Hi all
I have created two classes. Instances of class A are timeless and instances
of class B are different each year. Each instance of class B is associated
with an instance of class A.
So I suppose I should do something like this
class A(models.Model):
name = models.CharField(max_length=20, default = 'null')
class B(models.Model):
A = models.ForeignKey('A', on_delete=models.CASCADE, related_name =
"bs")
Now I need to declare three fields on class A that point to a different
instance of class B for current, past and next year
current_B
previous_B
next_B
I cannot find a way to declare such an association. Could you help me?
Thank you
