[Zope3-Users] One single EditForm for several objects
Hi there,
I have a Problem regarding to the creation and the
editing of several objects with one single form.
I do the creation with an AddForm, which uses formlib,
the schemas IFooContainer und IFooContained and a modified createAndAdd function.
Once the form is sent correctly, it creates a FooContainer object, a
FooContained object and adds FooContained to FooContainer. Thats the way
it should be and thats the way it already works.
The actual problem is the EditForm. Basically I do
the same as above, using formlib and the two schemas. But now I get the
following traceback:

TypeError: ('Could not adapt', FooContainer object
at 0x03080E30, InterfaceClass IFooContained)
-
The error seems to occur in the following line (the
second one):
class MonolithicEditForm(form.EditForm):
form_fields = form.Fields(IFooContainer).__add__(form.FormFields(IFooContained))
That works with the AddForm, but not with the EditForm.
How can I tell the system that several of the formfields belong to the
FooContainer object and the rest belongs to the FooContained object? Is there a
way to do this?
Thanks I advance,
Arne
PS: Im working with Zope 3.3 and Python 2.4

[Zope3-Users] zope3 collector monitor list?
Hi, there was a discussion last year[1] about setting up a monitor list for the zope3 collector, but that never seemed to happen. Wouldn't that make sense? At least I think it would :-) Cheers, Sascha [1] http://mail.zope.org/pipermail/zope3-dev/2005-May/014585.html -- Lalisio GmbH www.lalisio.com Puschkinstraße 1 fon +49-(0)361/541 43 80 99084 Erfurt fax +49-(0)361/541 43 79 [EMAIL PROTECTED] ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Is it possible to catalog principal annotations and how? Sure. catalog.index_doc(obj) should do it (where obj is the principal). Then you should have an indices configured to index whichever fields you want to index. Of course, those fields should be coming from an adapter for the principal that you have to create. THe adapter would look at the principal's annotation. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

This will work if you have a key reference implementation specifically for principals. The default key reference impl. is just for persistent objects, and standard Zope 3 principals are transient, generated for the current request by the pluggable auth utility.

[Zope3-Users] Open Ofice and Zope
Hello, Here I have a starnge problem. I created a knowledge base of a certain bunch of documents(PDF, MSWORD, OO) My question is when I click on the link to that document using zope(ZMI), it prompts me to use a client side application. But I was wondering if I can use the server side open office application to open all the word and open office applications.

Displaying them is just a question of writing a view which uses a clever html converter for Openoffice-, Word-, ...-files . For word, you can use 'wv' which contains a program called wvhtml. I don't know a converter for openoffice but it's file's XML structure Should make it easy to write one. If you want to edit files server based, you'll have to write some kind of AJAX-application, which I consider *very* complicated.
