getPhysicalPath?
by Andy McKay 20 Mar '01

20 Mar '01

getPhysicalPath returns the physical path to an object ignoring how I got there through Acquistion. There are a bunch of variables in the REQUEST that tell me how I got to an object, but we have an object that is messing around with traversal, so the REQUEST variables arent ideal. Is there a simple method like getAcquistionPath() that tells me how I was required without having to do some sub optimal REQUEST variable hacking / string matching? Thanks. -- Andy McKay.

ZPatterns: getItem returns None
by Roch'e Compaan 20 Mar '01

20 Mar '01

I think I've read everything on the mailing lists on this issue, but have found no joy. I have a ZClass derived dataskin called AllotmentArea matching a table with the same name in my SQL RDBMS. I have a Specialist called AllotmentAreas with storage set to the AllotmentArea ZClass and load attribute set to "AllotmentArea_ID" and this property does not exist on the ZClass propertysheet. When I call getItem(<existing_id>) on the specialist, it returns None. SkinScript for retrieval: WITH QUERY sqlGetAllotmentArea(AllotmentArea_ID = self.id) COMPUTE AllotmentArea_ID, AreaName, AreaCode Note: The Proxy Role for the SkinScript is set to Manager. sqlGetAllotmentArea: Select * from AllotmentArea where AllotmentArea_ID = <dtml-sqlvar AllotmentArea_ID type=string> Roché

Starting a new process
by Christian Ellguth 19 Mar '01

19 Mar '01

Hi, I have a lengthy operation in an external method. I takes up to 2 minutes. How do I prevent the browser from timing out? At the moment I am creating a new process by calling "os.fork()" and have that operation done in that new process. At the end I call "sys.exit(0)". This worked fine with Zope 2.2.4, but Zope 2.3 gives me an error message when calling sys.exit . But sys.exit is the only way to end the child-process. Can anybody tell me what's the best way to handle a lengthy operation in an external method? Thanks Christian ____________________________________________ Christian Ellguth Rebenring 64 App. 04-05-22 38106 Braunschweig Tel.: 05 31 - 3 88 40 78 Mobil: 01 77 - 2 39 20 52 e-mail: christian(a)ellguth.de ICQ#: 41965033

call method of ancestor of ZClass
by Tim McLaughlin 19 Mar '01

19 Mar '01

Anyone know how I could call the manage_afterAdd method of ZObjectManager from a python method which is overriding the method in a ZClass. Maybe something like this (but this doesn't work. manage_afterAdd(item, container): context.ZObjectManager.manage_afterAdd(item,container) do_something_else() TIA, Tim McLaughlin

PATH_INFO reliable?
by Danny William Adair 19 Mar '01

19 Mar '01

I want to strip off the SERVER_URL of an absolute url (which I have as a string) without doing string manipulations. Is there some built-in function to do this? So what I'm looking for is actual the reverse of absolute_url. The request variable PATH_INFO looks very good, but I don't know whether this is _always_ created. Thx in advance, Danny P.S.: Maybe I just got something completely wrong here. Help!

INSTANCE_HOME vs. SOFTWARE_HOME
by Morten W. Petersen 19 Mar '01

19 Mar '01

Hi guys, some people have asked me to use INSTANCE_HOME instead of SOFTWARE_HOME, which breaks their products on debian distros. Now, I'm not sure that won't break other systems if I change it; anyone care to share? Thanks, Morten

As a bonus, can I also get > __init__.py files in each module directory to be executed? You can manipulate (extend) "sys.path" in your (top level) "__init__.py" file. Python starts its package/module lookup from the elements in "sys.path". However, I doubt very much, that you should do this! You will lose the namespace isolation provided by packages. Dieter

iso_week for Zope's DateTime
by Steve Alexander 18 Mar '01

18 Mar '01

The Collector doesn't seem to be working at the moment, so I'm posting this here. I've written a small test for my iso_week function. You can download it, plus some test data, plus the script to create the test data here: http://www.cat-box.net/steve/zope_iso_week.tar (700k) You'll need to install mxDateTime if you want to make your own test data. You'll need bzip2 if you want to use the supplied test data. The function passes the test for all dates from 1600-01-01 to 2585-08-23. I've submitted it (with the date argument renamed self) to the Collector as a feature patch to DateTime.py. if you want to keep the standard DateTime.py, you can use it as PythonScript in Zope easily enough. ---- def iso_week(date): doy=date.dayOfYear() dow=(date.dow()-1)%7 y=date.year() thurs_this_week=doy+(3-dow) is_leap=y%4==0 and (y%100!=0 or y%400==0) if thurs_this_week>(is_leap and 366 or 365): week=1 if dow<8: y=y+1 else: mon_this_week=doy-dow day_year_begins=(dow-doy+1)%7 day_of_4_jan=(day_year_begins+3)%7 monday_of_first_week=4-day_of_4_jan week=(mon_this_week-monday_of_first_week)/7+1 if week==0: y=y-1 is_last_leap=y%4==0 and (y%100!=0 or y%400==0) if day_year_begins==4 or (day_year_begins==5 and is_last_leap): week=53 else: week=52 return y,week,dow+1 ---- -- Steve Alexander Software Engineer Cat-Box limited
