[Python-Dev] New to python, let me know if i should be posting somewhere else

2008年8月05日 08:20:40 -0700

Hi,
I am new to Python, so this question that is probably blindingly obvious to
you all.
If I have 2 classes that references each other (a circular reference of some
sort) 
and both class are defined in the single file in the order shown. 
class Resume(db.Model):
 file_data = db.BlobProperty()
 candidate = db.ReferenceProperty(Candidate)
class Candidate(db.Model):
 first_name = db.StringProperty()
 last_name = db.StringProperty()
 latest_resume = db.ReferenceProperty(Resume)
the Resume class does not know about the Candidate class as this 
module is imported, so it throws a error. Is there any way to get around
this problem?
