使用django创建网页，按照书本上设置的为什么会老是报告Page not Found？

按照从入门到实践Django章节的介绍，创建edit_entru功能，但是页面一直报错，报错内容如下：

Page not found (404)
Request Method:    GET
Request URL:    http://localhost:8000/topics/%7B%25%20url%20'learning_logs:edit_entry'%20entry.id%20%25%20%7D
Using the URLconf defined in learning_log.urls, Django tried these URL patterns, in this order:

admin/
[name='index']
topics/ [name='topics']
topics/<int:topic_id> [name='topic']
new_topic/ [name='new_topic']
new_entry/<int:topic_id>/ [name='new_entry']
topics/edit_entry/<int:entry_id>/ [name='edit_entry']
The current path, topics/{% url 'learning_logs:edit_entry' entry.id % }, didn’t match any of these.

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

具体的代码如下：
url.py:

'''定义learning_logs的url模式'''
from django.urls import path
from . import  views
app_name = 'learning_logs'
urlpatterns = [
    #主页
    path('',views.index,name = 'index'),
    #显示所有的主题
    path('topics/',views.topics,name='topics'),
    #特定主题的详细界面
    path('topics/<int:topic_id>', views.topic,name='topic'),
    #用于添加新主题的页面
    path('new_topic/',views.new_topic,name = 'new_topic'),
    path('new_entry/<int:topic_id>/',views.new_entry,name='new_entry'),
    path('topics/edit_entry/<int:entry_id>/',views.edit_entry,name = 'edit_entry'),

]

视图views.py:

from django.shortcuts import render,redirect
from .models import Topic,Entry
from .forms import TopicForm,EntryForm
# Create your views here.

def index(request):
    '''学习笔记的主页'''
    return render(request,'learning_logs/index.html')

def topics(request):
    '''显示所有主题'''
    topics = Topic.objects.order_by('date_added')
    context = {'topics':topics}
    return render(request, 'learning_logs/topics.html',context)

def topic(request,topic_id):
    '''显示单个主题及其所有的条目'''
    topic = Topic.objects.get(id=topic_id)
    entries = topic.entry_set.order_by('-date_added')
    context = {'topic':topic,'entries':entries}
    return render(request,'learning_logs/topic.html',context)

def new_topic(request):
    '''添加新主题'''
    if request.method != 'POST' :
        #未提交数据，创建一个新表单
        form = TopicForm()
    else:
        #post提交数据：对数据进行处理
        form = TopicForm(data=request.POST)
        if form.is_valid():
            form.save()
            return redirect('learning_logs:topics')

    #显示空表单或指出表单数据无效
    context = {'form':form}
    return render(request,'learning_logs/new_topic.html',context)

def new_entry(request,topic_id):
    '''在特定主题中添加条目'''
    topic = Topic.objects.get(id = topic_id)
    if request.method != 'POST':
        #未提交数据，创建一个空表单
        form = EntryForm()
    else:
        #POST提交的数据，对数据进行处理
        form = EntryForm(data = request.POST)
        if form.is_valid():
            new_entry = form.save(commit=False)
            new_entry.topic = topic
            new_entry.save()
            return redirect('learning_logs:topic',topic_id = topic_id)
    #显示空表单或指出表单的数据无效
    context = {'topic':topic,'form':form}
    return render(request,'learning_logs/new_entry1.html',context)

def edit_entry(request,entry_id):
    '''编辑既有条目'''
    entry = Entry.objects.get(id=entry_id)
    topic = entry.topic
    if request.method != 'POST':
        #初次尝试请求：使用当前条目填充表单
        form = EntryForm(instance=entry)
    else:
        #POST提交的数据：对数据进行处理
        form = EntryForm(instance=entry,data=request.POST)
        if form.is_valid():
            form.save()
            return redirect('learning_logs:topic',topic_id=topic.id)
    context = {'entry':entry,'topic':topic,'form':form}
    return render(request,'learning_logs/edit_entry.html',context)

模板 edit_entry.html:

{%  extends 'learning_logs/base.html'}
{% block content %}
<p>
    <a href="{% url 'learning_logs:topic',topic.id}">{{topic}}</a>
</p>
<p>Edit entry:</p>
<form action="{% url 'learning_logs:edit_entry' entry.id %}" method = 'post'>
    {% csrf_token %}
    {{form.as_p}}
    <button name="submit">Save changes</button>
</form>
{% endblock content %}

把链接添加到具体的topic下：

{% extends 'learning_logs/base.html' %}
{% block content %}
<p>
    Topic:{{topic}}
</p>
<p>
    Entries:
</p>
<p>
    <a href="{% url 'learning_logs:new_entry' topic.id %}">Add new entry</a>
</p>
<ul>
    {% for entry in entries %}
        <li>
            <p>
                {{ entry.date_added | date:'M d,Y H:i'}}
            </p>
            <p>
                {{entry.text | linebreaks}}
            </p>
            <p>
                <a href="{% url 'learning_logs:edit_entry' entry.id % }">Edit entry</a>
            </p>
        </li>
    {% empty %}
        <li>
            There are no entries for this topic yet.
        </li>
    {% endfor %}
</ul>
{% endblock content %}

点击Edit entry按钮，为啥子url会是http://localhost:8000/topics/%7B%%20url%20'learning_logs:edit_entry'%20entry.id%20%%20%7D
不应该是：
http://localhost:8000/eidt_entry/1?
前面的匹配上也没有写topics，不知道后面django创建页面的时候会加上topics

a标签herf传错了被。

<a href="/{{entry.id}}">Edit entry</a>

你期待的是http://localhost:8000/eidt_entry/1?
说明在当前页面点击的时候只需要跳转到 当前路径下/entry.id 这个链接
没用过你那种模版语法，不知道是写错了还是你那个版本django不支持。

我发现从哪开始进不去的，就在那个html上面找错一般来说就没错。 html基本都是typo，vs上有没有语法高亮呢？比如少了一个百分号这种提示一下？
