Parse user input to show as html code. Python + Django
I have Publication class with field for input tags. I capture it with POST method. The problem is that I can not parse it correctly to be able to use those tags as follows {% for item in tags_string %} {{ item.tag }} {% endfor %} How do I format this tags_string so django understands it. I tried to make a QuerySet using next method, and building a list of dictionaries result = [] for a in tags.split(): tag_entry = { 'tag' : a, } result.append(product_entry) As a result I receive a line [{'tag': 'sky', 'tag': 'mountain'}] But my page doesn't show anything using mentioned code block. -

Cannot generate django.po files from docker-compose
I'm using Django 3.0.5 inside of a docker-container, linked to an Postgres-container.

Serializers validation - TypeError... 'UniqueTogetherValidator' object is not iterable
I have a model called 'following' where one user can follow another, using the Django rest framework. I am trying to implement a validation so that you can't follow someone twice, and trying the built-in UniqueTogetherValidator. Here are the relevant parts of my models.py class Following(models.Model): user = models.ForeignKey('User', related_name='user', on_delete=models.CASCADE) follower = models.ForeignKey('User', related_name='follower', on_delete=models.CASCADE) And serializers.py: class FollowingSerializer(serializers.HyperlinkedModelSerializer): user = serializers.CharField(source='user.username') follower = serializers.CharField(source='follower.username') class Meta: model = Following fields = ['user', 'follower'] validators = UniqueTogetherValidator( queryset = Following.objects.all(), fields = ['user', 'follower'], message = "You are already following that person!" ) I have some existing data: HTTP 200 OK Allow: GET, POST, HEAD, OPTIONS Content-Type: application/json Vary: Accept { "count": 2, "next": null, "previous": null, "results": [ { "user": "mike", "follower": "chelsea" }, { "user": "mike", "follower": "chloe" } ] } When I try to add any new following object using the API interface, I get this error: TypeError at /followings/ 'UniqueTogetherValidator' object is not iterable Request Method: POST Request URL: http://127.0.0.1:8000/followings/ Django Version: 3.0.5 Exception Type: TypeError Exception Value: 'UniqueTogetherValidator' object is not iterable ...

Filtering in Django ModelViewSet
I don't think I'm doing this correctly. What I'm trying to do is prevent data from being returned if it doesn't match my criteria. Here are the criteria: User should be able to see the project if: If the object is private and they are the owner -- OR -- The project is not private If the user is the owner, or they are a member of the assigned group As far as I can tell, it's not getting the data into the is_private and owner variables I set. Every tutorial I read online though seems to do it in this way. So I'm pretty lost right now. class ProjectListViewSet(viewsets.ModelViewSet): queryset = Project.objects.all().order_by('name') serializer_class = ProjectLightSerializer authentication_classes = [TokenAuthentication, ] permission_classes = [IsAuthenticated, ] def get_queryset(self): queryset = super().get_queryset() is_private = self.request.data.get('is_private') owner = self.request.data.get('owner') print(is_private) print(owner) if is_private: if owner == self.request.user.id: queryset = queryset.filter(owner__exact=self.request.user) else: if owner == self.request.user.id: queryset = queryset.filter(owner__exact=self.request.user) else: queryset = queryset.filter(groups__in=self.request.user.groups.all()) return queryset Any assistance would be greatly appreciated. Thanks in advance. -
How to work with external API from Django admin
I have a problem to solve with Django. I need in some way from the admin area to be able to use an external API to do some HTTP requests, GET and POST. I'm not sure how a good approach would be to solve this. I have only handled this on the frontend before. I should be able to get a list of orders from the API, update an order, get a specific order with details, post a new order etc. I'm thinking such as when you register a model and then registering it with ModelAdmin, would that be possible to use the API to load it in similar way there and handle the API? Should I store the API data in a model to a database? Should I create create a custom made Django admin page? Other ideas? -

Djoser return access and refresh token when registering user
I am trying to get access and refresh tokens when the user registers using the /auth/users/ endpoint. I have already extended the serializer and it is showing all custom fields. It registers the user successfully and returns the result as follows: { "mobile": "12345", "driving_id": "478161839", "full_name": "John Doe", } This is where I would want to have an access and refresh token. I read that djoser uses django simple jwt library to provide access and refresh tokens. This is the function to create the tokens manually which I am able to do but the only thing I am not understanding is where to return the data with other details. from rest_framework_simplejwt.tokens import RefreshToken def get_tokens_for_user(user): refresh = RefreshToken.for_user(user) return { 'refresh': str(refresh), 'access': str(refresh.access_token), } -

Amazon SNS topic,subscription and geo-localized push notifications management for mobile devices
I have one Django application with some REST-services. I store mobile devices geo-location and I have to send a push notification (the same push notification) to all devices that they are into a specific location (with a certain radius). I'm using AWS-SNS service and I already registered the mobile on SNS. I would like to not use some asynchronous architectures (for example Celery) to retrieve all devices, that they are into the location to send, for each of these, the push notification (one request to SNS for each device). For example, I'm searching for a way to register all retrieved devices on a topic-subscription in bulk and, after this, on request to send the push notification to all devices that they are registered to this topic. My goal (best case) can be: Retrieve all devices by geo-location; Create an SNS topic dedicated for this request; One request to store in bulk these devices for this topic; One request to send the push notification for this topic; This is a possible approach for example. I would like to reduce the request to SNS and I would like to not use (for example) Celery to create different async steps for this. Is … -

How to change button text onclick using django?
I'm working on a school project and I'm trying to change a button's innerHTML to a value I got from a dictionary in views.py. However, when I load the page with this code: <script> var docFrag = document.createDocumentFragment(); for (var i=0; i < 3 ; i++){ var row = document.createElement("tr") for (var j=0; j < 3 ; j++){ var elem = document.createElement('BUTTON'); elem.type = 'button'; elem.id = 'r'+i+'s'+j; elem.value = 'r'+i+'s'+j; elem.onclick = function () { document.getElementById("klik").value = this.id; document.getElementById("ID").value = this.id; document.getElementById("klik").submit(); var id = this.getAttribute('id'); var novi = document.createElement('BUTTON'); novi.type = 'button'; //alert("This object's ID attribute is set to \"" + id + "\".") novi.value = id; novi.innerHTML = {{vrijednost}}; this.parentElement.replaceChild(novi,this); }; elem.innerHTML = elem.value; docFrag.appendChild(elem); } document.body.appendChild(docFrag); document.body.appendChild(row); } </script> Nothing happens.

Firebase and Django API
I'm want to start coding web platform(and perhaps later also make a mobile app for iOS and Android) and I recently started considering using Firebase. I really want to use its auth system, database system, and file storage system. I'm not really good at DevOps and I feel like Firebase can really make my life better. I want to use Django to create API and React with Next.js for frontend. API will have to do a few things with data, manage user's access, and their possible actions. I'm confused after all I've read on the internet about Firebase. 1. My frontend and backend have to be hosted somewhere else or can I host them on Firebase. 2. Is it even possible to create a fully working API that uses Firebase systems? Would such a thing be efficient? And how could I do that? And the most important question: Is using Firebase like that expensive? Will I not overpay? Maybe some of you have actual commercial experience with Firebase. -
