Django-WSGIRequest'對象沒有屬性'Get'

Question

因此，我有2個場景，其中一個有效，而一個無效。 我在html模板中設置了一個選擇框，其中包含一些在Scenrio2中可以看到的硬編碼選項。 我很想知道為什么Scenario2可以正常工作，而Scenario1會引發此錯誤。 我還附加了下面的堆棧跟蹤。

方案1（不工作）：

    current_status = 'All'
    status_list = []

    all_status = RequisitionStatus.objects.all()
    for status in all_status:
        status_list.append(status.status)

    if request.Get.get('Filter') in status_list:
        user_req_lines_incomplete = RequisitionLine.objects.filter(Q(parent_req__username=request.user) & Q(status__status=request.Get.get('Filter')))
        current_status = request.Get.get('Filter')
    else:
        user_req_lines_incomplete = RequisitionLine.objects.filter(parent_req__username=request.user).exclude(status__status='Completed')

方案2（可行）：

if request.GET.get('Filter') == 'Created':
        user_req_lines_incomplete = RequisitionLine.objects.filter(Q(parent_req__username=request.user) & Q(status__status='Created'))
        current_status = 'Created'
    elif request.GET.get('Filter') == 'For Assistance':
        user_req_lines_incomplete = RequisitionLine.objects.filter(Q(parent_req__username=request.user) & Q(status__status='For Assistance'))
        current_status = 'For Assistance'
    elif request.GET.get('Filter') == 'Assistance Complete':
        user_req_lines_incomplete = RequisitionLine.objects.filter(Q(parent_req__username=request.user) & Q(status__status='Assistance Complete'))
        current_status = 'Assistance Complete'
    elif request.GET.get('Filter') == 'Assistance Rejected':
        user_req_lines_incomplete = RequisitionLine.objects.filter(Q(parent_req__username=request.user) & Q(status__status='Assistance Rejected'))
        current_status = 'Assistance Rejected'
    else:
        user_req_lines_incomplete = RequisitionLine.objects.filter(parent_req__username=request.user).exclude(status__status='Completed')

Answer 1

它與您遵循的方法無關。 在第一種方法中，您將編寫：

if request.Get.get('Filter') in status_list:
  # ...

就像錯誤所說的一樣， request對象沒有Get屬性，只有GET屬性。 您在其余視圖中也會犯同樣的錯誤。

因此，您可以使用以下方法解決此問題：

if request.GET.get('Filter') in status_list:
  # ...

您還進一步在過濾（兩個視圖）中都寫了parent_req__username=request.user ，我認為最好使用parent_req=request.user或parent_req__username=request.user.username ）。

實際上，您可以進一步改善它，例如：

current_status = 'All'
all_status = RequisitionStatus.objects.values_list('status', flat=True)
filter = request.GET.get('filter')

if filter in status_list:
    user_req_lines_incomplete = RequisitionLine.objects.filter(
        parent_req=request.user,
        status__status=filter
    )
    current_status = filter
else:
    user_req_lines_incomplete = RequisitionLine.objects.filter(
        parent_req=request.user
    ).exclude(
        status__status='Completed'
    )
