我有一个具有多对多字段的模型。当我尝试保存它时，它会出错并出现invalid literal for int() with base 10: 'A'错误。从我读过的其他帖子来看，这似乎与我的 forms.py 中的 CharField 有关。在我的 clean_states 中，我可以打印值self.cleaned_data['states']并取回状态的两个字母代码。我认为这就是要保存到数据库中的内容。我不确定为什么它认为我正在尝试保存一个 int。
模型.py
class States(models.Model):
state = models.CharField(max_length=2, choices=US_STATES , null=True, blank=True)
def __str__(self):
return self.state
class Person(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
state = models.ManyToManyField(States)
视图.py
class UserProfileUpdateView(LoginRequiredMixin, UpdateView):
model = Person
form_class = UserProfileChangeForm
template_name = 'accounts/profile-update-view.html'
def get_context_data(self, *args, **kwargs):
context = super(UserProfileUpdateView, self).get_context_data(*args, **kwargs)
context['states'] = States.objects.all()
return context
def get_object(self):
qs = Person.objects.filter(pk=self.request.user.person.user_id).first()
return qs
表格.py
class UserProfileChangeForm(forms.ModelForm):
state= forms.CharField(widget=USStateSelect(), initial='TX')
class Meta:
model = SkilledLaborer
fields = ['user','state']
def clean_user(self):
user = self.cleaned_data['user']
return user
def clean_state(self):
state= self.cleaned_data['state']
return state
def save(self, *args, **kwargs):
print('im saving')
print(self.cleaned_data['states'])
obj = super(UserProfileChangeForm, self).save(*args, **kwargs)
print('here2')
add_states = self.cleaned_data['states']
print(add_states)
print('here3')
if add_states:
for state in add_states.split(","):
state = States.objects.get(state=state)
obj.states.add(state)
return obj
