External Method and Nested ZClasses
by Chris Bruce 17 Jan '02

17 Jan '02

I have looked at the following example for adding a ZClass in an EXTERNAL METHOD from (http://www.zope.org/Members/tazzzzz/addZClasses) -------------- def addAMyZClass(self, id, REQUEST=None): """ """ # Get the actual destination object, using the this() # method, to be sure we get it in the right context.. self=self.this() # Create the new instance newob=self.Control_Panel.Products.MyProduct.MyZClass(id) newob._setId(id) # Set properties based on the contents of the Add form newob.propertysheets.Basic.manage_changeProperties(REQUEST) # Add a new Folder to the new instance newob.manage_addFolder('foobar') # Add the new instance to the target object self._setObject(id, newob) return 'OK!' ------------------ But, how do you add a nested ZClass. For instance, if MyNestedZClass was a zclass inside of MyZClass? I have tried: ... newob=self.Control_Panel.Products.MyProduct.MyZClass.MyNestedZClass(id) ... But it gives me an attribute error for MyNestedZClass. I have searched and experimented, but I can seem to get a reference to the Nested ZClass. This seems very easy in DTML, but I can't figure it out for external method. Any help is GREATLY appreciated. Thanks, Chris __________________________________________________ Do You Yahoo!?

Workflow Product
by Thomas Guettler 17 Jan '02

17 Jan '02

I am searching a workflow product. I discovered two: DCWorkflow in CMF and OpenFlow. I tried the OpenFlow some time ago and it doesn't seem to be stable. Can someone copmare DCWorkflow and OpenFlow? How stable is DCWorkflow? Can it be used without CMF, too? I am just interested in a workflow, not in skinable GUIs or dublin core. BTW, I thing the documentation about CMF should tell more facts. -- Open Source Software Solutions Thomas Guettler <guettli(a)thomas-guettler.de> http://www.thomas-guettler.de

problem with python method as ftp client
by rayprice2001 17 Jan '02

17 Jan '02

Hi, I am trying to run a python method from within zope 2.4.3 and I'm getting an error. Is is possible to have a python method act as an ftp client? The script runs just fine when I run it from command line. It appears to be failing on the "from ftplib import FTP" line. Any ideas as to what the problem may be? Code and error are below. Ray script GetCourse: ########get the file from the ftp server from ftplib import FTP DATA=FTP("www.myservermame.com") ftp.login("me","xxxxx5") print ftp.retrlines("RETR classlist.txt") ftp.close() ########## Error:

How to find out what a Class inherits and implements?
by Heimo Laukkanen 17 Jan '02

Hi all, this is more of a python question, but was wondering this while working with zope. When reading a source of a Product, is there any way of finding out easy -- what are the actual classes that it inherits and imports. -huima

How to receive the type of a property?
by Lars Heber 17 Jan '02

17 Jan '02

Hello, I'm writing an own management screen for a property sheet in one of my ZClasses. I want to iterate over all properties of that class - no problem with <dtml-in "propertysheets.Attribute.propertyIds()"> But of course, for each type the input field is a little different, so I need to differentiate between them. How can I get the type of a property? Unfortunately, the getPropertyType(id) method of the PropertySheet class is restricted to Python only. Are there any workarounds? Thanks! -- Lars Heber, mailto:Lars.Heber@t-systems.com T-Systems, debis Systemhaus GEI GmbH, Geschaeftsstelle Sachsen

inherit folder objects
by Jerry McRae 17 Jan '02

17 Jan '02

Hi Zopeople, Couldn't find anything in archives. This seems like it is possible, but I cannot get my mind around it. Anyone have any ideas (if my question makes sense)? Is there a folder structure I can set up that will allow me to inherit all the objects in another structure? Transparent & Mirrowing (Mirroring) Folders work *if you know what you are looking for*. I need to have objectIds() return ALL items in the folder AND its 'super' folder. I can inherit any single folder easily, but since this creates a deeper URL, this defeats the usability aspect. I want the users to be able to use a single name for a whole set, whether some objects in the set come from somewhere else or not. E.G. I have folder HOUSE that contains 10 folders, some of which contain other sub-folders. This will have user interfaces, so that they can see all folders and objects, add, delete, or change folders and objects, change parameters, then press the 'build-it' button in the HOUSE folder, and something happens. All objects in HOUSE are processed, and other folderish objects are also processed. No problem. Now, the user wants to create HOUSEBOAT, which inherits everything from HOUSE. I want them to be able to: 1) remove objects - delete Processes/Foundation and Materials/Cement 2) change objects - change Cost in Prereq/Permits/County 3) add objects - add Prereq/Permits/Mooring -so far, a cut/paste would work- 4) change when HOUSE changes - when Labor/Workers changes in HOUSE, it should be reflected in HOUSEBOAT. 5) allow creating TwoStoryHouseBoat, inheriting from HOUSEBOAT TIA --Jerry /\_/\ Jerry McRae \|||/ mail safely: The Bat! 1.53d (~o o~) (stuck in win98) (. .)

Trying to start
by Allen May 17 Jan '02

17 Jan '02

I have re-installed Zope 6 times trying to get this to work. I am running as ROOT, I have chown the entire directory to be root and group root. I have purged the /lib/python2.1/test directory. I get a clean install and get my admin password. I then do ./start and get the error below. I try to open http://machine:8080/manage <http://machine:8080/manage> and give it the newly created admin password... no luck, it won't take it. What am I doing wrong?
