Re: Django Rest Framework JWT - OperationalError: no such table: auth_user

2019-01-28 Thread El_merendero 
Hi Arthur,
first of all, thanks for your reply, it seems to work. I'm using Django 
1.11.2 and in my settings.py I already had `django.contrib.auth` app in my 
`INSTALLED_APPS`. Anyway I tryed to ran the migrate command and now I don't 
get that Exception any more but an "User doesn't exist." error.

If is not a problem, I ask you another question: my final target is to 
verify a JWT without the username information. I'm documenting about 
"Django REST framework JWT" and I think that it only expects to receive a 
JWT with username (it has the user checker method indeed). Can you tell me 
if there is a configuration or a different tool to perform this target?

Thanks

Hi,

Given you are using python 2.7, I suppose that you are using Django < 1.11.
It seems like you either didn’t add the `django.contrib.auth` app to your
`INSTALLED_APPS` (
https://docs.djangoproject.com/en/1.11/topics/auth/#installation) or
haven’t ran the `./manage.py migrate` command.

Hope this help.

Regards

}


JWT_AUTH = {
'JWT_ISSUER': 'customIssuer'
}


...

and my urls.py in this way:

...


from rest_framework_jwt.views import verify_jwt_token


urlpatterns = [
...
url(r'^api-token-verify/', verify_jwt_token),
...
]

Then, if I try to send a POST request with the above token, I get this
error:
