RE: [Zope] passing :records on in a hidden field

I have passed data from one form to another using REQUEST. I collect the data from one form, with a python script as the action. The script "does stuff", and in my case, puts a list together, which I then pass to a dtml method for display. >From the script I do: context.REQUEST.set('work',work_orders_dict.keys()) return context.trace_back(context, context.REQUEST) Where trace_back is my dtml method. You can then directly access your list from the dtml_method: <dtml-in work> <dtml-var sequence-item> </dtml-in> or something similar. In your case you may be able to collect data in form 1, send it to a python script, from the script pass your object into request and call form2. Then have form 2 collect more info, send that to a script, put both objects into request, and finally have both objects available for form 3. I have never tried this mind you :) Scott -----Original Message----- From: Erik Myllymaki [mailto:erik.myllymaki@starpointe.ca] Sent: Wednesday, May 14, 2003 1:24 PM To: zope(a)zope.org Subject: [Zope] passing :records on in a hidden field I am collecting form data in a :records object: <form action="page2"> <input type=text name="stuff.name:records:string" value="" > <input type=text name="stuff.snumber:records:int" value="" > <input type="submit" value="Submit"> </form> On page2, I have another form that I am collecting data in, and would then like to pass both records objects on to page3, but a simple <input type="hidden" name=stuff value=<dtml-var stuff> > doesn't work (it passes a string that represents the records).

Solaris, Multiple Processors and ZEO?
by Steve McMahon 14 May '03

14 May '03

Has anyone attempted to improve Zope performance on multi-processor Solaris by implementing ZEO on a single machine in order to get a division of labor between processors? I'm wondering if it might be a partial solution to the documented Zope performance problem on this platform. -- ______________________________________________________ Steve McMahon Reid-McMahon, LLC steve(a)reidmcmahon.com steve(a)dcn.org

First of all, even using sleep(), the function that started the thread will not return until the thread finishes. If it starts, say, five threads, those five threads will go off and do their work but the caller will not return until all five threads do. Second, you cannot stop a thread before it wants to quit. So if you want it to quit, you have to arange for it to check some kind of a signal somewhere to tell it to do so. But if the thread is waiting on a slow socket, it cannot do any such checking because sockets are synchronous (although there is an asynchronous socket library out there, I believe that Zope does not use it - hope someone can correct me on that). So using threads effectively is harder than it might seem. Cheers, Tom P

RE:Newbie: creating objects programmatically
by Richard Jennings 14 May '03

14 May '03

Thanks to Dmitry and Maik, it works fine. So now I need to set the new ZTP contents to those of a model ZPT. Following Dmitry's advice, I read the ZPT source and figured I could do the following: instance.manage_addProduct['PageTemplates'].manage_addPageTemplate('index_html') instance['index_html'].write(instance.memberIndex.document_src(self)) but no, I get: Error Type: Unauthorized Error Value: You are not allowed to access document_src in this context I am logged in as 'manager'. I have tried: instance['index_html'].write(str(instance.memberIndex)) where memberIndex is a regular file and this works fine, but I want to use a model ZPT. Guidance needed, please!

Problem with send in ZClass
by Jamie White 14 May '03

14 May '03

I still need help with this I built a ZClass and I want to send an email if a certain property is missing, the script I am using to try to do this looks like this # Send an Email if draft == None: body="Content Provider " + AUTHENTICATED_USER.getUserName() + " has completed work on. Please review for publishing" context.MailHost.send(body, mto="jamie(a)brobus.net", mfrom="zope(a)brobus.net", subject="Content Done", encode=None) return body else: return "No Message" It works when I test it alone, but for some reason when it is run from the zclass zope says: Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access send in this context I tried changing the proxy role on the script to manager but that didn't help.

multi-column sort with ZCatalog
by Mark Nenadov 14 May '03

14 May '03

Hello all, I have a simple ZCatalog query with a sort_on and sort_order being passed to it. Is there any way I can do the sort on multiple columns? This seems like an important feature. I've heard that is not possible, but I'm wondering if I am just missing something/getting wrong info. I'm already looking into the Generic Sort External Method, but I'm wondering if there is some other way to do this? Thanks, ~Mark
