I am working on an old open source app, and I keep on getting the following error every time I try to add a new invoice instance:
AttributeError at /admin/invoices/invoiceheaders/add/ 'tuple' object has no attribute 'startswith'
I am working with two (2) modules: views.py and models.py:
views.py

customer = Contacts.objects.get(id = int(request.POST['Custumer']) )

ihd = InvoiceHeaders()
ihd.user = user
ihd.issuer = issuer
ihd.payterm = payterm

ihd.status = 'D'
ihd.findrandomnumber=sha224( "%f"%(time()) ).hexdigest()
ihd.save()
for id in range(1, int(request.POST['numberitem']) + 1):

ibd.header = ihd
ibd.quantity = float(request.POST['Item_qta_%s' %id].replace(',','.'))

ibd.extraDescription = request.POST['Item_descr_%s' %id].strip()

答案 0 :(得分：5)
MEDIA_ROOT应为字符串，您正在创建一个tupple。
在settings.py 中您正在添加＆＃39;，＆＃39;逗号， 删除它来解决问题。 它正在创建一个tupple，我们需要一个String。
MEDIA_ROOT = '%s/media' %PROJECT_PATH,
将此更改为
MEDIA_ROOT = '%s/media' %PROJECT_PATH
它将解决问题。
