Question

这是我通过关注this和this

制作的FormWizard

views.py

from django.shortcuts import render
from django.template import RequestContext
from django.http import HttpResponseRedirect
from formtools.wizard.views import SessionWizardView

# Create your views here.
def index(request):
    return render(request, 'wizardApp/index.html')

class ContactWizard(SessionWizardView):
    template_name = "wizardApp/contact_form.html"
    def done(self, form_list, **kwargs):
        process_form_data(form_list)
        return HttpResponseRedirect('../home')

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

    print(form_data[0]['subject'])
    print(form_data[0]['info1'])
    print(form_data[0]['info2'])
    print(form_data[1]['sender'])
    print(form_data[1]['info1'])
    print(form_data[1]['info2'])
    print(form_data[2]['message'])
    print(form_data[2]['info1'])
    print(form_data[2]['info2'])

    return form_data

urls.py

from django.conf.urls import url
from wizardApp import views

from wizardApp.forms import ContactForm1, ContactForm2, ContactForm3
from wizardApp.views import ContactWizard

app_name = 'wizardApp'

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^home/$', views.index, name='index'),
    url(r'^admin/', admin.site.urls),
    url(r'^contact/$', ContactWizard.as_view([ContactForm1, ContactForm2, ContactForm3])),
]

forms.py

from django import forms

class ContactForm1(forms.Form):
    subject = forms.CharField(max_length=100)
    info1 = forms.CharField(max_length=100)
    info2 = forms.CharField(max_length=100)

class ContactForm2(forms.Form):
    sender = forms.EmailField()
    info1 = forms.CharField(max_length=100)
    info2 = forms.CharField(max_length=100)

class ContactForm3(forms.Form):
    info1 = forms.CharField(max_length=100)
    info2 = forms.CharField(max_length=100)
    message = forms.CharField(widget=forms.Textarea)

contact_form.html

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8">
        <title></title>
        {{ wizard.form.media }}
    </head>
<body>

<p>Step {{ wizard.steps.step1 }} of {{ wizard.steps.count }}</p>

<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</button>
    {% endif %}
    <input type="submit" value="submit"/>
  </form>

  </body>
</html>

我在理解如何自定义表单的每个步骤时遇到了很多麻烦。不幸的是，对此有很少的帮助。我看到this关于创建多个模板的帖子和那种帮助，但我的主要缺点是如何创建这些模板以及如何在每个步骤中实现它们。

以正常形式我可以做这样的事情

<form novalidate="novalidate" autocomplete="on" method="POST">
            {% csrf_token %}

            <div class="form-horizontal">
              <div class="form-left">
                {{form.first_name}}
                {{form.first_name.errors}}
              </div>
              <div class="form-right">
                {{form.last_name}}
                {{form.last_name.errors}}
              </div>
            </div>
            <div>
              {{form.email}}
              {{form.email.errors}}
            </div>

            <div>
              <input type="submit" value="Submit">
            </div>

        </form>

我如何访问每个字段？我可以在哪里添加html和其他位来帮助一般样式？我应该如何为每个步骤制作其中一个？我应该将html和所有内容复制并粘贴到其他“模板”中吗？如何为每个步骤调用每个模板？

谢谢！

希望你明白这一点。为了遇到这个问题的人，这就是我解决这个问题的方法。我将{{ wizard.form }}替换为for循环以手动呈现输入：

<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 %}
        {% for field in wizard.form %}
            <label for="{{ field.id_for_label }}">{{ field.label }}</label>
            {{ field }}
            <span class="message">{{ field.errors }}</span>
        {% endfor %}
{% 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</button>
{% endif %}
<input type="submit" value="submit"/>

您可以为每个表单创建一个模板，然后将其与docs中所述的相应表单相关联，或者如果您希望每个表单使用相同的模板，您只需设置ContactWizard类中的template_name属性：

class ContactWizard(SessionWizardView):
    template_name = "contact_form.html"
