The simpliest method -- Create a custom EditForm and Edit DTML method inside your ZClass. Then click your the "View" tab in your ZClass, assign a view to the EditForm (make it the first view, and preferably, remove the standard properties view as well). If you do that, when your users click on the ZClass's instance, they will be presented with your EditForm. Kam

ZClass propertysheet: Selection/Multi selection/Token - how?
by Ian Blenke 16 Oct '99

16 Oct '99

Attempting to fight my way through a simple ZClass Product, I've run up against an apparently undocumented roadblock. The task: Implement a Zope Product ZClass for an Object that is merely an input form. The input forms will be thrown into a folder with ZCatalog/ZSearch to find previously entered forms. Simply put: let the user enter a pageful of form data and store it away for later retreival in a Folder. The problem: Some of the input fields are selection dropdown lists and multiple-selection lists that represent fixed options. These options will have spaces in them (killing a :token implementation). These options will need to appended to in the future. The idea: Create TinyTables as ZClass methods to enumerate the :list of items that are needed in the selection dropdown list. The attempt: Unsuccessful. No matter what I try to do, the propertysheet shows "No Value for fieldname" - or whatever I name the TinyTable to be. The working solution: Instead of using TinyTables, I can implement DTML Methods that merely return a list of options. For example, if you put the following inside a DTML method: <dtml-return "('This is the first option','This is the second option')"> you can reference the DTML method as the source variable for the selection/multi-selection variable name. But this isn't something I want to force upon the other adminstrators of the site. Perhaps the real question is "how do I efficiently manage lists of options for forms without resorting to SQL?" - Ian C. Blenke <ian(a)blenke.com> <icblenke(a)2c2.com>

RE: [Zope] The name ZOPE
by Hung Jung Lu 16 Oct '99

Hi, I want to emphasize what others have already said. I was just trying to register some domain names. And I realized just how few 4-letters domain names were left. There are virtually all GONE! Even unpronounceable, silly names like XQZQ are taken. When you have such a simple name like ZOPE, I think you'd better truly appreciate how lucky you have been. Really, the name alone today probably worth a few million dollars. Try a few search engines, and you reach every single page related to ZOPE the software, and nothing on "zope on the rope" stuff. (Notice that searching for "Python" often gives you help on reptiles.) When you have something this precious, think twice, no, think thrice before making any change. regards, Hung Jung

Missing Properties Tab for File object
by Loren Stafford 16 Oct '99

16 Oct '99

One of my users reported that he couldn't update the properties of a File object. It seems there is no tab "Properties" on the manage_main screen for objects of type "File". I know there used to be in Zope 1. Did this get lost in Zope 2? I can't think of any way I could have made it disappear, so I'm thinking DC did it. Was it dropped on purpose? ... or by mistake? There is a workaround: just add /manage_propertiesForm to the end of the URL for the object in question, and -- voila! -- there's the missing form. -- Loren

Authorisation problem
by Roché Compaan 16 Oct '99

16 Oct '99

I created a form in Zope with which the user can easily update the product list through a simple interface. I mainly used the content manager as guidance in this effort. I run into an simple problem however. Following is the piece in the "builder" script that clones an existing folder <dtml-with "manage_clone(MyFolderName,REQUEST['id'],REQUEST)"> <dtml-comment> <dtml-call "manage_changeProperties( title=REQUEST['title'], Code=REQUEST['Code'], Material=REQUEST['Material'],)"> </dtml-comment> <dtml-call "thumbnail.manage_upload(REQUEST['thumbnail'])"> </dtml-with> <dtml-call "RESPONSE.redirect(DestinationURL()+'manage_main@update_menu=1')"> When I view the "designer" and submit my changes from the Designer form i get an authentication error. Zope says that i am not authorized to "manage_changeProperties". I've checked my id's in my designer form and they match the id's used in the builder script. I am also logged in as a user with manager and owner roles and have no problem to change properties of folders in Zope itself. What could this be? Help appreciated. Roché Compaan

"include path" for DTML files
by Andreas Jung 16 Oct '99

16 Oct '99

Python functions (via external method) can open DTML templates (DocumentTemplate.HTMLFile). Where must I put the template files or must I access the template files with full path ? When I call DTML methods within such a external template file that are setup with the management screen from Zope - how can I use these methods ?

It is a very good idea. With xml-rpc, you can talk to separate processes on the same machine or on another. There are xml-rpc servers or clients in at least six languages so far. Since you have to use SOME format for interprocess communication, why not this one? Or SOAP, it probably doesn't matter much which one. Basically, if you want to operate on a number of platforms, you will do IPC using sockets, http, or (getting complicated) CORBA, etc. Most of the more complex systems are going to be built on sockets anyway. Why roll your own implementation using http or basic sockets when it has been done already? And you need SOME format for the messages, so why not an xml-based format? xml-rpc or SOAP ought to be excellent.
