How can I get Django to send error emails on status codes above 500?
I have migrated an old codebase to a new server and am now running Django 4.0.5. I can send emails from the shell as follows: from django.core.mail import mail_admins mail_admins(subject='test', message='test') But I don't receive any emails on 500 or higher errors. My settings are: DEBUG = env('DEBUG') ADMINS = [('My Name', 'me@provider.com'),] MANAGERS = ADMINS ADMIN_EMAIL = ['me@provider.com',] DEFAULT_FROM_EMAIL = 'admin@provider.com' SERVER_EMAIL = 'admin@provider.com' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_HOST_USER = 'admin@provider.com' EMAIL_HOST_PASSWORD = env('EMAIL_HOST_PASSWORD') EMAIL_USE_TLS = True And i have tried adding: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' But they are still not sent. I am using django-environ, but debug is set to false. Any ideas what the problem could be? -

Django: create many-to-Many relationship without creating intermediary table
I have a set of tables that Ive turned into django models. The tables weren't architected very well and i can't change them, and it is causing problems for this one many to many relationship I'm trying to set up in my code. Models class Owner(models.Model): owner_uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, unique=True) # Field name made lowercase. email = models.TextField(max_length=200, unique=True) is_active = models.BooleanField( blank=True, null=True) # Field name made lowercase. owned_apps_whistic = models.ManyToManyField("Applications", through="ApplicationOwnerXRef", related_name="owners_whistic") #owned_apps_group = models.ManyToManyField("Applications", through="BusinessUnitOwnerXref", related_name="owners_group") class Applications(models.Model): application_id = models.UUIDField(primary_key=True) url = models.TextField(blank=True, null=True) name = models.TextField(blank=True, null=True) service = models.TextField(blank=True, null=True) status = models.TextField(blank=True, null=True) created_date = models.TextField(blank=True, null=True) description = models.TextField(blank=True, null=True) business_unit_name = models.TextField(blank=True, null=True) class BusinessUnitOwnerXref(models.Model): id = models.AutoField(primary_key=True) owner_uuid = models.ForeignKey(ApplicationOwner, models.DO_NOTHING, to_field="owner_uuid", db_column = "owner_uuid") business_unit_name = models.TextField(max_length=100, null=True) Owners can own applications by owning the group that owns the application, indicated in the BusinessUnitOwnerXref table. The Application table and the BusinessUnitOwnerXref both have the business_unit_name column , and can be directly joined I cant use a foreign key because the BusinessUnitOwnerXref.business_unit_name column isn't unique. TLDR, Is there a way to create the many-to-many relationship between Applications and Owners, through BusinessUnitOwnerXref, without altering the existing tables or letting django … -

Django service only works when the image is deleted and pulled again (in Swarm)
I have a swarm cluster with 2 workers and one manager. I built a Django image, pushed it to Docker Hub. I make migrations before pushing the image so it contains them. I pull the image for it to be used for the Swarm services, using docker-compose, I deploy the stack, everything works. But if I remove the stack and try to start it again from the old image (which should be immutable) i get psycopg2.OperationalError: could not translate host name "db" to address: Name or service not known. If I delete the image and just run the stack again (so basically I get the same image from Docker Hub) the service is deployed without any errors. So i cant delete the stack and use the same image to deploy it again..

Django Template request.GET.value don't work

It seems as if my local dev env is not finding a table in the mysql database but I don't think it's actually connecting at all since my coworkers aren't receiving the same error. -
Forms django -> is_valid
i'm currently developping an application on django and when i send a post request from a form, is_valid method return false. my forms.py : from django import forms class formadduser(forms.Form): mail = forms.CharField(label='Mail', max_length=40) # imput_username = forms.CharField(input='input_username', max_length=100) prenom = forms.CharField(label='Prénom', max_length=25) # input_password = forms.CharField(input='input_pathword', max_length=100) nom = forms.CharField(label = 'Nom', max_length=25)
