Django 表单向导 'NoneType' 对象没有属性 'rsplit' 错误
Django form wizard 'NoneType' object has no attribute 'rsplit' error
您好,希望有人能提供帮助,我一直在为一个项目试用表单向导,并一直在密切关注文档,但不断收到此错误:
'NoneType' object has no attribute 'rsplit'
forms.py:
from django import forms
class ContactForm1(forms.Form):
subject = forms.CharField()
sender = forms.CharField()
class ContactForm2(forms.Form):
message = forms.CharField()
views.py:
class ContactWizard(WizardView):
def done(self, form_list, **kwargs):
return render_to_response('done.html', {
'form_data': [form.cleaned_data for form in form_list],
})
和urls.py(astapp是'woo')
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^woo/', ContactWizard.as_view([ContactForm1, ContactForm2]))
]

每当我去 woo/ url 它只显示非类型错误拆分。我试过重做整个事情,但仍然遇到同样的错误。希望有人能帮忙。
不要子类化 WizardView
,尝试子类化 SessionWizardView
:
from formtools.wizard.views import SessionWizardView
class ContactWizard(SessionWizardView):
...
文档对此不是很清楚,但在大多数情况下,您不应该直接子类化 WizardView
- 相反,您应该使用许多子视图:
SessionWizardView
CookieWizardView
NamedUrlWizardView
等
