How to use elasticsearch for mutiple models in Django using the same search api
I am trying to implement an elastic search in Django for multiple models in a single search api. If I had to implement using different apis I can do in the following way. my models.py class Category(models.Model): name = models.CharField(max_length=32) description = models.TextField(null=True, blank=True) class Meta: verbose_name_plural = 'categories' def __str__(self): return f'{self.name}' ARTICLE_TYPES = [ ('UN', 'Unspecified'), ('TU', 'Tutorial'), ('RS', 'Research'), ('RW', 'Review'), ] class Article(models.Model): title = models.CharField(max_length=256) author = models.ForeignKey(to=User, on_delete=models.CASCADE) type = models.CharField(max_length=2, choices=ARTICLE_TYPES, default='UN') categories = models.ManyToManyField(to=Category, blank=True, related_name='categories') content = models.TextField() created_datetime = models.DateTimeField(auto_now_add=True) updated_datetime = models.DateTimeField(auto_now=True) def __str__(self): return f'{self.author}: {self.title} ({self.created_datetime.date()})' my serializers.py class CategorySerializer(serializers.ModelSerializer): class Meta: model = Category fields = '__all__' class ArticleSerializer(serializers.ModelSerializer): author = UserSerializer() categories = CategorySerializer(many=True) class Meta: model = Article fields = '__all__' views.py class CategoryViewSet(viewsets.ModelViewSet): serializer_class = CategorySerializer queryset = Category.objects.all() class ArticleViewSet(viewsets.ModelViewSet): serializer_class = ArticleSerializer queryset = Article.objects.all() documents.py @registry.register_document class CategoryDocument(Document): id = fields.IntegerField() class Index: name = 'categories' settings = { 'number_of_shards': 1, 'number_of_replicas': 0, } class Django: model = Category fields = [ 'name', 'description', ] @registry.register_document class ArticleDocument(Document): categories = fields.ObjectField(properties={ 'id': fields.IntegerField(), 'name': fields.TextField(), 'description': fields.TextField(), }) type = fields.TextField(attr='type_to_string') class Index: name = 'articles' settings = { 'number_of_shards': … -

How to filter by field in django rest framework class based views
I have an app (class based views) with content in many languages and I want to give the option to filter by language in my endpoint like this: localhost:8000/api/resources/?language=ES This is my JSON data: { "id": 10, "contents": [ { "id": 5, "language": "EN", "name": "First" }, { "id": 6, "language": "ES", "name": "Primero" } ], "created_at": "2022-08-07T20:27:16.581115-05:00", "updated_at": "2022-08-07T20:27:16.581115-05:00" } What is the most elegant way of doing this? -
how do i change the language prefix to the user stored prefered language
I am working on a multilanguage Django project and i am using i18n for that, what i want to do is store the user-preferred language, I have already done that and added a language field in the User model, so my approach to solve this problem was creating a middleware to change to the user preferred language: from Django.utils import translation class LanguageMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): if request.user.is_authenticated and request.user.language: translation.activate(request.user.language) else: translation.activate(translation.get_language()) response = self.get_response(request) return response and I set the user language to 'ar', but if I try to enter with the URL 127.0.0.1:8000/en it doesn't work as expected and gives me this 1.ar/ The current path, en/, didn’t match any of these. but what I wanted is to redirect it to this 127.0.0.1:8000/ar either from this 127.0.0.1:8000 or this 127.0.0.1:8000/en and of course, that will be based on the preferred language, and if the user is not authenticated it will be just based on the language data in the request, how can I do that please? -
CS50 Project 1 Help - Wiki Search w/ Django - Stuck on how to save a new page
So I am creating my Wiki Search Page with Django and everything is going fine so far. I am now stuck on how to create a new entry in my search encyclopedia. On my home bar the "Create new Page" link works fine and takes me to a new page where I can create a new entry. The problem is when I try and save the entry into my encyclopedia I get this message: ValueError at /new/ The view encyclopedia.views.new didn't return an HttpResponse object. It returned None instead. I think it is a problem in my views.py section but can't seem to figure it out. Here is my views.py def new(request): if request.method == 'GET': return render(request, "encyclopedia/new.html", { "create_form": CreateForm(), "search_form": SearchForm() }) file_content = request.POST.get("content","") file_title = request.POST.get("title", "") if (len(file_content) == 0 or len(file_title) == 0): return render(request, "encyclopedia/error.html", { "message": "Bad Request", "description": "Title and content cannot be empty", "status": 400 }) if util.get_entry(file_title): return render(request, "encyclopedia/error.html", { "message": "Bad Request", "description": "This page already exists", "status": 400 }) Everything with the page works fine. I get the correct error when trying to save the page without any entry. The problem is it just won't … -
Overriding Django's default id in it's User Model
We have a working Django project in a multi-master database environment. That means the we have multiple instances of the project's database running in separate machines and that all individual changes are propagated to the other databases. Is working very well in this setup and without any issues. Up to now, we were not using Django's Auth tooling, meaning that there was not user login or password. That has to change. For this to work in our replication environment, thou, we need to change User's default id to something akin of a UUID to avoid collisions when the replications occurs. So, the challenge at hand is this: how to change the id field of the User model in the Auth App? We don't have any other specific requirement except this. We don't need any extra field and anything. Just to change the id. In the case that writing our own custom User model is inescapable maybe someone could point us at some good blog post about it or share any other resource. Ideally we would like to preserve everything else. including access to admin's interface, groups and permissions. Thanks in advance -

How can I send a message to all posts in Django Allauth?

Application Load Balancer Health Django Elastic Beanstalk Barebones

Anyways, why does this not work "OUT OF THE BOX" like the Classic Load Balancer? What do I need to configure as the docs are all over the place (and outdated)?

Django Migration to add Group and permissions not adding permissions
I have a custom migration that is intended to automatically create a new group and add permissions. The group is being created but the permissions are not being added.
