定制Django-PayPal视图

Question

我使用django paypal允许用户在我的网站上付款，但是我有一些疑问。

它目前对我的工作方式是，我有一个名为profile.html的模板。当用户单击“单击更多订阅选项”按钮时，他将被重定向到显示订阅表和贝宝按钮的subscriptions.html模板。单击按钮时，用户将被重定向到另一个名为paypal.html的模板，该模板显示从django- paypal的forms.py派生的另一个paypal按钮

我在这里的问题是如何修改贝宝视图，这样我就可以取消paypal.html，当用户点击subscription.html中的paypal按钮时，直接将用户引导到实际的paypal网站？

我希望我对这个问题的描述足够清楚。

在我的views.py：

def paypal(request):
    paypal_dict = {"business":settings.PAYPAL_RECEIVER_EMAIL,"amount": "1.00","item_name": "Milk" ,"invoice": "12345678", "notify_url": "%s%s" % (settings.SITE_NAME, reverse('paypal-ipn')),"return_url": "http://rosebud.mosuma.net",}
    # Create the instance.
    form = PayPalPaymentsForm(initial=paypal_dict)
    context = {"form": form.sandbox()}
    return render_to_response("paypal.html", context)

在我的profile.html：

....
<INPUT TYPE="submit" Value="Click to find out subscription plans" name="subscription" onClick="/subscribe/>

在我的subscription.html：

<form method="post" action="paypal/">
<select name="subscription_input" id="id_subscription" style = "float: center">
<option>Monthly</option>
<option>Yearly</option>
</select></br></br>

{{ form }}
</form>

在我的urls.py：

url(r'^paypal/$', 'r2.views.paypal', name='paypal'),
url(r'^profile/paypal/$', 'r2.views.paypal', name='paypal'),

如果您希望用户一单击PayPal中的PayPal按钮就直接访问subscription.html网站，您将不得不在subscription.html而不是paypal.html中呈现PayPal表单。此外，您需要在PayPalPaymentsForm中子类forms.py，以覆盖默认的PayPal映像"Buy“，因为您希望自己的按钮首先工作。

forms.py

from paypal.standard.forms import PayPalPaymentsForm
from django.utils.html import format_html

class ExtPayPalPaymentsForm(PayPalPaymentsForm):
    def render(self):
        form_open  = u'''<form action="%s" id="PayPalForm" method="post">''' % (self.get_endpoint())
        form_close = u'</form>'
        # format html as you need
        submit_elm = u'''<input type="submit" class="btn btn-success my-custom-class">'''
        return format_html(form_open+self.as_p()+submit_elm+form_close)

views.py

from .forms import ExtPayPalPaymentsForm
def paypal(request):
    paypal_dict = {"business":settings.PAYPAL_RECEIVER_EMAIL,"amount": "1.00","item_name": "Milk" ,"invoice": "12345678", "notify_url": "%s%s" % (settings.SITE_NAME, reverse('paypal-ipn')),"return_url": "http://rosebud.mosuma.net",}
    # Create the instance.
    form = ExtPayPalPaymentsForm(initial=paypal_dict)
    context = {"form": form.sandbox()}
    return render_to_response("subscription.html", context)
