zcatalog and zpt question
by Mark Lilly 12 May '02

12 May '02

I have a python script which returns mybrains instances from a catalog. here's the code: return context.Tasks.Catalog({'id' : task_id}) i want to retrieve the meta data values in a template. so far i have this, which doesn't work, saying that task_name is not defined in task, even though task_name is a meta data piece in the catalog. <span tal:define="task python:root.CT.Scripts.P_Scripts.getTask('20020507125159')" tal:replace="task/task_name"></span> How do i get at the pieces of meta data in a catalog through ZPT?? Thanks, mark

image manipulation in tables
by Bill Kerr 12 May '02

12 May '02

this code creates a table with images in the first column and captions in the second column (images from a folder called Personal) how could I rewrite it so images go in the first row and captions in the second row? <dtml-in expr="Personal.objectValues('Image')"> <tr> <td> <dtml-var sequence-item> </td> <td> <dtml-var title> </td> </tr> </dtml-in> it seems hard to me - Bill

Calculations on a Date Field
by complaw＠hal-pc.org 11 May '02

11 May '02

My users are annoyed with the time shift of postings on a Squishdot site. The users are in the U.S. and the server is in the Netherlands (FreeZope.org, a truly wonderful thing). The DTML code in Squishdot that displays the date appears to be a date field in the posting object. E.g., the code is: <dtml-var date_posted> What I want to do is recalculate the date_posted and shift the time back about five hours. I tried: <dtml-let old_date=date_posted new_date="old_date - 0.25"> <dtml-var new_date> </dtml-let> But the server returned an error regarding the use of the minus sign. Does anyone have any hints? Thanks in advance, Ron

OpenOffice, Webdav question
by kent＠springfed.com 11 May '02

11 May '02

Howdy, Is anyone using OpenOffice 1.0 to edit Zope documents via Webdav? The OO doc says it is Webdav capable. In Zope doc I found mentioned that a port other than 8080 will return source of a page instead of rendered. Is there a predefined port to return source? Thanks, Kent

PIL Question
by J. Joy 11 May '02

11 May '02

I'm trying to create an external method that will take variables that exist in a ZSQL call and will output an image based on that: import Image, ImageDraw, StringIO, os.path def PILtest(): image = Image.new('RGB',[25,25]) ## IMage Stuff Happens here! return image Where this would occur in a DTML-Method of: <dtml-in SQL_COMMAND> <img src="PILtest">  </dtml-in> But I can't get PILtest to output the image itself. Save() doesn't seem to be of help directly. Anyone have any suggestions? Jason --------------------------------- Do You Yahoo!? LAUNCH - Your Yahoo! Music Experience

One (the?) solution is to pass the 'under' namespaceto the script, that is to specify _ as the value of 'bind namespace' in the Python Script. The you have access to that namespace where (I think) the variable val has been 'pushed'. To get the var out of it you can: 1) specify val as parameter and use it 'normally' ## Script (Python) "script" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters=val ##title= ## return 'script - ' + str(val) 2) do not specify it as parameters and get it explicitly from the namespace ## Script (Python) "script" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## return 'script - ' + str(val) Not really sure about the 'theory', but it works in practice. bye, Luca

Mozillla 0.9.9 and Zope authentication
by Kirk Lowery 11 May '02

11 May '02

Now, before you go and flame me for being off-topic, let me say that I've checked everywhere on the Mozilla sites, searched through Bugzilla, and come up with nothing. I just upgraded from Mozilla 0.9.8 to 1.0RC1. And the next time I tried to access my zope site, the authentication would not work for any user except for the original administrator set up during installation. And even then, the management screen would not complete uploading to the browser and would not refresh. I backed down to 0.9.9, same behavior. I backed down again to 0.9.8 and everything works. I know...I know...it's not a Zope problem, but Mozilla's. But if anyone knows about this, I'd appreciate knowing if a bug has been filed against it under what subject, and especially if there is a workaround. In the meantime, I'm just backing down to 0.9.8 again. TIA. Kirk
