I am trying to integrate the Stripe payment gateway to Django oscar for an e-commerce site which sells physical goods like groceries online.I use python 3.6.3, Django 2.0, Django-oscar 1.6, stripe 1.82.2.
Method 1:
So I followed this link in django-oscar groups:
I have signed up for a stripe account and used my publishable key and test key to configure stripe.The problem is, when I try to pay using the button provided with label "Pay with Card",it collects my card information and then when I click the button, it shows "Some money will be debited from the card" like in this image: Image of Preview page
Then after I click the place order button,it shows me this: Image of confirmation page
Though I have paid using my card. I guess oscar doesn't seem to know that the payment has been done through stripe already?But I'm not sure how to solve this.
Method 2: I tried to use dj-stripe,found here:
https://github.com/dj-stripe/dj-stripe
But I read the whole documentation on https://dj-stripe.readthedocs.io/en/stable-1.0/ , it seems like I can use it only for products that need subscriptions, mine don't require subscribing and the docs for dj-stripe aren't fully complete.
I tried with the official django-oscar repo, the link is here: https://github.com/django-oscar/django-oscar-stripe , this repository is like five years old and I don't think it would be compatible to use with my version of Django oscar.
Method 3: I tried using the stripe.js and elements and created my form to accept cards:
< script src = "https://js.stripe.com/v3/" > < /script> <
script >
var stripe = Stripe('your_stripe_publishable_key');
var elements = stripe.elements();
// Custom styling can be passed to options when creating an Element.
var style = {
base: {
color: '#32325d',
lineHeight: '18px',
fontFamily: '"Helvetica Neue", Helvetica, sans-serif',
fontSmoothing: 'antialiased',
fontSize: '20px',
'::placeholder': {
color: '#aab7c4'
}
},
invalid: {
color: '#fa755a',
iconColor: '#fa755a'
}
};
// Create an instance of the card Element.
var card = elements.create('card', {
style: style
});
// Add an instance of the card Element into the `card-element` <div>.
card.mount('#card-element');
card.addEventListener('change', function(event) {
var displayError = document.getElementById('card-errors');
if (event.error) {
displayError.textContent = event.error.message;
} else {
displayError.textContent = '';
}
});
// Create a source or display an error when the form is submitted.
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
stripe.createSource(card).then(function(result) {
if (result.error) {
// Inform the user if there was an error
var errorElement = document.getElementById('card-errors');
errorElement.textContent = result.error.message;
} else {
// Send the source to your server
stripeSourceHandler(result.source);
}
});
});
function stripeSourceHandler(source) {
// Insert the source ID into the form so it gets submitted to the server
var form = document.getElementById('payment-form');
var hiddenInput = document.createElement('input');
var hiddenAmount = document.createElement('input');
hiddenInput.setAttribute('type', 'hidden');
hiddenInput.setAttribute('name', 'stripeSource');
hiddenInput.setAttribute('value', source.id);
form.appendChild(hiddenInput);
hiddenAmount.setAttribute('type', 'hidden');
hiddenAmount.setAttribute('name', 'amt');
hiddenAmount.setAttribute('value', '{{ order_total.incl_tax|safe }}');
form.appendChild(hiddenAmount);
// Submit the form
form.submit();
}
<
/script><form action="/charge/" method="post" id="payment-form">
{% csrf_token % }
<div class="form-row">
<label for="card-element">
Credit or debit card
</label>
<div id="card-element">
<!-- A Stripe Element will be inserted here. -->
</div>
<!-- Used to display Element errors. -->
<div id="card-errors" role="alert"></div>
</div>
<br>
<!--<hr>-->
<button class="btn btn-primary">Pay Now</button>
</form>And in my python views.py file I create a stripe charge and also sources.
@csrf_exempt
def stripe_payment(request):
user = request.user
source_id = request.POST.get("stripeSource", None)
amount = request.POST.get("amt", None)
stripe.api_key = "your_test_key"
customer = stripe.Customer.create(
email=email,
source=source_id,
)
# print("Customer ID: ", customer['id'])
amt = float(amount) * 100
# print("Amount:", int(amt))
int_amt = int(amt)
charge = stripe.Charge.create(
amount=int_amt,
currency='cad',
customer=customer['id'],
source=source_id,
)
return HttpResponseRedirect("/checkout/preview/")
Then I created a webhook in the stripe dashboard and linked it to my local url , every-time there is a response from stripe being sent through the web-hook, this url is hit.
@csrf_exempt
def demo_checkout(request):
# Retrieve the request's body and parse it as JSON:
event_json = json.dumps(json.loads(request.body), indent=4)
# event_json = json.loads(request.body)
# Do something with event_json
print("Json event:", event_json)
return HttpResponse(status=200)
As of now, I can track the various events or logs from my dashboard and the events like creating a customer, making a charge and the web-hook sending a response is working fine,but I can't figure out how can I complete the payment such that Django-oscar can also know that the payment is done and it doesn't show "No payment was required": Thank you page
I have tried all these methods,but it still doesn't work.I am open to using any other method which is suggested or an improvement to what I have done in any of the methods explained so far.I am new to django-oscar and an answer with some code and some explanation would be helpful.
I have found a way to integrate Stripe with Django Oscar, this is one of the easy ways to do it.
Create a stripe account first from here:https://stripe.com/, you will get a publishable key and a secret key, you can view them after logging in into the stripe dashboard under Developers > API keys.
In your django oscar code side. Fork the checkout app from oscar, add it to the INSTALLED_APPS+=get_core_apps(['checkout']).To know how to fork an app you can follow this link from the docs:https://django-oscar.readthedocs.io/en/latest/topics/customisation.html#fork-oscar-app
Create a file called facade.py under checkout, copy the keys from your dashboard into the settings.py file and do the other changes as suggested in this link: Stripe payment gateway integration on the django oscar groups, it just happens to be titled wrong.Just follow this whole page and it's done.
