[Answered ]-Try to Return dataset as a table with request of postman

At first, you can simply apply @method_decorator just above the class itself using name="dispatch'.

Secondly, try to use many=True in BookSerializer and also use Book.objects.all() to retrieve all instances of Book model, like the following:

from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required

@method_decorator(login_required(login_url='login/'), name='dispatch')
class AddBookAPIView(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'book.html'

    def post(self, request):
        book_serializer = BookSerializer(data=request.data)
        if book_serializer.is_valid():
            book_serializer.save()
            return redirect('home')

        return Response({'message': book_serializer.errors})

    def get(self, request):
        book = Book.objects.all()
        serializer = BookSerializer(book, many=True)
        return Response({'serializer': serializer, 'books': serializer.data})

Try to modify the template so that it would show the list of all books, like the following:

{% load rest_framework %}
<title>Books</title>

{% block title %}
    <h3>View Books</h3>
{% endblock %}

{% block content %}
    <table class="table">
        <thead>
            <tr>
                <th>Name</th>
                <th>Publication Date</th>
                <th>Publisher</th>
                <th>Description</th>
            </tr>
        </thead>
        <tbody>
            {% for book in books %}
                <tr>
                    <td>{{ book.name }}</td>
                    <td>{{ book.publication_date }}</td>
                    <td>{{ book.publisher }}</td>
                    <td>{{ book.description }}</td>
                </tr>
            {% endfor %}
        </tbody>
    </table>
{% endblock %}
