Django创建表单提交后重定向至新建页面失败问题求助

提交创建表单后无法重定向到新建页面，更新表单该功能正常。运行代码后出现 AttributeError 错误，提示'function' object has no attribute 'id'。

现有代码（views.py） #

@login_required(login_url='login')
def createRoom(request):
    form = RoomForm()
    topics = Topic.objects.all()
    if request.method == 'POST':
        topic_name = request.POST.get('topic')
        topic, created = Topic.objects.get_or_create(name=topic_name)

        Room.objects.create(
            host=request.user,
            topic=topic,
            name=request.POST.get('name'),
            assigned=request.user,
            status=request.POST.get('status'),
            priority=request.POST.get('priority'),
            type=request.POST.get('type'),
            description=request.POST.get('description'),
        )
        return render('room', pk=room.id)

    context = {'form': form, 'topics': topics, 'room': room}
    return render(request, 'room/room_form.html', context)

错误信息 #

Traceback (most recent call last):
  File "C:\Users\mikha\issue_env\lib\site-packages\django\core\handlers\exception.py", line 55, in inner
    response = get_response(request)

    return view_func(request, *args, **kwargs)
  File "C:\Users\mikha\issuetracker\base\views.py", line 68, in createRoom
    return render('room', pk=room.id)

Exception Type: AttributeError at /create-room/
Exception Value: 'function' object has no attribute 'id'

问题原因及修复方案 #

1. 变量未定义：调用 Room.objects.create() 时没有将创建的实例赋值给 room 变量，后续引用 room.id 时，room 实际指向了同名的视图函数，导致报错。
2. render用法错误：重定向到详情页应该用 redirect 而非 render，render 用于渲染模板，redirect 才是跳转视图的正确方式。

修复后的代码：

from django.shortcuts import render, redirect  # 确保导入redirect

@login_required(login_url='login')
def createRoom(request):
    form = RoomForm()
    topics = Topic.objects.all()
    if request.method == 'POST':
        topic_name = request.POST.get('topic')
        topic, created = Topic.objects.get_or_create(name=topic_name)

        # 将创建的Room实例赋值给room变量
        room = Room.objects.create(
            host=request.user,
            topic=topic,
            name=request.POST.get('name'),
            assigned=request.user,
            status=request.POST.get('status'),
            priority=request.POST.get('priority'),
            type=request.POST.get('type'),
            description=request.POST.get('description'),
        )
        # 使用redirect跳转到room详情视图
        return redirect('room', pk=room.id)

    # 移除未定义的room变量，避免GET请求时报错
    context = {'form': form, 'topics': topics}
    return render(request, 'room/room_form.html', context)

额外说明：

• 确保项目URL配置中存在名为'room'的路由，且该路由对应接收pk参数的详情视图。
