我有一个使用django表单向导的sessionwizardview构建的多步表单，我已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，当我单击上一个时，它会询问首先填写表单，然后单击上一个按钮继续前进。我无能为力，因为我无法找到与我的问题有关的任何事情，我错过了什么？
以下是几种示例表单：
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：

也许会帮助别人。
我正在使用带有引导程序的https://django-formtools.readthedocs.io/en/latest/wizard.html和Django。我遇到了与OP相同的问题，但是我没有活动的JS。就我而言，解决方案是在模板中添加 formnovalidate =“ formnovalidate” 。
{% if wizard.steps.prev %}
<button formnovalidate="formnovalidate" name="wizard_goto_step" value="{{ wizard.steps.first }}">
first step
</button>
<button formnovalidate="formnovalidate" name="wizard_goto_step" value="{{ wizard.steps.prev }}">
prev step
</button> {% endif %}
希望有帮助。

HTML5包含formnovalidate attribute，可用于跳过验证。对于“表单向导”，要跳过上一步的验证，只需将formnovalidate属性包括在相应的按钮中即可。例如（摘录自documentation的片段）：
<form action="" method="post">{% csrf_token %}
<table>
{{ wizard.form }}
</table>
{% if wizard.steps.prev %}
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.first }}">{% trans "first step" %}</button>
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}" formnovalidate>{% trans "prev step" %}</button>
{% endif %}
<input type="submit" value="{% trans "submit" %}"/>
</form>
