类acroniform（forms.ModelForm）：
def clean_key(self):
Key = self.cleaned_data['Key']
if Acronis.objects.filter(Key_iexact=Key).exists():
raise forms.ValidationError('Dieser Key ist bereits vergeben')
return Key
class Meta:
model = Acronis

如何停止复制？我也尝试过“ update_or_create” ...
@login_required()
def edit_acronis(request, id):
item = get_object_or_404(Acronis, id=id)
if request.method == "POST":
form = acroniform(request.POST, instance=item)
if form.is_valid():
form = acroniform.save(commit=True)
form.save()
return redirect('/Verwaltung/Acronis')
else:
form = acroniform(instance=item)
return render(request, 'blog/editacronis.html', {'form': form})
所以“ commit = True以及commit = False”不起作用。它仍然在重复...
