DTML batch processing w/external method
by David Chandek-Stark 15 Apr '03

15 Apr '03

I have an external method which takes two arguments which are equivalent to the start and size attributes of dtml-in. How do I pass the batch variables to the external method? <dtml-in expr="external_method(start,size)" ...> doesn't work (NameError: global name 'start' is not defined).

Here's the external method: # from xmlrpclib import ServerProxy def directory(skip, max): s = repr(skip) m = repr(max) server_url = 'http://www.lib.duke.edu/texis/xmlrpc/directory/main.xml?skip='+s+' &maxrecs='+m server = ServerProxy(server_url) return server() # It works fine when DTML passes literals: <dtml-try> <dtml-in expr="directory(0,25)" mapping> <dtml-if sequence-start> <table> </dtml-if> <tr> <td><a href="http://www.lib.duke.edu/texis/directory/staff.html?id =&dtml-ID;"><dtml-var Person></a></td> <td><dtml-var Phone></td> </tr> <dtml-if sequence-end> <table> </dtml-if> </dtml-in> <dtml-except Fault> XML-RPC Error! </dtml-try> Thanks, David _____________________________________ David Chandek-Stark Dept. of Web Services - Perkins Library, Duke University E-mail: d.chandek.stark(a)duke.edu Voice: 919.660.5859 Fax: 919.684.2855 Dylan Reinhardt <python@dylanrein To: David Chandek-Stark <chand012(a)mc.duke.edu> hardt.com> cc: zope(a)zope.org Subject: Re: [Zope] DTML batch processing w/external method 04/14/2003 05:43 PM Please respond to python On Mon, 2003-04-14 at 14:01, David Chandek-Stark wrote: > <dtml-in expr="external_method(start,size)" ...> > > doesn't work (NameError: global name 'start' is not defined). The DTML looks OK. Care to post the external method code? Dylan

Zope 2.6.1 running under IIS on a Windows 2000 Server, with PCGI. Client browser is IE v5.50.4522.1800 running on Windows 2000 Professional. Also tried with Mozilla 1.0 under Debian. Gathering this info for you made me think about the PCGI interface, and I discovered something interesting. The redirect works great when I'm going direct to Zope port 8080 (not using PCGI). It manifests the initial request problem when using the PCGI interface. In fact, that's why Konqueror worked. I was going direct to port 8080 when I was trying Konqueror.

Thanks, Chris, for the quick reply. I tried both of your suggestions: the random query string and the setHeader statements in the ZPT. They both improved the situation in that requests after the initial one are now returned properly. However, the very first request still returns the "Problem: no session object (redirectTest)" message. By the way, instead of a response.redirect, if I return the page template directly in the script with a statement like "return container['view_session_obj.pt']()", it works perfectly. Unfortunately, I need the redirect because of the way my actual page template works.

To verify, cause the createSessionAndRedirect to generate a "random" query string like this: session = context.REQUEST.SESSION sessionObjName = 'redirectTest' session.set(sessionObjName, sessionText) return context.REQUEST.RESPONSE.redirect(context["view_session_obj.pt"].absolute_url() + '?abc=%s' % context.ZopeTime().timeTime()) This should prevent browsers from returning a cached page.

Help with session data and redirects
by Brad Powell 15 Apr '03

15 Apr '03

I have a problem where session data does not appear to be updated when the setting of the session data is followed by a response.redirect in a Python script. A browser refresh is required to get the correct data displayed. This happens on both Zope v2.5.1 and v2.6.1. It also happens with IE and Mozilla browsers; but, interestingly, it does not occur with the Konqueror browser. This led me to believe it was a browser issue, but no matter what options I try in IE, I cannot get it to work. I thought it might be an issue with the browser cache settings, but, again, no matter what I try I get the same result. I've included a test script and page template that demonstrates this problem. When I go to url "sessionCreateAndRedirect?sessionText=123", I get the message, "Problem: no session object (redirectTest)." If I then refresh the browser, I get "123" displayed, which is the correct response. Subsequent calls to the url with different values for sessionText returns the previous session value, until I do a browser refresh. Any assistance, guidance, wisdom, etc. on this matter would be greatly appreciated. ## Script (Python) "sessionCreateAndRedirect" ##parameters=sessionText ## session = context.REQUEST.SESSION sessionObjName = 'redirectTest' session.set(sessionObjName, sessionText) return context.REQUEST.RESPONSE.redirect(context["view_session_obj.pt"].absolute_url()) ## Page Template "view_session_obj.pt" ## <html> <head> <title tal:content="template/title">The title</title> </head> <body> <tal:block define="global sesObj request/SESSION/redirectTest | nothing"></tal:block> Problem: no session object (redirectTest). session obj contents </body> </html> Brad

I have a XRONDTMLMethod that makes it automatically every X hours. You could copy the code there in a DTMLMethod and call it when you like (or in a python script, too). This is the piece of code: <dtml-call "catalog.manage_catalogClear()"> <dtml-call "catalog.manage_catalogFoundItems(REQUEST,RESPONSE,URL1,URL1+'/catalog', obj_metatypes=['Folder'])"> 'catalog' is the name of the ZCatalog object, which is located in the same folder as the XRONDTMLMethod. If you want to catalog objects of type 'File', change the 'Folder' for 'File'. Igor Leturia

automate Find and Catalog
by michael.ta�ag 15 Apr '03

15 Apr '03

hi! does anybody know how i can make a link that will automatically find objects and catalog them? so instead of the users doing it manually all they have to do is click the link. Find objects of type: File with ids: <default> containing: <default> expr: <default> modified: <default> where the roles: <default> have permission: <default> If a user does it manually, he only has to select file object types. basically, everything else is the default.
