我在 django 中收到 No reverse match error 但它用於 urls.py

Question

我一直面臨這個問題。 我有一個 url 名稱后頁面詳細信息，但隨后也出現錯誤，請參見下面的錯誤屏幕截圖。

我的singlepost.html html頁面

<a href="{% url "post-detail-page" slug=post.slug %}">
    <h2>{{post.tractor_company}} || {{post.tractor_model}}</h2>
<pre><h5>{{post.implimentaion}}</h5>
{{post.farmer}}
Uplode Date : {{post.date}}</pre>
</a>
</div>

網址.py

from . import views
urlpatterns = [
    path("",views.starting_page,name = "starting-page"),
    path("posts",views.posts,name = "post-page"),
    path("posts/<slug:slug>",views.post_detail,name="post-detail-page"),
]

查看.py

from django import forms
from django.contrib.auth.models import User
from django.shortcuts import render, redirect ,get_object_or_404
from .models import Post, Farmer
# Create your views here.
from django.http import HttpResponseRedirect 
# Create your views here.
def starting_page(request):
    return render(request,"tractor/index.html")

def posts(request):
    qs = Post.objects.all()  
    context = {"posts":qs}
    return render(request,"tractor/all-post.html",context)
    
def add_post(request):
    pass


def post_detail(request,slug):
    indentified_post = get_object_or_404(Post,slug=slug)
    return render(request,"blog/post-detail.html",{'post':indentified_post})

我正在遍歷帖子並使用 post-detail.html 頁面

所有帖子.html。

{% load static %}

{% block title %}
All Tractors
{% endblock  %}

{% block content%}
<section id="all_events">
    <br>
    <h1 style="text-align:center;">All Tractors</h1>
    <ul>
      {% for post in posts %}
        <br>
        {% include "tractor/includes/singlePost.html" %}
      {% endfor %}
    </ul>

</section>
{% endblock %}

Answer 1

而不是 "{% url "post-detail-page" slug=post.slug %}" 使用這個：

"{% url 'post-detail-page' post.slug %}"

Answer 2

嘗試這個：

"{% url 'insert-app-name-here:post-detail-page' %}"
