[django-oscar] Re: Add a new payment gateway to Oscar

[Veronica Jones]

I am currently trying to integrate Stripe into Django-Oscar but feel that 
this code might be a little outdated now. Would any of y'all suggest an 
updated version of this code?

I am trying to figure it out myself, but am confused on how to split up the 
Stripe Payment 'form' from the submit button, while keeping whatever data 
was entered into the Stripe Payment 'form'. I put quotes around form 
because I am not referring to a Django form, but the Stripe embedded form.

I appreciate any help.

Does anyone know if and how it is possible to add another payment way, like 
Ideal? This should be possible with Stripe. Does anyone have any experiecen 
with this and can help me out? 
P.s. the above method works good for me, thanks!

[django-oscar] Re: Add a new payment gateway to Oscar

[Dyoser]

Hi Joseph , thanks for the step by step instructionreally helpful

But i've a question about where to put what in what folder.
I've a shop called tpwshop do i need to create an apps folder inside my 
shop folder and also a checkout one?

Is that the way to extend Oscar's payment?

If you could clarify this it would be an enormous help.


Here is a pic of my actual folder structure

Thanks!

[SammyJ]

Hi, this error occurs when your payment form is invalid.Have you set up 
stripe in the checkout app?

Maybe you could check out this Solution 

 on 
stackoverflow, look at the first answer. I guess it might help you solve 
your issue.

[django-oscar] Re: Add a new payment gateway to Oscar

[Calvin Kcc]

I have forked the checkout app and created all these files. But for some 
reason it keep saying there is no module named "facade" when I have 
facade.py in my checkout directory.

[django-oscar] Re: Add a new payment gateway to Oscar

[Andrew Edwards]

Awesome post Joseph!

I just wanted to update this for as of this post's creation time. I had to 
modify the end of the Facade class with:

except stripe.error.CardError as e:
raise UnableToTakePayment(self.get_friendly_decline_message(e))
except stripe.error.StripeError as e:
raise InvalidGatewayRequestError(self.get_friendly_error_message(e))


instead of:

except stripe.CardError, e:
raise UnableToTakePayment(self.get_friendly_decline_message(e))
except stripe.StripeError, e:
raise InvalidGatewayRequestError(self.get_friendly_error_message(e))


***If you don't follow this next step, the transaction will never 
complete.***
I also had to add to my preview template in the block 'hiddenforms':


{% block hiddenforms %}
{{ stripe_token_form }}
{% endblock %}


This allowed the stripe payment details to persist to the preview page and 
so when the user clicks the place order button the payment is actually 
taken from the card.

One other thing I had to do was modify the else statement of the 
get_context_data method in your local PaymentDetailsView class such that 
the total price appears in the 'Pay' button of the Stripe form when you are 
entering payment details on the payment details page:

def get_context_data(self, **kwargs):
ctx = super(PaymentDetailsView, self).get_context_data(**kwargs)
if self.preview:
ctx['stripe_token_form'] = forms.StripeTokenForm(self.request.POST)
ctx['order_total_incl_tax_cents'] = (
ctx['order_total'].incl_tax * 100
).to_integral_value()
else:
ctx['order_total_incl_tax_cents'] = (
ctx['order_total'].incl_tax * 100
).to_integral_value()
ctx['stripe_publishable_key'] = settings.STRIPE_PUBLISHABLE_KEY
return ctx


Hope this helps someone!
