Hi, I have a question, is there a way or is there a product, to create a folder in the managementscreen of zope which mapps to the normal filesystem on the server. This is very useful because sometimes i have to call cgi-scripts from zope. But i can't see in zope what scripts are in the /cgi-bin/ folder. Has anyone an idea. mfg as

syntax error
by josh on 10 May '00

10 May '00

Hello, Thanks for the useful explanations before, I now have another small problem: this produces a syntax error and I am really not sure why: <dtml-call "['parent_id'].manage_change properties ({ 'children' : children })"> The second children variable has been passed to the method by a form. parent_id is a variable that contains the name of an instance. thanks again for any help. PS if it is really bad to post newbie questions like this can you tell me, or point me somewhere more appropriate? josh oN

Hi, can someone tell me how I could change this so that it prints out 27 characters? <dtml-in "_.range(28)"> <dtml-var "_.chr(sequence-index)"> </dtml-in> Thanks for your time. josh oN

Hi, i'm working with the how-to Serve PHP/Perl within Zope. I have an external python method called mymethod. In a zope-folder called "myfolder" i add the external method mymethod. I set the SiteRootPath to myfolder. I add i SiteAccess Rule to myfolder with the id of mymethod. This means on every REQUEST of myfolder/somewhere/somewhat the mymethod should be called and executed. Right ? Now the mymethod python file is that from the how-to and every time i open myfolder the error below comes up. Who can help me please. mfg as Traceback (innermost last): File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZPublisher/Publish.py, line 169, in publish File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZODB/Transaction.py, line 237, in commit File /usr/share/zope/Zope-2.1.6-linux2-x86/lib/python/ZODB/Connection.py, line 325, in commit (Info: (('OFS.Folder', 'Folder'), '\000\000\000\000\000\000\001~', '')) UnpickleableError: (see above)

> Which does bring be back to the question of what is the relationship > between the 'nobody' user and the 'Anonymous' user. They are different names for the same thing. When you visit a (Zope) site without credentials, you are visiting as the Anonymous/nobody user. 'Anonymous User' is the name that you see in Zope UI (for example in undo logs if the AU ever does something that causes a transaction). Internally in the Zope code, this user is known as 'nobody'. To be exact, the username attribute of the nobody user is 'Anonymous User'. > Currently, if you could re-authenticate as the Annonymous user, all > would be good with the world ;-) > > Unfortunately, I don't think you can... It can be hard (esp. with Basic or Digest authentication). With cookies its not as difficult, but it would be much better if there were a way that worked for all of these.

Where has the help tab gone ?
by Hannu Krosing 10 May '00

10 May '00

Hi. Is the help tab that used to be there in v.1.x of zopes gone forever or is it just well-hidden somewhere? I mean the one that used to be leftmost in the management interface and which opens the "Z Online Help" system. Or are all my Zope2 installs broken ? Or am I supposed to keep an 1.10.3 version around to access online help ? ----------------- Hannu

Some notes - On the server side, with all the new stuff about 'Owners', I'd like to suggest that the 'Find' tab better be able to find by owner :) On the changing of ownership - could a container object get a 'recursively take ownership' tab? If you've got a bunch of people working on a site, and one leaves, it would be nice to fix that easily. Particularly since having an owner deleted is bad bad. What happens if an object is cut'n'pasted? Does the ownership change? What about if a folder is cut'n'pasted - does the ownership of everything in the folder change? It looks like trying to move or rename a user database will essentially become impossible (if any users from that user database are owners)... I'm assuming that when you talk about something being accessible to the owner of the resource, this is at run-time, not creation time? So if I change a manager's roles, this will affect their objects? hm, more thoughts to come, no doubt.

Re: Great Bridge PostgreSQL

FYI, Many of you probably have seen the blurbs about Great Bridge, a new company dedicated to promoting and supporting PostgreSQL. This looked like an opportunity to tap into a source of expert support to bring the Python / Zope interfaces for PostgreSQL up to par with the currrent revs. Below is a reply to an E-Mail I sent to Colin Orr, Great Bridge's technical contact. Later, Jerry S. >From: "colin orr" <max_orr(a)hotmail.com> >To: jerry(a)spicklemire.com >Subject: Re: Great Bridge PostgreSQL >Date: Wed, 10 May 2000 08:11:08 GMT > >Jerry, > >Thanks for your enquiry and interest.

There are plenty that don't have them turned on :^) Another problem is that javascript has a _lot_ of leeway in screwing around with cookies...
