Accessing Django OneToOneField in templates?

问题

I have the following scenario.

class A(models.Model):
    a = models.IntegerField()

class B(models.Model):
    c = models.OneToOneField(A)
    d = models.DecimalField()

In my templates, I have a list of objects A. In my template how do I access the attribute "d" from my template?

Thanks.

回答1:

class B(models.Model):
    c = models.OneToOneField(A, related_name='b')
    d = models.DecimalField()

{{ a.b.d }}
