Delete confirmation in django

Question

I am working on a project in django. I have this part of code, when I want to delete an album, it shows Yes or No to choose, but the problem is, whatever the choice I make, it always delete the album. I know I have to add something to the confirmation option but I don't want where or what.

<form action="{% url 'music:delete_album' album.id %}" method="post" style="display: inline;">
                                {% csrf_token %}
                                <input type="hidden" name="album_id" value="{{ album.id }}" />
                                <button type="submit" onclick="confirm('Are you sure ?')" class="btn btn-default btn-sm">
                                    <span class="glyphicon glyphicon-trash"></span>
                                </button>
                            </form>

and this is the delete_album view :

def delete_album(request, album_id):
    album = Album.objects.get(pk=album_id)
    album.delete()
    albums = Album.objects.filter(user=request.user)
    return render(request, 'music/index.html', {'albums': albums})

Answer 1

Ok, It could be validated before to submit your form. If you copy the next snipped then It will validate :)

<form action="{% url 'music:delete_album' album.id %}" 
    method="post" style="display: inline;" onsubmit="window.mytest()">
    {% csrf_token %}
    <input type="hidden" name="album_id" 
        value="{{ album.id }}" />
    <button type="submit" class="btn btn-default btn-sm">
        <span class="glyphicon glyphicon-trash"></span>
    </button>
</form> 
<script type="text/javascript">window.mytest = function() { var isValid = confirm('Are you sure ?');if (!isValid) { event.preventDefault();  alert("It wont delete. Yay!");}}</script>
