I'm working on Braintree intergration in Django. I've followed this guide:

However, I'm getting the error 'str' object has no attribute 'get'.

Views.py

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 "<h1>Success! Transaction ID: {0}</h1>".format(result.transaction.id)
        else:            
            return "<h1>Error: {0}</h1>".format(result.message)
    else:      
        return HttpResponse('no post')

The exception is

    What is the *full* traceback of the exception? In the Django error view, do click on the link to get the textual view of the traceback. – Martijn Pieters Mar 21 '14 at 12:58

  • I work at Braintree. If the below answer doesn't solve your problem, you can always [reach out to our support team](https://support.braintreepayments.com/) for more help. – agf Mar 21 '14 at 16:09
  • @agf: if possible then can you send me better documentation than in the official website – user2224250 Mar 21 '14 at 17:11
  • @user2224250 In this case, the problem looks to be caused by a difference between Django and Flask (we use Flask in our guides) -- in Flask, you can return strings from your views; in Django, you need to return `HTTPResponse` objects. If you have more problems, our support team (reachable at the URL in my other comment) should be able to help. – agf Mar 21 '14 at 17:42

You're returning strings directly from create_transaction inside the POST block. You need to wrap them in an HttpResponse.

open clickjacking.py of django middleware and change the following code

first import in what way you have to give response 
like in my case I have to return httpredirect so i import 
from django.http import HttpResponseRedirect
if isinstance(response, str):
        response = HttpResponseRedirect(response)
add this code into process_response of clickjacking.py
