Re: [Zope3-Users] Strange ZODB error
You probably need to find out what the object is for anyone to have a chance of helping. I usually just put a pdb in the ZODB that is triggered if there's an error here, and then start poking around. Using the postmortem debug publisher might work too, but it has caused enough problems for me in the past that I dropped it, myself.

The way you attach information on a principal is to use principal annotations. BTW, the homefoler implementation (http://svn.zope.org/zope.app.homefolder/trunk/) is a great example of how to associate additional information with a principal. To use the names in the form (As a choice), i've learned they have to be in vocabulary, but how do I get these names in the vocubulary after the Principal is authenticted?

I guess it depends on what you mean by user account. One approach (apparently not the first folks think of) would be to use a separate principal for each resident, and all residents would be associated with a single shared account. It really depends on what the account represents (billing, perhaps), and whether it really mattered if you could really tell the residents apart for an account, or if the honor system is good enough. -Fred -- Fred L.

The example is not to long, however it is not trivial: uses formlib, an object in its schema, object widgets, object widget dispatcher etc. - I have therefore included the complete example. - for convenience: I have also put it online (my old university account) $ wget -nd http://user.cs.tu-berlin.de/~reuleaux/contacts.tgz $ tar xvpzf contacts.tgz $ cd contacts edit buildout.cfg as you see fit, you might for example change the eggs-directory maybe adjust the mngr user/passwd in src/contacts/app.zcml $ python bootstrap $ ./bin/buildout $ ./bin/instance start usage / steps to reproduce: go to http://localhost:8080 log in as mngr and add some contacts - that works fine now edit such a contact (say I have given it a name rx) http://localhost:8080/rx/edit and try to save it: boom! I am aware that object widgets are kind of superseeded with the advent of z3c.form - and I really want to go in that direction but for the time being my programming would be much more relaxed if I got this example working, I could really need a helping hand here, thanks. -Andreas interfaces.py from zope.interface import Interface from zope.schema import TextLine, Object class IAddr(Interface): an address. street = TextLine( title=ustreet, description=uthe street, required=False, missing_value=u'' ) city = TextLine( title=ucity, description=uthe city, required=False, missing_value=u'' ) zipcode = TextLine( title=uzip, description=uthe zip code, required=False, missing_value=u'' ) class IContact(Interface): a contact name = TextLine( title=uname, description=uthe name, required=False, missing_value=u'' ) firstname = TextLine( title=ufirstname, description=uthe firstname, required=False, missing_value=u'' ) addr=Object( title=u'address', description=u'the address', required = False, schema=IAddr) addr.py from zope.interface import implements from interfaces import IAddr from zope.schema.fieldproperty import FieldProperty from persistent import Persistent class Addr(Persistent): Eine Addr. implements(IAddr) street = FieldProperty(IAddr['street']) city = FieldProperty(IAddr['city']) zipcode = FieldProperty(IAddr['zipcode']) def __init__(self, street=u'', city=u'', zipcode=u'', titel=u'', geb=u'', fkt=u''): self.street=street self.city=city self.zipcode=zipcode contact.py from zope.interface import implements from interfaces import IContact from zope.schema.fieldproperty import FieldProperty from persistent import Persistent from zope.security.proxy import removeSecurityProxy # from zope.app.container.contained import Contained # class Contact(Contained, Persistent): class Contact(Persistent): a contact. implements(IContact) __name__ = __parent__ = None name = FieldProperty(IContact['name']) firstname=FieldProperty(IContact['firstname']) addr = FieldProperty(IContact['addr']) def __init__(self, name=u'', firstname=u'', addr=None, ): self.name=name self.firstname=firstname self.addr=addr # def __getstate__(self): # s=Persistent.__getstate__(self) #s['addr']=removeSecurityProxy(self.addr) #return s views.py from zope.formlib import form, namedtemplate from zope.app.pagetemplate.viewpagetemplatefile import ViewPageTemplateFile from interfaces import IContact from contact import

If somewhere in my code zalchemy is used, the TypeError emerges. It seems that recently there was a change to the zalchemy package (svn log): r78682 | zagy | 2007-08-08 10:53:01 +0200 (Mi, 08 Aug 2007) | 1 line using the threadlocal strategy of sqlalchemy instead of creating one engine per thread. This allows connection pooling for instance. I reverted zalchemy to an older version an all is well again. Interesting. I wonder why this happens. I'll try to reproduce. -- Christian Zagrodnick gocept gmbh co. kg · forsterstrasse 29 · 06112 halle/saale www.gocept.com · fon. +49 345 12298894 · fax. +49 345 12298891 ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
