django models请求获取id错误房间匹配查询不存在

Question

我有两个模型，当我要求的时候。POST. get（'room_id'）或（'id'）我得到一个错误房间匹配查询不存在.如何解决这个问题？帮我一把

    class Room(models.Model):
        status = models.BooleanField('Status',default=True)
        name = models.CharField('Name', max_length=100, unique=True)

    class Book(models.Model):
        date = models.DateTimeField('Created',auto_now_add=True)
        from_date = models.DateField('Check-in')
        to_date = models.DateField('Check-out')
        room = models.ForeignKey(Room, related_name='booking')

我需要详细的房间请求获取id，预订日期范围（从\u日期到\u日期）

def room_detail(request,pk):
    room = get_object_or_404(Room,pk=pk)
    if request.method == 'POST':
        form = BookForm(request.POST,room=room)
        if form.is_valid():
            s = form.save(commit=True)          
            s.save()
            return redirect(request.path)
    else:
        form = BookForm()

    #roomid = Room.objects.values('id')
    type = request.POST.get('id') # or get('room_id')
    rooms = Room.objects.get(id=type)

    start_dates = rooms.booking.values_list('from_date',flat=True)
    end_dates = rooms.booking.values_list('to_date',flat=True)
    dates = [start + timedelta(days=i) for start, end in zip(start_dates,end_dates) for i in range((end-start).days+1)]

    c = {}
    c['form'] = form
    return render_to_response('rooms_detail.html',c)

请帮助我，提前谢谢

if request.method == 'POST':
    form = BookForm(request.POST,room=room)
    if form.is_valid():
        type = request.POST.get('id')
        rooms = Room.objects.get(id=type)
        object = form.save(commit=True)          
        object.save()
        return redirect(request.path)

Answer 2

您正在查看request.POST，即使request.method不等于'POST'。这将不起作用，因为当请求不是HTTP post时，请求的post成员为空。

Answer 3

移动你的线路

#roomid = Room.objects.values('id')
type = request.POST.get('id') # or get('room_id')
rooms = Room.objects.get(id=type)

在post方法内部。

if request.method == 'POST':
    form = BookForm(request.POST,room=room)
    if form.is_valid():
        #roomid = Room.objects.values('id')
        type = request.POST.get('id') # or get('room_id')
        rooms = Room.objects.get(id=type)
        s = form.save(commit=True)          
        s.save()
        return redirect(request.path)
