[want_to_grok_grok]

I would need more clarification ... I've been able to create and
traverse multiple containers, how does grok know where to attach
variables to  containers ?

def Sample(grok.Application, grok.Container):
     def __init__(self):
        super(Sample, self).__init__()
        self['contacts'] = ContactsContainter()

class ContactsContainter(grok.Container):
    pass

class IContact(interface.Interface):
    """Data schema for contacts"""
    surname = schema.TextLine(title=u'Surname',description=u'Contact
\'s surname',)
    name = schema.TextLine(title=u'Name', description=u'Contact\'s
name',)
    notes = schema.Text(title=u'Notes', description=u'Notes about this
contact',)

class Contact(grok.Model):
    grok.implements(IContact)
    def __init__(self, surname, name, notes):
        self.surname = surname
        self.name = name
        self.notes = notes

class AddContact(grok.AddForm):
    grok.context(ContactsContainter)
    form_fields = grok.AutoFields(IContact)

    @grok.action('Add contact')
    def add(self, **data)

in AddContact should the context be Sample ? Is it possible to get
access to Sample from the AddContact class as to have access to
functions and variables set in it ?
