I'm not sure what you are trying to achieve, but you probably don't want
all of the models to use the same primary key.
You can access the primary key though via the pk or id attributes. For
instance:
Grade.objects.all().values("subjt_id", "subjt__pk", "subjt__profile_id",
"subjt__profile__pk")
However, I am not sure what you are trying to do.
Hope that helps!

Ok, thanks for replying. am quite new in Django. Am looking for a way
to use a primary key in 3 models in my django project. for instance.
The models are Profile, Subject and Grade. Want subject to link to
profile and grade to link to subject.
class Profile(models.Model): f_name = models.CharField(max_length=20)
l_name = models.CharField(max_length=20) sch_id =
models.CharField(max_length=20) class Subject(models.Model): profile =
models.ForeignKey(Profile, on_delete=models.CASCADE) maths =
models.CharField(max_length=20) english =
models.CharField(max_length=20) class Grade(models.Model): subjt =
models.ForeignKey(Subject, on_delete=models.CASCADE) score =
models.CharField(max_length=20) grad = models.CharField(max_length=20)
I don't know to archive this.
