A question about logging and Zope
by Oliver Andrich 17 Sep '99

17 Sep '99

Hi, I am nearly finished with my first inhouse Zope application - a frontend to the userdatabase that we use to manage our customers. Everything went really fine, but I like to log all actions that user do to a SQL database, cause I like to make the logfile entrys for each Userobject (in my database) viewable. can I implement a new logging facility based on the zLOG.py file or how can I implement a logging facility myself? Any hints are highly appreciated and if I am to dumb to find the info, then please help me anyway. ;-)))) Best regards, Oliver -- Oliver Andrich, RZ-Online, Schlossstrasse Str. 42, D-56068 Koblenz Telefon: +49-261-39210-40 Fax: -33 | http://rhein-zeitung.de | http://andrich.net GMC d- s++:++ a- C++ UL++++ P-- L+++ E--- W++ N+ w-- O- M-- V- PS++ PE Y+ PGP+ t 5+ X R+ tv+ b++ DI++ D- G e h- r z+

Security issues
by Steffen Ries 17 Sep '99

17 Sep '99

Hi, I had a little problem with setting the securities for a Zope Product. I was able to solve it, but I'm not sure whether it's really a 'solution' or just a 'work around'. What happened is the following: I have a Zope Product which upon creation copies a template folder (via manage_clone()) and afterwards changes the initial properties with manage_changeProperties(). The code follows the example in the Content Manager Guide. If I use this Product as 'superuser', everything is fine. But I want to delegate responsibility for the site to 'sub-managers' who don't get the superuser password, but have their own and a local role of 'Manager' in their branch of the site. After creating such an account, the new manager could create standard items like images, etc. but could not use the templates (Netscape complained with "Authorization failed. Retry?"). The problem is accessing the manage_changeProperties() method of the cloned object, not manage_clone(). In order to fix that I changed the Proxy role of the constructor method to 'Manager', after that it works as expected. My questions: - is this the right way to fix the problem? - why does a 'Manager' get no access to manage_changeProperties() of a new object, but 'superuser' does? - what are the 'security mappings' in the Product folder? (read this as: where can I find some documentation about these mappings?) What does it mean, if e.g. 'Add Folder' is mapped to '(disabled)'? tia, /steffen -- steffen(a)cyberus.ca <> Gravity is a myth -- the Earth sucks! --8<-- offending code: ... <dtml-with "manage_clone(content_folder,REQUEST['new_id'],REQUEST)"> <dtml-call "manage_changeProperties(title=REQUEST['title'])"> </dtml-with> ...

solaris build doesn't work
by Ethan Fremen 17 Sep '99

17 Sep '99

Hi, Zopes. I downloaded the solaris build for work, and when I tried to run install I got a message something on the order of: /path/to/zope/bin/python object (variable?) feewa (or something) not found (uninitialized?). (that's from memory, if it's not obvious.) Sorry for being so vague, if you need me to I can prolly track it down sometime next week. Anyway, this was after I installed python 1.5.2. I went on to compile zope from source and everything went swimmingly. Just thought I'd mention it. -- ~mindlace

Editing Zope documents with ftp - Epsilon
by Duncan Booth 17 Sep '99

17 Sep '99

My favourite editor under Windows is Epsilon which is an emacs style editor, but with a lot of support for MS-Windows styles things as well. It supports editing files via ftp (and reading by not saving files via http), and I have used it with Zope, but found it a bit inconvenient as it needed the ftp server to be on the default port. The reason I mention all this is that the new version currently in beta test supports ftp URLs on non-default ports. So I now have an easy way to edit all my Zope DTML with syntax coloured highlighting (for the HTML bits --- I haven't done a proper DTML mode yet). The downside for some people may be that it costs real money, but the beta version is available for free download for Windows, OS/2 or Linux while the beta program lasts at http://www.lugaru.com. (I have no connection whatsoever with Lugaru, except that I have been a satisfied used since version 3). -- Duncan Booth duncan(a)dales.rmplc.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure? http://dales.rmplc.co.uk/Duncan

dtml-in and batches
by Duncan Booth 17 Sep '99

17 Sep '99

I may be missing something obvious here, but if I use the in tag to iterate over a list in several batches, how can I easily work out what *all* the batches are. The user guide gives several examples using either previous- batches or next-batches to list the batches before and after, but if I want the complete list of all batches I seem to have to do a lost of work, first iterating over the first batch extracting the first and last elements, then iterating over the next batches, all of which seems unduly messy. The reason I want to do this is to build an index page with all the individual batches listed. P.S. In an earlier thread Evan Simpson wrote: >  > 'start' is supposed to be a variable name, not a number, but this > works anyway <shrug>. When using #in with 'next' or 'previous' options you have to use a variable name. -- Duncan Booth duncan(a)dales.rmplc.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure? http://dales.rmplc.co.uk/Duncan

Newbie: cant grok time parameters
by David Robson 17 Sep '99

17 Sep '99

Trying to express time in all its forms listed in Appendix A, Date-time data, of the DTML User�s Guide. For example, the Guide indicates that �pCommon� should return a string like �Mar. 1, 1997 1:45 pm�. But what�s the rest of the expression?    Don�t work. I�m reading all the docs I can find...being successful when I find explicit examples, un when not. Am I missing the mother lode of detailed examples?

ANNOUNCE: PATCH for BIG Security hole
by Jim Fulton 17 Sep '99

17 Sep '99

Earlier today, someone pointed out a large security hole in the new Zope site. After some investigation, I discovered that it was due to a bug in the handling of local roles, which are used heavily in the new Zope site. I've fixed the problem and verified that it works with the new Zope site. The new Zope site is up and running at http://www.zope.org:18200. Tomorrow we'll switch it back to port 80. Until then, the old Zope site is running on port 80. Two one-line additions were needed in the file: lib/python/AccessControl/Users.py I've checked the change in to CVS, so people using the Zope public CVS can get the fix. I'm also attaching the patched file from the 2.0.0 release. If you are running Zope 2.0.0 and using local roles, you should apply this fix by copying the attached file to lib/python/AccessControl/ in your Zope installation.
