Agh! Factory eats HTTP_REFERER!
by LEE, Kwan Soo 16 May '00

16 May '00

Hi Zopistas, I'm developing a rudimentary Web-based URL directory(sort of bookmark) managing product for the Korean Python User Group. To reduce required typing, I'm trying to utilize HTTP_REFER variable, i.e. when a member find an interesting URL, he(there is no female in PyKUG, yet :-[ ) visit the bookmarked submit page, then the interesting URL appears in the submit form. ZClass Add Form works as expected if I invoke directly. But the HTTP_REFERER REQUEST variable vanishes when Adding ZClass through ZClass_factory. Does Factory chop off some REQUEST variables? If so, why? & how? I just thought of a far more kludge workaround, but still I'll appreciate any enlightenment. thanks in advance, LEE Kwan Soo

I have a different folder per user. Making a new folder for every quarter or so for manageability sake makes sense, but it's not needed for searchability. Trust me. There is no practical limit to the number of items you have in a folder. The disk usage hit when you add an item to a folder with 30,000 objects in it is huge though. ObjectManager isn't meant for that. Also the management interface would be a bit of a problem. To manage larger folders I use a ZCatalog interface anyway. > > I have a calendar here that has folders for each "user" and displays the > > calendar of their events by having the Catalog search for the "day" on > > OK, now I have to try to understand your code (I'm new to Zope, I mean I > use it for five months but with only one hour or two per week > unfortunately) and see how I can use it.

ZODBC general sql question
by Tom Smith 16 May '00

16 May '00

I've been playing with the ZODBC stuff. It's fab..... How do I create a primary_key field with an index on it? How do I auto-increment a primary_key id field? ...are there ways to do this in agnostic SQL, without having to fiddle with the respective database. I'm using Access, but would like sometime to give mySQL a whirl without changing SQL-code (much), or getting involved with whatever Front-end each database may have. Will I have to create a table of last_ids and increment the values each time I insert a new record, or is there an easier way to do it than this? cheers tom p.s Does anyone know of a resource with lots of examples of agnostic sql queries. I pretty much get the basics but it's good to see them in action rather than have them described.

Query syntax for ZCatalog
by Curtis Matthews 16 May '00

16 May '00

I'm using ZCatalog to index a number of different documents. I want to write a brief help page for my website users on how to structure queries to help them find what they're looking for. Does such a document exist already? If so, could someone point me to it? If not, would I have to go into the source to figure it out, or is there an easier way? Thanks, Curtis Matthews

Zope 2.2.0a1: Objects cannot be owned by the superuser
by Wolfgang Strobl 16 May '00

16 May '00

I was going to try one of my apps on Zope 2.2.0a1 (win32), finding myself in a kind of catch22 situation: I can't get in at all! After installing Zope 2.2.0a1 into a fresh directory, I login under the "superuser" account in order to get to the management screen, but can't create any folder or object. I can add users to the acl_users folder. But how, pray tell, am I expected to trigger an login as a non- superuser user? Usually, I create a folder (or another object) which is restricted to some use; accessing that object triggers the authorization request, i.e. the user/pwd dialog in the browser. In short: I am required to login as a non-superuser in order to create an object, but I am required to create an object in order to login as a non- superuser. Catch22 PS: tried this with WIN2K IE5 -- o ( Wolfgang.Strobl(a)gmd.de (+49 2241) 14-2394 /\ * GMD mbH #include _`\ `_<=== Schloss Birlinghoven, <std.disclaimer> __(_)/_(_)___.-._ 53754 Sankt Augustin, Germany ________________

Suggestion for management screens
by Jeff Sasmor 16 May '00

16 May '00

I put this as a suggestion and a question as well: How do you tell what type of 'thing' a property is? Some are easy, a boolean is a checkbox, text is a field (and BTW, what's the difference between text and lines, they look identical??). But some are unremarkable: e.g.; how do you tell the difference between an int and a string if it's not obvious from the string: 336699 (as a string to be used as a bgcolor, for example) 336699 (as an integer). <suggestion> D.C., perhaps you might consider displaying the type info in addition to what's already there... </suggestion> Unless this is a newbie question and there's some real obvious answer to this that I have missed TIA, Jeff Sasmor jeff(a)sasmor.com

Anyone used Pyro (Python Remote Objects)?
by Cary O'Brien 16 May '00

16 May '00

I'm looking at a way to set up a distributed system, distributed for performance and fault-tolerance. I'm pretty sure about using Zope and Python, and I've been looking at Pyro http://www.xs4all.nl/~irmen/pyro.html To handle the remote service accesses. So... 1) Has anyone used this with Zope? It seems as if a client-side management interface would be possible, allowing pointey-clickey access to remote services. This is a bit beyond my Zope understanding at the moment. 2) Pyro uses TCP connections to exchange data. Will Zope allow multiple concurrent RPC calls (i.e. one per thread)? 3) Any other options I should look at[1]? I'm mostly interested in wrapping some business logic around the database and putting it on a different machine for performance and security reasons. -- cary [1] I know, I know. I'll go back and read the ZEO stuff today!

2.2.0A + Squishdot
by Christopher J. Kucera 16 May '00

16 May '00

1) Zope 2.2.0 Alpha seems to break Squishdot. The query function seems to have moved from Lexicon.py to UnTextIndex.py. (The code that seems to be causing the problem is in the Zope code, not the Squishdot code, which is why I'm posting it here): 2000-05-16T14:23:10 ERROR(200) Zope Couldn't import Products.Squishdot Traceback (innermost last): File /usr/local/zope/Zope-2.2.0a1-src/lib/python/OFS/Application.py, line 389, in import_products (Object: string) File /usr/local/zope/Zope-2.2.0a1-src/lib/python/Products/Squishdot/__init__.py, line 128, in ? File /usr/local/zope/Zope-2.2.0a1-src/lib/python/Products/Squishdot/Squishdot.py, line 131, in ? File /usr/local/zope/Zope-2.2.0a1-src/lib/python/SearchIndex/TextIndex.py, line 217, in ? ImportError: cannot import name query 2) (larger question) Do things like this get put in the collector, too, or is there a better place to report possible bugs about the Alpha version? Thanks! -CJ

Hello, i've created a simple image/zclass. I can instance it only as manager: which permissions i must give to a normal user to add an instance to a zclass?
