Я пытаюсь напечатать отфильтрованное раскрывающееся раскрытие sub_location в соответствии с расширенной формой администратора в Django.
У меня есть представление, которое отображает форму и сохраняет ту же форму. Нет проблем с отображением представления, но при сохранении я получаю следующую ошибку:
Аргумент TypeError: int () должен быть строкой, байтовоподобным объектом или числом, а не QueryDict
Вот мой код: -
Модель:
class Location(models.Model):
name = models.CharField(max_length=30)
def __str__(self):
return self.name
class SubLocation(models.Model):
location = models.ForeignKey(Location, on_delete=models.CASCADE)
name = models.CharField(max_length=30)
def __str__(self):
return self.name
class AdminProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
location = models.ForeignKey(Location, on_delete=models.SET_NULL, null=True)
def __str__(self): # __unicode__ for Python 2
return self.user.username
class Batch(models.Model):
location = models.ForeignKey(Location, on_delete=models.SET_NULL, null=True)
sub_location = models.ForeignKey(SubLocation, on_delete=models.SET_NULL, null=True)
batch_name = models.CharField(max_length=30, unique=True)
def __str__(self):
return self.batch_name
FORM:
class BatchForm(forms.ModelForm):
class Meta:
model = Batch
fields = ('sub_location', 'batch_name')
def __init__(self, user, *args, **kwargs):
super(BatchForm, self).__init__(*args, **kwargs)
self.fields['sub_location'].queryset = SubLocation.objects.filter(location = Subquery(AdminProfile.objects.filter(user = user).values('location')))
ВИД:
def add_batch(request):
if request.user.is_authenticated:
msg = ""
if request.method == "GET":
batch_form = BatchForm(user=request.user)
else:
batch_form = BatchForm(request.POST, request.FILES)
if batch_form.is_valid():
try:
obj = batch_form.save(commit=False)
#logined admin location will be here
admin_object = AdminProfile.objects.filter(user = request.user)
obj.location = admin_object[0].location
obj.save()
batch_form = BatchForm()
msg = "Batch Added successfully....!"
except IntegrityError as e:
msg= "Batch already exist...!"
else:
batch_form = BatchForm(request.POST, request.FILES)
return render(request, 'add_new_batch.html', {'batch_form':batch_form,'msg':msg})
else:
return redirect('admin_login')
когда я нажимаю кнопку подтверждения, чтобы сохранить форму, я получаю эту ошибку
