Hi all - Those of you who have had problems with SQL Method results in the 2.2 alpha (that's probably everyone!) may want to apply the following patch to lib/python/Shared/DC/ZRDB/Results.py. If you are tracking CVS, you can just update the file. This is the fix for the authentication problem - it will be in forthcoming 2.2 beta. *** Results.py 2000/03/10 22:32:08 1.10 --- Results.py 2000/05/23 18:57:12 1.11 *************** *** 99,104 **** --- 99,108 ---- """ _index=None + # We need to allow access to not-explicitly-protected + # individual record objects contained in the result. + __allow_access_to_unprotected_subobjects__=1 + def __init__(self,(items,data),brains=NoBrains, parent=None, zbrains=None): Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Never mind. I found the bug of mine. I now hope to get a PTK/LoginManager patch out tomorrow.

exec in zope?
by Andrew Edmondson 23 May '00

23 May '00

I'm trying to pass a keyword argument to a function (in this case Catalog), but to generate it from variables. The following doesn't work, but it illustrates my idea: <dtml-in "Catalog(_.getitem(search_in) = _.getitem(search_for))"> The obvious way to do this in python would be to use the 'exec' command - but that doesn't seem to work in zope. Is there any way to do this in zope? -Ed -- Andrew Edmondson

(Sorry it took a while to reply to this) Well, no one here is actively working on it right now - we just know we want it to happen :^) If you have something working, that would seem to be a good baseline to build on and start discussing what the zopectl script should do. I'd really like the zopistas to take the lead on this - I've started a discussion and contributed some basic requirements at: http://www.zope.org/Products/Zope/Wiki/zopectl Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Can anyone shed any light on the following? It's got me stumped... It has only happened from 1 request so far, although it triggered off the same error for all the images on the page... ?!?

ZODB3 - updated stored objects
by Thomas Weholt 23 May '00

23 May '00

Hi, I read somewhere on www.zope.org that each time you update an object stored in ZODB3 a new record will be appended. Does this mean the entire object will be stored in a new location with the updated values? If so, isn`t that kinda dumb, at least if there`s no way to override this "feature"? Anyhow, I want to store several big custom objects in ZODB. These objects can be frequently updated, and I`d like to update the previously stored object, not store the entire thing again. Can anybody clarify or give me hints on how to do this? Thomas

ZCatalog and Huge Customized Objects in ZODB
by Thomas Weholt 23 May '00

23 May '00

Is it possible to store lots of huge objects, like 2-3 MB in size each, in ZODB and catalog them for easy searching? Can I catalog special properties of custom objects and skip others? Are there any limitations to ZCatalog and the amount of stuff to index, before the speed is affected? If somebody has pointers on how to store custom python-objects in ZODB and make them ZCatalog-aware or somehow work with the ZCatalog, I`d be most grateful. Thanks. Thomas

Anyhow, I This is true with the default Zope "storage" FileStorage. It's not "dumb", because it's the feature that makes undo and versioning work. Other storages like dbmStorage and Ty Sarna's BerkeleyStorage don't work like this, and they might be more suitable for you. Of course those storages don't do undo or versioning. See lib/python/ZODB/dbmStorage.py and http://www.zope.org/Members/tsarna/BerkeleyStorage

DateTime objects's and ZCatalog
by Jason Spisak 23 May '00

23 May '00

Shane, Actually, one big thing I did notice is that when I run the DTML that calls the ZCatalog search for the external method that is stored in a Field index called 'calendar_day', I get an instance of DateTime.DateTime.DateTime for ALL of the instances that use that external method. Shouldn't they already be in the index? Why does it need to instanciate those? external method: def calendar_day(self) return int(self.calendar_date)/100000 Here's the DTML method: <dtml-var standard_html_header> <dtml-var staff_header><br> <center> <dtml-calendar mode=month> <dtml-if "mode=='month'"> <a href="<dtml-var "linkDate(date)">"> <dtml-if "_.len(Catalog(recruiter=AUTHENTICATED_USER.getUserName(), meta_types=['Interview', 'Call', 'Appointment', 'Deal'], calendar_day=_.int(date)/100000))"> <font color="FF0000"> </dtml-if> <dtml-var date fmt=dd></a> </font> <dtml-elif "mode=='day'"> <font size="+3"><b> <dtml-var date fmt=dd> </b></font> <dtml-in "Catalog(recruiter=AUTHENTICATED_USER.getUserName(), meta_types=['Interview', 'Call', 'Appointment', 'Deal'], calendar_day=_.int(date)/100000)"> <p><dtml-if "meta_type=='Call'"><dtml-with "resolve_url(getpath(data_record_id_), REQUEST)"><dtml-with aq_parent><dtml-if "meta_type=='Contact'"><dtml-with aq_parent><a href="<dtml-var BASE0>/<dtml-var url>?frame=</dtml-with><dtml-var id><dtml-else><a href="<dtml-var BASE0>/<dtml-var url></dtml-if></dtml-with>" target="_parent"></dtml-with><dtml-else><a href="<dtml-var BASE0>/<dtml-var "Catalog.getpath(data_record_id_)">"></dtml-if><font color="FF0000"><dtml-var calendar_date fmt=AMPMMinutes> : <dtml-var meta_type></font></a> </dtml-in> <form action="manage_addProduct/Staff/AppointmentClass_factory" method="post"> <center> <table> <tr> <td> <i>An Appointment is something other than an Interview or Offer, <br>or anything else in the system related to recruiting. <br>To create the appointment click "New Appoinment" <br></i> <input type="hidden" name="appointment_day" value="<dtml-var date fmt=Date>"> <input value="New Appointment" type="submit"> </td> </tr> </table> <center> </form> <dtml-elif "mode=='week'"> <a href="<dtml-var "linkDate(date)">"> <dtml-if "_.len(Catalog(recruiter=AUTHENTICATED_USER.getUserName(), meta_types=['Interview', 'Call', 'Appointment', 'Deal'], calendar_day=_.int(date)/100000))"> <font color="FF0000"> </dtml-if> <dtml-var date fmt=dd></a> </font> <dtml-in "Catalog(recruiter=AUTHENTICATED_USER.getUserName(), meta_types=['Interview', 'Call', 'Appointment', 'Deal'], calendar_day=_.int(date)/100000)"> <p><a href="<dtml-var BASE0>/<dtml-var "Catalog.getpath(data_record_id_)">"><font color="FF0000"><dtml-var meta_type></font></a> </dtml-in> </dtml-if> </dtml-calendar> </center> <br> <dtml-var staff_header> <dtml-var standard_html_footer> Is the call to compare the calendar_day to the _.int(date)/100000 creating a DateTime object for every comparison?

"Memory, all alone in the cache..."
by Jason Spisak 23 May '00

23 May '00

Shane, Well there is less blood on the floor today. It's not claiming memory as fast, but I've still had 400MB go in 3 hours. It's a slow steady decline. And the cache is slowly inclining. What is the next step? Is there a way to isolate this as a Python problem? A Zope problem? All my best, -- Jason Spisak 444(a)hiretechs.com
