If I have a hierarchy of models such that:
class A(models.Model):
name = CharField(max_length=10)
class B(models.Model):
name = CharField(max_length=10)
a= ForeignKey(A)
class C(models.Model):
name = CharField(max_length=10)
b= ForeignKey(B)
If I have an instance of C, as returned by:
c = C.objects.get(pk=1)
How do I get the name of A?
I realise I can go via B, but I am hoping to be able to follow the
chain back to A from any arbitrary point in (a much longer) chain.
For example:
If this was repeated up to F in an identical manner.
If I pass a function any instance from A to F I would want to return
A.name.
I am sure there must be a simple way to get the root data, but I am
having trouble finding it.
Kind Regards
Stephen
