即使在正确的网址和视图之后也会出现 NoReverseMatch 错误

Question

即使在urls.py中创建路径并在views.py中创建函数后仍收到NoReversedMatch的错误消息 当我手动输入 url 时，它可以正常工作，因此路径没有错误，请有人帮助我

NoReverseMatch at /mcq_web/
Reverse for 'quizes' not found. 'quizes' is not a valid view function or pattern name.

出现错误的html是

href = "{% url 'quizes' quiz_type.id %}"

这是我的 urls.py

from django.contrib import admin
from django.urls import path
from . import views

urlpatterns = [
    path('', views.show_quiz, name="quiz_show"),
    path('add/',views.add_user, name ="new user"),
    path('show_quiz/', views.show_quiz, name="quiz_types"),
    path('<int:quiz_type_id>/quizes/', views.quizes, name="ShortedQuizTypes"),
]

这是我的views.py 部分的错误

def quizes(request,quiz_type_id):
    quiz_type = get_object_or_404( Quiz_types,pk = quiz_type_id)
    quizes = quiz_data.objects.all()
    quiz_types = Quiz_types.objects.all()
    details = {'quiz':quizes,'quiz_type':quiz_type,'quiz_types':quiz_types}
    return render(request,'shorted_show_quiz.html',{'details':details})

以防万一这是我的全部观点。py

from django.shortcuts import render
from django.shortcuts import get_object_or_404
from .models import quiz_data,quiz,quiz_history,Quiz_types,options,user
from .forms import user_form 
# Create your views here.

# function to show quiz by type
def quizes(request,quiz_type_id):
    quiz_type = get_object_or_404( Quiz_types,pk = quiz_type_id)
    quizes = quiz_data.objects.all()
    quiz_types = Quiz_types.objects.all()
    details = {'quiz':quizes,'quiz_type':quiz_type,'quiz_types':quiz_types}
    return render(request,'shorted_show_quiz.html',{'details':details})


# function to add new users
def add_user(request):
    if request.method == 'POST':
        form = user_form(request.POST)
        if form.is_valid:
            form.save()


# function to show quiz by type
def show_quiz(request):
    quizes = quiz_data.objects.all()
    quiz_types = Quiz_types.objects.all()
    details = {'quiz':quizes,'quiz_types':quiz_types}
    return render(request,'show_quiz.html',{'details':details})

我尝试清除缓存数据（在清除缓存之前我已取消应用所有迁移）通过手动输入网址重新启动服务器多次，其工作但不在模板中它不断抛出错误我应该做什么我被卡住了

Exception Type: NoReverseMatch at /mcq_web/
Exception Value: Reverse for 'quizes' not found. 'quizes' is not a valid view function or pattern name.

Answer 1

视图的名称是

ShortedQuizTypes

，而不是

quizes

，所以：

<a href="{% url 'ShortedQuizTypes' quiz_type.id %}"></a>
