Question

Django

TypeError: 'NoneType' object is not subscriptable

if request['user_type']=='driver' and not Driver.objects.filter(user_id = user.id):
TypeError: 'NoneType' object is not subscriptable

from TarFoodApp.models import Customer,Driver

def create_user_by_type(backend , user , request , response , *args, **kwargs):
    if backend.name == 'facebook':
        avatar = 'http://graph.facebook.com/%s/picture?type=large' % response['id']
    if request['user_type'] =='driver' and not Driver.objects.filter(user_id = user.id):
        Driver.objects.create(user_id=user.id,avatar=avatar)
    elif not Customer.objects.filter(user_id=user.id):
        Customer.objects.create(user_id=user.id, avatar=avatar)

the error is most likely in request['user_type']=='driver' since I remove this code, then the request works ;

I send it with POSTMAN ; if you need to throw off more screenshots I ask the first time a question of this type))

Answer 1

decision

def create_user_by_type(backend , user , response , *args, **kwargs):
    request = backend.strategy.request_data()

    if backend.name == 'facebook':
        avatar = 'http://graph.facebook.com/%s/picture?type=large' % response['id']
    if request['user_type'] == 'driver' and not Driver.objects.filter(user_id = user.id):
        Driver.objects.create(user_id=user.id,avatar=avatar)
    elif not Customer.objects.filter(user_id=user.id):
        Customer.objects.create(user_id=user.id, avatar=avatar)

Answer 2

Use the debugger and you will see that either request or user is None.

Answer 3

request['user'] there is no such thing, there is request.user the full code of the view would not hurt or where is this error
