure, I test it outside of Zope and integrate only, when it works properly. When everything else does not work, I use "Test.py" and the Python debugger "pdb". Dieter

Can someone give me an example, either in dtml or external methods of accessing or listing the properties of the current object I am calling a method on. Or point me to a source Matt Bion

Re: [Zope] ZCatalog question. boolean and wildcards.

Sorry, the patch I posted yesterday was not complete. There have been too more problems: * if the wildcard expansion could not find matching words, my patch created an empty subquery. Such queries, unfortunately, can not be handled by "UnTextIndex.evaluate". The new patch, instead creates a new search term, 'no_expansion_for_<pattern>'. Hopefully, this term is not indexed and thus gives the same results as the empty subquery. Of cause, this is a hack. The ZCatalog maintainer should find a better solution. * The ZCatalog, more precisely, "UnTextIndex.__getitem__" still raises an "IndexError" exception, when one searches for a term that is not indexed. The result is "no data matches your query", even for an "or" query. I had already put a patch for this error in the collector for Zope 2.2.1, but apparently, DC decided not to look at it. Please discard my patch from yesterday. You may give the new patch (appended) a try.

Converting PHP3 -> Zope
by Mario Olimpio de Menezes 13 Oct '00

13 Oct '00

Hi, I'm planning to convert (migrate) a entire site from php3 to zope and i'm looking for suggestions, hints, etc on this. It's a GPL management school system done in php3+postgresql, and any user must be authenticated against a database and his privileges are those from the postgresql. The system is in portuguese (www.univates.br/sagu) if someone is interested. Does somebody have experience in such kind of migration (conversion) and can give me some "in advance" advice to avoid this or that or don't do this, etc, etc? Any comments?

Creating Recursive Folders
by Jason Spisak 13 Oct '00

13 Oct '00

Zopists, I am trying to use DTML to create folders within folders for me 3 levels deep. Two levels works, but 3 won't. For example: This works: <dtml-in expr="_.range(0, 10)"> <dtml-let a=sequence-item> <dtml-call "manage_addFolder(_.str(a), _.str(a))"> <dtml-in expr="_.range(0, 10)"> <dtml-let b=sequence-item> <dtml-call "_.getitem(_.str(a), 1).manage_addFolder(_.str(b), _.str(b))"> </dtml-let> </dtml-in> </dtml-let> </dtml-in> But this: <dtml-in expr="_.range(0, 10)"> <dtml-let a=sequence-item> <dtml-call "manage_addFolder(_.str(a), _.str(a))"> <dtml-in expr="_.range(0, 10)"> <dtml-let b=sequence-item> <dtml-call "_.getitem(_.str(a), 1).manage_addFolder(_.str(b), _.str(b))"> <dtml-in expr="_.range(0, 10)"> <dtml-call "_.getitem(_.str(a), 1)._.getitem(_.str(a), 1).manage_addFolder(_.str(_['sequence-item']), _.str(_['sequence-item']))"> </dtml-in> </dtml-let> </dtml-in> </dtml-let> </dtml-in> Throws an unathorized no matter who I am. How can I get 3 levels of recursion. I tried using 'let' to stand for the object, with no luck. BTW, I accidently sent the last post to dev, forgive me. All my best, Jason Spisak 444(a)hiretechs.com

Non-existing Zope-Security!!!
by Stephan Goeldi 13 Oct '00

13 Oct '00

OK let me state that I don't think so (subject line). I had to choose this subject, because it seems to me, that nobody was interested in my previous attempts to get information about my problem. So here is my newbie (?) question again: I have the folders: /www/folder1 /www/folder2 Apache redirects domain1 to folder1 and domain2 to folder2. The manager of folder1 is able to browse to /www and see what folders exist there. He shouldn't, because he only exists in the acl_user of /www/folder1. He even can look into the folder /www/folder2 (but not into the objects). Is it possible to disable the access for the folder1-manager above folder1? It doesn't seem to me. If it really isn't possible, there is no security at all for ISP uses of Zope. But I'm sure, there should be a possibility. I even created a local role in /www/folder1 too. Even with the local role I can browse /www and /www/folder2! Any suggestions?
