In my model, I ahave a Student and Parent models. A prent can have one or
more students.
I want to list all the student in the parent page, but it is not showing.
Please see here my code.

View
def parentsDetails(request, pk):
parentObj = Parents.objects.get(parent_id=pk)
context = {'parentObj': parentObj}
return render(request, "students_management_app/parents-single.html",
context)
Template
{% extends 'main.html' %}
{% block content %}
<h1>A parent page for more details </h1>
<!-- <img src= "{{ buildingObj.buildingIMG1.url }}"> -->
<h1>{{parentObj.std_matricule}}</h1>
<br>
<h2>Father full name: {{parentObj.father_firstName}}
{{parentObj.father_surname}}</h2>
<br>
<h2>Mother full name: {{parentObj.mother_firstName}}
{{parentObj.mother_surname}}</h2>
<p>
Register date: {{parentObj.parent_createDate}}
</p>
<p><a href="{% url 'parents-list' %}">Add parents</a><br/></p>
<br/>
{% if parentObj.student_set.all %}
{% for student in parentObj.students_set.all %}
<h2>List of students</h2>
<p>{{student.std_matricule}}</p>
<p>{{student.std_firstname}} {{student.std_midlename}}
{{student.std_surname}}</p>
<p>{{student.std_sex}}</p>
{% endfor %}
{% endif %}
<p>No Student found in the database</p>
{% endblock content %}
<p>Footer</p>
The page is displaying well with all the information for the parent, but
not student data.
Thank you
