Zope security: manager role unable to add class instances
by Darran Edmundson 10 Aug '00

10 Aug '00

Imagine a Zope-hosting ISP with a single ZODB. A user Daz signs up for webhosting and sends in his custom products and Zope tree. The ISP installs said data as follows: root Control_Panel Products dazProduct dazClass1 dazClass2 acl_users (user daz with Manager role) subroot (daz's Zope tree) acl_users (user daz with Manager role) index_html The site works fine. The problem is that daz is unable to create new instances of his classes - the add methods lack the permission to call manage_editProperties. In contrast, "superuser" *is* able to add instances. I can get around this problem my giving the constructors the proxy role of Manager, but I'd really like to understand why this is happening. Any info is much appreciated. Cheers, Darran.

RE: [Zope] Transactions
by Chris McDonough 10 Aug '00

Kapil, I don't know if you've run across this yet, but the method call: get_transaction() In Python (after you've imported the ZODB module) returns the result of the get_transaction global, which helps do some transaction-related things: get_transaction().commit() get_transaction().abort() get_transaction().note() There are also semantics for committing subtransactions, though I'm not real clear on them. I *think* you commit a subtransaction by doing: get_transaction().commit(1) See Jim's ZODB UML model at http://www.zope.org/Documentation/Developer/Models/ZODB for more info. You could probably emulate what you need to do with a combination of these commands. > -----Original Message----- > From: Kapil Thangavelu [mailto:kthangavelu@earthlink.net] > Sent: Wednesday, August 09, 2000 4:59 PM > To: zope(a)zope.org > Subject: Re: [Zope] Transactions > > > Let me a bit more specific. > > i'm developing a python product which does some fairly intensive list > processing over a long list and adds stuff to the zodb based > on that.

RE: [Zope] Reloading file objects?
by Jens Vagelpohl 10 Aug '00

10 Aug '00

a simple workaround, but one that pretty much prevents any caching anywhere, is to append the URL for this file with a changing query string, e.g. a timestamp. this is what it would look like: <untested> <a href="<dtml-var name="my_file">?x=<dtml-var expr="ZopeTime()" fmt="%H%M%S">">My File</a> </untested> jens > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On > Behalf Of Peter > Arvidsson > Sent: Thursday, August 10, 2000 07:29 > To: Gijs Reulen > Cc: Mailinglist Zope > Subject: Re: [Zope] Reloading file objects? > > > Something like that will probably work but I cant tell everyone that > visit the site to change their IE settings :/ > > Gijs Reulen skrev: > > > > Have you tried to disable the browser cache (or 'temp > internet files') ? > > > > > -----Oorspronkelijk bericht----- > > > Van: zope-admin(a)zope.org [mailto:zope-admin@zope.org]Namens Peter > > > Arvidsson > > > Verzonden: donderdag 10 augustus 2000 12:56 > > > Aan: zope(a)zope.org > > > Onderwerp: [Zope] Reloading file objects? > > > > > > > > > I have file-objects containing pdf-files.

Install problems on FreeBSD
by George Osvald 10 Aug '00

10 Aug '00

Please help! Install problems on FreeBSD I've installed ZOPE several times before on different systems (win98, NT, Linux) for testing purposes. Always logged in as 'root' I never encountered any problems. Recently I finally decided to upgrade my web-site to a ZOPE-Site and that's when the trouble started. Without the root privilege I had experienced every single problem possible. But finally I managed to build both python and ZOPE. The OS is FreeBSD 4.0-stable and I used both the binary and source package. I how ever can not start neither of them. All I get is a bunch of error messages. I also would like to use ProxyPass and ProxyPassReverse configuration. Do I use w_pcgi.py or wo_pcgi.py to build ZOPE. I think since I will not be using pcgi it should be the latter. I am including the junk I got after trying to start ZOPE. Any help would be greatly appreciated.

Multiple record input into Postgresql
by William Herring 10 Aug '00

10 Aug '00

I am new to using Zope, but have been succesfull at using a psql input wizard to generate forms to dump data to a postgresql table. However, I have a dilema. I would like to generate a form that can dump multiple inserts to a variable, say x1, into a postgresql table. However, there is an additional variable, x2 that would have to be only entered once and would be the same for every record for which a different x1 is entered. I would like the user to enter up to 50 records for x1. Looking at dtml syntax it seems the <dtml-in> should do this. Could anyone point me to any examples or provide some help?
