Adding SSL to nginx in docker container on AWS returns connection refused
seeking some help with adding SSL using certbot on Ubuntu 18.04 + nginx. The issue is I get a ERR_CONNECTION_REFUSED error after adding SSL using certbot, I was able access my website (on port 80) before adding SSL. My Django app runs on port 3000 which has been exposed in my Dockerfile and passed in my nginx.conf file as well. docker-compose.yml db: image: postgres uwsgi: restart: always build: . nginx: restart: always image: nginx:latest ports: - "80:80" - "443:443" volumes: - ./nginx.conf:/etc/nginx/conf.d/default.conf:ro - ./uwsgi_params.par:/etc/nginx/uwsgi_params.par:ro - /etc/ssl/certs:/etc/ssl/certs:ro - /etc/ssl/private:/etc/ssl/private:ro redis: restart: always image: redis:latest I have already copied the generated certificates to their respective directories as shown in volumes. nginx.conf server { listen *:80; server_name mydomain.com; return 301 https://$host$request_uri; } server { listen 443 ssl; server_name mydomain.com; root html; client_max_body_size 8000M; client_body_buffer_size 8000M; ssl_certificate /etc/ssl/certs/chained.pem; ssl_certificate_key /etc/ssl/private/domain.key; ssl_session_timeout 5m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA; ssl_session_cache shared:SSL:50m; ssl_dhparam /etc/ssl/certs/dhparam.pem; ssl_prefer_server_ciphers on; location /static { alias /var/www/static; } location ~ (\.php|.aspx|.asp|myadmin) { deny all; } location / { include /etc/nginx/uwsgi_params.par; uwsgi_pass uwsgi:3000; uwsgi_max_temp_file_size 10024m; } } I’ve also updated mydomain.com with my actual domain. -
Saving image after manipulation
I have 2 models. One called Choice and the other called ChoiceImage. class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice = models.CharField(max_length=120) class ChoiceImage(models.Model): choice = models.OneToOneField(Choice, on_delete=models.CASCADE, null=True) img = models.ImageField(upload_to='some-path/') ChoiceImage img takes an ImageField. If the user uploads one image field, then that image is cut in half shown by this function: def slice_image(img): reader = misc.imread(img) height, width, _ = reader.shape with_cutoff = width // 2 s1 = reader[:, :with_cutoff] s2 = reader[:, with_cutoff:] misc.imsave(settings.MEDIA_ROOT + "/" + img.name, s1) return ContentFile(np.ascontiguousarray(s2)) The first image half gets resaved and the second image half gets saved for the second choice. Here's how the logic looks like: class CreateChoiceSerializer(serializers.ModelSerializer): choiceimage = ChoiceImageSerializer(many=False, required=False) class Meta: model = Choice fields = ('choice', 'choiceimage') def create(self, validated_data): image_uploaded = validated_data.get("choiceimage") if not image_uploaded["img"]: q = validated_data.get("question") if not q.choice_set.exists(): raise APIException("You must upload either an image or a cover.") else: img = q.choice_set.all()[0].choiceimage.img img2 = slice_image(img) validated_data["choiceimage"]["img"] = img2 image_validated_data = validated_data.pop('choiceimage') choice = Choice.objects.create(**validated_data) image_serializer = self.fields['choiceimage'] image_validated_data['choice'] = choice image_serializer.create(image_validated_data) It seems everything works fine. The first image gets cut in half and resaved in the media folder, however, the second image does not get saved and has the … -

Django: Serializer VS CustomUserManager
I was wondering, being new to Django and trying different practices, I was wondering whats the difference between using methods with a CustomUserManager and using the similar methods in the serializer. For exemple, I'm creating a User, and to correctly save the password I've put a method using user.set_password() When I'm only using the serializer it looks like this: from rest_framework import serializers from django.contrib.auth import get_user_model from ..models.model_user import * class UserIndexSerializer(serializers.ModelSerializer): class Meta: model = User fields = [ 'id', 'username', 'password', 'first_name', 'last_name', 'email', 'is_a', 'is_o' ] class UserCreateSerializer(serializers.ModelSerializer): class Meta: model = User fields = [ 'username', 'password', 'first_name', 'last_name', 'email', 'is_a', 'is_o' ] extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): user = User( username=validated_data['username'], password=validated_data['password'], first_name=validated_data['first_name'], last_name=validated_data['last_name'], email=validated_data['email'], is_a=validated_data['is_a'], is_o=validated_data['is_o'] ) user.set_password(validated_data['password']) user.save() return user class UserDetailsSerializer(serializers.ModelSerializer): class Meta: model = User fields = '__all__' And when I'm using the CustomUserManager it looks like this: from django.db import models from django.contrib.auth.base_user import BaseUserManager class CustomUserManager(BaseUserManager): def create_user(self, email, password, **extra_fields): """ Create and save a User with the given email and password.

Django Using multiple (two) user types extending AbstractUser
For our project, we have two user types: Donor and Hospital. So we use the User model, which extends the AbstractUser model. The Donor and Hospital models both have OneToOneField relationship with the User and it uses the default user authentication. Almost everything works fine. The Donor and Hospital creation works well, the instances are added to the database and we can log in. However, we need the Donor object and its fields in the view and in the template. We have the user contained in the request and the id of the user. donor = Donor.objects.get(pk=request.user.id) Or donor = Donor.objects.filter(donor=request.user).first() Should return the donor object, but it returns None. It works for Hospital. If we do Donor.objects.all() the newly created Donor is not in the list. However, created hospital is present in the list. We cannot figure out what is the problem, the ids for donor and user do not match. Thank you very much for your help! These are our models: class User(AbstractUser): is_donor = models.BooleanField(default=False) is_hospital = models.BooleanField(default=False) class Donor(models.Model): # username, pword, first+last name, email donor = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) # donor_id = models.IntegerField(auto_created=True, unique=True, null=False, primary_key=True) nickname = models.CharField(max_length=40, unique=True) phone = models.CharField(max_length=10) address = … -

Django Login POST hangs when i do HttpResponseRedirect (302)

When I do "POST" of username/password Form (passes authenticate() and login() well) and have to redirect (HttpResponseRedirect) to my index page, the browser hangs waiting for a response (it stays in the login page).
