我收到 NoReverseMatch 错误： NoReverseMatch 在 / 未找到参数为 '(22, '')' 的 'post-detail' 反转。尝试了 1 个模式：['post/(?P[0-9]+)/(?P[-a-zA-Z0-9_]+)/$']
不知道如何解决这个问题，这里是一些代码：
urls.py
urlpatterns=[
path('', PostListView.as_view(), name='home'),
path('post/new/<slug:slug>/', views.create_post, name='post-create'),
path('post/<int:pk>/<slug:slug>/', views.post_detail, name='post-detail'),
path('like/<slug:slug>/', views.like, name='post-like'),
path('post/<int:pk>/<slug:slug>/update/', PostUpdateView.as_view(), name='post-update'),
path('post/<int:pk>/<slug:slug>/delete/', views.post_delete, name='post-delete'),
path('search_posts/', views.search_posts, name='search_posts'),

当我点击主页链接时，我收到了上面提到的错误，不确定这个模板是什么原因导致的？有什么想法吗？
