How to filter foreign key related by user?

Question

How do i filter this ?

class Base(models.Model):
    user = models.ForeignKey(User)
    base_name = models.CharField(max_length=100)

class Sub_base(models.Model):
    base = models.ForeignKey(Base)
    sub_base_name = models.CharField(max_length=100)

Now i just want to filter Sub_base based on current logged in user , how to do that ?

Answer 1

if request.user.is_authenticated(): 
   subbases = Sub_base.objects.filter(base__user=request.user)

---

if request.user.is_authenticated() , then this user is logged in, otherwise the user is Anonymous User
