An almost working view for django-braintree

django_braintree_almost_working.py

# Note: this is just for testing, and doesn't do stuff like set the amount or redirect if successful.
#
# This tidbit was created primarily to troubleshoot why I couldn't submit a form with validation errors
# twice without being redirected to https://sandbox.braintreegateway.com/login
#
# Tested using Python 2.6.6, django 1.2.5, django-braintree 1.5, and braintree 1.8
def make_payment(request):
    result = TransactionForm.get_result(request)
    form = TransactionForm(result, redirect_url='http://127.0.0.1:8000/make_payment/')
    form.generate_tr_data()
    
    # When I'm redirected back to make_payment with validation errors,
    # inspection of form.fields['tr_data'].initial reveals the expected data.
    #
    # However, if you fire up Chrome, CMD-alt-i, and examine the source,
    # you'll see the hidden input has been rendered, but without any data.
    #
    # What gives?

    return direct_to_template(request, 'make_payment.html', { 'form': form })
