[Zope3-dev] Bug Tracker

Hi,

In the bugtracker/vocabulary.py I'm getting errors like:

'PluggableAuthentication' object has no attribute 'getPrincipals'

# From src/bugtracker/vocabulary.py

class UserTerm(Persistent):
    implements(ITitledTokenizedTerm)
    def __init__(self, principal):
        # This is safe here, since we only read non-critical data
        naked = removeSecurityProxy(principal)
        self.principal = {'id': naked.id,
                          'login': naked.getLogin(),
                          'title': naked.title,
                          'description': naked.description}
        self.value = naked.id
        self.token = naked.id
        self.title = naked.title


class UserVocabulary(object):
    implements(IVocabulary, IVocabularyTokenized)
    def __init__(self, context):
        self.auth = zapi.principals()
    def __contains__(self, value):
        ids = map(lambda p: p.id, self.auth.getPrincipals(''))
        return value in ids
    def __iter__(self):
        terms = map(lambda p: UserTerm(p), self.auth.getPrincipals(''))
        return iter(terms)
    def __len__(self):
        return len(self.auth.getPrincipals(''))
    def getQuery(self):
        return None
    def getTerm(self, value):
        return UserTerm(self.auth.getPrincipal(value))
    def getTermByToken(self, token):
        return self.getTerm(token)


I'm not interested in having principals that are not in an userfolder in 
the bugtracker, so I converted it to:

class UserTerm(Persistent):

    implements(ITitledTokenizedTerm)

    def __init__(self, principal):
        # This is safe here, since we only read non-critical data
        naked = removeSecurityProxy(principal)
        self.principal = {'id': naked.id,
                          'login': naked.id,
                          'title': naked.title,
                          'description': naked.description}
        self.value = naked.id
        self.token = naked.id
        self.title = naked.title


class UserVocabulary(object):
    implements(IVocabulary, IVocabularyTokenized)
    def __init__(self, context):
        self.auth = zapi.principals()
    def __contains__(self, value):
        # let's get the keys in the userfolders
        ids = [principal for queriable in self.auth.getQueriables() for 
principal in queriable[1]]
        return value in ids
    def __iter__(self):
        terms = [ UserTerm(self.auth.getPrincipal(principal)) for 
queriable in self.auth.getQueriables() for principal in queriable[1]]
        return iter(terms)
    def __len__(self):
        return len([principal for queriable in self.auth.getQueriables() 
for principal in queriable[1]])
    def getQuery(self):
        return None
    def getTerm(self, value):
        return UserTerm(self.auth.getPrincipal(value))
    def getTermByToken(self, token):
        return self.getTerm(token)

It's a big hack, BUT at least works, and turns the bugtracker online 
again! Suggestions for a better fix?
