Cannot update model because "id already exists"
I am new to Django and I am trying to use update_or_create in the serializer.create(). However, when I send a request with an existing id for customer, gift or subscription, it shows "id already exists" and does not proceed. What am I doing wrong here?

Django Model Import Error When trying to Import in Another App's Model
I'm working on a Django based project right now. I 'm getting an error something called AppRegistryNotReady when I'm trying to import a model into another app's model with django get_model() method.. Now the interesting this is, I can import the models from another app in the view files with the same get_model() method. In views file: from django.apps import apps Course = apps.get_model('course', 'Course') Order = apps.get_model('course', 'Order') *Now everything is working parfectly.

Django assign user to group during registration based on choice in another field
I would like to automatically assign users to a group based on their choice in another field in the user registration field. I am new to Django and I am not sure of the best way to achieve this. I want to assign the group based on the choice of the "business_location_county" field in the model. In simple terms the group should be the group id where the group "forum_id" equals the id of the business_location_county choice. The group "forum_id" is a custom column added to the Group model. The models.py: from django.contrib.auth.models import AbstractUser from django.db import models from machina.core.db.models import get_model from django.db.models import Q from django.contrib.auth.models import Group Forum = get_model("forum", "Forum") class CustomUser(AbstractUser): age = models.PositiveIntegerField(null=True, blank=True) business_location_state = models.ForeignKey(Forum, null=True, on_delete=models.SET_NULL, limit_choices_to={"lft":1}) business_location_county = models.ForeignKey(Forum, null=True, on_delete=models.SET_NULL, related_name='county', limit_choices_to=(~Q(lft__in = (1,2)))) Group.add_to_class('forum_id', models.PositiveIntegerField(null=True, blank=True)) views.py: from django.urls import reverse_lazy from django.views.generic import CreateView from .forms import CustomUserCreationForm from .models import CustomUser from django.shortcuts import render from machina.core.db.models import get_model from django.db.models import Q Forum = get_model("forum", "Forum") class SignUpView(CreateView): form_class = CustomUserCreationForm success_url = reverse_lazy('login') template_name = 'registration/signup.html' def load_counties(request): parent_id = request.GET.get('business_location_state') counties = Forum.objects.filter(parent_id=parent_id).order_by('name') return render(request, 'hr/county_dropdown_list_options.html', {'counties': counties}) forms.py: from django import … -

Github Auth using Django + React
The problem: Hi, guys! I've been trying to implement Github auth with Django + SPA (React in this case). Something as basic as it can be. But still i'm not able to complete the full workflow. I tried 3 or 4 djangopackages, among them: drf-social-oauth2, social-app-django, python-social-auth. But i couldn't make them work! Maybe I'm dumb, I don't know! The thing is that I could kinda complete the process of getting an access_token from Github. Im using: Django==3.2.4 django-cors-headers==3.7.0 djangorestframework==3.12.4 djangorestframework-simplejwt==4.4.0 PyJWT==1.7.1 What I've tried: This is the workflow from Github docs: here. Basically we need to make a GET request with our CLIENT_ID (you get this from Github by "creating an app") to this endpoint github.com/login/oauth/authorize. The user is gonna get asked if he authorize the app to access their personal information. The user accepts and Github fires a callback function with a CODE as url a param: import asyncio from .github import Github from rest_framework.generics import GenericAPIView from rest_framework.response import Response class CallbackAPIView(GenericAPIView): """ This endpoint receives the CODE and exchange it to a token """ def get(self, request): code = request.query_params.get('code', None) data = asyncio.run(Github.request_access_token(code)) access_token = data.get('access_token') user_email = asyncio.run(Github.get_user_email(access_token)) user = Github.register_or_authenticate( user_email=user_email, access_token=access_token) return … -
migration not working with django and docker?
I have a project where I have developed a Django application which I am trying to containerize and host on my raspberry pi. During development on my local environment the container is working fine (builds and run without any errors). However when I try to run it on my server the migrations just wont work. For some strange reason it is not including my custom user model during migrations. The file structure follows a basic pattern with one folder for the app, and another containing the webserver (nginx). The Django-compiler creates three images (postgres, django, nginx). The main logic related to the Containers could be found in the main Dockerfile. To run the migrations and start the django application Ive included a bash script that migrates all models. However, during the build I get the following error: app_1 | False app_1 | Operations to perform: app_1 | Apply all migrations: admin, auth, contenttypes, sessions, token_blacklist app_1 | Running migrations: db_1 | 2021-06-14 00:36:00.879 UTC [35] ERROR: relation "users_newuser" does not exist db_1 | 2021-06-14 00:36:00.879 UTC [35] STATEMENT: ALTER TABLE "django_admin_log" ADD CONSTRAINT "django_admin_log_user_id_c564eba6_fk_users_newuser_id" FOREIGN KEY ("user_id") REFERENCES "users_newuser" ("id") DEFERRABLE INITIALLY DEFERRED app_1 | Applying admin.0001_initial...Traceback (most recent call … -
Django AttributeError when attempting to save objects to database through model.py
I am working on a web-app that searches the IGDB database for games of a user chosen title, then displays them on screen.

Uploading an image to backend works with Postman but not in my React app
My application is using django rest framework for the backend and react on the frontend. I have a model Place which has several fields, one of which is a photo. I have a front end form that connects to the api endpoint to create a new Place model. Whenever I submit the form through my react form (with the file included), the server responds with a 200 but does not actually save anything to the db. Whenever I submit the form without the file through my react app, it saves the other data successfully. The weird thing is, I can get it to work without a problem using Postman, so my guess is the problem lies within the react component / HTML form. Here is the react component with form: import React, {useState, useContext, useRef} from "react"; import AuthContext from '../store/auth-context'; function NewPlaceForm(props) { const authCtx = useContext(AuthContext); const nameInputRef = useRef(); const latInputRef = useRef(); const longInputRef = useRef(); const completedInputRef = useRef(); const dateCompletedInputRef = useRef(); const photoInputRef = useRef(); const notesInputRef = useRef(); const userId = localStorage.getItem('userId'); const submitHandler = (event) => { event.preventDefault(); const enteredName = nameInputRef.current.value; const enteredLat = latInputRef.current.value; const enteredLong = longInputRef.current.value; const … -
Django Rest Framework "Page Not Found" Error when using drf-nested-routers
We have an API that allows users to save their inventory of player profiles. The API endpoint for that is: /api//api/inventory-live-collection/ /api/inventory-live-collection/20 # gets a single listing from InventoryLiveCollection However, one of the fields inside of this response is very large, so we would like to be able to paginate it and make a request such as: /api/inventory-live-collection/20/needed-inventory/ According to the docs, the drf-nested-routers package is the way to handle this. The docs also made it look extremely simple to use, but I must be missing something, as I get a "Page Not Found" error. Here is the urls.py : router = routers.DefaultRouter() router.register(r'inventory-live-collection', views.InventoryLiveCollectionView) inventory_live_collection_router = routers.NestedSimpleRouter( router, r'inventory-live-collection', lookup='inventory_live_collection' ) inventory_live_collection_router.register( r'needed-inventory', views.NeededInventoryView, basename='needed-inventory' ) urlpatterns = [ path('admin/', admin.site.urls), path('api/', include(router.urls)), path('api/inventory-live-collection/', include(inventory_live_collection_router.urls)), ] views.py class NeededInventoryView(viewsets.ModelViewSet): def get_queryset(self): return PlayerProfile.objects.filter(inventory_live_collection=self.kwargs['inventory_live_collection_pk']) I don't think the model is the issue, but here is the model.py. class PlayerProfile(models.Model): card_id = models.CharField(max_length=120, unique=True, primary_key=True) name = models.CharField(max_length=120, null=True) class InventoryLiveCollection(models.Model): needed_inventory = models.ManyToManyField(PlayerProfile, related_name="needed_inventory") date = models.DateTimeField(null=True, blank=True) Where did I go wrong?

Why does my pre-signed URL for my s3 bucket look different when deployed?
My python (Django) application stores confidential documents and has a private bucket in AWS S3. When you make a request for the resource, it uses boto3 to generate a pre-signed URL to be able to download the document. The code to do so is as follows: @staticmethod def create_presigned_url(key_name, bucket_name=settings.AWS_PDF_STORAGE_BUCKET_NAME, expiration=60): """ Generate a pre-signed URL to share a PDF. :param key_name: string. :param bucket_name: string. :param expiration: Time in seconds for the pre-signed url to remain valid. :return: Pre-signed URL as a string. If error, returns None. """ s3_client = boto3.client('s3') try: response = s3_client.generate_presigned_url( 'get_object', Params={'Bucket': bucket_name, 'Key': f"pdf/{key_name}"}, ExpiresIn=expiration ) except ClientError: return None return response When I run my application locally, it works great. It generates a link I can use to download the document and it expires after 60 seconds. Such URL looks like this: https://BUCKETNAME.s3.amazonaws.com/pdf/testuser1/dummy.pdf?AWSAccessKeyId=ACCESSKEY&Signature=SIGNATURE&Expires=EXPIRATION" I then deploy my application to AWS Elastic Beanstalk. All the same environment variables with AWS secrets are configured. But when I run the same request, I get a much longer URL that looks like this: https://fiber-staging-pdfs.s3.amazonaws.com/pdf/liza/dummy.pdf?AWSAccessKeyId=ACCESSKEY&Signature=SIGNATURE&x-amz-security-token=TOKEN&Expires=EXPIRATION Somehow, the same code when run against this environment is adding a x-amz-security-token parameter?

How to render Custom Django Widget as Buttons for ChoiceField?
I have a Django reviewing and photo sharing application. When a user submits a new Review instance, they can indicate the 'Method of Consumption' using Select widget, which by default will show choices as a dropdown. This is a very bland look. I want to use a custom Widget which will render the choices as buttons. This is far more visually appealing. How do I render the widget such that for each choice, there is a button with value equal to the choice (Flower, Extract, Edible)?

How to add AJAX Mixin to CreateView
I have been adding AJAX functionality by creating separate FBVs which specifically handle AJAX, but I would like to add AJAX functionality directly to a CreateView. I see in the documentation where there is a JSONResponseMixin but I do not want a JSON response.

Invalid block tag on line 9: 'static', expected 'endblock'. Did you forget to register or load this tag?

However, whenever I save this relation, the new object is not being added to the database but no errors are being created. In case anyone has an idea why this is happening, it would be awesome. So here is my code: models.py class Profile(models.Model): id = models.CharField(max_length=50, primary_key= True) user = models.OneToOneField(User, on_delete=models.CASCADE) sdg = models.ManyToManyField(SDG, through="SDG_User") background_picture = models.ImageField(upload_to=profile_pic_directory_path,default="Null") profile_picture = models.ImageField(upload_to=profile_pic_directory_path,default="Null") class SDG_User(models.Model): sdg = models.ForeignKey(SDG, on_delete=models.CASCADE) user_id = models.ForeignKey(Profile, on_delete=models.CASCADE) class SDG(models.Model): title = models.CharField(max_length=50, unique=True) contenu = models.TextField(default="NA") image = models.ImageField(upload_to='sdgs/') def __str__(self): return '{} - {}'.format(self.title, self.contenu) forms.py class SDGForm(forms.ModelForm): sdg = forms.CheckboxSelectMultiple() class Meta: model = Profile fields = ('sdg',) views.py def edit_profile_sdgs(request): if request.method == 'POST': sdg_form = SDGForm(request.POST,instance=request.user) if sdg_form.is_valid(): sdg = sdg_form.save(commit=False) sdg.user = request.user sdg.save() sdg_form.save_m2m() messages.success(request, 'if') return redirect(reverse(("accounts:user_profile"),args=[request.user.username])) else: sdg_form = SDGForm(instance=request.user) return render(request, 'dist/inside/profile/edit/edit_sdg.html', { 'sdg_form': sdg_form, }) -
Heroku, problem running django app due to bash: ps:scale: command not found

How to debug a Django view through Heroku?
I found a bug in my web application and I am trying to debug one of my views through the LOGGER to visualize the results that my code is generating. This is the code implementation: import logging .... @login_required def retrieve_results(request): template_name = 'task/formRetrieval.html' status = 'In Progress' status_task = 'Active' logging.basicConfig(filename='std.log', filemode='w' format='%(asctime)s,%(msecs)d %(name) %(levelname)s %(message)s', level=logging.DEBUG) logger = logging.getLogger() qs_current = Task.objects.filter(accounts=request.user.id).values('id').values_list('id') logger.debug(str(qs_current)) ... The output is an empty std.log file, no result was logged. I am wondering if there's a permission problem that prevents my code from writing files into the heroku container. I even went a step further and I decided to create a txt file and I tried to log the results there but I only found an empty file. I have some questions: If Heroku is preventing me from creating a new file then is there a solution to indicate that logging files should be allowed? How can I indicate to Django to log a new file? Any help or suggestion is really appreciated :) Thank you
