Django got a new redirect after receiving the response I tried to solve this problem with Django, but I can't do 2 redirects in one view -
Save a model in the database with multilevel nested serializers in Django
i need help with my rest Api,with Django rest Framework and Django 4. My Api is for reading texts in foreign language, i'm trying to save a new MyTexts model in the database (Sqlite). I think the problem comes from the serializer TextSerializer. I have these models and serializers(correct them if they are wrong): #language/models.py from django.db import models # Model for a Language class Language(models.Model): LgName=models.CharField(max_length=40) LgDict1URI=models.CharField(max_length=200) LgDict2URI=models.CharField(max_length=200) LgGoogleTranslateURI=models.CharField(max_length=200) LgExportTemplate=models.CharField(max_length=1000) LgTextSize=models.IntegerField() LgRemoveSpaces=models.BooleanField() LgRightToLeft=models.BooleanField() LgSkills=models.TextField() def __str__(self) -> str: return self.LgName #language/serializer.py from rest_framework import serializers from .models import Language class LanguageSerializer(serializers.ModelSerializer): class Meta: model=Language fields='__all__' #learner/model.py from django.db import models from django.contrib.auth.models import AbstractUser from language.models import Language # Model for a Learner(a user) class Learner(AbstractUser): SelLanguage=models.OneToOneField(Language,on_delete=models.CASCADE,null=True,related_name="SelLanguage") is_teacher=models.BooleanField(default=False) can_post=models.BooleanField(default=False) level=models.IntegerField(default=0) def __str__(self) -> str: return self.username #learner/serializer.py from django.contrib.auth import authenticate, get_user_model from rest_framework import serializers from language.models import Language from language.serializers import LanguageSerializer from .models import Learner User = get_user_model() class UserSerializer(serializers.ModelSerializer): SelLanguage=LanguageSerializer(many=False,read_only=True) def create(self, validated_data): SelLanguage = validated_data.pop('SelLanguage') user = Learner.objects.create(**validated_data) lg=Language.objects.get(Learner=user, **SelLanguage) user.SelLanguage=lg user.save() return user class Meta: model = Learner fields = '__all__' #myTags/models.py from tkinter import CASCADE from django.db import models from accounts.models import Learner from language.models import Language # Model for optional tags … -
How to integrate novnc client inside django project
I have a couple virtual machines running inside proxmox but I found out you can use the novnc client to connect to these virtual machines and use the console in a web browser. This is perfect for different clients I work with. I already have a small django project that shows the running nodes and vm's inside of them. Now I wanted to include de js library by novnc. However I can't really find a lot of information online and since my coding experience is not that high I don't really know what I am doing wrong. I used this outdated repo and tried to see if I can find out how to get it to work. https://github.com/missuor/novnc-proxy-django for now I have a view that call the api of proxmox. /api2/json/nodes/{node}/lxc/{vmid}/vncproxy to be precise. this returns a ticket, port, cert, user and upid. Now I am not sure if I just need to call the vncproxy or use these variable to open a websocket by /api2/json/nodes/{node}/lxc/{vmid}/vncwebsocket. The django view i currently have just call the vncproxy and sends the values to the rendered template. This template I used from the repo metioned above, but I just don't know why I … -
Queryset for search by username and display_name In Django Rest Framework
I'm trying to search users by their usernames and display names. I have used that for the starting match. search_obj = User.objects.exclude(user_uuid=token_user_uuid).filter(Q(display_name__istartswith=search_name) | Q(username__istartswith=search_name) ).order_by('-created_on')[:10] I get the answer same as I want but the problem is if the display name is William Welch and I search for Welch It should return that user also, but it does not return that user. -
Calling a model's method inside a serializer and handling a received object
I'm supposed to write an API for the endpoints. It should be an application inside an existing project. I should work with its models and i'm not allowed to alter them in any way. The project consists of multiple application, and some application have their own models. There is an exempt from CategoryMetall/models.py in the CatalogNew application: class CategoryMetall(MPTTModel): position = models.ForeignKey( Menu, on_delete=models.CASCADE, verbose_name="foo", blank=True, null=True, ) subPosition = TreeForeignKey( "self", on_delete=models.CASCADE, verbose_name="bar", blank=True, null=True, ) def parent(self): if self.subPosition: return self.subPosition else: return self.position As i understood, the parent() method is supposed to return an object of either a CatalogNew model, or a Menu model. A Menu model is a model of another application from the project. Here is an exempt from it as well: Menu/models.py class Menu(models.Model): parent = models.ForeignKey( "self", on_delete=models.CASCADE, verbose_name="parent category", null=True, blank=True, ) So, i figured that in order to get a parent category i'm supposed to use the CategoryMetall.parent() method written by some other developer. The issue is, i'm also supposed to somehow serialize it. I have written a serializer in my serializers.py: class CategoryMetallSerializer(serializers.HyperlinkedModelSerializer): parentCategory = serializers.ReadOnlyField(source='parent') class Meta: model = CategoryMetall fields = ['id', 'name', 'parentCategory'] And a view for … -
Hosting Django Docker Postgres on DigitalOcean Droplets
I am new to deploying to DigitalOcean. I recently created a Droplet, into which I will put my Django API to serve my project. I saw that the droplet I rent has 25 GB of memory, and for the actual size of my project, it could be a good fit for the database. I run my entire code with Docker Compose, which handles Django and PostgreSQL. I was wondering if it is a good idea to store all the data in the PostgreSQL created by Docker Image, and stored in the local memory of the droplet, or do I need to set up an external Database in Digital Ocean? Technically I think that could work, but I don't know if it is safe to do, if I will be able to scale the droplets once the size scales, or if I will be able to migrate all the data into an external database, on digital ocean, a managed PostgreSQL all my data without too many problems. And if I save it all locally, what about redundancy? Or can I clone my database on a daily basis in some way? If someone knows about that and can help me, please I … -

Can I provide automatically current user in Django rest API like this?
I have a Django rest api. In my model I have a user as a foreign key. When I do a post with the, I do not want that the user needs to provide his own user. But if the user does not provide his user credentials, the serializer won't be valid and then won't be saved. I have found that we can access to serialized dat before validation with initial_data so I am doing like this to save the user automatically from the token provided. The user need to provide everything except his own user. Is it ok or am I doing something not recommended ? @api_view(['POST']) @permission_classes([IsAuthenticated]) def add_mesure(request): serializer = MesureSerializer(data=request.data) serializer.initial_data['user'] = request.user.id if serializer.is_valid(): serializer.save() return Response(serializer.data) -

Django : Reduce number of possible choices based on previous model choice inputs

Forbidden (CSRF cookie not set.) only thrown on a single view when I have disabled CSRF protections on POST?
I am developing a django backend using the djangorestframework and simplejwt authentication. I am using it for a react native mobile app so I am disabling CSRF protections for my views. For some reason, even though every other view works without issue, my token blacklist view throws an error Forbidden (CSRF cookie not set.)
