Your code does about the same as my did - it also reproduces the 20000 references to objects of the item-class. And I also don't get rid of the 20000 references. I tried it! :-( christoph

who did call index_html??
by Robert Rottermann 16 Jan '02

16 Jan '02

Is there a way to know who did call index_html ? I have a product that has a view option. If this option is used I want to have the "next" index_html to call a method on the object from which the call originated. thanks for your tips Robert

Best way to have special objects in my products produc list?
by Lennart Regebro 16 Jan '02

16 Jan '02

I'm making a product that is going to have sub products that doesn't make sense anywhere else. These subproducts should therefore not appear in normal folders. There seems to be several ways to achievie this, what do YOU think are the best way, and why? I'm still using Zope 2.3.4, and I'm subclassing a ZCatalog, and therefore using the standard ObjectManager. Any input appreciated.

Hi there, We are going to exhibit Zope at the Internet Expo that takes place beginning of February in Zurich/Switzerland. To decorate the boot I need a high quality img file of the Zope logo (it will be printed 50x50 cm). I did ask for such a file on Zope.com. However my pledge was not answered yet. I anyone of you could point me towards such a file I would be grateful. Robert

I ran into the same problem a few weeks ago. Try this code, it isn't pretty, but it has worked reliably so far. Note, this code will back off on a day to keep the month. I.e., if you want one month after January 31, it will give you February 28 (on a non-leap year) or February 29 (on a leap year): # Define the method for calculating X number of months ahead... def DateAhead(theDate, num_months=0): dateStr = str(theDate) startingYear = dateStr[0:4] startingMonth = dateStr[5:7] startingDay = dateStr[8:10] endingMonth = int(startingMonth) + num_months endingYear = int(startingYear) endingDay = int(startingDay) # Add years to correspond to the added months... while endingMonth > 12: endingYear = endingYear + 1 endingMonth = endingMonth - 12 # Check to make sure that the ending month has the requisite days... dateFound = 0 while dateFound == 0: try: newDate = DateTime(str(endingYear) + '/' + str(endingMonth) + '/' + str(endingDay)) dateFound = 1 # If you got this far, the date must be good. except: endingDay = endingDay - 1 dateFound = 0 return newDate > I'm trying to add an arbitrary number of months to a DateTime value, and > keep running into problems. > > My code looks like this: > > ----- > ## Script (Python) "NewDate" > ##bind container=container > ##bind context=context > ##bind namespace= > ##bind script=script > ##bind subpath=traverse_subpath > ##parameters=Member, Effective_Date, Months_Added > ##title= > ## > Old_Date = Member.PaidThrough > Eff_Date = DateTime(Effective_Date) > > if Eff_Date > Old_Date: > Old_Date = Eff_Date > > Month = Old_Date.month() > Day = Old_Date.day() > Year = Old_Date.year() > > NewDate = DateTime(Year,Month+int(Months_Added),Day) > > return NewDate > ----- > > The problem arises when DateTime() tries to create a new date out of values > like 2002,21,15 (reached by adding 15 months to 2002-06-15).

RE: [Zope] Unable to manage/edit Zope

It's very strange that one machine with IE5.0 works and one doesn't. Anyone else heard of something like this? As for the sluggishness, IE just gets fatter every time they rev it. But, so does Netscape for that matter. You probably need more RAM.

Date addition in a Python script
by Carlson, Christopher W. 16 Jan '02

16 Jan '02

I'm trying to add an arbitrary number of months to a DateTime value, and keep running into problems. My code looks like this: ----- ## Script (Python) "NewDate" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=Member, Effective_Date, Months_Added ##title= ## Old_Date = Member.PaidThrough Eff_Date = DateTime(Effective_Date) if Eff_Date > Old_Date: Old_Date = Eff_Date Month = Old_Date.month() Day = Old_Date.day() Year = Old_Date.year() NewDate = DateTime(Year,Month+int(Months_Added),Day) return NewDate ----- The problem arises when DateTime() tries to create a new date out of values like 2002,21,15 (reached by adding 15 months to 2002-06-15). Is there a way to coerce DateTime() to handle situations like this, or an algorithm for 'fixing' such date addition? --- Chris Carlson

automatic link-tracker/corrector
by Maik Jablonski 16 Jan '02

16 Jan '02

hello, the problem: we have many hypertexts with cross-references between them. now we want to migrate them from frontpage to zope. the question is: is there a product which can correct all the cross-reference-links in case of changing the folder-hierarchy? we don't want do edit all documents by hand... it must be a tool like "ms-frontpage"'s link-tracker-correction... updating all links in all documents in your web if you move a document or a folder? something more zopish out there??? i really wanna get rid of frontpage... so please don't suggest: use frontpage for changing the references...;-) any ideas? many thanks mjablonski.
