Django “的反面；URL"；带参数'；（id）和#x27；没有找到。尝试了1个模式：'；URL<；内部：ID>'；

我有这个错误，我不能得到我的列表的id，我得到一个错误。我正在尝试创建一个更新按钮来编辑添加到数据库中的数据

这是我的 我的应用程序中的views.py

    from django.shortcuts import render, redirect
    from gomo_web_system.forms import UserForm,NewMasterForm

    from django.contrib.auth import authenticate, login, logout
    from django.http import HttpResponseRedirect, HttpResponse

    from gomo_web_system.models import masterList

    from django.contrib import messages


def index(request):

    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')

        user = authenticate(username=username, password=password)


        if user is not None:
            login(request, user)
            return render(request, 'gomo_web_system/main_menu.html')
        else:
            messages.info(request, 'Username or Password is incorrect')

    context = {}
    return render(request, 'gomo_web_system/index.html', context)

def user_logout(request):
    logout(request)
    return HttpResponseRedirect(reverse('index'))

@login_required

@login_required
def it_master_list(request):
    master_list = masterList.objects.order_by('projectName')
    master_dict = {'master':master_list}
    return render(request, 'gomo_web_system/IT/it_master_list.html', context=master_dict)

@login_required
def it_create_master_list(request):

    form = NewMasterForm()

    if request.method == 'POST':
        #print('printring POST:', request.POST)
        form = NewMasterForm(request.POST)

        if form.is_valid():
            form.save()
            return redirect('gomotion:master_list')

    context = {'form':form}
    return render(request, 'gomo_web_system/IT/it_add_master_list.html', context)

def it_update_master_list(request, id):
    form = NewMasterForm()

    context = {'form':form}
    return render(request, 'gomo_web_system/IT/it_add_master_list.html', context)

这是我的应用程序中的我的 myapp/url.py

from django.conf.urls import url
from gomo_web_system import views

app_name = 'gomotion'

urlpatterns = [
    url('main/',views.main_menu, name="main"),
    url('itHome/',views.it_home, name="home"),
    url('itMasterList/', views.it_master_list, name="master_list"),

    url('itUpdateMasterList/<int:id>/',views.it_update_master_list, name="update_master_list"),
]

此文件在“master_list.id”粗体文本中获取.id错误

您必须将需要更新的实例传递给视图

def it_update_master_list(request, id):
    instance = get_object_or_404(masterList, id=id)
    form = NewMasterForm(request.POST or None, request.FILES or None, instance=instance)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return redirect('/')
        context = {'form':form, "instance": instance,}
        return render(request, 'your_form.html', context)

请与我们共享

update\u master\u list

。没有使用update master的html文件，它将直接添加到我的add\u master\u list。先生，错误是我的html文件。当我将“master\u list.id”放入我的html文件时，我收到一个错误。有代码是您的更新视图不正确，请按图所示进行更正，然后查看仍然存在错误您的创建视图是否正常工作？我已更新编辑视图、检查和回复

def it_update_master_list(request, id):
    instance = get_object_or_404(masterList, id=id)
    form = NewMasterForm(request.POST or None, request.FILES or None, instance=instance)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return redirect('/')
        context = {'form':form, "instance": instance,}
        return render(request, 'your_form.html', context)
