Making Stripe User Checkout Email as {{ request.user.email }} in Django project - django

Question

Hi Djangonauts,
I am integrating stripe in my in my project. I do not want users to enter their email in their stripe payment form. Instead I want the email they registered on my site as their checkout email. I have the below form. When this form renders. It asks for users.
Name:,
Email:,
Billing Address:,
Credit Card Details:,
Can I change email from
email = request.POST['stripeEmail']
to
If user.is_authenticated:
email = request.user.email
I am aware that by doing this anonymous users will not be able to checkout and I am ok with that. I can add #loginrequired() decorator before the function
I have Order history view
#login_required()
def orderHistory(request):
if request.user.is_authenticated:
email = str(request.user.email)
order_details = Order.objects.filter(emailAddress=email)
return render(request, 'order/order_list.html', {'order_details': order_details})
This code fetches Orders in Order History order_details = Order.objects.filter(emailAddress=email) when users sign up with 1 email and use another email at checkout the orders don't appear in their Order history. Plus it is mandatory to have a account to checkout that's why I needed the below
Below are the views.py of my shopping cart
def cart_detail(request, total=0, counter=0, cart_items=None):
try:
cart = Cart.objects.get(cart_id=_cart_id(request))
cart_items = CartItem.objects.filter(cart=cart, active=True)
for cart_item in cart_items:
total += (cart_item.tasting.price * cart_item.quantity)
counter += cart_item.quantity
except ObjectDoesNotExist:
pass
stripe.api_key = settings.STRIPE_SECRET_KEY
stripe_total = int(total * 100)
description = 'Khal: Share your recipes - New tasting request'
data_key = settings.STRIPE_PUBLISHABLE_KEY
if request.method == 'POST':
# print(request.POST)
try:
token = request.POST['stripeToken']
email = request.POST['stripeEmail']
billingName = request.POST['stripeBillingName']
billingAddress1 = request.POST['stripeBillingAddressLine1']
billingCity = request.POST['stripeBillingAddressCity']
billingZipcode = request.POST['stripeBillingAddressZip']
billingCountry = request.POST['stripeBillingAddressCountryCode']
customer = stripe.Customer.create(
email=email,
source=token
)
charge = stripe.Charge.create(
amount=stripe_total,
currency='usd',
description=description,
customer=customer.id,
)
'''Creating the Order'''
try:
order_details = Order.objects.create(
token=token,
total=total,
emailAddress=email,
billingName=billingName,
billingAddress1=billingAddress1,
billingCity=billingCity,
billingZipcode=billingZipcode,
billingCountry=billingCountry,
)
order_details.save()
for order_item in cart_items:
oi = OrderItem.objects.create(
tasting=order_item.tasting.post.title,
quantity=order_item.quantity,
price=order_item.tasting.price,
order=order_details
)
oi.save()
'''Reduce stock when Order is placed or saved'''
tastings = Tasting.objects.get(id=order_item.tasting.id)
tastings.stock = int(order_item.tasting.stock - order_item.quantity)
tastings.save()
order_item.delete()
'''The terminal will print this message when the order is saved'''
print('The order has been created')
try:
'''*********************Calling the sendEmail function************************************'''
sendEmail(order_details.id)
print('The order email has been sent to the customer.')
except IOError as e:
return e
return redirect('order:thanks', order_details.id)
except ObjectDoesNotExist:
pass
except stripe.error.CardError as e:
return False,e
return render(request, 'cart/cart.html', dict(cart_items=cart_items, total=total, counter=counter, data_key=data_key,
stripe_total=stripe_total, description=description))
I have also attached below my cart.html template
<form action="" method="POST">
{% csrf_token %}
<script
src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="{{ data_key }}"
data-amount="{{ stripe_total }}"
data-name="Perfect Cushion Store"
data-description="{{ description }}"
data-image="{% static 'images/logo.png' %}"
data-locale="auto"
data-currency="usd"
data-shipping-address="true"
data-billing-address="true"
data-zip-code="true">
</script>
</form>

I believe you can hide email by including data-email into the stripe script :
cart.html:
<form action="" method="POST">
{% csrf_token %}
<script ... data-email="{{request.user.email}}"></script>
</form>
You could then retrieve stripeEmail or directly use request.user.email in your view.
