我正在尝试为我的Django网站创建一个联系表单，但它无法正常工作。联系表格有三个步骤。第1步有一个框，您可以在其中输入电子邮件的主题。第2步有一个框，您可以在其中输入发件人的电子邮件地址。此时，有三个按钮 - ＆＃34;第一步＆＃34;，＆＃34;上一步＆＃34;和＆＃34;提交＆＃34;。如果我点击＆＃34;提交＆＃34;，该网站不会将我带到第3步，这应该是您输入电子邮件正文的地方。相反，它将我重新回到第1步页面。
我做了我的研究，但我无法找到与此特定问题相关的在线内容。
这是我的views.py文件，它位于django_test / django_test目录中：
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.contrib import auth
from django.core.context_processors import csrf
from forms import MyRegistrationForm
from django.contrib.formtools.wizard.views import SessionWizardView
from django.core.mail import send_mail
from django.core.urlresolvers import reverse
#import logging
#logr = logging.getLogger(__name__)
def login(request):
c = {}
c.update(csrf(request))
return render_to_response('login.html', c)
def auth_view(request):
username = request.POST.get('username', '')
password = request.POST.get('password', '')
user = auth.authenticate(username=username, password=password)
if user is not None:
auth.login(request, user)
return HttpResponseRedirect('/accounts/loggedin')
else:
return HttpResponseRedirect('/accounts/invalid')
def loggedin(request):
return render_to_response('loggedin.html',
{'full_name': request.user.username})
def invalid_login(request):
return render_to_response('invalid_login.html')
def logout(request):
auth.logout(request)
return render_to_response('logout.html')
def register_user(request):
if request.method == 'POST':
form = MyRegistrationForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/accounts/register_success')
args = {}
args.update(csrf(request))
args['form'] = MyRegistrationForm()
return render_to_response('register.html', args)
def register_success(request):
return render_to_response('register_success.html')
class ContactWizard(SessionWizardView):
template_name = "contact_form.html"
def done(self, form_list, **kwargs):
form_data = process_form_data(form_list)
return render_to_response('done.html', {'form_data': form_data})
def process_form_data(form_list):
form_data = [form.cleaned_data for form in form_list]
logr.debug(form_data[0]['subject'])
logr.debug(form_data[1]['sender'])
logr.debug(form_data[2]['message'])
send_mail(form_data[0]['subject'],
form_data[2]['message'], form_data[1]['sender'],
[(my email address], fail_silently=False)
return form_data
这是我的forms.py文件，也位于django_test / django_test目录中：
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
class MyRegistrationForm(UserCreationForm):
email = forms.EmailField(required=True)
class Meta:
model = User
fields = ('username', 'email', 'password1', 'password2')
def save(self, commit=True):
user = super(UserCreationForm, self).save(commit=False)
user.email = self.cleaned_data['email']
if commit:
user.save()
return user
class ContactForm1(forms.Form):
subject = forms.CharField(max_length=100)
class ContactForm2(forms.Form):
sender = forms.EmailField()
class ContactForm3(forms.Form):
message = forms.CharField(widget=forms.Textarea)
我的contact_form.html文件，位于django_test / templates目录中：
{% extends "base.html" %}
{% block content %}
<h2>Contact Us</h2>
<p>Step {{ wizard.steps.step1 }} of {{ wizard.steps.count }}</p>
{% for field in form %}
{{field.error}}
{% endfor %}
<form action="/contact/" method="post">{% csrf_token %}
<table>
{{ wizard.management_form }}
{% if wizard.form.forms %}
{{ wizard.form.management_form }}
{% for form in wizard.form.forms %}
{{ form }}
{% endfor %}
{% else %}
{{ wizard.form }}
{% endif %}
</table>
{% if wizard.steps.prev %}
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.first }}">"first step"</button>
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">"prev step"</buttom>
{% endif %}
<input type="submit" value="submit" />
</form>
{% endblock %}
这是我的urls.py文件：
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
from django_test.api import ArticleResource
from django_test.forms import ContactForm1, ContactForm2, ContactForm3
from django_test.views import ContactWizard
article_resource = ArticleResource()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^accounts/login/$', 'django_test.views.login'),
url(r'^accounts/auth/$', 'django_test.views.auth_view'),
url(r'^accounts/loggedin/$', 'django_test.views.loggedin'),
url(r'^accounts/invalid/$', 'django_test.views.invalid_login'),
url(r'^accounts/logout/$', 'django_test.views.logout'),
url(r'^accounts/register/$', 'django_test.views.register_user'),
url(r'^accounts/register_success/$', 'django_test.views.register_success'),
url(r'^articles/all/$', 'article.views.articles'),
url(r'^articles/create/$', 'article.views.create'),
url(r'^articles/get/(?P<article_id>\d+)/$', 'article.views.article'),
url(r'^articles/like/(?P<article_id>\d+)/$', 'article.views.like_article'),
url(r'^articles/add_comment/(?P<article_id>\d+)/$', 'article.views.add_comment'),
url(r'^articles/search/', 'article.views.search_titles'),
url(r'^articles/api/', include(article_resource.urls)),
url(r'^contact/', ContactWizard.as_view([ContactForm1, ContactForm2, ContactForm3])),
)
我也没有收到任何错误消息，这令人沮丧，因此我不知道自己做错了什么。谢谢。
答案 0 :(得分：1)
我所要做的就是查看网站上的页面来源。事实证明
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">"prev step"</buttom>
有一个拼写错误：</buttom>。我修复了错误，现在我得到了评论页面。
该行应为：
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">"prev step"</button>
