accessing PARENTS from python???
by Kevin Howe 13 Aug '00

13 Aug '00

I am trying to access the PARENT of an object in a python class of mine. I want to use the absolute_url() of the parent in a variable. I though it could be done the following way, but got an error: parent=self.PARENTS[0] aurl = parent.absolute_url() I then tried using REQUEST. It works, but doesn't give the correct information. Instead of giving me the parent of the current object(self), it gives the parent of the DTML page in which the object was called. parent=self.REQUEST.PARENTS[0] aurl = parent.absolute_url() How do you resolve the PARENT object of an object?

Help with installing PoPy & ZPoPyDA
by ed colmar 13 Aug '00

13 Aug '00

Hi, I downloaded the current versions of ZPoPyDA, and PoPy from www.mixadlive.com, and I cannot figure out how to execute the installation. This must be a simple problem, but I would appreciate any help. In the README.in it instructs to untar, then ./configure. I /should/ CD first right? In either case, there is no success. I see a configure.in but no configure. Here is a copy of the ZPoPyDA folder, and a sample of command line errors. Please give me some clues!

Zope on Linux, Oracle on another machine (Solaris) what to do?
by Chris Beaumont 13 Aug '00

13 Aug '00

Hello, Newbie question here... Thank you for any and all help... The subject line says it all.. What's the best way to connect an instance of Zope running on a Linux box to an instance of Oracle 7.3 running on a Solaris box in the same subnet... As far as I can tell, the OracleDA seems designed to connect an instance of Zope and an instance of Oracle running on the same machine.. We don't want to do that because then we would effectively have to buy Oracle twice.. (we already have the 7.3 server up and running..) Am I wrong? I am willing to go through the whole Oracle install on this machine, to get the libraries, but I need to know that I'm not barking up the wrong tree.. Also, are there any other decent alternatives? ODBC? ???? Thank you! Chris cbeaumon(a)msri.org

Re: [Zope] ZCatalog attachments?

Someone else already told you, that you must create a parameterless method (it need not necessary be named "PrincipiaSearchSource") that returns the files content. You may not need to keep the rendered version around but may be able to extract the plain text on demand. I think, there is a "word.dll" that provides access to MS Word from applications. Alternatively, you could control Word via COM. Dieter

RESPONSE.write() slow
by Philipp Auersperg 13 Aug '00

13 Aug '00

I want to be able to download dynamic content (coming from a relational database) via Zope as a file. I do this by calling RESPONSE.write() which works fine but it is very slow When I download a greater package with an External method (on the bottom of the mail), I just get downloads of 3 to 12 KB/s in my LAN and even locally on the same machine. Also the thread sending the data uses >90% CPU. Can anybody tell me why it is so slow or how I can speed that up? I am using a standalone Zope 2.2.0 with standard ZServer Thanks in advance Philipp Auersperg ---------------------------- def streamTest(self,RESPONSE): RESPONSE.setHeader('Content-Type','text/richtext') i=0 while i< 100000: RESPONSE.write('hallo') i=i+1 RESPONSE.close()

Broken product instances when using SiteAccess
by Helge Tesdal 12 Aug '00

12 Aug '00

We have set up a site using SiteAccess. The site itself works just fine, but when moving Data.fs to other machines the instances of our products appear broken. There is no problem adding new instances. Currently we're running Zope 2.1.6, and will probably continue to do so unless this is fixed... We have copied the whole zope directory from our main site, including all installed Products, Extensions and so on. Could it be that Zope is looking for the product in the wrong places? We had SiteAccess running when the instances were added, and but have to turn it off when used on other machines. The rewriterule is included below. Any suggestions on how to make this work again? Is it possible to get some more debug info from Zope on where the instance wants the product to reside? Our rewriterule: ========================================== <dtml-call expr="REQUEST.setURL(base='http://toplevel.domain')"> <dtml-let path="REQUEST.path"> <dtml-if path> <dtml-comment> There is a path </dtml-comment> <dtml-if expr="path[-1]=='Z'"> <dtml-comment> '/Z/...' explicitly forbids redirection to 'artists' </dtml-comment> <dtml-call expr="path.pop()"> <dtml-call expr="REQUEST.setURL(path='Z')"> <dtml-elif expr="path[-1] in objectIds()"> <dtml-comment> Don't redirect existing objects </dtml-comment> <dtml-else> <dtml-comment> Everything else goes to 'artists' </dtml-comment> <dtml-call expr="path.append('artists')"> <dtml-call expr="REQUEST.set('SiteRootPATH', '/')"> </dtml-if> </dtml-if> </dtml-let> ============================================== Thanks in advance -- Helge Tesdal tesdal(a)v160b.studby.ntnu.no

Make a Python Products Add list show only certain meta types?
by Kevin Howe 12 Aug '00

12 Aug '00

I have a custom Python class (Container) which uses Folder as it's base class. I also have a custom Python class (AnObject). I want it so that when you view a Container object, "AnObject" will be the only meta_type available to be added in the Add List. The problem is that since Container inherits from Folder, the Add List makes all object types available to be added. Is there any way to tell a class to show only certain meta_types? Kevin
