Ah, that's nice and easy. Did not solve the permission problems, though. I
found out that the list object, which I defined the Lists() schema for, is
not a python list, instead it's a sqlalchemy.orm.attributes.InstrumentedList.
Therefore it seems I have to set the permissions on this object, tried it
like that:
class class=sqlalchemy.orm.attributes.InstrumentedList
require
permission=zope.View
attributes=__iter__ __getitem__
/
/class
The permission problems are gone now, but I have still some object nesting
problems with formlib. Here's what I have:
I have an object Kunde, which 1:1 relates to a Fp object. That Fp object
relates 1:n to an Email object. I defined interfaces for all of these
objects and configured them. The browser code looks now like this:
fp_widget =CustomWidgetFactory(ObjectWidget,Fp)
email_widget = CustomWidgetFactory(ObjectWidget,Email)
emails_widget = CustomWidgetFactory(ListSequenceWidget,
subwidget=email_widget)
class EditKunde(form.Form):
form_fields = form.Fields(IKunde)
form_fields['fp'].custom_widget = fp_widget
# so far, this works, the Fp object is displayed.
# Now I need to apply the custom widget to the fp.emails list object
form_fields['fp'].emails.custom_widget = emails_widget
# Hmmm, this has no effect, I receive a ComponentLookupError:
ComponentLookupError: ((zope.schema._field.Object object at 0x31e9910,
zc.resourcelibrary.publication.Request instance
URL=http://localhost:8080/act/managekunde/index.html), InterfaceClass
zope.app.form.interfaces.IInputWidget, u'')
Moreover it would be nice if I could omit some attributes of the sub-objects -
do you know if there's some way to do that? E.g. something
like form_fields.omit('fp.xyz'), or even more something
like form_fields.omit('fp.emails.xyz')?
Best Regards,
Hermann

wheel = schema.Object(schema=IWheel)
or even better:
wheel = List(min_length=4, max_length=4,
value_type = ??? of type IWheel???)
value_type=schema.Object(schema=IWheel)
What would be really great now is if formlib could handle this and
would automatically set up the needed widgets.
Not sure what it does; I think you'd need to write some custom reference
widget type thing; you can't fill in a wheel, really. :) Where would
the Wheel objects come from?
This tutorial will be enough to get you started with a custom widget for
your List-Object field.

Ah, that's very nice, thanks!
Tried it out and it seems to work for Objects() in the schema. However, for
Lists(value_type=Object()), I get permission problems:
ForbiddenAttribute: ('__getitem__', [zbsp.fp.Email object at 0x31eed90])
This happens whenever I try to access the list in any way (e.g. mylist[0] or
for i in mylist...). So it seems, I have to declare permissions for this
list - but how? For the generic Python list object?
My permissions are declared like this:
class class=.fp.MyObj
require
permission=zope.View
interface=.interfaces.IMyObj
/
require
permission=zope.ManageContent
set_schema=.interfaces.IMyObj
/
/class
I thought this would suffice?
Best Regards,
Hermann

There is also a Poll example somewhere in the ++apidoc++ which uses the Object schema field Christophe Sascha Ottolski a écrit : Am Donnerstag 19 April 2007 schrieb Hermann Himmelbauer: Tried it out and it seems to work for Objects() in the schema.

[Zope3-Users] Interfaces in Schemas
Hi, I wonder if it's possible to define attributes in a schema that reference other interfaces. For instance, I have a schema for a car and another one for a wheel and what I want to do is something like that: class IWheel(Interface): type = TextLine() class ICar(Interface): model = TextLine() wheel = ??? of type IWheel ??? or even better: wheel = List(min_length=4, max_length=4, value_type = ??? of type IWheel???) What would be really great now is if formlib could handle this and would automatically set up the needed widgets. Is this possible in some way? I found the field types Object and InterfaceField, maybe they are of this kind and do what I need?
