Python Django-删除按钮未重定向到正确路径

我遵循一个教程，使网站的待办事项清单。在尝试实现删除按钮时，我遇到了这个错误

找不到页面（404）请求方法：获取请求 URL:'删除'%20个内容。id%20%25 Django使用todo.URL中定义的URLconf尝试了以下URL 模式，按此顺序： admin/[name='home']delete/“[name='delete']当前 路径{%url'delete'things.id%，与其中任何一个都不匹配

相关代码： 视图.py

from django.shortcuts import render, redirect
from .models import List
from .forms import ListForm
from django.contrib import messages
# Create your views here.
def home(request):
    if request.method == 'POST':
        form = ListForm(request.POST or None)

        if form.is_valid():
            form.save()
            all_items = List.objects.all
            messages.success(request, ('Item Has Been Added To List!'))
            return render(request, 'home.html', {'all_items': all_items})

    else:
        all_items = List.objects.all
        return render(request, 'home.html', {'all_items': all_items})

def delete(request, list_id):
    item = List.objects.get(pk=list_id)
    item.delete()
    messages.success(request, ('Item Has Been Deleted!'))
    return redirect('home')

from django.urls import path
from . import views
urlpatterns = [
    path('', views.home, name="home"),
    path('delete/<list_id>', views.delete, name="delete"),
]

home.html

<tr>
            <td>{{ things.item }}</td>
            <td><center>{{ things.completed }}</center></td>
            <td><center><a href = "{% url 'delete' things.id %}"> Delete</a></center></td>
</tr> 

{{things.item}
{{things.completed}}

url.py

from django.shortcuts import render, redirect
from .models import List
from .forms import ListForm
from django.contrib import messages
# Create your views here.
def home(request):
    if request.method == 'POST':
        form = ListForm(request.POST or None)

        if form.is_valid():
            form.save()
            all_items = List.objects.all
            messages.success(request, ('Item Has Been Added To List!'))
            return render(request, 'home.html', {'all_items': all_items})

    else:
        all_items = List.objects.all
        return render(request, 'home.html', {'all_items': all_items})

def delete(request, list_id):
    item = List.objects.get(pk=list_id)
    item.delete()
    messages.success(request, ('Item Has Been Deleted!'))
    return redirect('home')

from django.urls import path
from . import views
urlpatterns = [
    path('', views.home, name="home"),
    path('delete/<list_id>', views.delete, name="delete"),
]

从django.url导入路径
从。导入视图
URL模式=[
路径（“”，views.home，name=“home”），
路径（'delete/'，views.delete，name=“delete”），
]

url.py:

from django.urls import path
from . import views
urlpatterns = [
    path('', views.home, name="home"),
    path('delete/<int:list_id>/', views.delete, name="delete"),
]

路径（'delete/'，views.delete，name=“delete”），

您需要在url中指定

int

类型

---

还有尾随的

/

您需要一个正则表达式来表示一个数字即将到来

path('delete/(?P<list_id>)[\d]+)/$', views.delete, name="delete"),

path（'delete/（？P）[\d]+）/$”，views.delete，name=“delete”），

请显示

views.home

的代码。我已经将其添加到了主帖子中。您不需要

路径（'delete/（？P）/$'，views.delete，name=“delete”），

相反？@MattCremeens错误保持不变，并说：使用todo.URL中定义的URLconf，Django尝试了这些URL模式，顺序是：admin/[name='home']delete/（？P）/$[name='delete']当前路径，{%url'delete'things.id%与任何一个都不匹配。请查看我的答案。我相信这应该可以。我编辑了答案，你还需要有尾随的“/”，django才能找到它。错误现在仍然存在，显示我所做的更改更新：这起作用了。显然，愚蠢的我，尽管只是在错误处刷新，应该重新启动程序服务器并修复错误，但我从localhost:8000重新启动，它仍然有效。错误仍然存在，现在提到的是新的URL模式。这可能与html中的href标记有关吗？在我运行服务器的cmd提示符中显示的警告
