Hi!
I'm trying to use the dublincore subjects property with a slight
modification. Originally it uses TextLine
but i want it to use my home made "Word" schema field type (behaves
like TextLine but with no spaces)
class IWordSubjects(IDCExtended):
subjects = Tuple(
title = _(u'Words'),
description = _(u"A list of words describing the object"),
value_type = Word(title=u'Word'),
max_length=10,
)
Is this possible of doing? Just inheriting from IDCExtended and
overriding subjects...
This was added to my addform:
form_fields = Fields(IItem).omit('__parent__', '__name__') +\
Fields(IWordSubjects).select('subjects')
The adding view looks as expected and it complains when word is not a
word, and i cannot add more
than 10 subjectwords, that's all good. But as soon as all fields are
valid and it tries to create the object it fails:
File "/home/mset/Zope-3.3.1/testinstance/lib/python/foo/browser/
item.py", line 39, in create
applyChanges(job, self.form_fields, data)
File "/home/mset/Zope-3.3.1/lib/python/zope/formlib/form.py", line
521, in applyChanges
adapter = interface(context)
TypeError: ('Could not adapt', <foo.item.Item object at 0x3d32130>,
<InterfaceClass foo.interfaces.IWordSubjects>)
Seems to be some more things i need to do in addform maybe?
Here's my create function in the addform:
def create(self, data):
item = createObject('foo.Item')
applyChanges(item, self.form_fields, data)
return item
Any ideas? I'm not sure my way of doing this is even possible, maybe
there's some other very simple way?
thanks in advance
