Django的煩惱與形式和CSRF令牌

Question

我試圖得到一個非常簡單的電子郵件的形式工作。表格只有一個字段（電子郵件）。

forms.py

from django import forms 

class EmailForm(forms.Form): 
    email = forms.EmailField() 

views.py

from django.shortcuts import render_to_response 
from django.core.mail import EmailMultiAlternatives 
from django.template import RequestContext 
from launchpage.models import EmailForm 

def index(request): 
    if request.method == 'POST':   
     form = EmailForm(request.POST) 
     if form.is_valid(): 
      clean_data = form.clean_data 
      # send an email 
        thank_you = "Thanks for signing up" 
      return render_to_response('launch.html', {'thank_you': thank_you}) 
    else: 
     form = EmailForm() 
    return render_to_response('launch.html', {'form': form,}, context_instance=RequestContext(request)) 

launch.html（相關部分）

<div class="row-fluid"> 
    <div class="span12"> 
     {% if thank_you %} 
      <div class="alert alter-info"> 
      {{ thank_you }} 
      </div> 
     {% else %} 
      <form action="" method="post" class="form-horizontal">{% csrf_token %} 
      Or stay updated by email (no spam, pinky swear) &nbsp;&nbsp; 
      {{ form.email }} 
      <button type="submit" class="btn">Submit</button> 
     </form> 
     {% endif %} 
    </div> 
</div> 

中間件在settings.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware', 
    'django.contrib.sessions.middleware.SessionMiddleware', 
    'django.middleware.csrf.CsrfViewMiddleware', 
    'django.contrib.auth.middleware.AuthenticationMiddleware', 
    'django.contrib.messages.middleware.MessageMiddleware', 
) 

---

當前的結果：頁面顯示出來，就像沒有涉及模板。我看到表單和提交按鈕在那裏，但沒有電子郵件字段。也沒有csrf隱藏字段。我一定是失去了一些東西愚蠢......

Answer 1

假設這個：

from launchpage.models import EmailForm

不應該from launchpage.forms import EmailForm

你有另一個問題是{'form': form,}需求是{'form': form}

最後，{{ form.email }}應該是簡單的{{ form }}

最終尖端 - 考慮使用可自動發送相應的請求上下文的render shortcut。
