Django - WSGIRequest' object has no attribute 'Get'

Question

So I have 2 scenerios in which one works and one doesnt. I set up a select box in the html template with some hard coded options which you can see in Scenrio2. Im curious to know why Scenario2 works with no problems and Scenario1 throws this error. I have also attached the stack trace below.

Scenario1(Doesnt Work):

    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')

Scenario 2(works):

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')

It has nothing to do with the approach you followed. In your first approach you write:

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

Like the error says, the request object has no Get attribute, only a GET attribute. You make the same mistake over the rest of the view.

So you can fix this with:

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

You furthermore also wrote parent_req__username=request.user in the filtering (of both views), I think it might be better to use parent_req=request.user, or parent_req__username=request.user.username).

You can in fact improve this a bit further like:

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'
    )
