Question

我认为这是一个非常简单的问题，但我不知道出什么问题了。我保留了错误。

它说：

异常类型：NoReverseMatch

异常值：带有关键字参数的“ post_publish”的取反   找不到'{'pk'：''}'。尝试了1种模式：   ['\ ^ post / \（\？P（？P [^ /] +）\\ d \ + \）/ publish / \ $$']

例外   位置：C：\ Users \ umts \ lib \ site-packages \ django \ urls \ resolvers.py   _reverse_with_prefix，第622行

你们可以帮助我解决这些问题吗？

urls.py

urlpatterns = [
    path('', views.post_list, name='post_list'),
    path('post/<int:pk>/', views.post_detail, name='post_detail'),
    path('post/new', views.post_new, name='post_new'),
    path('post/<int:pk>/edit/', views.post_edit, name='post_edit'),
    path(r'^drafts/$', views.post_draft_list, name='post_draft_list'),
    path(r'^post/(?P<pk>\d+)/publish/$', views.post_publish, name='post_publish'),
    path(r'^post/(?P<pk>\d+)/remove/$', views.post_remove, name='post_remove'),
    path(r'^post/(?P<pk>\d+)/comment/$', views.comment_add, name='comment_add'),
    path(r'^comment/(?P<pk>\d+)/approve/$', views.comment_approve, name='comment_approve'),
    path(r'^comment/(?P<pk>\d+)/remove/$', views.comment_remove, name='comment_remove'),
]

我将仅显示“注释添加”代码

views.py

def post_detail(request, pk):
    post = get_object_or_404(Post, pk=pk)
    return render(request, 'blog/post_detail.html', {'post': post})


# comment 더하기
def comment_add(request, pk):
    post=get_object_or_404(Post, pk=pk)
    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = post
            comment.save()
            return redirect('post_detail', pk=post.pk)
    else:
        form=CommentForm()
    return render(request, 'blog/post_detail.html') #, {'form':form})

您可以忽略韩语单词。但是，我要添加注释。

找不到带有关键字参数'{'pk'：'2'}'的'post_list'。尝试了1种模式：['$']
