Page Template tal:replace advice
by Norman Khine 14 Jul '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I am trying to generate some static pages from a database, I have created my template file, but I am have a small problem! The database has a field image, this contains the image filename, but some records don't have images at all, so my question is how to design my template so that if there is an image file, to display it, if not then not to display any image. Is this possible? This way we won't get any broken pages that don't show an image. So if I have this template, how can I include the <img tal:replace="structure images/35.gif | nothing"/> <html> <head> <title tal:content="template/title">The title</title> </head> <body> <img src="35.gif" border="0" tal:define="im container/35.gif" tal:attributes="src im/absolute_url; width im/width; height im/height; alt im/title" /> </body> </html> Thanks Norman zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz zz/********/z/****\zzz|****\*\zz|*******|z z/^^^^^^^^/z/******\zz|*^^^^|*|z|*|^^^^^|z norman khine zzzzzz/**/z|**/^^\**|z|*|zzz|*|z|*|zzzzzzz mailto:norman@khine.net zzzzz/**/zz|*|zzzz|*|z|****/*/zz|*****|zzz purley z/******/zz|*|zzzz|*|z|*|^^zzzzz|*|^^^|zzz UK zzZ/**/zzzz|**\^^/**|z|*|zzzzzzz|*|zzzzzzz zz/******/zz\******/zz|*|zzzzzzz|*|*****|z z/^^^^^^/zzzz\^^^^/zzz|^|zzzzzzz|^^^^^^^|z zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz -----BEGIN PGP SIGNATURE----- Version: PGP 7.0.4 iQA/AwUBPxL303GyKIoODyswEQKJvQCcDgoalAFFd8JQpEg7ZbCCssDEehkAn33f DMtM+LYHhoj36l36dWGThbjF =Xq79 -----END PGP SIGNATURE-----

URL of folder python product in left frame is wrong.
by Vizitiu, Ciprian 14 Jul '03

14 Jul '03

Hi listers. I'm working on a small python product that should contain different objects inside. So far so good, I've inherited from ObjectManager the object does have a folder icon and it "behaves" much like a folder object. The only strange thing is the link in the Zope's left frame: is wrong. Say my object is t1. If I make a normal folder "temp" in / and in there I create an instance of my product, the URL in the left frame should be /temp/t1. For some unknown reasons it is not, it is /temp/temp. So the only way to access my product is via the main frame of Zope. Even then the URL on top of page is wrong: "Myproduct at /temp/temp/t1" although it should have been /temp/t1. Any object inside my product-folder gets a strange PARENTS[0] but I guess it is related to the same problem. Any hints are welcome... :-|

Zope Extensions
by Patrick W. Fraley 14 Jul '03

14 Jul '03

Hi, I posted earlier a question about importing python standard modules, which I solved by using the Extension directory. Now is it possible for a script in that directory to access the context object? I do have a lot of sql routines, which I would like to access from the extension script by using the context object. When I try that I do get an error global name 'context' is not defined. Which module do I have to import in order to get access to this? TIA Patrick W.

Importing Python Packages
by Patrick W. Fraley 14 Jul '03

14 Jul '03

Hi List, I am having a little problem importing a python package in a script (I know it should be a product, but this is just a quick hack I need to get running by this afternoon). How can I get around the security checks when trying to import a python package in a python script? I found some references to creating a dummy package, but no reference on how to exactly do this or what is necessary. Please help me I need to get this done quickly. Best regards Patrick W.

Help! Zope is hanging - Issue 852 in collector?
by Craig Funk 14 Jul '03

14 Jul '03

Hi, I am new to this group, so please forgive me if this problem has been addressed in the past. I was not able to find any solution on Google or elsewhere. I am running Zope, MySQL and Plone and occasionally Zope will lockup under load. Below is the messages from the log: 2003-06-18T14: 06:31 ERROR(200) ZODB A storage error occurred during transaction abort. This shouldn't happen. Traceback (innermost last): File /xxx/2-6-1/lib/python/ZODB/Transaction.py, line 261, in commit File /xxx/2-6-1/lib/python/ZODB/Transaction.py, line 392, in _commit_error AttributeError: Surrogate instance has no attribute '_p_oid' ------ 2003-06-18T14: 06:31 ERROR(200) SiteError http://xxx/mail_password Traceback (innermost last): File /xxx/2-6-1/lib/python/ZPublisher/Publish.py, line 102, in publish File /xxx/2-6-1/lib/python/Zope/App/startup.py, line 200, in commit File /xxx/2-6-1/lib/python/ZODB/Transaction.py, line 261, in commit File /xxx/2-6-1/lib/python/ZODB/Transaction.py, line 392, in _commit_error AttributeError: Surrogate instance has no attribute '_p_oid' It happens within any ZPT, not only mail_password. After this occurs zope locks up within a minute or so. We have been getting this almost daily, and need to restart Zope when it happens. I found an unresolved issue in the zope collector ( http://collector.zope.org/Zope/852 ) which seems to be the same problem. I have found several work arounds: 1) Apparently a work around is to run Zope 2-6-0 instead of 2-6-1 . 2) Setup the tables in MySQL to support transactions. Currently our MySQL tables are not enabled for transactions. Does anyone else have experience with this issue? I have a rather large installation and am reluctant to roll back to 2-6-0 :( -- Craig Funk PanTechnica Corporation

dtml-except and whitespaces
by Nestor A. Diaz L. 14 Jul '03

14 Jul '03

Hi, Does anybody know how to deal with exceptions which include a whitespace in the name? i mean, if i define a exception like this: <dtml-raise type="Access Error" You are not autorized </dtml-raise> i want to catch it, but dtml-except can not let define a space between "Access" and "Error", i have tested the following but none of them work: <dtml-except "Access Error"> <dtml-except 'Access Error"> <dtml-except '_['Access Error']'> and so on, but i couldn't figure what is the exact sentence. Another question; does anybody knows about a good product to do form validation? Thanks, -- Nestor A. Diaz Lizarazo Tel. +57.1.6005490 Ingeniero de Sistemas y Comp.
