我有一个使用 django 表单向导构建的多步骤表单sessionwizardview，我添加了下一个和上一个按钮，但问题是，如果我在一个步骤中并且当我单击上一个时，它会要求先填写表单然后可以继续并通过单击上一个按钮转到上一步。我一无所知，因为我找不到与我的问题相关的任何东西，我错过了什么吗？
以下是几个示例表格：
from django import forms
from django.utils.translation import gettext as _
from addresses.forms import AddressForm, InvoiceAddressForm
from core.api import NcpAPI
from django_countries import countries
api = NcpAPI()
CHOICES=[('0','Pay by card'), ('1','Invoice')]
class RegistrationForm(forms.Form):
title = 'registration'
first_name = forms.CharField(label=_("First Name"), widget=forms.TextInput(attrs={'class':'form-text required'}))
last_name = forms.CharField(label=_("Last Name"), widget=forms.TextInput(attrs={'class':'form-text required'}))
registration_company = forms.CharField(label=_("Company"), widget=forms.TextInput(attrs={'class':'form-text required'}))
phone = forms.CharField(label=_("Phone"), widget=forms.TextInput(attrs={'class':'form-text required'}))
email = forms.EmailField(label=_("Email"), widget=forms.TextInput(attrs={'class':'form-text required'}))
def clean_email(self):
email = self.cleaned_data.get('email')
if api.is_username_taken(email):
raise forms.ValidationError(_('Email is in use'))
return email
class AddressesForm(InvoiceAddressForm, AddressForm):
title = 'addresses'
class PaymentForm(forms.Form):
title = 'payment'
payment_method = forms.ChoiceField(label = _("Payment Options"), choices=CHOICES, widget=forms.RadioSelect(attrs={'class':'form-text required'}), required = True, initial = "1")
class ConfirmationForm(forms.Form):
title = 'confirm'
这是我的会话向导类：
