Get user object from token string in DRF?

from rest_framework.authtoken.models import Tokenuser = Token.objects.get(key='token string').user

Here is The default authorization token model:

@python_2_unicode_compatibleclass Token(models.Model):    """    The default authorization token model.    """    key = models.CharField(_("Key"), max_length=40, primary_key=True)    user = models.OneToOneField(        settings.AUTH_USER_MODEL, related_name='auth_token',        on_delete=models.CASCADE, verbose_name=_("User")    )    created = models.DateTimeField(_("Created"), auto_now_add=True)    class Meta:        # Work around for a bug in Django:        # https://code.djangoproject.com/ticket/19422        #        # Also see corresponding ticket:        # https://github.com/encode/django-rest-framework/issues/705        abstract = 'rest_framework.authtoken' not in settings.INSTALLED_APPS        verbose_name = _("Token")        verbose_name_plural = _("Tokens")    def save(self, *args, **kwargs):        if not self.key:            self.key = self.generate_key()        return super(Token, self).save(*args, **kwargs)    def generate_key(self):        return binascii.hexlify(os.urandom(20)).decode()    def __str__(self):        return self.key

As you can see this model has OneOnOne relations with the User model.

So if you want to get the User than mapped to specific Token:

from rest_framework.authtoken.models import Tokentry:    Token.objects.get(key="token").userexcept Token.DoesNotExist:    pass

For more information see Authentication documents

If you invoke the user object directly from the Token class, as presented in @aliva's solution, you will get a raw partial Django User with just the fields living in the database. If you need to get the real user object, with e.g. its computed properties, you can do this:

from rest_framework.authtoken.models import Tokenuser_id = Token.objects.get(key=request.auth.key).user_iduser = User.objects.get(id=user_id)
