Django web app: storing Chat messages in database
I am creating a web app using Django and would like to allow any 2 users (but only 2 at a time) to be able to chat with each other. It doesn't need to be anything fancy and it will only be between the 2 related users on a Transaction object, so the Chat object will look up to the Transaction object. Someone told me it's not a good idea to store chat messages in just a regular Message table in a database, and that I should use a messaging service, since the chat messages would not be encrypted in the database. The chat messages will allow 2 users to plan to meet up with each other, which is somewhat confidential, but I don't think it's anything to worry about. Or am I wrong? I was also considering using the django-messages library, but I think it would be easier to just add a new object to my table. I found this StackOverflow post from 10 years ago about how this solution is good but didn't find many discussions about this recently. Below is a picture of the schema suggested: enter image description here What do people think, is it better … -

Why do we direct the urls file in our main directory to the newly created urls file in the app directory in Django?
I was learning Django and noticed people directing the URLs file in the main directory of the project to a new created URL.py file in the app folder? Why can't we directly put the path in the URL file in the main directory? Instead of using include, we could have directly put the path there. Why aren't we doing it? -

Passing dynamic url with parameters from JavaScript to Django
I have this form for adding and updating data: form.addEventListener('submit', function(e){ e.preventDefault() var url = "{% url 'api:task-create' %}" if(activeItem != null ){ url = `http://localhost:8000/api/task-update/${activeItem.id}/` activeItem = null } var title = document.getElementById('title').value fetch(url, { method: 'POST', headers:{ 'Content-type': 'application/json', 'X-CSRFToken': csrftoken, }, body: JSON.stringify({'title':title}) }).then(function(response){ renderList() document.getElementById('form').reset() }) }) when adding url without parameters like this {% url 'foo:bar' %} it works fine, but when I do this: {% url 'foo:bar' <any var> %}, I am getting NoReverseMatch error. Currently I am using static url as you can see up top inside if statement and it works perfectly fine. I tried using ` to make it literal string still doesnt work.

DRF Login/logout with Token authentication possibly with Session Authentication
I am beginner in django and I am trying to use Basic and Token Authentication for Login/logout views referring below tutorial except that I have own function based view. https://gutsytechster.wordpress.com/2019/11/12/user-auth-operations-in-drf-login-logout-register-change-password/ I use django.contrib.auth authenticate in to check for user credential and return a token instead of login method which I suppose creates a session in django. But the tutorial asks for auth.logout method for logging out which would require HTTPRequest object instead of rest_framework.Request object. However it works for logout and when I try to use auth.login method it give me the following error. The request argument must be an instance of django.http.HttpRequest, not rest_framework.request.Request my understanding is that django.contrib.auth methods login, logout works with session authentication and rest_framework.Request extends HTTPRequest. My questions are Does this error happens as I dint set up session authenticationin middleware? if so why logout alone works? Shouldn't it throw the same error for not referring to HTTPRequest object. Any help would be appreciated as I try to understand the basics well before going for any other approach. My view here @api_view(["POST"]) def login(request): serializer = LoginSerializer(data=request.data) serializer.is_valid(raise_exception=True) user = get_and_authenticate_user(**serializer.validated_data) data = AuthUserSerializer(user).data #login(request, user) return Response(data=data) def get_and_authenticate_user(username, password): user = authenticate(username=username, password=password) … -
Django - Group permissions per vendor or company
I am using a custom User model. I would like to enforce permissions based on vendor and group. A vendor can create groups and assign those groups permissions from given list of permissions. I have been reading about group permissions and have concluded that Django's Group model is not good choice for this as it doesn't allow multiple groups with same name and some other issues. I looked into some projects like Django-guardian. But don't seem to get an example that fits my case. What I want to do is. A Vendor will have staff users who will then be assigned to groups. So to check permission for a given group or user I will need to take Vendor into consideration. They must be member of the vendor staff and then the permission group. Can anyone point me in the right direction. Thank you -
nginx 502 error on digitalocean after copying code from dev folder to mail folder
I have a Django app deployed on DigitalOcean with Nginx, PostgresSQL. I have copied my code from my main folder to another dev-folder, so initially, both the folders have the same code. Now, I run python manage.py runserver 0.0.0.0:8000 in my def-folder and can access my application on https://server_ip:8000/. Now, I can make any changes in my code without affecting the main application. Once changes are done, I run cp -a /source/. /dest/ to copy my changes from the dev-folder to the main folder. It all looks good, but after copying code from the dev-folder to the main folder, my application gives a 502 error. The error disappears after running systemctl restart gunicorn. But why nginx is giving 502, when there is no timeout issue. Also, is this the accepted way of maintaining dev branch?? -

Django serilizator object updating problem
i would like to ask where could be problem with my serilizator or calling of him. I want to update serializated data inside object personal info but it keep throwing me error: AttributeError: 'PersonalInfoSerializer' object has no attribute 'user' Here's my serilizator class: class PersonalInfoSerializer(serializers.Serializer): user = serializers.IntegerField(required=False) firstname = serializers.CharField(max_length=255) lastname = serializers.CharField(max_length=255) card_id = serializers.CharField(max_length=255) street = serializers.CharField(max_length=255) postal_code = serializers.IntegerField() city = serializers.CharField(max_length=255) debet_card_number = serializers.CharField(max_length=16) created_at = serializers.DateTimeField(required=False) last_update = serializers.DateTimeField(required=False) def create(self, validated_data): return PersonalInfo.objects.create(**validated_data) def update(self, instance, attrs): print("instance", attrs.get('user', instance.user)) instance.user = attrs.get('user', instance.user) instance.save() return instance And here is my view function thats updating serilizator object: json = BytesIO(request.body) data = JSONParser().parse(json) data.update({'created_at': datetime.datetime.now(tz=timezone.utc), 'last_update': datetime.datetime.now(tz=timezone.utc), 'last_login': datetime.datetime.now(tz=timezone.utc), 'token':generate_key()}) user = UserSerializer(data=data) personal_info = PersonalInfoSerializer(data=data) if user.is_valid() and personal_info.is_valid(): if user_exists(data["email"]): response = {'Failed': 'email is already used'} return JsonResponse(response) elif card_exists(data["card_id"]): response = {'Failed': 'card id is already used'} return JsonResponse(response) else: user.save() personal_info = PersonalInfoSerializer(personal_info, {'user':10}, partial=True) personal_info.is_valid() personal_info.save() I think main problem is calling serilizator update but i tried everything :/ Thank you for help :) -
