删除django中的确认(Delete confirmation in django)

 我正在研究django的一个项目。 我有这部分代码，当我想删除一个专辑时，它显示是或否可供选择，但问题是，无论我做出什么选择，它总是删除专辑。 我知道我必须在确认选项中添加一些东西，但我不想要在哪里或什么。  
<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>
 
 这是delete_album视图：  
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})

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})

 一个选项，使用Linq：  
var doc = new HtmlDocument();
doc.LoadHtml(html: Resources.Html);

var startNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_1']");
var endNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_2']");

var parent = startNode.ParentNode;

var nodesYouWant = parent.ChildNodes
    .SkipWhile(node => node != startNode)   // skip all nodes up to the start node
    .Skip(1)                                // skip the start node
    .TakeWhile(node => node != endNode)     // take all nodes up to the next anchor
    .Where(node => node.Name == "div");     // select only div nodes
 
 要么：  
var currentNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_1']");
var endNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_2']");

var nodesYouWant = GetEnclosedNodes(currentNode, endNode).Where(node => node.Name == "div");

private static IEnumerable<HtmlNode> GetEnclosedNodes(HtmlNode currentNode, HtmlNode endNode)
{
    currentNode = currentNode.NextSibling;

    while (currentNode != null && currentNode != endNode)
    {
        yield return currentNode;

        currentNode = currentNode.NextSibling;
    }
}

One option, using Linq: 
var doc = new HtmlDocument();
doc.LoadHtml(html: Resources.Html);

var startNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_1']");
var endNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_2']");

var parent = startNode.ParentNode;

var nodesYouWant = parent.ChildNodes
    .SkipWhile(node => node != startNode)   // skip all nodes up to the start node
    .Skip(1)                                // skip the start node
    .TakeWhile(node => node != endNode)     // take all nodes up to the next anchor
    .Where(node => node.Name == "div");     // select only div nodes
 
Or: 
var currentNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_1']");
var endNode = doc.DocumentNode.SelectSingleNode("//a[@name = 'doc_id_2']");

var nodesYouWant = GetEnclosedNodes(currentNode, endNode).Where(node => node.Name == "div");

private static IEnumerable<HtmlNode> GetEnclosedNodes(HtmlNode currentNode, HtmlNode endNode)
{
    currentNode = currentNode.NextSibling;

    while (currentNode != null && currentNode != endNode)
    {
        yield return currentNode;

        currentNode = currentNode.NextSibling;
    }
}
