avoiding 'AttributeError'
by Malthe Borch 30 Mar '05

30 Mar '05

Hello list, --- I can't seem to find an elegant solution to checking if an object has a certain attribute. The following fails (i.e. zope dies), if the attribute does not exist: <p tal:condition="exists: obj/someAttribute" tal:replace="obj/someAttribute" /> Of course, I just want it to skip the tag. Dying is a bit rash. Specifically, I want to test if a certain CGI parameter has been set, i.e. that the REQUEST object has a certain attribute. What is the best way to do this in both ZPT and Python? \malthe ---- mail: mborch(a)3avod.dk blog: www.3avod.dk/blog/ crypto-key: 3avod.dk/keys/mborch.asc --------------------------------------

Mac OS X and zope (continued)
by Pavel Zaitsev 30 Mar '05

30 Mar '05

Hi, I am using OSX and my zope on powerbook still hang quite regularly, having state 'U' on list produced by 'ps aux'. If I run zope with runzope, when said 'hanging' occurs and i try to ^C kill the process zope process changes status to 'E', which man page describes as Process that trying to exit. I am wondering how would i go about debugging the zope to see which call zope hangs in , as debugging in zope.conf , did not make runzope output any more information... zope stalls quite frequently. It does not do so on my linux server. Zope hanging on my powerbook does not associate with any extensive memory/resource usage/thrashing as per statistics, or so it seems. I would like to resolve this problem with your help, thanks, Pavel

Telnet - psycopg - odbc - dbi with python in Zope
by Reddy, Niranjan Kumar (STSD) 30 Mar '05

30 Mar '05

Hi Guys, I'm a newbie to Zope .. & here's my query .. My Application Architecture : Web Interface ( submit data & Report data)<-> Python Scripts ( Uses telnetlib, psycopg, odbc modules) <-> Database ( PostgreSql ) Querying the database directly through Python is an easy job but when I try to invoke the Python scripts through Zope, there are some security restrictions in zope where in we are not allowed to access all the built-in libraries of Python like telnetlib, psycopg, dbi , odbc & so on. I went thru some of the zope mailing lists & got a work around where in one can provide the access to some but not all of the Python built-in modules using the allow_access('<module-name>') method. The access to the modules like telnetlib, psycopg, dbi , odbc is restricted even in this case. Please let me know if you have a work around for this problem. Niranjan

Presentation of CMF Topic.
by burley＠zonnet.nl 30 Mar '05

30 Mar '05

I'm using Zope's CMF (not Plone) and would like to present Topic search results in a flexilble way: i.e. as a tree structure depending on the order of search criteria used. Is this possible, and how can it be achieved? (I've used dtml-tree in the past, but, if possible, how does it integrate/interface nicely with the CMF interface?)

zpt and hrefs
by Pete Taylor 29 Mar '05

29 Mar '05

Hi all, Sorry for the newbie question, but I've scoured TFM for 2.6 and 2.7 (as much of the new book as is there), and I can't figure out how exactly to do the following. basically i'm attempting to have an href link access a python script with a particular set of parameters, have the python script call a zsql method (the only way i've found to make zpt and zsql work together when there are particular "WHERE" bits), and then return the relevant pieces back out to another zpt using the "tal:replace="options/passed_params" construct. i've tried using tal:attribute instead of href="" explicitly, but that doesn't work any better. it may just be that i'm approaching this the wrong way, in which case i'd be glad to try it another way... normal href... <code> <a href="somescript?identifier=4">link me</a> </code> but assume identifier is built dynamically, and is held in a zope repeat/replace loop like... <code> <table tal:repeat="item sequence"> <tr><td><a href="somescript?identifier=item/ret_val">link me</a></td></tr> </table> </code> obviously it doesn't work... it tries to pass the literal string "item/ret_val" to identifier. but I would imagine there's got to be a way to make that value dynamic. it works in dtml, but i'd really rather use zpt and python scripts if at all possible. is there a better way to do this, or am I just missing something obvious?
