DRF is not updating the database
Here's the model: from django.db import models from datetime import datetime, timedelta # Create your models here. def set_expiration(): return datetime.today().date() + timedelta(days=30) class Customer(models.Model): email = models.EmailField(max_length=254, unique=True) created_on = models.DateField(auto_now_add=True) expires_on = models.DateField(editable=False, default=set_expiration()) def __str__(self): return self.email And this is the view: @api_view(['POST']) def update_customer(request): try: customer = Customer.objects.get(email=request.data['email']) except ObjectDoesNotExist: return Response(status=status.HTTP_404_NOT_FOUND) serializer = CustomerSerializer(instance=customer, data=request.data) if serializer.is_valid(raise_exception=True): serializer.save() return Response(serializer.data) And the serilizer: from rest_framework import serializers from .models import Customer class CustomerSerializer(serializers.ModelSerializer): class Meta: model = Customer fields = '__all__' At this moment I have a record in database with expires_on set to 2022-03-14 and I want to update that to 2024-12-12 so I call the endpoint with the following data: { "email": "myemail@mydomain.com", "expires_on": "2024-12-12" } The view returns this: { "id": 1, "email": "myemail@mydomain.com", "created_on": "2022-02-12", "expires_on": "2022-03-14" } This is the existing data. expires_on is not updated with the new value. I get no error and no exception. It just doesn't work. -
Unabled to deploy django + apache on aws Ubuntu server
I am trying to deploy a Django Application using Apache on an Ubuntu Server, I am having a weird error (500 internal error server error) when using port :80. I made some test using port :8000 running the command: python3 manage.py runserver 0.0.0.0:8000 And the application is working without any problem there, but when I try to access the application using port 80 it does work. My apache config file looks like this: <VirtualHost *:80> Alias /static /home/ubuntu/gh_system/static <Directory /home/ubuntu/gh_system/static> Require all granted </Directory> <Directory /home/ubuntu/gh_system/HRSYSTEM> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess HRSYSTEM python-home=/home/ubuntu/gh_system/env python-path=/home/ubuntu/gh_system> WSGIProcessGroup HRSYSTEM WSGIScriptAlias / /home/ubuntu/gh_system/HRSYSTEM/wsgi.py -
