Python Django Rest Framework authentication -

i attempting authenticate guid being passed in url via web api interface. not managing pass guid authenticate class.

note: authenticating mean making sure valid guid

my urls.py:

 url(r'^customer_address/(?p<guid>[a-z0-9-]+)/(?p<address_id>[a-z0-9-]+)/$',     views.customeraddressview.as_view()), 

my views.py:

class customeraddressview(generics.retrieveapiview):     lookup_field = "address_id"            queryset = customeraddress.objects.all()     serializer_class = customeraddressserializer      

my settings.py:

rest_framework = {         'default_authentication_classes': (             'customer.authenticate.authenticate',         ),          'default_permission_classes': (         'rest_framework.permissions.isauthenticated',          ) } 

authenticate class in customer app looks this:

class authenticate(authentication.baseauthentication) :     def authenticate(self, request):          request = request._request                                        guid = getattr(request, 'guid', none)           my_logger.debug(guid)           if not guid:             my_logger.debug('there no guid!')             return none           try:             user = customer.objects.get(guid=guid,brand=1)         except customer.doesnotexist:             raise exceptions.authenticationfailed('no such user')          return none 

and request looks this:

problem: retrieve guid in class authenticate , make sure valid. @ moment keep getting error see in screenshot , logs read: 'there no guid!'

how can pass guid request authenticate class?

thanks

you can this:

class authenticate(authentication.baseauthentication) :     def authenticate(self, request):          request = request._request                  # bit hacky way value of guid                                 guid = request.path.split('/')[-3]          my_logger.debug(guid)          if not guid:             my_logger.debug('there no guid!')         return none          try:             user = customer.objects.get(guid=guid,brand=1)         except customer.doesnotexist:             raise exceptions.authenticationfailed('no such user')      return none 

this bit hacky since trying access guid splitting request.path '/' , access third-last index of list obtained after splitting.

i have checked, self has no access kwargs in drf views, can't access kwargs here.

another solution pass kwargs in drf view explicitly when authenticate() called overriding authentication process of drf.
