Hi Mike,
When Stripe processes the payment, you need to preventDefault on the form submit, then add the token from Stripe to a hidden input in your form without affecting any other data in the form. Then you can do form.submit() and let the admin handle it from there. Check out the Stripe documentation for some good examples. I've used it myself.

Subject: Re: Admin form_url breakout problem
Matthew
I think I'll back everything out and start again. There must be a basic
blunder somewhere.
Just talking it through, I can definitely launch payment_view from the
Admin when all the ducks are in a line. That view populates the hidden
..._id fields and Stripe API fields in the form then calls the Stripe
API which initiates the Stripe javascript in the Payment template which
resubmits the request with POST direct to Stripe so it can gather the
card detail and send back the json containing the token which proves the
card worked. At that point payment is made and my payment_view has lost
all the context because Stripe made the request not Django. payment_view
detects the Stripe response and must reconstruct the model instances
from the data pre-placed in the hidden form fields. Once the instances
are retrieved that payment_view code updates the subscription record,
creates a receipt record , assembles a message for the success_view and
sends an email to the user.
I am having trouble understanding the correct way to launch payment_view
so that Admin doesn't get confused wanting to add payment/ to the url
and thus keeping it all within the Admin.
Regarding your comment on using reverse to derive the link, I agree. I
was just being somewhat paranoid and skipping the reverse code which I
haven't taken the time to study. I will.
Thanks again
Mike
