python - 未找到带有参数“（”，）”的“后详细信息”的反向。尝试了 1 种模式：['post/(?P[0-9]+)/$']
问题描述
我正在开发一个小型 Django 博客项目，但遇到了这个错误：-
NoReverseMatch at /

这是 Django 代码：-urls.py
from django.urls import path
from .views import (
PostDetailView,
PostUpdateView,
PostDeleteView,
PostListView,
about,
post_create,
Profileview
)
urlpatterns = [
path("", PostListView.as_view(), name="blog-home"),
path("about/", about, name="blog-about"),
path("profileview/<name>", Profileview, name="blog-profile"),
path("post/<int:pk>/", PostDetailView.as_view(), name="post-detail"),
path("post/<int:pk>/update/", PostUpdateView.as_view(), name="post-update"),
path("post/<int:pk>/delete/", PostDeleteView.as_view(), name="post-delete"),
path("post_create/", post_create, name="post_create"),
]
这是views.py文件：-
from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Post
from django.views.generic import ListView
from django.contrib.auth.models import User
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from django.views.generic import DetailView, UpdateView, DeleteView
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .forms import PostForm
from django.db.models import Q
class PostDetailView(DetailView):
model = Post
class PostListView(ListView):
model = Post
template_name = 'blog/home.html'
context_object_name = 'posts'
ordering = ['-date_posted']
............
............
这是base.html文件：-

我认为必须对 urls.py 或 base.html 文件中的一些更改做一些事情。由于问题出现在根 URL 中。我已经尝试在这里进行更改，但似乎没有任何东西可以解决这个问题。这是home.html文件：-
{% extends 'blog/base.html' %}
{% block slider%}
<div class="slider">
<input name="input-slider" id="input-slide-0" type="radio" class="input-slide input-slide-num" style="display: none;" />
<input name="input-slider" id="input-slide-1" type="radio" class="input-slide input-slide-num" style="display: none;" />
<input name="input-slider" id="input-slide-2" type="radio" class="input-slide input-slide-num" style="display: none;" />
<input name="input-slider" id="input-slide-3" type="radio" class="input-slide input-slide-num" style="display: none;" />
<input name="input-slider" id="input-slide-autoplay" type="radio" class="input-slide" checked style="display: none;" />
<ul>
<li class="slide-0"></li>
<li class="slide-1"></li>
<li class="slide-2"></li>
<li class="slide-3"></li>
</ul>
<div class="slide-description">

<a href="{% url 'post-detail' mostliked1.id %}" class="readmorebutton">Read More</a>
