django - 我得到了错误。NoReverseMatch at /delete_mat/11/ 在 Django 的一个应用程序中

问题描述

万岁开发者。我在现有的 Django 项目中创建了第二个应用程序。应用程序中的 urls.py 路由工作正常，但视图 edit_mat、update_mat 和 delete_mat，尽管执行了操作仍访问数据库，但不会重新加载索引页面。我不访问数据库的视图工作得很好。不知道还能做什么。你能帮我吗？

错误：

view.py 应用程序

from django.shortcuts import render, redirect
from materiais.models import EspecComponentes, Componente, Codigo, EspecMaterial
from materiais.forms import EspecComponentesForm



# Create your views here.

...

def create_mat(request):
    form_mat = EspecComponentesForm(request.POST or None)
    if form_mat.is_valid():
        form_mat.save()
        return redirect('material')

def view_mat(request, pk):
    data = {}
    data['db'] = EspecComponentes.objects.get(pk=pk)
    return render(request, 'materiais/view.html', data)

def edit_mat(request, pk):
    data = {}
    data['db'] = EspecComponentes.objects.get(pk=pk)
    data['form_mat'] = EspecComponentesForm(instance=data['db'])
    return render(request, 'materiais/form.html', data)

def update_mat(request, pk):
    data = {}
    data['db'] = EspecComponentes.objects.get(pk=pk)
    form_mat = EspecComponentesForm(request.POST or None, instance=data['db'])
    if form_mat.is_valid():
        form_mat.save()
        return redirect('material')

def delete_mat(request, pk):
    db = EspecComponentes.objects.get(pk=pk)
    db.delete()
    return redirect('material')

urls.py 应用程序

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


app_name = 'materiais'

urlpatterns = [

  #ok  path('material/', views.material, name='material'),
  #ok path('form_mat/', views.form_mat, name='form_mat'), 
    path('create_mat/', views.create_mat, name='create_mat'),
    path('view_mat/<int:pk>/', views.view_mat, name='view_mat'),
    path('edit_mat/<int:pk>/', views.edit_mat, name='edit_mat'),
    path('update_mat/<int:pk>/', views.update_mat, name='update_mat'),
    path('delete_mat/<int:pk>/', views.delete_mat, name='delete_mat'),

]

视图工作，但不重定向到视图名称并返回错误：NoReverseMatch at /edit_mat/11/ NoReverseMatch at /update_mat/11/ NoReverseMatch at /delete_mat/11/

urls.py 项目
