Python 如何解决Django中没有反向匹配的问题

我有这个错误，当我试图发布一个新的职位，它没有给我之前的错误，直到我添加了文件上传功能，以创建职位页面，现在当我试图创建后上传文件在获取这个错误

NoReverseMatch at/post/new/ 未找到“发布详细信息”的反向项“发布详细信息”不是有效的视图函数或模式名称。

下面是我的views.py代码

从django.url导入路径
从.views导入（PostListView、PostCreateView、，
PostUpdateView、PostDetailView、PostDeleteView、UserPostListView）
从…起导入视图

来自django.contrib导入管理
从django.contrib.auth导入视图作为auth_视图
从django.url导入路径，包括
从django.conf导入设置
从django.conf.url.static导入静态
从用户导入视图作为用户视图

如果设置为.DEBUG：
urlpatterns+=静态（settings.static\u URL，document\u root=settings.static\u root）

这是我的模板post_detail.html代码

{% extends "blog/base.html" %}
{% block content %}

        <article class="media content-section">
              <img class="rounded-circle article-img" src="{{ object.author.profile.image.url }}">
              <div class="media-body">
                <div class="article-metadata">
                  <a class="mr-2" href="{% url 'posts:user-posts' object.author.username %}">{{ object.author }}</a>
                  <small class="text-muted">{{ object.date_posted|date:"F d, Y" }}</small>
                    {% if object.author == user %}
                        <div>
                            <a class="btn btn-secondary btn-sm mt-1 mb-1" href="{% url 'posts:post-update' object.id %}">Update</a>
                            <a class="btn btn-danger btn-sm mt-1 mb-1" href="{% url 'posts:post-delete' object.id %}">Delete</a>
                        </div>
                    {% endif %}
                </div>
                <h2 class="article-title">{{ object.title }}</h2>
                <p class="article-content">{{ object.content }}</p>
              </div>
        </article>

{% endblock %}

{%extends“blog/base.html”%}
{%block content%}
{{object.date{u posted}日期：“fd，Y”}
{%if object.author==user%}
{%endif%}
{{object.title}}
{{{object.content}
{%endblock%}

该应用程序的工作方式是，当你发布的帖子出现在由用户_posts.html控制的主页上时，代码如下

{% extends "blog/base.html" %}
{% block content %}
    <h2 class="mb-3">Posts by {{ views.kwargs.username }} ({{ page_obj.paginator.count }})</h2>
    {% for post in posts %}
        <article class="media content-section">
              <img class="rounded-circle article-img" src="{{ post.author.profile.image.url }}">
              <div class="media-body">
                <div class="article-metadata">
                  <a class="mr-2" href="{% url 'posts:user-posts' post.author.username %}">{{ post.author }}</a>
                  <small class="text-muted">{{ post.date_posted|date:"F d, Y" }}</small>
                </div>
                <h2><a class="article-title" href="{% url 'posts:post-detail' post.id %}">{{ post.title }}</a></h2>
                <p class="article-content">{{ post.content }}</p>
              </div>
        </article>
    {% endfor %}
    {% if is_paginated %}

        {% if page_obj.has_previous %}
            <a class="btn btn-outline-info mb-4" href="?page=1">First</a>
            <a class="btn btn-outline-info mb-4" href="?page={{ page_obj.previous_page_number }}">Previous</a>
        {% endif %}

        {% for num in page_obj.paginator.page_range %}
            {% if page_obj.number == num %}
                <a class="btn btn-info mb-4" href="?page={{ num }}">{{ num }}</a>
            {% elif num > page_obj.number|add:'-3' and num < page_obj.number|add:'3' %}
                <a class="btn btn-outline-info mb-4" href="?page={{ num }}">{{ num }}</a>
            {% endif %}
        {% endfor %}

        {% if page_obj.has_next %}
            <a class="btn btn-outline-info mb-4" href="?page={{ page_obj.next_page_number }}">Next</a>
            <a class="btn btn-outline-info mb-4" href="?page={{ page_obj.paginator.num_pages }}">Last</a>
        {% endif %}

    {% endif %}
{% endblock %}

{%extends“blog/base.html”%}
{%block content%}
按{views.kwargs.username}}（{{page_obj.paginator.count}}）发布的帖子
{posts%%中的post为%s}
{{发布日期{发布日期：“F d，Y”}
{{post.content}
{%endfor%}
{%if已分页%}
{%如果页面_obj.has_previous%}
{%endif%}
{page_obj.paginator.page_range%}
{%if page_obj.number==num%}
{%elif num>page_obj.number | add:'-3'和num

这是回溯期间显示为粗体的错误

C:\Users\HOPE\Desktop\Django\Blog\u project\Blog\views.py格式为\u valid 返回super（）.form\u有效（form）

获取绝对url中的C:\Users\HOPE\Desktop\Django\Blog\u project\Blog\models.py

---

返回反向（'post-detail'，kwargs={'pk'：self.pk}）问题出在这一行的“user_posts.html”中

    <h2><a class="article-title" href="{% url 'posts:post-detail' post.id %}">{{ post.title }}</a></h2>

这一行应该包括：

    <h2><a class="article-title" href="{% url 'posts:post-detail' pk=post.id %}">{{ post.title }}</a></h2>

如果我们看一下你的“url.py”-

    path('post/<int:pk>/', PostDetailView.as_view(), name="post-detail"),

路径（'post/'，PostDetailView.as_view（），name=“post detail”）， 我们看到您访问此url的方式是使用整数pk。

---

因此，在html文件中，当尝试反转到此url时，请确保指定pk=post.id。这样，django就知道要将哪些信息传递到url。

请只发布相关代码
