Das Objekt „str“ hat kein Attribut „get“ ⇐ Python

[Guest]

Ich arbeite an der Braintree-Integration in Django. Ich bin dieser Anleitung gefolgt:

Ich erhalte jedoch die Fehlermeldung „str“-Objekt hat kein Attribut „get“.
Views.py

Code: Select all

from django.shortcuts import render, render_to_response
from django.http.response import HttpResponse
import braintree
braintree.Configuration.configure(braintree.Environment.Sandbox,
"privatekey here",
"merchant key here",
"public key here")

def form(request):
return render_to_response('braintree.html')

def create_transaction(request):
if request.method == 'POST':
print request.POST.get("number")
result = braintree.Transaction.sale({
"amount": "1000.00",
"credit_card": {
"number": request.POST.get("number"),
"cvv": request.POST.get("cvv"),
"expiration_month": request.POST.get("month"),
"expiration_year": request.POST.get("year")
},
"options": {
"submit_for_settlement": True
}
})

if result.is_success:
return "Success! Transaction ID: {0}".format(result.transaction.id)
else:
return "Error: {0}".format(result.message)
else:
return HttpResponse('no post')

Die Ausnahme ist

Code: Select all
