Django admin suddenly logging out only on production enviorment

When i check the browser storage, there are 3 cookies: csrftoken, sessionid and djdt. all of them with a large expiration time ( at least one week ).

SESSION_COOKIE_DOMAIN = env.str('SESSION_COOKIE_DOMAIN', default=None) # Whether the session cookie should be secure (https:// only). SESSION_COOKIE_SECURE = not DEBUG # why it doesn't resolve the sundenly logout problem!? SESSION_COOKIE_AGE= 24*60*60*7 I tried the following issues, but they doesn't work for me: Django development server keeps logging out Django admin logging out on model save any help will be apreciated -

My django rest api returns ID and password on authentication in response to react client
Login Function function login(username, password) { return dispatch => { dispatch(request({ username })); userService.login(username, password) .then( user => { dispatch(success(user)); history.push('/home'); window.location.reload() }, error => { dispatch(failure(error.toString())); dispatch(alertActions.error(error.toString())); } ); }; function request(user) { return { type: userConstants.LOGIN_REQUEST, user } } function success(user) { return { type: userConstants.LOGIN_SUCCESS, user } } function failure(error) { return { type: userConstants.LOGIN_FAILURE, error } } } async function login(email, password) { const axios = require('axios') const url = process.env.REACT_APP_AXIOS_URL; return axios({ method: 'post', url: `${url}/api-token-auth/`, data: { "email": email, "password": password, } }) .then(handleResponse) .then(user => { localStorage.setItem('user', JSON.stringify(user.data.token)); return user; }); } function handleResponse(response) { if (response.status !== 200){ if(response.status === 401){ logout() window.location.reload() } // const error = (data && data.message) ||response.statusText; return Promise.reject(response) } return response;} I dont think that problem will be on django side. I don't understand why the response return all data including ID and password when it is a post request. Is it standard and will it lead to big security loop holes? thank you for your help -
Django fails to login user
Authenticating a user using valid credentials passes on the login view. When request.user.is_authenticated is printed, it even outputs True. But after redirecting to LOGIN_REDIRECT_URL, the request is returned back to LOGIN_URL meaning the just authenticated user is no longer authenticated. The project in concern is a mixed project i.e It uses core django builtin view, route and templating as well as djangorestframework. djangorestframework TokenAuthentication has worked fine so far, but when i try logging in with core django view i get this weird situation. I'm using a custom auth user model and two backend authentication ( which are all working fine on api authentication and authorization ). Every other aspect of the project works fine, the only issue is this authentication. I've tried several resource to fix this, but all lead to dead ends. I even used functional based view and django builtin LoginView (as an inherited class and on path route ), same occurence i got irrespective.

NoReverseMatch error with default django authentciation app
I am getting a http 500 NoReverseMatch error while trying to do a password reset. The error is: Exception Value: Reverse for 'password_reset_confirm' with keyword arguments '{'uibd64': 'MQ', 'token': 'aacknw-b2a16b47efcb9e103d0375c1793945f1'}' not found. 1 pattern(s) tried: ['accounts/reset/(?P<uidb64>[^/]+)/(?P<token>[^/]+)/$'] However the 4 password reset URLS are already created by default, and the password_reset_confirm URL which accepts uidb64 and tokens already exists by default: accounts/password_reset/ [name='password_reset'] accounts/password_reset/done/ [name='password_reset_done'] accounts/reset/<uidb64>/<token>/ [name='password_reset_confirm'] accounts/reset/done/ [name='password_reset_complete'] If I try to access it manually by going to accounts/reset/<randomuid>/<randomtoken> it works! The template for the page loads. [EDIT] So the error appears to be internal when password_reset possibly tries to communicate with password_reset_confirm to try and pass tokens maybe? I feel like there is a wierd internal server error which maybe I caused with miss setting something but I have combed through the project multiple times. -

Creating django select-2 custom widget
I am trying to add a django custom select2 in my site. However, it looks like my js file is not being read properly. I have been stuck troubleshooting this error, does anyone have insight on what might be happening?

Why does Django Rest Framework add a slash on my URL when i filter?
I'm just getting started to Django Rest Framework and i created my first endpoints. Now, i'm trying to add filtering to my URLS but there are two things i don't understand yet: I created the following route: router.register(r'endpoint', views.myView, basename='myView'). When i try to filter on my browser like the following http://127.0.0.1:8000/api/endpoint?&user=TEST, i will get redirected to http://127.0.0.1:8000/api/endpoint/?&user=TEST. Why is there a slash before the ?? What is the difference between using router.register and a standard view on my urlpatterns like i would do in Django?
