uploaded video not showing up - django

Question

So I have uploaded videos for a class model for an educational website but that video is not being rendered. What can I do to render it?
My models.py:
class Class(models.Model):
title = models.CharField(max_length=100)
video = models.FileField(upload_to='class/class_videos',null=True,
validators=[FileExtensionValidator(allowed_extensions=['MOV','avi','mp4','webm','mkv'])])
def __str__(self):
return self.title
class Course(models.Model):
title = models.CharField(max_length=100)
image = models.ImageField(upload_to='class/instructor_pics', null=True)
instructor = models.CharField(max_length=100)
instructor_image = models.ImageField(upload_to='class/instructor_pics', null=True)
students = models.ManyToManyField(User, related_name='courses_joined', blank=True)
classes = models.ForeignKey(Class, on_delete=models.CASCADE, null=True)
slug = models.SlugField(max_length=200, unique=True)
description = models.TextField(max_length=300, null=True)
created = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['-created']
def __str__(self):
return self.title
My views.py:
class CourseDetailView(LoginRequiredMixin, DetailView):
model = Course
template_name = 'class/course.html'
My html file :
{% extends "class/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<h1>{{ object.title }}</h1>
{{ object.classes.video }}
{% endblock content %}
The output is the title of the class and the <name>.mp4 filename where name is the name of the video file I uploaded. But I want the video to be rendered. Can anyone help me ?
Thanks in advance!
