Objects that are properties
by Roch'e Compaan 27 Nov '00

I have a Customer and Address ZClasses based on Dataskin as well as a CustomerManager specialist. The Customer ZClass has a external method setAddress: def setAddress(self, Address) self.Address = Address CustomerManager has a defaultRack and addressRack. The methods that adds the instance contains this: <dtml-let newCustomer="newItem(name)"> <dtml-call "newCustomer.propertysheets.Basic.manage_changeProperties(test=test)"> <dtml-let address="addressRack.newItem(id)"> <dtml-call "address.propertysheets.basic.manage_changeProperties(test=test)"> <dtml-call "newCustomer.setAddress(address)"> </dtml-let> </dtml-let> and it seems to work fine. Then to retrieve the Customer addresses I call: <addressRack.getPersistentItemIDs()"> but there seems to be a problem with permissions because Zope prompts me for username and password although i'm already working in the management interface.

Hi, i found some Errors in my Help System. If i click on the Help Button of the root folder a new Browser Windows was opened, in the left Frame was the Help Tree and in the right Frame occurs the following error.

Why do I need to import the database module? Couldn't I just try to locate/create a DA when my class is instantiated? Would it be poor design to create a DA connection as an attribute of the class? Or would it be perferd to create it in the __init__ as a instance attribute? Thanks, Johan

SQL-Methods Through-the-FileSystem
by Johan Carlsson 26 Nov '00

26 Nov '00

Hi all, Does anybody have a good suggestion how to develope SQL Method ftfs (through the filesystem) rather than ttw. Perferably in someway similare to the HTMLFile way to include DTML methods in Zope classes. Regards, Johan (One problem I recently discovered was the fact that SQl methods makes "hardlinks" to SQL connection when changed. So if I move the SQL connection to some other place in the aq-path I need to update the methods. This make it hard because the SQL method seems to point to the right connection but it doesn't, in other words been very confusing for users.) torped johan carlsson birkagatan 9 113 36 stockholm johanc(a)torped.se www.torped.se voice +46-(0)-8-32 31 23 mobil +46-(0)-70-558 25 24 workshop västmannagatan 67

More ZPatterns confusion
by bentzion＠bellatlantic.net 26 Nov '00

26 Nov '00

I am trying to add a ZClass with a DataSkin Property sheet to a Virtual Rack. So I call the following: <dtml-let ni="newItem(key=REQUEST['key'])" props="ni.propertysheets.get('Basic')"> <dtml-call "props.manage_changeProperties(REQUEST.form)"> </dtml-let> I assume this should call ADDED and CHANGE trigger's to place data in my SQL Database. Unfortunately this is not happening. The ADDED trigger is doing the initial creation, but the changeProperties is not effecting the right changes. It seems that the CHANGE trigger is not getting called. Is there something else I should be doing? Thanks for all the help

Help System Menu patch
by Bill Anderson 25 Nov '00

25 Nov '00

After working with the Zope help System a bit, I got very annoyed that there was no consistent ordering to the tree. For example, you could repeatedly click the contents tab link, and watch it reorganize itsself. Attached is a patch that sorts everything by id. Why id? Because then I can make my help menu item id's a numeric sequence, and put the topics in a specific order. Example: Membership Overview Membership Conventions Rather than the order being random. Attached is the patch. patch from the Zope root directory. Once applied, you *don't* need to restart zope to see the change.
