Django syncdb，错误：一个或多个模型没有验证

Question

好的问候Django的。

我是一个新手，虽然试图确保数据库同步，我得到Error: One or more models did not validate。

任何想法如何解决它？

./manage.py syncdb --settings=settings.jacob 
Error: One or more models did not validate: 
users.userprofile: "uuid": Primary key fields cannot have null=True. 
places.category: "uuid": Primary key fields cannot have null=True. 
places.image: "uuid": Primary key fields cannot have null=True. 
places.masterplace: "uuid": Primary key fields cannot have null=True. 
places.place: "uuid": Primary key fields cannot have null=True. 

./manage.py schemamigration appname --auto --settings=settings.jacob 
Error: One or more models did not validate: 
users.userprofile: "uuid": Primary key fields cannot have null=True. 
places.category: "uuid": Primary key fields cannot have null=True. 
places.image: "uuid": Primary key fields cannot have null=True. 
places.masterplace: "uuid": Primary key fields cannot have null=True. 
places.place: "uuid": Primary key fields cannot have null=True.
