sorting based on object url
by Parikh, Jay 14 Mar '01

14 Mar '01

I have a simple ZCatalog that I am trying to sort via the path of the objects. I have the following so far, and it doesn't seem to work. <dtml-in catalog sort="catalog.getpath(data_record_id_)" size=50 start=query_start> ... </dtml-in> Thanks in advance.

FTP and nested ZClasses
by John R. Daily 14 Mar '01

14 Mar '01

I'm running into problems with nested ZClasses and the FTP server in 2.3.0. Most significant problem: if I have a ZClass defined within another ZClass in a Product, I can't access the methods directory of the nested ZClass. The FTP server returns a 550, "No such directory". I've tried this with ange-ftp, lftp, and generic ftp. I haven't yet reported it to the Collector, in hopes I'm just missing something obvious. Other annoyances: What's up with the trailing space after nested class names? Finally, why doesn't the FTP server recognize a renamed file as a Python Script when it has ## Script (Python) "private_create_component" at the top? -- -- John R.

XML Document
by Andreas Tille 14 Mar '01

14 Mar '01

Hello, I would like to package FreePM (http://www.freepm.org) for Debian. This package depends from XMLDocument which I found at http://www.zope.org/Members/jerome/ZCPL/Products/XMLDocument/XMLDocument-1.… . Unfortunately this file doesn't contain the slightes hint about the author of this package nor a license. This permits distributing it in Debian. Could someone enlighten me about authorship so I can ask for a valid license? Kind regards Andreas.

problem with Zope and IE and ReportLab
by Jerome Alet 14 Mar '01

14 Mar '01

Hi, not sure if the problem comes from ReportLab, in fact I'm almost sure it doesn't. However I post it to both RL and Zope lists to be sure to have an answer. here's the problem: With the help I've received yesterday from the RL list, I've managed to create an external method which generates a PDF document with RL. This external method, rpdf, is called from a DTML method which does (exactly) the following: --- CUT --- <dtml-call "RESPONSE.setHeader('Content-Type', 'application/pdf')"> <dtml-call "RESPONSE.setHeader('Content-Disposition', 'attachment; filename=rapport.pdf')"> <dtml-var rpdf> --- CUT --- When viewed in Netscape 4.76 under Linux, all works fine, and a dialog box opens, asking me to save the PDF file as "rapport.pdf", or if I've got acroread installed as a plugin on the machine, automatically launches it and all is fine and works flawlessly. When viewed under Internet Explorer 5.0 under Windows NT 4 (sp5), the dialog box opens but IE tells me it can't download the file. Unfortunately I don't have Netscape under Windows installed to make more tests. Does someone see where the problem comes from ? Thanks in advance.

Scripting Netscape Composer?
by Paul Browning 14 Mar '01

14 Mar '01

(Not strictly a Zope question but you're all such clever people and I'd like to try and integrate things with a Zope back-end.) Question: I'd like to be able to cause Netscape Composer to open from Netscape (the browser) if a link (called, say, "Edit This Page") was selected. Any thoughts on how this might be done? Javascript? And, yes, I know Amaya nicely toggles between browse/edit modes. And I know about the neat http://standardbrains.editthispage.com/ trick for IE. But I need to find a Netscape Composer solution as, at present, it's already sitting on most people's desktops locally. (Yeah - I know I ought to be able to expect users to go File -> Edit Page from Netscape the browser but I'm trying to make the create/edit page, publish page, create/edit page cycle as seamless as possible.)

Hey guys, let's say I've got a dtml method which calls 4 other methods: 2 of these method inserts data into MySQL the other 2 methods creates images using manage_addImage() to have a nice consistency I need these 4 actions to perform sucessfully or cancel the whole operation. is there a better solution than doing this: <dtml-try> <dtml-call method1> <dtml-except> some html response <dtml-else> <dtml-try> <dtml-call method2> <dtml-except> <dtml-call undo_method1> <dtml-else> <dtml-try> <dtml-call method3> <dtml-except> <dtml-call undo_method2> <dtml-call undo_method1> <dtml-else> <dtml-try> <dtml-call method4> <dtml-except> <dtml-call undo_method3> <dtml-call undo_method2> <dtml-call undo_method1> </dtml-try> </dtml-try> </dtml-try> </dtml-try> Thanks in advance!

Python Script limit in range()
by Peter Bengtsson 14 Mar '01

14 Mar '01

A simple Script (Python) of mine: Id: randomtext_pys Title: Returns a random text <params>length=500</params> [code] import string import random text='' pool = "qwertyuioplkjhgfdsazxcvbnm 1234567890 \n" for i in range(int(length)): text='%s%s'%(text,pool[random.randint(0,(len(pool)-1))]) return text [/code] When I test this script within the management interface of Python Scripts everything looks good and I can enter values of "length" like 100 to 10 000. However, when I call this script from a DTML Method like this: <dtml-var "randomtext_pys(1000)"> it throws an error at me. <dtml-var "randomgtext_pys(500)"> and <dtml-var "randomgtext_pys(999)"> works fine. Error Type: ValueError Error Value: range() too large (traceback below) So according to the traceback the error you find this: ----------- lib/python/DocumentTemplate/DT_Util.py ------------ def careful_range(md, iFirst, *args): # limited range function from Martijn Pieters RANGELIMIT = 1000 if not len(args): iStart, iEnd, iStep = 0, iFirst, 1 elif len(args) == 1: iStart, iEnd, iStep = iFirst, args[0], 1 elif len(args) == 2: iStart, iEnd, iStep = iFirst, args[0], args[1] else: raise AttributeError, 'range() requires 1-3 int arguments' if iStep == 0: raise ValueError, 'zero step for range()' iLen = int((iEnd - iStart) / iStep) if iLen < 0: iLen = 0 if iLen >= RANGELIMIT: raise ValueError, 'range() too large' return range(iStart, iEnd, iStep) ------------------------------------------------------------------- WHY is that LIMIT there? I can mod my Python Script to accomodate for the value of 1000, but I am just curious of it.
