我在Python和Django的相对较新的多个值,Django的类型错误:get()方法得到了关键字参数 'INVOICE_ID'
我有以下REST API观点,
class InvoiceDownloadApiView(RetrieveAPIView):
"""
This API view will retrieve and send Terms and Condition file for download
"""
permission_classes = (IsAuthenticated,)
def get(self, invoice_id, *args, **kwargs):
if self.request.user.is_authenticated():
try:
invoice = InvoiceService(user=self.request.user, organization=self.request.organization).invoice_download(
invoice_id=invoice_id)
except ObjectDoesNotExist as e:
return Response(e.message, status=status.HTTP_404_NOT_FOUND)
if invoice:
response = HttpResponse(
invoice, content_type='application/pdf')
response['Content-Disposition'] = 'inline; filename={0}'.format(
invoice.name.split('/')[-1])
response['X-Sendfile'] = smart_str(invoice)
return response
else:
return Response({"data": "Empty File"}, status=status.HTTP_400_BAD_REQUEST)
使用以下网址,
urlpatterns = [
url(r'^invoice/(?P<invoice_id>[0-9]+)/download/$', views.InvoiceDownloadApiView.as_view()),
]
根URL模式是如下,
url(r'^api/payments/', include('payments.rest_api.urls', namespace="payments")),
当我打电话终点,
localhost:8000/api/payments/invoice/2/download/
它出现以下错误,
TypeError at /api/payments/invoice/2/download/
get() got multiple values for keyword argument 'invoice_id'
无法弄清楚什么是真正造成这个错误
wi那个发票ID,我的数据库中只有一张发票。 – RTan
请添加'invoice_download'方法的实现,所以我们可以帮助你。 – AKS
@AKS不,这并不意味着。这将是一个MultipleObjectsReturned错误。 –
