django OneToOne reverse access
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
Solution 1:
Define a related_name to call the reverse accessor.
a = models.OneToOneField(A, related_name='foobar')
# ...
a.foobar
