Django表单提交重定向到另一个URL

Question

请帮助操作设置为=“。”，但是django重定向到另一个URL

views.py

def post_detail(request, year, month, day, post):
    post = get_object_or_404(Post, slug=post,
                             status='published',
                             publish__year=year,
                             publish__month=month,
                             publish__day=day)

    # List of active comments for this post
    comments = post.comments.filter(active=True)

    new_comment = None

    if request.method == 'POST':
        # A comment was posted
        comment_form = CommentForm(data=request.POST)
        if comment_form.is_valid():
            # Create Comment object but don't save to database yet
            new_comment = comment_form.save(commit=False)
            # Assign the current post to the comment
            new_comment.post = post
            new_comment.save()
    else:
        comment_form = CommentForm()

    return render(request,
                  'blog/post/detail.html',
                  {'post': post,
                   'comments': comments,
                   'new_comment': new_comment,
                   'comment_form': comment_form})

urls.py

from django.urls import path
from . import views

app_name = 'blog'

urlpatterns = [
    path('', views.PostListView.as_view(), name='post_list'),
    path('<int:year>/<int:month>/<int:day>/<slug:post>',
         views.post_detail,
         name='post_detail'),
    path('<int:post_id>/share/', views.post_share, name='post_share'),
]

detail.html

    <h2>Add a new comment</h2>
        <form action="." method="post">
            {{ comment_form.as_p }}
            {% csrf_token %}
            <p><input type="submit" value="Add comment"></p>
        </form>

当我单击“提交”按钮时，我希望它保留在此URL“ http://localhost:8000/blog/2019/11/20/one-more-post”上，但是它切断了塞子部分并重定向到此：“ http://localhost:8000/blog/2019/11/20/”，因此抛出的页面不发现错误“找不到页面（404）”
