Re: [Zope] ZCatalog in python (getting closer)
by ed colmar 15 Jun '00

I am getting closer to having a working catalog. Thanks everyone, all your hints have been really helpful. The catalog is automatically created when I add a new instance of my class to a folder My sub-classes now inherit: (CatalogAware, Persistent, Implicit, SimpleItem) It was the SimpleItem combined with the code used (in squishdot) to add an item that was preventing the catalog from finding it. When I changed it to: ob=PromoterPost(id,title) ob.id = id ob.title = title self._setObject(id,ob) It can now be found by the catalog when I manually update it in the management screen. It also now exists in the zope management screens, which is forcing me into better object management. =P Still, the catalog does not automatically update when a new object is added. can someone explain where the index_object() call should be? In my case it should be in the PromoterPost.__init__ method correct? It does not belong in my base class' call that creates the object right? Thanks again! -ed-

Hi, I would like to continue to program in python and zope ( don't make me go back to C/C++, please ). Does anyone have some short term contract work for me. I will be happy to send my resume in response to this email. Regards, Luis.

The right way to sum fields
by icottee＠bluefountain.com 15 Jun '00

15 Jun '00

I have a folder with a set of timesheets in it. If I create a method to sum a field called I_TimeTaken is this the correct syntax? --- <dtml-in "PARENTS[0].objectValues(['TimeSheet'])" size=1> <dtml-var total-I_TimeTaken> </dtml-in> --- To explain, this works but I'm interested to know if this is the right way. Specifically because I am now trying to write another routine which totals not just the current folder but the contents of any sub folders below and am running into problems (i.e. I can't do it). If the basic step is wrong I'd like to know before I use it in other places. Haven't managed to find anything in the archives but I think I may be suffering from docs overload. Many thanks for any help Ian Cottee (knee deep in Zope and way out of time)

Version Paradox
by Baker, Dennis [sjmr] 14 Jun '00

14 Jun '00

Help !! I've inadvertently created a version paradox. I created a version and joined it, then I realized that I did a stupid naming mistake I tried to UNDO the creation of the version. It allowed me to undo the creation of the version, however I was in the version at the time, and now I am stuck in the version and cannot get out. I cannot create a version of the same name and delete it either. I am stuck. HELP !! How can I exit a version that doesn't exist?

sequence-item as a method argument
by Fabio Akita 14 Jun '00

14 Jun '00

Hello again I´m still testing the usability and reliability of Zope. To accomplish this goal I am developing a very very simple shopping cart. But I got troubled by something aparently simple. This is the code: <dtml-in "SESSION['cartItems']"> <dtml-in "sqlSearchProduct(productID=sequence-item)"> <tr><td><dtml-var productName></td><td><dtml-var price></td></tr> </dtml-in> </dtml-in> SESSION['cartItems'] is an array created in another DTML document using the well known SQLSession product. Here I am retrieving the itens of this array and passing it to a ZSQL method to get the selected items. The sqlSearchProduct, alone, works well. If I substitute the inner <dtml-in "sql...> for a simple <dtml-var sequence-item> the block works fine, otherwise it gives me the following error: Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: sequence Anyone knows what is going on? I think this must be a simple thing. Thanks []´s Fabio Akita - Developer F/Nazca S&S / Adversiting akita(a)fnazca.com.br

Worldpilot and imap problem
by Deryk Barker 14 Jun '00

14 Jun '00

Looking through the archives I couldn't find anything which semed quite relevant, so: I'm currently running Linux mandrake 7.02 and have enabled the IMAP (4.7-7) server. I can read/write mail via netscape using imap, so I presume the setup is OK. (Although i can't quite get pine to talk to it, maybe something isn't quite right). Unfortunately, whenever I log onto worldpilot (and yes I have edited the DOMAIN.py file) the hourglass appears, presumably while attempting to fetch my mail and top shows me a python process running as zope, chewing up anything up to 80-90% of the CPU. All that seems to work is restarting zope. Trimming the contents of my mailbox down to just 6 messages didn't seem to make any difference. Anyone shed any light? Oh yes, I have applied the imap.py.diff patch to the python library. -- |Deryk Barker, Computer Science Dept. | Music does not have to be understood| |Camosun College, Victoria, BC, Canada| It has to be listened to. | |email: dbarker(a)camosun.bc.ca | | |phone: +1 250 370 4452 | Hermann Scherchen. |

pcgi.pid question?
by kwan 14 Jun '00

14 Jun '00

These couple days, I first set up a test mechine to test Zope with IIS through pcgi. On this test mechine, things work as I expect. However, when I move to the main server and go through exactly the same setup step. Things become strange. I got an error said counld not lock the database file. I check as much things as I can think of. and I found that.. when I start up the Zope on the main server. under var/ the z2.pid and pcgi.pid is the same. It make sense to me since they need to access the same database file. However right after I try on brower with http://localhost/scripts/zope.pcgi, beside the above error message, I found that the pcgi.pid got changed. Checking my test mechine, however, no matter what link I click and try, pcgi.pid still remain the same as z2.pid. What's wrong with these? pcgi.pid suppose to be the same as z2.pid isn't it? So what makes the pcgi.pid got changed? Kwan
