CST with Ext.session data container (SQL)
by Milos Prudek 09 Jan '02

09 Jan '02

Hi, I would like to try CoreSessionTracking 0.9 with External data container, to store session data in a SQL table. I need this in order to pick up session data later on by a non-Zope application (IMP written in PHP). I figured that I'll need to instantiate Session Data Container. But there is no place in Session Data Container management screens to specify the SQL connection to use. OTOH, Session Data Manager has a place to specify Session Data Container. So I now have Session Data Manager pointing to correct Session Data Container, but I don't know how to point Session Data Container to a SQL table. Where can I find help? -- Milos Prudek

regular expressions with re
by Walter Pleyer 09 Jan '02

09 Jan '02

Hi folks! I have a strange little proble when I want to use the python module "re" in Zope. Importing it is no problem and works flawlessly. Compiling the re-expression also works fine. But I run into troubles as soon, as I try to do something with it. For example, I'd like to check for the @ character in an email-address. According to the python howtos it works like this: import re p=re.compile("@") m=p.match("walter(a)pleyer.com") This works fine, when I try it with a standard python interpreter. But if I try in Zope it wants my password as soon as I try the match-operation and never completes it. Any Ideas? Thanx, Walter

Adding text to DTML Method
by Oliver Erlewein 09 Jan '02

09 Jan '02

Hi I'm trying to add text to the content of a DTML Method programmatically. Somehow I can't figure out how to do it. Changing a property is easy but the content has no property name. I know that it's probably really simple but I seem to have a blackout on thisone. Thanx for the hint in advance! Oliver ;-) -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

Image Referers
by HoYin Au 09 Jan '02

09 Jan '02

How do I go about writing an access rule for images & binary data (like zip files, mp3's, wavs, etc.) that will return an access denied message if the HTTP_REFERER header doesn't match value(s) that I define? We're trying to discourage direct-linking to our images on other people's sites, but also need to have the ability to have exceptions, i.e. The image is hosted on somesite.com. Anypage from www.somesite.com, www.anysite.com (which is an affiliate), xyz.somesite.com, etc. can also link to the image. If the image isn't called from those pages, return either an access denied message, or an "Image hosted by somesite.com" image.

RE: [Zope] Is this possible in Zope?

Side note to the reponses I've seen (including my own).. You'll need to either provide graphics for, or handle as special cases, those characters for which you don't have a image, eg space, quote, etc. ---------- Keith J. Farmer kfarmer(a)thuban.org http://www.thuban.org

Make a method that will retrieve the text and convert it to a series of images. Something like: <dtml-in expr="_.len(title_or_id)"> <dtml-let letter="title_or_id[sequence-var]"> ... dtml to retrieve the appropriate image ... </dtml-let> </dtml-in> ---------- Keith J.

Hi, I'm new, so i hope this is the appropriate place. When running through the example in Ch 12 of the Zope Book (http://www.zope.org/Members/michel/ZB/CustomZopeObjects.dtml) all is well until i add the Python Script to the add object. I get the following error (the script is at the end of this note). Any thoughts? Thanks, mark PS-it has happened on two different Windows machines. ____________________________ Error Type: KeyError Error Value: parameters: id ,title, request Traceback (innermost last): File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Program Files\Zope\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook (Object: add) File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Program Files\Zope\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: ZPythonScriptHTML_editAction) File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: ZPythonScriptHTML_editAction) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 197, in ZPythonScriptHTML_editAction (Object: add) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 216, in ZPythonScript_edit (Object: add) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 451, in write (Object: add) KeyError: (see above) _____________________________ ## Script (Python) "add" ##parameters: id ,title, REQUEST=None ## """ Copy the exhibit template to the calling folder """ # Clone the template, giving it the new ID.
