Re: [Zope] ZClass Adding Magic Needed

Perhaps I didn't give enough detail about what I'm doing. Here's a little ASCI art that may clear things up: CLASS META TYPE PROPERTIES ---------------------------------- ZClass1 (blob) -> id, displayOrder \ \ \/ ZClass2 (chunk) -> id, displayOrder, alignment, text ZClass1 is basicly a container class for a bunch of displayable subobjects. Each blob can contain a variable number of chunks, although for the purpose of creating a new blob I'm only concerned about it starting with a single chunk. Right now (if I create a number of sample blobs and chunks by hand) users can manipulate the display order of individual chunks within a blob. The can also manipulate the display order of blobs relative to one another. But now I need to give them the capacity to generate a new blob with one default chunk. This _seems_ like it should be an easy thing to do. And in fact I have no problem with creating a public add method. My problem comes when I want to give these two new objects starting values from the same form. Something like this works perfectly: <dtml-with "manage_addProduct['ChunkProduct']"> <dtml-call "chunk_blobClass_add(_.None, _, NoRedir=1)"> </dtml-with> Where I change the add method of a blob to also always also add a chunk and appropriately adjust the permession of my add method so that anybody can use it. The user will need to control the the displayOrder of the blob. It's default chunk will always have a displayOrder of 1. The user also needs to control the alignment and text of the default chunk. And note again that when both the blob and it's chunk are created they are given a random id based on ZopeTime, since I don't want my users to have to care about the id of either object. Because of this I don't need to worry about passing an id to either one of them from my form... I hope this at least manages to clear up my problem a bit. > Use a Python Script/Method to do the background heavy lifting.

The traceback for this was: It seems that you PythonScript was called without a namespace being passed. In this case, a new (essentially empty) "_" is created. It does not contain 'REQUEST'. You could try return self.artists.manage_addProduct['Artist'].Artist_add(_.None,REQUEST) Dieter

Sorry, I should have been more precise. I only had the latency, accessing the zope server from some clients. Accessing zope from the server machine was fine. So I made a (fake) entry to the hosts file for the client machine, which accesses the server and the latency was gone :) Really strange, release 2.2.4 and before ran perfect without that. But, nevertheless, thanks a lot for the hint. Bories ---- Bories v. dem Bussche clamor(a)fafalter.de

skinscript and URL traversal question
by Aaron Payne 17 Jan '01

17 Jan '01

Hi all, I'm using a zsql method in a skinscript with query ... compute ... and it mostly works. Calling the dataskin where the id is part of the query string (coupon id=977931214.694) works. For example, http://CouponSite/CouponManager/CouponAttributes?Cid=977931214.694 Where: CouponManager is a specialist 977931214.694 is the id of the coupon CouponAttributes looks up the dataskin with: <dtml-with "getItem(Cid)"> <dtml-var couponattributes> </dtml-with> Trying to access the object directly through URL traversal fails. http://CouponSite/CouponManager/977931214.694/CouponDetails Where: CouponDetails displays the coupon attributes with: <dtml-var couponattributes> It returns a not found error. The CouponManager specialist can't find the coupon 977931214.694. Any thoughts why this is so? SkinScript Trigger: WITH QUERY searchByNameCheck(self.id) COMPUTE name,username,coupon_text,categorylist,categoryheader,expirationdate,status,couponterms PythonMethod: searchByNameCheck <params>self,name<params> Cname=name result=self.searchBy_Name(name=Cname) #zsql method return result Error Type: NotFound Error Value: None Traceback (innermost last): File /usr/local/etc/Zope2d/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/etc/Zope2d/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/etc/Zope2d/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ProviderContainer) File /usr/local/etc/Zope2d/lib/python/ZPublisher/Publish.py, line 162, in publish File /usr/local/etc/Zope2d/lib/python/ZPublisher/BaseRequest.py, line 338, in traverse File /usr/local/etc/Zope2d/lib/python/Products/ZPatterns/Specialists.py, line 25, in __bobo_traverse__ (Object: ProviderContainer) NotFound: (see above) Zope version: Zope 2.2.1 (source release, python 1.5.2, linux2) System Platform: freebsd4 -thanks, Aaron

"Picture of the day" product
by Timothy Wilson 17 Jan '01

17 Jan '01

Hey everyone, I was looking at linux.com the today and I noticed their "Daily Photo." I occurred to me that that would be a fun addition to the school's page that I'm developing. My first thought would be to: * inherit from Image * add caption, date taken, etc. properties * create an archive of past photos What I'm not sure about is how to have Zope automatically display the photo for a day, then archive it. Would a boolean property of the ZClass work? Is it possible to have Zope set the property of a ZClass instance at certain time? Any thoughts on how this would be designed? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

ZMySQLDA and Win32 Zope crash
by peter bengtson 17 Jan '01

17 Jan '01

Phil and rest of the Zommunity I followed the instructions on http://www.zope.org/Members/philh/mysql which has helped me successfully twice (out of two before) on Windows NT and Windows 2000. This installation was seemless like others, and the product doesn't look broken from the Control_Panel/Products view. The only thing I've been able to do (not too bad) is to add a Z MySQL Database Connection with the proper syntax there "database root <password>". That works fine. Whenever I try to use the connection in any way, it crashes Zope! "An application error has occurred and an application error log is being generated. python.exe" ... and from the console Zope (in debug mode) looks to be still running, but from the management interface I can see that it's not (nothing happens!). William Crandall had a similar question with more details but with the same result as I. No answer to this one: http://zope.nipltd.com/public/lists/zope-archive.nsf/242bb7cc2b2c343d802568a b003585d4/f5a855d999e73c978025693600507b4e?OpenDocument I tried it on 2.2.2, failed tried to upgrade to 2.2.5 failed as well. MySQL: 3.22.34-shareware-debug (no anonymous user set up) Windows NT(4) Python 1.5.2 in Program Files but I have that other python.exe in the <zope dir>/bin ZMySQLDA 1.1.3 I used the MySQL.pyd you provided from your How-To I also used the libmySQL.dll you provided from your How-To What can be the reason for this? Is it strange Zope/ZMySQLDA behaviour or is it my MySQL? Thanks alot!, Peter
