how do you write to stupid log file?
by Christopher N. Deckard 15 Jul '03

15 Jul '03

Hello, We'd like to add some internal logging for some Products we've written. What is the proper way to write error messages to the stupid log file? Is that where additional messages should go, or should we create our own log file. Thanks, -Chris -- -------------------------------------------------------------------- Christopher N.

exploratory questions
by Michael Teter 15 Jul '03

15 Jul '03

Howdy. I've followed a couple of Zope tutorials, and I really like what I see so far. Now I would like to begin to build a Zope project to potentially replace an existing project I have that's written in Java/JSP for Tomcat (and connected to PostgreSQL with a pooling mechanism). A few questions: My site has several hundred registered users, and potentially it could have many thousand. Is it practical and manageable to handle access control programmatically (assuming user info - usernames, passwords, etc.) are stored in a Postgres db)? Is there a database pooling mechanism for Zope+PostgreSQL? Does anyone have any comments about Zope performance as compared to Tomcat/Java? Any caveats? Any pointers to information are welcome. Much thanks, Michael

Hello, I'm creating a Product with a function retrieve(self, num) which returns an email.Message object. In a zpt of the product I've <div tal:define="msg python:here.retrieve(request['num'])"> and I would like to manipulate msg using email.Message methods, like in <td tal:content="python:msg.get('from')">name</td> I've added these delarations to my __init__.py ModuleSecurityInfo('email').declarePublic('Message') ModuleSecurityInfo('Message').declarePublic('get') This doesn't work, it prompts the login box. How can I use Message's methods in a page template or Python Script? Fernando

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

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.
