portal factory for anonymous users
Deichi
the README.txt states, that "Registrant objects CANNOT use
portal_factory; if you try to do things that way, anonymous users will
not be able to register for events."
and some stuff about bugs in the permissions.
That's all nonsense. You only have to overwrite the standard
invokeFactory procedure.
I "stole" this from one of (I think) jensens' products. If found it
through a comment on plone.org somewhere, but can't find it right now.
I use this code for my own Registrant object since a while and it works
fine:
security.declarePrivate('anonymousInvokeFactory')
def anonymousInvokeFactory(self, container, type_name, id,
REQUEST=None, *args, **kw):
"""
Anonymous cannot add objects with InvokeFactory, so this is a
special
method to do it with. Must be called from other function to limit
possibillities of abuse.
"""
user = self.getWrappedOwner()
newSecurityManager(REQUEST, user)
container.invokeFactory(type_name, id, REQUEST=REQUEST, *args,
**kw)
security.declarePublic('addAnonymousParticipant')
def addAnonymousParticipant(self, fieldnames=None, REQUEST=None):
"""
Lets anonymous users add participants
"""
message = '?portal_status_message=%s'
if fieldnames is None:
fieldnames = []
kw = {}
for fieldname in fieldnames:
if fieldname in REQUEST:
if hasattr(REQUEST[fieldname],'decode'):
kw[fieldname] = REQUEST[fieldname].decode('latin-1')
else:
kw[fieldname] = REQUEST[fieldname]
# generate an id
now = self.ZopeTime().strftime('%Y%m%dZ%H%M%S')
id = 'participant.%s.%s' % (now, random.randint(1,1000000))
self.anonymousInvokeFactory(self, 'Participant', id,
REQUEST=REQUEST, **kw)
newParticipant = getattr(self, id)
# set attributes
for key, val in kw.items():
if key=='image':
newParticipant.setImage(val,val.filename)
else:
setattr(newParticipant, key, val)
# reindex in the catalog
newParticipant.reindexObject()
# Redirect back to form
absolute_url = self.absolute_url()
message = message % 'Sucessfully added participant'
REQUEST.RESPONSE.redirect('%s/thankyou%s' % (absolute_url, message)
)
That's only a way it works in this class and not all stuff in here is
necessary of course, but it should make the way clear how to implement
the factory into EventRegistration.

Have you looked at SignupSheet?

I currently don't have the time for that :(
Is it abandonded because of that? ;)
> Have you looked at SignupSheet?
Indeed. That's what I use now, but both Products would need some work
to link them together.
In fact it is a property of an event if it offers a sign up sheet or
not and which one.
