I believe that the "related_name" parameter to ForeignKey is the name of the set of THIS model(Student) in the foreign table(Parents). So it should be, "students", not "Parents".

Only then will a parent object refer to the set of students related to it by that name. e.g. parent.students.

This was a point of confusion for me when I read this the first time as well.
