-

i trying uuidfield work in python django using following model:

class ticket(models.model):     id = models.uuidfield(primary_key=true, default=uuid.uuid4, editable=false)     name = models.charfield(max_length=50)

however when try adding instance of model database returns following error: typeerror @ /tickets/ coercing unicode: need string or buffer, uuid found

the documentation of uuidfield short , doesn't me.

edit: did import uuid , here full traceback: environment:

edit 2: serializer looks this:

class ticketserializer(serializers.hyperlinkedmodelserializer):     class meta:         model = ticket         fields = ('url', 'id', 'name')

edit 3:

i found error. made mistake in model. unicode looked this:

def __unicode__(self):     return self.id

and of course not work.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
