RequestsClient headers AttributeError

[Leo T]

The following code produces the following error. Have I missed something? I followed the attached doc.

Code:

client = RequestsClient()
client.headers.update({'x-test': 'true'})

Error:

AttributeError: 'Client' object has no attribute 'headers'

Doc:

http://www.django-rest-framework.org/api-guide/testing/#headers-authentication

Thanks for the help

Hi,

Your code sample works fine on my installation.

Ensure you do use the DRF’s RequestsClient and not Django’s.

Hi Xavier, I am using DRF's RequestsClient, here is the full code:

from django.test import TestCase

from dummy.models import Dummy

from rest_framework.test import RequestsClient

from requests import Session

from user.models import User

class DummyTestCase(TestCase):

client = RequestsClient()

url = '/dummies/'

headers = {'content-type': 'application/json'}

token = ''

headers = {}

def setUp(self):

Dummy.objects.create(name='this is a dummy test')

User.objects.create_user('username', 'email', 'Password1234')

result = self.client.post('/api-token-auth/', data={'username':'username','password':'Password1234'})

self.token = result.data['token']

self.headers['Authorization'] = 'JWT ' + self.token

def test_can_GET_dummies(self):

self.client.headers.update({'Authorization': 'JWT ' + self.token})

#print(self.headers)

response = self.client.get(self.url, headers=self.headers)

self.assertEqual(response.status_code, 200)

self.assertEqual(len(response.data), 1)

As you can see I am setting up a simple Django/DRF/JWT architecture and testing GET on a dummy model. Everything work fine using Postman, curl, etc.. But when I use this code and

python manage.py test

I get the above AttributeError on the headers of my RequestsClient object. If I don't include the faulty line, I get the expected HTTP 401 Unauthorized as I am not sending the JWT token (I removed Basic and Session authentication in the settings).

Any idea of what might cause the problem?

Thanks

Linovia.

No, you are not. See https://github.com/django/django/blob/master/django/test/testcases.py#L221

Thanks Xavier.

For anyone who might run into a similar problem with the same setup: I got it working by overriding the request client in the testcase's setup method.

Is there a reason to use unittest testcase instead of Django testcase? If not, would it make sense to add this caveat in the doc?

Hi,

I was not sure it was in the documentation but it is already:

For drf: http://www.django-rest-framework.org/api-guide/testing/#api-test-cases

For Django: https://docs.djangoproject.com/en/2.0/topics/testing/tools/#customizing-the-test-client

Regards,

Xavier.
