Not being able to send emails on a django backend from a React frontend
On a form submission from my React frontend, my django backend sends emails to multiple user. I am not using any sort of backend queue for the job scheduling (for now), so the request should take little time to complete. Its important to note that I am using axios interceptors for refreshing tokens on a 401 response. Now, the thing is, everytime someone submits the form and there is more than 1 user to send an email to, I get a 401 response to my axios interceptor and it fails. But when there is only 1 user they send an email to, it works fine. I understand this might be hard to visualize without code context, but would really appreciate if someone has any idea as to why this might happen? -
Query of coordinate data in Folium (ClickForMarker)
everyone, I am currently creating a small project with python / django. I would like to develop a tool in which the user can mark a point on a map - and then send it off using the "Remember address" button. This data should then be stored in the database. I use Folium / Leaflet for this. With the function "ClickForMarker" I can already mark points on the map. Now to my question :) Currently, a new marker is placed with each click - however, I would like that if a user clicks several times, the marker is always updated. How can I read out the data (coordinates). Or do I have a "Send data" button below the map - can I process the post request with the data? I don't think I have to mention that I'm still a beginner - with Javascript, for example, I only know very little. I'm happy about any help :) -
Django generic views with form_class and model attributes
In a note about generic views in Django's docs, it says that even if form_class is set, the model attribute should be set too. But I've seen many examples (some on Django docs itself) that only the form_class was specified. Also, inside the ModelFormMixin class (generic views inherit from it) you can find this: if self.form_class: return self.form_class else: if self.model is not None: # If a model has been explicitly provided, use it model = self.model It's in the 'else' that it would look for the model. So for views that inherit from generic views like FormView or CreateView, is it necessary that I set the model attribute if I've set the form_class? If not, then what is that note talking about? -
Django admin LogEntry error with remote authentication
I'm using Central Authentication System (CAS) with my Django services. User is authenticated by remote server and not Django auth itself. I have also changed Authentication Backend as follows : class CASBackend(BaseBackend): def authenticate(self, request, username=None, password=None): payload = get_cas_payload(request) user, _ = User.objects.get_or_create(username=payload['username']) def get_user(self, user_id): try: return User.objects.get(pk=user_id) except User.DoesNotExist: return None When creating a new object in admin, I got the following error : django.db.utils.IntegrityError: null value in column "user_id" violates not-null constraint Which is related to LogEntry. Is there anything I have missed? -
How to Serialize ManyToManyfield in django rest framework
Sorry to ask a repetitive question which is already have been asked a lot of times. I have seen alot of answers on this topic. But I can't reproduce the solution of my problem. Basically I want to serialize a field name partner which is in quote model Quote(models.Model): #... partner = models.ManyToManyField( Partner, blank=True, related_name='quote_partners') and this is the Partner models in the accounts app class Partner(models.Model): id = models.UUIDField(primary_key=True, unique=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=100, blank=True, null=True) group = models.OneToOneField( Group, on_delete=models.DO_NOTHING, blank=True, null=True) def __str__(self): return self.name And this is how the serializer looks class QuoteListSerializer(serializers.Serializer): """ For the List views """ #... id = serializers.UUIDField(read_only=True) partner = serializers.CharField(read_only=True) I'm getting all other fields properly but not the partner field. This is the end results looks : { "id": "cbf64980-1637-4d0d-ad1f-4eb6421df5a1", "partner": "accounts.Partner.None", }, However I can see the partners field is filled for this specific entry in the admin page but not showing in the serialized data. In the Partner Model In the Quote [][2 Anybody knows why this is happening and how to fix this issue. -
DJANGO IF STATEMENT FOR CONTEXT USAGE IN TEMPLATE
What i am trying to achieve: i am getting data from an API, i want to display that data in my template only if the conditions are met. What i tried #1: i added a boolean in my model that is linked to the API called "accessconfirmed" and then in my views i added a if statement saying if access is confirmed then display this context and if not then display this other context. i dont get an error but my data from the API is no longer displaying, i get nothing. here is the code in the views.py VIEWS: def projectdetailscoins(request, pk): coin = Coin.objects.get(id=pk) notifications = Notification.objects.all() accessconfirmed = Coin.is_api_access api_coin_number_variable = coin.api_coin_number url = 'XXX' parameters = { 'slug': coin.api_slug, 'convert': 'USD', } headers = { 'Accepts': 'application/json', 'X-CMC_PRO_API_KEY': 'XXX' } session = Session() session.headers.update(headers) response = session.get(url, params=parameters) api_price = response.json() if accessconfirmed == True: context = {'coin':coin, 'notifications':notifications, 'gimmeprice':api_price['data'][api_coin_number_variable]['quote']['USD']['price'], 'gimme24h':api_price['data'][api_coin_number_variable]['quote']['USD']['percent_change_24h'], 'accessconfirmed':accessconfirmed, } else: context = {'coin':coin, 'notifications':notifications,} return render(request, 'blog/project_details_coin.html', context) What i tried #2: i also tried changing the if statement from if accessconfirmed == True: to if accessconfirmed: the data displays correctly on my template if i do that, but when i go … -

Django URLs not working properly in template
I am making social network website where user can post and like the post. On one of my templates, image of heart (which represents if post is liked or not) is not loading because of incorrect path: this is the incorrect one: other_profile/static/network/nolike.png. It should be: static/network/nolike.png. other_profile is the name and path of my template. Same happens in case of other API fetch calls on my website. URL should not begin with other_profile. And this happens only on other_profile HTML page. The code: urls.py from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path("profile", views.profile, name="profile"), path("login", views.login_view, name="login"), path("logout", views.logout_view, name="logout"), path("register", views.register, name="register"), path("Post/<str:post_id>", views.likes, name="likes"), path("follows/<str:user_id>", views.follows, name="follows"), path("following", views.following, name="following"), path("other_profile/<str:user_id>", views.other_profile, name="other_profile") ] views.py snippet import json from urllib.request import Request from django.contrib.auth import authenticate, login, logout from django.db import IntegrityError from django.http import HttpResponse, HttpResponseRedirect from django.shortcuts import redirect, render from django.urls import reverse from .forms import NewPostForm, likeForm, followForm from .models import User, Post, Likes, Follows from django.contrib.auth.decorators import login_required from django.http import JsonResponse from django.core.exceptions import ObjectDoesNotExist from datetime import datetime def other_profile(request, user_id): followform = followForm(request.POST or None) if request.method == "POST": try: Follows.objects.filter(following__in=[user_id]).get(following=request.user).delete() except … -
Django Rest Framework AuthToken being created without a key
I have a data migration indended to create a couple accounts in django, along with a token for authentication. class Migration(migrations.Migration): initial = True dependencies = [ migrations.swappable_dependency(settings.AUTH_USER_MODEL), ('api', '0001_initial'), ('authtoken', '0001_initial'), ] operations = [ migrations.RunPython(api.models.user.create_service_accounts, api.models.user.delete_service_accounts), ] And the create method: def create_service_accounts(apps, schema_editor): User = apps.get_model('api', 'User') Token = apps.get_model('authtoken', 'Token') db_alias = schema_editor.connection.alias new_user = User.objects.using(db_alias).create(username='sa', is_superuser=True, is_staff=True) token = Token.objects.using(db_alias).create(user=new_user) After this migration is run, a token is created. But the token does not have a key. Therefore it is useless. Why is it getting created without a key? If I manually create a token it works fine, but through this migration it provides a blank key. -

os.environ.setdefault('DJANGO_SETTINGS_MODULE') doesn't work
I'm trying to run a standalone script that uses the Django models for accessing the database. The script is very simple, see below: import sys from manager.models import Playlist from manager.utils import clean_up_playlist, add_record_to_playlist def main(playlist_id, username): playlist = Playlist.objects.get(playlists=playlist_id) # the script does other stuff if __name__ == "__main__": playlist_id = sys.argv[1] username = sys.argv[2] import os os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'SpotifyPlaylistManager.settings') import django django.setup() main(playlist_id, username) The script is in the top folder of the Django folder SpotifyPlaylistManager/ |-SpotifyPlaylistManager/ |-settings.py |-venv |-manage.py |-my_script.py For some reason, if I try to run it with the command below I got the error raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured.

Why does my functions based API POST respond with .accepted_renderer not set on Response
I have a function-based view: api_view(['POST']) def scoring_logicapp_kickoff(request, prediction_id): if request.method == 'POST': url = "https://FAKEURL.net" payload = json.dumps({ "prediction_id": prediction_id }) headers = { 'Content-Type': 'application/json' } requests.request("POST", url, headers=headers, data=payload) return Response(status=status.HTTP_202_ACCEPTED) return Response(status=status.HTTP_400_BAD_REQUEST) FAKEURL is actually a URL that sets off an Azure Data Factory logic app. I originally was getting a 403 error "Forbidden (CSRF cookie not set.)". I then wrapped the URL endpoint to quickly circumvent the issue: path('logicapp-trigger/<int:prediction_id>/', csrf_exempt(views.scoring_logicapp_kickoff)) Now I'm getting the error: "AssertionError: .accepted_renderer not set on Response" Any idea how to fix the original csrf error or the response error? I'm a bit stuck. -

How do I upload all the files in a django app to a git brand new repository?
I'm using Django in PyCharm for a simple project. I have a github account, git installed on my environment and github desktop, but I can't figure out how to upload all the files in my entire app project to a git repository all at once, to then view it on github. I haven't been using Git at all throughout the project and it has cost me when making irreversible mistakes. So what's the easiest way to use Git/github with Pycharm. i got the extension for it but I find the interface a bit confusing. -

Why is collectstatic only detecting admin static files?
I'm using S3 to store my static files, but I'm having an issue where only the admin static files are uploading to the bucket. I expected to see the css and other folders from inside static upload to the bucket, but instead, this is all I got: static/ - admin/ - flags/ What can I do to get my app's static folder to upload also?

how to make a post request and get the radio button values in django
I'm doing a website in django but this is the first time i use this framework so i'm not so used to it. I need to save some information on a DB, and i need to take these information from some radio buttons. I tryied so many ways to get the data but nothing worked. So i'd like to ask how to get these data in models.py from a template.html. This is the code in views.py: def question1(request): form = CHOICES(request.POST) if request.method == 'POST': form = CHOICES(request.POST) if form.is_valid(): selected = form.cleaned_data.get("NUMS") return render(request, 'q1.html', {'form': form}) This is the template question1.html: <form class="form-inline" method='POST' action="" enctype='multipart/form-data'>{% csrf_token %} {% csrf_token %} {{form.path}} </form> Then there is the form in forms.py: NUMS = [ ('one', 'one'), ('two', 'two'), ('three', 'three'), ('four', 'four'), ('five', 'fives'), ] class CHOICES(forms.Form): NUMS = forms.ChoiceField(choices=NUMS, widget=forms.RadioSelect) I checked and I think that the problem could be the request.method that is GET insted of POST. So how can I make a POST request? Thank you
