django OneToOne reverse access

Question

I have these simple classes

Class A(models.Model):     ...  Class Meta(models.Model):     a = models.OnetoOneField(A, primary_key=True)     width = models.IntegerField(default=100) 

but when I do

a = A() meta = Meta() a.save() meta.a = a meta.save() print a.meta.width 

i get

'A' object has no attribute 'meta' 

Why is this? Am I using OneToOne wrong? if so how can i get the correct print statement?

Thanks

Define a related_name to call the reverse accessor.

a = models.OneToOneField(A, related_name='foobar') # ... a.foobar
