Setting the expiry of access token using drf-social-oauth2
So I am using DRF, React and drf-social-oauth2 for Google Login and I want to set the expiry time of the access token given after Google login. I tried using the same settings as OAuth Toolkit OAUTH2_PROVIDER = { 'ACCESS_TOKEN_EXPIRE_SECONDS': 10, 'OAUTH_SINGLE_ACCESS_TOKEN': True, 'OAUTH_DELETE_EXPIRED': True } which means expiry should be 10 seconds, but the response is, access_token: "d2UAuxY5uv9sEtlE60pgMeuLqTuJV1" expires_in: 33352.043033 refresh_token: "fhm8Zy88HaitJF6q3QEwmSEd3bC1wU" scope: "read write" token_type: "Bearer" the expires_in is wierd. What does this mean? And how do I set the expiry for drf-social-oauth2, can't find any help regarding this anywhere -

CSRF Verification with Arduino

Django crispy forms renders select2 field twice
I am using django crispy forms for a ModelForm. In this form I have a field which I would like to display as a Select2MultipleWidget (Provided by django-select2). When displaying the form like this: {{ form }} the field renders just fine.

Why is this happening? Should I simply use the filter instead of the tag or is there any workaround here? -

Django stand alone app - sharing data with projects that use standalone app
I am using Django 3.2. I have written a stand alone app that handles user profile management. The app use MaxMindDb to map IP addresses to Countries and Cities. Applications that use my app, need to set a variable GEOIP_PATH in their settings.py file. Currently, I'm having to do this: GEOIP_PATH = os.path.join(BASE_DIR, 'geodata') Which means that I will have to make copies of the huge database for each project using the app. Is there a way to package the MaxMindDb with my app, so that I can refer to it's location a bit like this: GEOIP_PATH = os.path.join([PATH_TO_PIP_INSTALLATION_OF_MY_STANDALONE_APP], 'geodata') -

Django doesn't validate or see the JWT token from Azure
I used azure-ad-verify-token 0.2.1 on Django-rest backend to validate a jwt token from Microsoft Azure, where the user is authenticated on the frontend with React. According to the documentation, this library should do everything on its own. from azure_ad_verify_token import verify_jwt azure_ad_app_id = 'my app id' azure_ad_issuer = 'https://exampletenant.b2clogin.com/0867afa-24e7-40e9-9d27-74bb598zzzzc/v2.0/' azure_ad_jwks_uri = 'https://exampletenant.b2clogin.com/exampletenant.onmicrosoft.com/B2C_1_app_sign_in/discovery/v2.0/keys' payload = verify_jwt( token='<AZURE_JWT_TO_VERIFY_HERE>', valid_audiences=[azure_ad_app_id], issuer=azure_ad_issuer, jwks_uri=azure_ad_jwks_uri, verify=True, ) print(payload) I don't understand the line token='<AZURE_JWT_TO_VERIFY_HERE>', how can I put the token there? Authorization from Azure on React is successful, and I get a access jwt-token that I can extract: token = request.headers['Authorization'] But I need to validate it and somehow insert it into a string token='<AZURE_JWT_TO_VERIFY_HERE>', but it doesn't recognize the request here. How can I put a token= from the header? And in general, is this the right way? Or am I missing something? Any help and hints would be very helpful and would be greatly appreciated. Or advise another library for token validation in Python. -
Generate a link to Stripe Customer Account Link regardless of the current browser account
I'm using Stripe in Django, I would like to generate a navigation link from django admin portal to Stripe Customer Account. eg: [Customer Id] I've concatenated the id to the following url: "https://dashboard.stripe.com/customers/" to be "https://dashboard.stripe.com/customers/cus_LX88WdbprptpWe" If I click the link, supposedly it opens the Stripe Account and navigates to the customer, this is incase the customer exists in this account. While if the customer actually exists, but currently in the browser I'm logged on a different stripe account, the customer response will not be found. eg: [Customer not found] What I wonder is how to generate a valid stripe customer account link that redirects to the customer's account as well as the correct Stripe Account to avoid the "not found customer" issue.
