我有一个未保存到数据库的自定义表单。我没有收到任何错误，但值没有保存到数据库中。有任何想法吗？
视图.py
def diseasestateoption(request, disease_id, state_id):
state = get_object_or_404(State, pk=state_id)
disease = get_object_or_404(Disease, pk=disease_id)
if request.method == "POST":
form = UpdateStateWithOptionsForm(request.POST, instance=state)
if form.is_valid():
for option_id in request.POST.getlist('options'):
state_option = StateOption.objects.create(partstate=state, partoption_id=int(option_id))
state_option.save()
return HttpResponseRedirect(reverse('success'))
else:
form = UpdateStateWithOptionsForm(instance=state)
模型.py
class Option(models.Model):
relevantdisease = models.ForeignKey(Disease)
option = models.CharField(max_length=300)
class State(models.Model):
state = models.CharField(max_length=300, verbose_name='state')
relevantdisease = models.ForeignKey(Disease, verbose_name="disease")
relevantoption = models.ManyToManyField(Option, through='StateOption')
class StateOption(models.Model):
parttstate = models.ForeignKey(State)
partoption = models.ForeignKey(Option)
表格.py
class UpdateStateWithOptionsForm(forms.ModelForm):
class Meta:
model = State
exclude = ['state', 'relevantdisease']
def __init__(self, *args, **kwargs):
super(UpdateStateWithOptionsForm, self).__init__(*args, **kwargs)
self.fields['relevantoption']=forms.ModelMultipleChoiceField(queryset=Option.objects.all(),required=True, widget=forms.CheckboxSelectMultiple)
