Django的formtools向导生成空白页（没有错误返回）

Question

我试图使用formtools包没有成功的formwizard（我能做到这一点时，包在里面的Django在早期版本）。

我得到的唯一回应是：

[23/Jan/2016 11:06:50]"GET /registration/wizard HTTP/1.1" 200 13729 

和一个空白页。在浏览器或Eclipse控制台没有错误。

有没有没有错误谷歌搜索的方式。请帮忙。

在此先感谢

我做了什么？

首先，我安装formtools包与PIP：

django-formtools==1.0 
Django==1.8.3 

继官方的文档的指令：

1. 定义表单类

   登记/ forms.py

   class StepForm1(forms.Form): 
       first_field = forms.CharField(max_length=100) 
       second_field = forms.CharField() 
   
   class StepForm2(forms.Form): 
       message = forms.CharField(widget=forms.Textarea) 
   

2. 创建WizardView

   登记/ views.py

   TEST_TEMPLATES = {"test_step_1": "registration/test_step1.html", "test_step_2": "registration/test_step2.html", } 
   
   from formtools.wizard.views import SessionWizardView 
   
   class WizardTest(SessionWizardView): 
       template_name = 'registration/test_wizard.html' 
   
       # Return templates for each step 
       def get_templates_name(self): 
        return [TEST_TEMPLATES[self.steps.current]] 
   
       # Method called when all is done 
       def done(self, form_list, **kwargs): 
   
        # return HttpResponseRedirect('/url-to-redirect-to/') 
   
        # We return the final template with the info 
        return render_to_response('test_done.html', { 
               'form_data':[form.cleaned_data for form in form_list], 
               }) 
   
       # THESE METHODS BELOW ARE NOT NEEDED, BUT COMMENTED FOR FUTURE USE 
   
       # Not strictly needed. Returns data for a step 
       # or None if form is not valid 
       # def get_cleaned_data_for_step(self, step): 
       #  return None 
   
       # Form data postprocessing in a concrete wizard step 
       # def process_step(self, form): 
       #  return self.get_form_step_data(form) 
   
       # Handles value from a step before storing them into wizard 
       # def get_form_step_data(self, form): 
       #  return form.data 
   

3. 创建模板

   登记/ test_step1.html

   <h1>Two fields form</h1> 
   <input id="first_field" name="first_field"> 
   <input id="second_field" name="second_field"> 
   

   注册/ test_step2.html

   <h1>Message form</h1> 
   <input id="message" name="message"> 
   

   注册/ test_wizard.html

   {% extends "person/alumnos.html" %} 
   {% load i18n %} 
   
   {% block head %} 
       {{ wizard.form.media }} 
   {% endblock head %} 
   
   {% block content %} 
   <p>{% trans "Step {{wizard.steps.step1}} of {{wizard.steps.count}}" %}</p> 
   
   <form action="" method="post"> 
   {% csrf_token %} 
   
   {{ wizard.management_form }} 
   
   {% if wizard.form.forms %} 
       {{ wizard.form.management_form }} 
       {% for form in wizard.form.forms %} 
        {{form}} 
       {% endfor %} 
   {% else %} 
       {{ wizard.form }} 
   {% endif %} 
   
   {% if wizard.steps.prev %} 
   <button name="wizard_goto_step" type="submit" value="{{ wizard.steps.first }}">{% trans "Beginning" %}</button> 
   <button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">{% trans "Previous step" %}</button> 
   {% endif %} 
   <input type="submit" value="submit"/> 
   
   </form> 
   
   {% endblock %} 
   

4. 增加 'formtools' 我INSTALLED_APPS

   settings.py

   DJANGO_APPS = (
       # Default Django apps: 
       'django.contrib.auth', 
       'django.contrib.contenttypes', 
       'django.contrib.sessions', 
       'django.contrib.sites', 
       'django.contrib.messages', 
       'django.contrib.staticfiles', 
       'formtools',     # <===== HERE 
   
       # Useful template tags: 
       # 'django.contrib.humanize', 
   
       # Admin panel and documentation: 
       'django.contrib.admin', 
       # 'django.contrib.admindocs', 
   ) 
   
   # Apps specific for this project go here. 
   LOCAL_APPS = (
       'person', 
       'registration', 
       'teaching', 
       'utils', 
   ) 
   
   # See: https://docs.djangoproject.com/en/dev/ref/settings/#installed-apps 
   INSTALLED_APPS = DJANGO_APPS + LOCAL_APPS 
   

5. 点我的URLconf你WizardView as_view（）方法。

登记/ urls.py

from registration.forms import StepForm1, StepForm2 
TEST_FORMS = [("test_step_1", StepForm1), ("test_step_2", StepForm2), ] 

from registration.views import WizardTest 

# I tried in two ways, none of them worked 

urlpatterns = patterns('', 
     url(r'^wizard$', WizardTest.as_view(TEST_FORMS), name='wizard_test'), 
     url(r'^wizard2$', views.wizard, name='wizard_test'), 
) 

对于第二种方式...

注册/ views.py

def wizard(request): 
    return WizardTest.as_view(TEST_FORMS)(request) 

Answer 1

我发现我的错误。我输入了获取模板的方法名称。这不是

get_templates_name(self) 

但

get_template_names(self) 

它没有得到任何模板，但返回到服务器时，它与HTTP 200 OK应答，因为它没有发现任何错误。

我还发现，我的每一步的模板应该以正常工作延长主向导模板。 “完成”模板不是必需的。

Answer 2

你下你的模板有什么例子？ The basic layout is in the docs。试着像这样的东西开始（这两个页面可以使用相同的模板，如果你的罚款与formtools产生的场）：

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Form Wizard</title> 
    {{ wizard.form.media }} 

</head> 
<body> 
{% load i18n %} 
<p>Step {{ wizard.steps.step1 }} of {{ wizard.steps.count }}</p> 
<form action="" 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 }}">{% trans "first step" %}</button> 
<button name="wizard_goto_step" type="submit" value="{{ wizard.steps.prev }}">{% trans "prev step" %}</button> 
{% endif %} 
<input type="submit" name="submit" value="{% trans "submit" %}"/> 
</form> 
</body> 
</html>
