[Zope3-Users] directlyProvides and formlib

[luis]

Hi all,

I'm having problems getting interface.directlyProvides to work...

does anyone know why the following code doesn't work (file is created, but
it doesnt provide the IMarker interface...)

###############################
# test.py
from zope import interface
from zope import schema

from zope.formlib import form
from zope.app.file.file import File


class IMarker(interface.Interface):
    """ marker test interface """
    
class IFileUpload(interface.Interface):
    """ schema for uploading files"""
    file = schema.Bytes(
        title=u"File",
        required=True)

class AddFileForm(form.AddForm):
    """ Add """
    form_fields = form.Fields(IFileUpload)
    
    def create(self, data):
        file = File(data = data['file'])

        # this is not working, or at least is not being "saved" 
        interface.directlyProvides(file, IMarker ) 
        
        return file

the registration is
