title: How do I enable recurring payment in django-paypal?
body: <p>I installed django-paypal, and I'm trying to enable subscription button.</p>
  
  <p>I have the following view.</p>
  
  <pre><code>def donate_root(request):
      paypal_dict = {
          "business": PAYPAL_RECEIVER_EMAIL,
          "amount": "10.00",
          "item_name": "foobar money",
          'currency_code': 'USD',
          "invoice": "unique-invoice-id",
          "notify_url": "https://www.example.com" + reverse('paypal-ipn'),
          "return_url": "https://www.example.com/your-return-location/",
          "cancel_return": "https://www.example.com/your-cancel-location/",
          't3': 'D',
          'p3': '1',
  
      }
      form = PayPalPaymentsForm(initial=paypal_dict)
      context = {"form": form}
      return render_to_response("main.html", context)
  </code></pre>
  
  <p>In main.html I have the following inside a div</p>
  
  <pre><code>{{ form.render }}
  </code></pre>
  
  <p>When I click the link, it takes me to paypal page that take the money once, and not recurring payment. </p>
  
  <p>What did I do wrong?</p>
