【问题描述】：

我正在尝试根据django docs 为简单的联系表单创建自定义模板，但我得到了NameError。看起来像一个简单的问题，但我无法弄清楚。任何帮助将不胜感激。错误信息是：

"NameError at /contact/
name 'wizardcustomtemplate' is not defined"

'wizardcustomtemplate' 是应用程序。这是我的代码：

urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

from wizardcustomtemplate.forms import SubjectForm, SenderForm, MessageForm
from wizardcustomtemplate.views import ContactWizard

urlpatterns = patterns('',
                       url(r'^admin/', include(admin.site.urls)),
                       url(r'^contact/$', ContactWizard.as_view(FORMS)),
)

views.py

import os
from django.shortcuts import render
from django.shortcuts import render_to_response
from django.http import HttpResponse
from django.http import HttpResponseRedirect
from django.core.mail import send_mail
from django.core.context_processors import csrf
from django.contrib.formtools.wizard.views import SessionWizardView
from django.contrib.formtools.wizard.views import WizardView
from django.core.files.storage import FileSystemStorage
from django.core.files import File

FORMS = [("0", wizardcustomtemplate.forms.SubjectForm),
("1", wizardcustomtemplate.forms.SenderForm),
("2", wizardcustomtemplate.forms.MessageForm)
]

TEMPLATES = "0": "wizardcustomtemplate/subject.html",
"1": "wizardcustomtemplate/sender.html",
"2": "wizardcustomtemplate/message.html"


class ContactWizard(SessionWizardView):
    def get_template_names(self):
        return [TEMPLATES[self.steps.current]]

    def done(self, form_list, **kwargs):
        form_data = process_form_data(form_list)
        return render_to_response('wizardcustomtemplate/thanks.html', 'form_data': form_data)

def process_form_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    return form_data

forms.py

from django import forms

class SubjectForm(forms.Form):
    subject = forms.CharField(max_length = 100,initial='Wizard')

class SenderForm(forms.Form):
    sender = forms.EmailField(initial='[e-mail]')

class MessageForm(forms.Form):
    message = forms.CharField(initial='How r u?')

如果我不使用自定义模板（FORMS、TEMPLATES 等），表单向导可以正常工作。如果您需要更多信息，请告诉我。

【问题讨论】：

我认为您需要在 views.py

中添加import wizardcustomtemplate

谢谢罗汉。成功了！！

【参考方案1】：

按照@Rohan 的建议在views.py 中添加import wizardcustomtemplate 解决了这个问题。
