You can use Django messages framework to achieve this.

In Your views.py file first import messages

from django.contrib import messages

then do something like this

if request.method == 'POST':
        form = AddStudentForm(request.POST, request.FILES)
        if form.is_valid():
            student = form.save(commit=True)
            student.save()
            messages.success(request, 'student with name  {}  added.'.format(student.name))
            return redirect('admin:add_student')
        else:
            for error in form.errors:
            messages.error(request, sign_in_form.errors[error])
            return redirect(request.path)
else:
    form = AddStudentForm()
    return render(request, 'admin/add_student.html', {'form': form})

In your HTML File, access messages something like

        {% if message.tags == 'error' %}
            <!-- bootstrap alert -->
            <div class="alert alert-warning alert-dismissible fade show" role="alert">
                <strong>{{ message }}</strong>
                <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
            </div>
        {% endif %}
        {% if message.tags == 'success' %}
            <!-- bootstrap alert -->
            <div class="alert alert-success alert-dismissible fade show" role="alert">
                <strong>{{ message }}</strong>
                <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
            </div>
        {% endif %}
    {% endfor %}

in your views.py pass the form with errors like this

if request.method == 'POST':
    form = AddStudentForm(request.POST, request.FILES)
    if form.is_valid():
        student = form.save(commit=True)

        student.save()

        messages.success(request, 'student with name  {}  added.'.format(student.name))
        return redirect('admin:add_student')

    return render(request, 'admin/add_student.html', {'form': form}) 
else:
    form = AddStudentForm()
    return render(request, 'admin/add_student.html', {'form': form})

That means you should remove the else part and in your template code

{% if form.errors %}
    <div class="alert alert-danger">
        {{ form.errors }}
    </div>
{% endif %}
