我是 django 的新手并且被 slug 击中了，现在我很困惑如何使用 ID 参数并转换为 slug

网址.py

 url(r'^deletePost/(?P<slug>[\w-]+)/$', views.delete_post, name='delete_post') 

模板

<form method="POST" action="{% url 'delete_post' id=post.id %}">{% csrf_token %} 
 
    <button type="submit" class="btn btn-danger"> &nbsp Delete</button> 
</form> 

View .py

def delete_post(request,slug): 
    posts=Post.objects.get(slug=slug) 
    if request.method == 'POST': 
        posts.delete() 
        return redirect("home") 

我如何使用 slug 和 id 删除创建的帖子

感谢任何帮助。提前致谢

请您参考如下方法:

在我看来，您不想将 id 转换为 slug。您可以让您的应用程序足够灵活，以便您可以通过 slug 或 id 进行删除。您只需要相应地处理参数。

所以，你可以这样做:

网址.py

url(r'^deletePost/(?P<slug>[\w-]+)/$', views.delete_post, name='delete_post_by_slug'), 
url(r'^deletePost/(?P<id>[0-9]+)/$', views.delete_post, name='delete_post_by_id') 

在 View 中:

def delete_post(request, slug=None, id=None): 
    if slug: 
        posts=Post.objects.get(slug=slug) 
    if id: 
        posts=Post.objects.get(id=id) 
    #Now, your urls.py would ensure that this view code is executed only when slug or id is specified 
 
    #You might also want to check for permissions, etc.. before deleting it - example who created the Post, and who can delete it. 
    if request.method == 'POST': 
        posts.delete() 
        return redirect("home") 

请注意，您可以将 2 个 URL 模式压缩为一个 - 但这种方法可以保持它的可读性和可理解性。一旦您对 django 框架等感到满意，我将让您弄清楚 URL 合并。
