SMTPServerDisconnected at /auth/users/
I am currently working with Python 3.10.0 and Django 4.0 on the back end, and React/Redux on the front end. I have an app where after a user signs up, an activation email will be sent. However, the email never shows up and while visiting the backend, I see this error inside the network tab in devtools. I switched from gmail due to the work arounds that ended up not working for me so I went with SendGrid, but haven't gotten that to work yet either. From all of the posts I have seen so far, this looks right. settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.sendgrid.net' EMAIL_HOST_USER = 'api' EMAIL_HOST_PASSWORD = 'password' DEFAULT_FROM_EMAIL = 'email@gmail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True auth.js // sign up function export const signup = (email, password, re_password) => async (dispatch) => { const config = { headers: { 'Content-Type': 'application/json', 'X-CSRFToken': csrftoken, }, }; const body = JSON.stringify({ email, password, re_password }); try { const response = await axios.post( `${process.env.REACT_APP_API_URL}/auth/users/`, body, config ); dispatch({ type: SIGNUP_SUCCESS, payload: response.data, }); } catch (err) { dispatch({ type: SIGNUP_FAIL, }); } }; -

Own django tokens authentication
I would like to have standard super user in Django app. On the other side, I have to make login system and authentication system for "users of myapp" (generate and using tokens for rest requests). So do I have to inheritate User class with my models class Worker or I can make to use tokens without that. I think that this would make that everyone can access to system as super user, because every user I make would be super user, or I have to give him some privileges? Is this necessary to inheritate AbstractBaseUser class: class Worker(AbstractBaseUser): username = models.CharField(max_length=30, unique=True, default="user") password = models.CharField(max_length=300, default="password") company = models.ForeignKey(Company, on_delete=models.RESTRICT) workerName = models.CharField(max_length=50) workerSurname = models.CharField(max_length=50) workerPhoneNumber = models.CharField(max_length=30) Or, is there any way to generate and use tokens with Worker objects, and to separate Worker accounts from super user admin account? -
Google Cloud Run, Django and "no such table" during build
I am following this tutorial to upload my existing Django project running locally on sqlite to Google Cloud Run / Postgres. I have the cloud_sql_proxy service running and can sign into Postgres. I am at the point of running the command gcloud builds submit --config cloudmigrate.yaml \ --substitutions _INSTANCE_NAME=INSTANCE_NAME,_REGION=REGION It runs for a while making good progress but then fails with: Step #2 - "apply migrations": django.db.utils.OperationalError: no such table: registration_setting Finished Step #2 - "apply migrations" ERROR ERROR: build step 2 "gcr.io/google-appengine/exec-wrapper" failed: step exited with non-zero status: 1 I do have a settings table in my registration app. But I don't understand where its missing from. Is this just the first table it's trying to create? Do I have to do something first to have it create the initial tables in Postgres? When I inspect Postgres I don't see any tables created in it. I tried wiping out my migration and pycache folders and recreating them. -
Use django-taggit package with graphene mutations
I'm using the package django-taggit with graphene-django. Initially, I was getting the error specified in this question (Don't know how to convert the Django field skills (<class 'taggit.managers.TaggableManager'>); but thanks to the answers there, I resolved the issue.

How to log production database changes made via the Django shell
I would like to automatically generate some sort of log of all the database changes that are made via the Django shell in the production environment. Our code base is version controlled so if we introduce a bug, it's easy to track it back. But if a developer in the team changes the database via the Django shell which then introduces an issue, at the moment we can only hope that they remember what they did or/and we can find their commands in the Python shell. I'm particulalry interested in a solution that works with Python/Django. Ideally we would log also the Python code that triggered the data change. -

Django Rest Framework OAuth2 Access Token Guidance Required
I'm trying to implement OAuth and jwt token login in Django Rest Framework for practice. I'm using social-auth-app-django and djangorestframework_simplejwt. I use the basic documentation and successfully created a user using GitHub (Checked that in Django Admin) and I also created a user using Simple CreateAPIView. For login purposes, I can use simple jwt to login and retrieve the access token to call the other authenticated APIs, but how can I do the same using an OAuth logged-in user account. Another problem I'm facing is, whenever to visit http://localhost:8000/api/auth/login/github/ in the browser is prompts my login screen, after login, it redirects me to http://localhost:8000/api/auth/complete/, which returns 404 because it's not the right endpoint as per the Django default error page. It represents api/auth/complete/<str:backend>/ [name='complete'] as one of the available endpoint. When I visit /api/auth/complete/github/ the error that comes up is AuthMissingParameter at /api/auth/complete/github/. I don't have any idea what is happening. My settings.py configurations are: INSTALLED_APPS = [ --- # Plugins "rest_framework", "corsheaders", "oauth2_provider", "social_django", "rest_framework_social_oauth2", --- ] REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": ( "oauth2_provider.contrib.rest_framework.OAuth2Authentication", "rest_framework_social_oauth2.authentication.SocialAuthentication", "rest_framework_simplejwt.authentication.JWTAuthentication", ), } AUTHENTICATION_BACKENDS = ( "rest_framework_social_oauth2.backends.DjangoOAuth2", "django.contrib.auth.backends.ModelBackend", "social_core.backends.github.GithubOAuth2", "social_core.backends.spotify.SpotifyOAuth2", "django.contrib.auth.backends.ModelBackend", ) -

how to render data in django template that has been queried in backend using "__contains"

How to run my local django server using poetry
I am new to python/django and I am coming into an existing codebase that uses the package manager poetry. My question is simple; how do I start my local django server using poetry run? If not using poetry I understand I can just use python manage.py runserver, but when I run that in my project, I get ImportError: No module named django.core.management. The other most relevant command I ran was poetry run python manage.py runserver, but that yielded ModuleNotFoundError: No module named 'django_q'. I am literally just trying to figure out how to run poetry commands, and in this instance, start my local django server. I am decently lost, so any help with django/poetry would be very helpful.
