Fishbowl proposal: HookablePUTCreation
by Tres Seaver 27 Nov '00

27 Nov '00

I have just created a fishbowl proposal for hooking the creation of new objects during HTTP/FTP PUT operations: http://dev.zope.org/Wikis/DevSite/Proposals/HookablePUTCreation Note that this proposal stems from my hack this weekend, which makes it possible to create portal content via FTP; I am confident that this is a *short* project. Please comment at the discussion page, Tres.

CVS bug
by Bill Anderson 27 Nov '00

27 Nov '00

I recently checked out a CVS version of Zope, and upon firing it up, it gives an unauthorized error on the default index_html. You know, the one that is included by default, that welcomes you to zope. After changing it, and checking to verify that view is selected, etc. it still does so. Has there been any progress on this? Just as a manner of some form of completeness, I copied the data.fs to a 2.2.2 installation, and it works fine. Bill Anderson -- E PLURIBUS LINUX

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

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
