ApiKey Authentication issue 'SimpleLazyObject' with GET while accessing request.user

[Ashish Tiwari]

Hi all,

I'm new to tastypie, I'm facing issue with the ApiKeyAuthentication with GET method.

I created an Account model that have foreign-key of User.

class Account(models.Model):

    user = models.ForeignKey(User)

    uuid = models.CharField(max_length = 36)

    score = models.CharField(max_length = 36)

class Practice(models.Model):

    account = models.ForeignKey(Account)

    practice_type=models.CharField(max_length = 36)

    app_id=models.CharField(max_length = 36)

I want to update the Account's score when user passing "app_id" and "practice_type" , Below is PracticeResource.

I'm using prepend_url method to pass the "app_id" and "practice_type".

class PracticeResource(ModelResource):

    class Meta:

        queryset = Practice.objects.all()

        resource_name = 'practice'

        authorization = Authorization()

        authentication = MultiAuthentication(ApiKeyAuthentication(), SessionAuthentication())

        always_return_data=True

    def prepend_urls(self):

        return [

        url(r"^(?P<resource_name>%s)/levels%s$"%(self._meta.resource_name,trailing_slash()),self.wrap_view('get_practice_levels'), name="api_get_levels"),

        ]

    def get_practice_levels(self,request,**kwargs):

    # some rules goes here, if practice_type= 1 then score 100, if 2 then 200 .....etc

    account = Account.objects.get(user=request.user)

    account.score="100"

    account.save()

I'm passing Authorization information in header,

curl -i -H "Authorization: ApiKey AbdH:65ca30f75933b8aec" -H "Content-Type: application/json" http://localhost:8000/api/v1/practice/levels/?app=e2c2c1e6-d886-4efe-bd0e-43db839deac8&type=1

Tastypie throws an error at 

500 : Internal Server Error

>>> account = Account.objects.get(user=request.user)

TypeError: "int() argument must be a string or a number, not 'SimpleLazyObject'

Thanks.

Figured out the issue and solved it by doing following code changes.

account = Account.objects.get(user__username=username)

For api_key authentication in function, I used.

        self.method_check(request, allowed=['post','get'])

        self.is_authenticated(request)

        self.throttle_check(request)
