FormViewはform_valid（）メソッドを実行しません

Question

Braintreeを支払いソリューション（サンドボックス）として使用しています。フォームを塗りつぶすと、同じページにリダイレクトされます。私のエラーは、フォームがプロセスを取得しないということです。 FormViewコントロールにのみget_context_data()が実行されたではなく、form_valid()

HTML

<script src="https://js.braintreegateway.com/web/dropin/1.6.1/js/dropin.min.js"></script> 

<form action="{% url 'checkout_braintree' %}" method="POST" id="payment-form"> 
    {% csrf_token %} 
    <h3>Method of Payment</h3> 
    <p>378282246310005</p> 
    <input type="hidden" id="nonce" name="payment_method_nonce" /> 

    <div class="bt-drop-in-wrapper"> 
     <div id="bt-dropin"></div> 
    </div> 
    <button class="button" type="submit" id="submit-button"><span>Test Transaction</span></button>

するvarフォーム= document.querySelector（ '＃支払いフォーム'）;

braintree.dropin.create({ 
    authorization: '{{ client_token }}', 
    container: '#bt-dropin',

あなたはform_validとform_invalidメソッドを持っており、また、あなたがこれまであなたsuccess_url同様のを編集している場合、フォーム

from django import forms 
class BraintreeSaleForm(forms.Form): 
    payment_method_nonce = forms.CharField() 

Answer 1

はあなたのviews.pyが良くなります。

    template_name = 'startupconfort/cart.html' 
    success_url = '/'

    def get_context_data(self, **kwargs): 
     # import ipdb; ipdb.set_trace() 
     context = super().get_context_data(**kwargs) 
     context['client_token'] = get_braintree_client_token() 
     return context 

    def form_valid(self, form): 
     # import ipdb; ipdb.set_trace() 
     user = self.request.user 
     nonce = form.cleaned_data['payment_method_nonce'] 

     result = braintree.Transaction.sale({ 
      "amount": get_total_price_of_the_shipping_cart(user),
