The easiest way to do this is to have a query of all students that has that
parent.
Add Something like this to your parent detail views,
students = Students.objects.filter(parent__id = pk)
context["students"] = students
Your Template should be
{% for student in students %}
{{student.std_matricule}}
{% endfor %}
