Django REST Framework: using TokenAuthentication with browsable API

You can’t use the browsable api with TokenAuthentication. You have to add SessionAuthtication to your settings (http://www.django-rest-framework.org/api-guide/authentication/#sessionauthentication):

REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
    'rest_framework.authentication.TokenAuthentication',
    'rest_framework.authentication.SessionAuthentication',
),
