django rest social auth custom PIPELINES does not work at all
I create social auth with facebook and google and they work just fine. However, when I user register by the classic django signup I would send them an email to verify their account then i set user.is_email_verified to True. So, it does not make sense to ask user to verify their email if they register via social auth, and I need to set is_email_verified==True in the custom pipeline. Problem: the handle_social_auth function does not work at all. I also set a print function to check if it is working from the console. #settings.py REST_FRAMEWORK = { 'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema', 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ), } SOCIALACCOUNT_PROVIDERS = { 'facebook': { 'METHOD': 'oauth2', 'SDK_URL': '//connect.facebook.net/{locale}/sdk.js', 'SCOPE': ['email', 'public_profile'], 'AUTH_PARAMS': {'auth_type': 'reauthenticate'}, 'INIT_PARAMS': {'cookie': True}, 'FIELDS': [ 'id', 'email', 'first_name', 'last_name', 'middle_name', 'name', 'name_format', 'picture', ], 'EXCHANGE_TOKEN': True, 'LOCALE_FUNC': lambda request: 'en_US', 'VERIFIED_EMAIL': False, 'VERSION': 'v7.0', 'APP': { 'client_id': env.str('FACEBOOK_CLIENT_ID', ''), 'secret': env.str("FACEBOOK_SECRET", '') } }, 'google': { 'SCOPE': [ 'profile', 'email', ], 'AUTH_PARAMS': { 'access_type': 'online', }, 'APP': { 'client_id': env.str('GOOGLE_CLIENT_ID', ''), 'secret': env.str("GOOGLE_SECRET", '') } }, "apple": { "APP": { "client_id": env.str('APPLE_CLIENT_ID', ''), "secret": os.environ.get('APPLE_KEY_ID', ''), "key": os.environ.get('APPLE_KEY_ID', ''), "certificate": SOCIAL_AUTH_APPLE_PRIVATE_KEY, }, } } SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.user.get_username', … -

Can't run a dev server easily
I'm on Windows 11 and I want to create a website with Django. The terminal that I use is Git Bash and I have a problem when I type the command python manage.py runserver. When I type it, it says: Watching for file changes with StatReloader but it doesn't show the typical: Watching for file changes with StatReloader Performing system checks... System check identified no issues (0 silenced).

The thing is that the server works. I just can't access it by copying the link so I run another server and then copy the link that the terminal gave me when I closed the previous server. Right... I don't think I use dockerfiles (I don't even know what it is) Could you tell me how to have the full text by only typing python manage.py runserver and not opening closing and reopening the server again.

Will migrations that I make to a django app reflect on the DB that is present in Kubernetes?
I have a Django application and I'm using MariaDB as the database. Both of them have been deployed to a namespace on kubernetes. Now I want to add an additional field, so I made changes in the models.py file in the django app. These changes were made locally - I pulled the code from GIT and just made the changes locally. Normally to apply the changes, I have to run manage.py makemigrations and manage.py migrate and all the changes would've been reflected on to the DB if the DB was present locally. So now my questions are How can I apply the changes to MariaDb that is there on Kubernetes ? Will running manage.py makemigrations and manage.py migrate locally and redeploying the django app to kubernetes solve this issue ? -

How to serialize a through relationship in django

Heroku not recognising users
Managed to install Heroku today and it looks like some functionality that work perfectly on my local disk are not recognised on Heroku. On my local version: Users that register can leave a comment through a form. When accessing the form, the user that can select their name from a dropdown list and leave a comment against a specific product. ON the Heroku version: the users that are registered on the app are not listed on the comment form. The list is empty. I am happy to post some code, but not sure where to start and would end up copy/pasting a big chunk of code. Have I done something wrong with the upload? Again, the local verison work perfectly fine. So, it must be due to the transfer from Local to Heroku Any pointers? -

How to render an Image from API that returns a file location Django/React

Notify Django Channels websocket from Rest Framework action
My app uses Django Rest Framework for the API. I wanted to add live notifications/status to it. The flow would be User loads page then makes a get API request to load data Websocket connects on page load and subscribes to 'notifications' channel that's in ServerNotifConsumer User clicks a button which sends a POST request to API that does some db stuff that would return success or failure info. Returns status 202 Accepted immediately then processes command. Return info via websocket to all subscribed clients Is there a way from within the DRF viewset action to send anything to the websocket consumer? Or would the best way to go about this be to rewrite the API endpoint to only receive via websocket? (rather not do) -
Long running Celery tasks result in ConnectionResetError: [Errno 104] Connection reset by peer
At my Django application, I use Celery to process very long-running tasks. One of these tasks has to write a record into the database at the very end, to confirm that the process is completed. For some reason if the tasks runs for so long (talking 4 hrs or more here) I get this back: ConnectionResetError: [Errno 104] Connection reset by peer This happens as soon as I trigger a write operation against the Database at the very end of the task, e.g.: Files.objects.filter(pk=files_obj).update ... etc It would be interesting to know why the peer resets the connection (MariaDB in my case). Doesn't Django manage database connections for me using a connection pool? I also checked my Redis config on Django side where in my opinion only these lines really matters: BROKER_TRANSPORT_OPTIONS = {'visibility_timeout': 86400} # 24 hrs. CELERYD_TASK_TIME_LIMIT = 86400 # 24 Hrs. CELERYD_TASK_SOFT_TIME_LIMIT = 86400 # 24 Hrs. Isn't there a way to make the function trigger a new connection or so? To me, it seems that the Celery task keeps the SQL connection alive for as long as the task is running. But the DB backend doesn't respect this for so long. This is how I start … -

send information from a js variable to python
I need to send an object that contains a variable in js, the idea is to be able to send that information to python (I use django) and capture that info to be able to perform the validations that I need from the backend (python) and not from js, how can I do it ? code ajax: function CapturarDatosOrden() { $.ajax({ url: window.location.pathname, type: 'POST', data: { 'action': 'prueba', }, beforeSend: function (jqXHR) { $.xhrPool.push(jqXHR); $(".loader").fadeIn('fast'); }, dataType: 'json', complete: function (jqXHR) { // boton.disabled = false; $('.loader').fadeOut('fast'); var index = $.xhrPool.indexOf(jqXHR); if (index > -1) { $.xhrPool.splice(index, 1); } }, }).done(function (data) { // alert('entro al primer ajax para comparar el tipo de orden y su tecnologia') var info = data.find(data => data.id__ordenes == idOrden); the "info" variable has the object I need to capture in python, the object is something like this: { id__ordenes: "219661981", fk_ot__tipo_orden: "4", fk_bss__contratos: "3257733", otciudad: "1", otdireccion: "----", fk_ot__cc: "1", open_orden: "42588165", instalador: "4320", fk_contratistas__equipos_vendedores: "1", fk_ot__causales: "88" } how can i do it?
