I need to access a djangorestframework api but because the django server uses CSRF token and i cant get past it. How can i configure djangorestframework to override the djangorestframework and not be redirected to login?
Im new to this so i need help.
accessing the django rest framework would be a pure python program which runs in the background of a client pc collecting data so i need to use urllib2 or request for this. any ideas?
The API needs to expose an authentication method for your client to use.
The SessionAuthentication style requires CSRF validation and is suuitable for javascript based clients, running in the context of a logged-in application. If this describes the sort of client access you're making then read the Django documentation on CSRF and AJAX requests, which describes how to pass a CSRF token to a javascript based client.
Other schemes such as TokenAuthentication do not require CSRF validation, and will successfully authentication without passing any CSRF token.
Make sure that you know what schemes the API supports and choose the right one to use for your client access.
For more information see the authentication documentation.

In my django web app, which is split into a front and and a back end project, I am currently using a custom AuthBackend class that extends django's BaseBackend, as well as DRF's UserTokenAuthentication.
Am I right to think that I only need one of these approaches? Or is there a reason to use django's login() function, even if i am using DRF's token auth? I know it stores the user in the session, so I guess that would make passing and authenticating a token pointless?
What's my best approach? Cheers :)
There are differences in both namespaces wise and purpose wise.
In Django, auth backends handle session-based authentication only whereas rest framework auth supports not only session-based auth but also token (JWT, OAuth ), and basic auth based authentication.
Besides, Django auth backends authenticate requests during passing through middle-ware and rest framework authenticate without middle-ware.
If you are planning to separate your backend and frontend then go for token-based auth. There is no reason to use the login function of Django if you only use token-based auth to authenticate.
I have a React frontend running at frontend.example.com and a Django backend with DRF running at backend.example.com. I am using Django Session Authentication and I want to properly implement CSRF protection.
Taking the React login page frontend.example.com/login as an example. It's the first time for a user to visit the page. There is a form with a user and password and on submit a new POST request is created to the Django backend. To the best of my knowledge, the CSRF token cookie should already be included in this request, right?
How to obtain that CSRF token from the Django backend? I am thinking of doing a GET request to the Django backend on loading the login-page to obtain that CSRF token cookie. Is that the way to do it or is there any other best practice?
Django has a section for AJAX request and how to handle CSRF: AJAX
Using this method you should send the token over and over again for each post request. The other method is using CORS. in this method, you only respond to the domains that you already whitelisted with headers that are whitelisted as well. So, instead of getting and passing CSRF token, you check if the request is coming from the right domain and then you can respond to it. And combining with a token system for user authentication, you should be good.
You can use this package for handling CORS if you use DRF: django-cors-headers
Using rate limiting can also help you avoid spams and robots to do noticeable harm.
I am building an application after finishing up my website. Now, the backend for both of these should be common, but Django's csrf token is meant to be a security against this. Since I am not using a web browser, I am unable to get a csrf token cookie. At the same time, django will need it to access its APIs.
Is there any way I can get the cookie from Django and get it into React Native?
Not clear what you want to do. But if you are writing a native application, why don't you use a token identification mechanism?
There are lots of simple (and less simple solutions out there).
Assuming you are using django rest framework.
Simple built-in Token authentication

Token, but with expiry and DB encryption

JWT

May I know your login URL? Use rest-auth login URL. Allauth URL gives Csrf issue.
I am using Django + Django REST Framework + Django OAuth Toolkit.
I understand that AJAX calls from a web session require CSRF protection, but it is my understanding that mobile apps don’t as the very thing CSRF check are protecting against can’t happen in a dedicated app. If a person has an OAuth token, they are not using our web app so it seems I don’t need to perform CSRF checks in that case.
Is there any way to disable CSRF checks on REST Framework endpoints when a request includes an OAuth token, and if so is this a safe thing to do? Or should all requests be protected by the CSRF mechanism regardless?
You should probably be using DRF's token authentication with a mobile app. Initially, the user logs in to your backend with a username and password and then the backend issues a token for that instance of the mobile app, which [securely] stores the token locally. With token authentication and the reality of sending your credentials (over SSL/HTTPS) to the server on every request, you obviate the need for a CSRF check and thus no CSRF check is done.
i'm currently learning about django-rest and i'd like to interact with an Angularjs application.
The main idea is to build an API with django-rest serving on localhost:8000 and call it with a nodejs/angularjs serving on localhost:9000
the main question is: how to authenticate an user through angularjs ?
The documentation says
Session authentication is appropriate for AJAX clients that are
running in the same session context as your website.
because django and angularjs are not in the same context, does it means i have to use oauth2 to play with authentication ?
Thanks for your lights :)
does it means i have to use oauth2 to play with authentication?
Of course not. You can use TokenAuthentication or even BasicAuthentication.
I myself most of the times use something similar to TokenAuthentication but handmade. The only concern here is passing token in requests.
EDIT:
If you perchance not satisfied with options provided by Django REST you can write your own middleware to handle authentication. The idea here is to authenticate user. Pass to him some token and then check for that token in your custom middleware.
