注册表包含多个ContactForm和FeeForm，我尝试验证FeeForm，注册表中存在的ContactForms，验证失败并且没有显示任何验证错误，对于空的FeeForm字段，联系表单
forms.py
class ContactForm(forms.Form):
address = forms.CharField(widget = forms.Textarea(attrs = {'rows' : '5'}),required = False)

date= forms.DateField(required = True)
amount = forms.CharField(required=True)
def clean_amount(self):
amount = self.cleaned_data['amount']
if amount == '':
self._errors["amount"] = ["Please Enter Amount"]
return amount
class RegistrationForm(forms.Form):
hall_ticket_number = forms.CharField(required = False)
name = forms.CharField(required=True)
religion = forms.CharField(required = False)
present_contact = ContactForm()
gender = forms.ChoiceField( choices = ( ('M', 'Male'), ('F', 'Female')),required = True)
organization_contact = ContactForm()
fee_details = FeeForm()

return amount

每个单独的表单都需要调用自己的form.is_valid()来获取模板中的错误字段。在您的post方法中，只有一个form.is_valid(}被调用，仅用于RegistrationForm。更独立地发送/接收三个表单。在模板中，在一个表单下使用它们。
事情可以通过这种方式完成：
views.py
if request.method == 'POST':
reg_form = RegistrationForm(request.POST)
contact_form = ContactForm(request.POST)
free_form = FeeForm(request.POST)
reg_valid = reg_form.is_valid()
contact_valid = contact_form.is_valid()
free_valid = free_form .is_valid()
if reg_valid and contact_valid and free_valid:
#Everything is fine, do the registration and go to success page
else:
#error happened, so go to form page with error fields
return render(request, 'registration/register.html', {'student' : student, 'reg_form' : reg_form,'contact_form' : contact_form, 'free_form' : free_form,'registration_status' : registration_status,'registration':registration })
else:
reg_form = RegistrationForm(initials=...)
contact_form = ContactForm(initials=...)
free_form = FeeForm(initials=...)
return render(request, 'registration/register.html', {'student' : student, 'reg_form' : reg_form,'contact_form' : contact_form, 'free_form' : free_form,'registration_status' : registration_status,'registration':registration })
