Add Django super user token in http request
I use Django (as backend and frontend) for a website. I want to create http request with the condition (of use) to be Django super user. But I don't know how to add in the headers the token (or the proof that the user that uses the request is a super user). I tried this with the csrf token : First I use the {% csrf_token %} in the template. <form action="#" id="admin-add-event" method="POST"> {% csrf_token %} ... <button type="submit" id="admin-submit">Add event</button> </form> const url = `${window.BASE_URL}events/`; const form = document.getElementById('admin-add-event'); const data = { ... } let xhr = new XMLHttpRequest(); xhr.open('POST', url , true); xhr.setRequestHeader('X-CSRFToken', form.elements.csrfmiddlewaretoken.value); xhr.setRequestHeader("Content-Type", "application/json"); xhr.onload = function () { ... } xhr.send(JSON.stringify(data)); And in the Django view of the endpoint : @api_view(['GET', 'POST']) def all_events(request): if request.method == 'POST': if not request.user.is_superuser: return Response(status=status.HTTP_401_UNAUTHORIZED) # etc ... But the check of super user fails always I precise that I don't want to implemente a user system. I want to use the system of super user of Django. Thanks in advance ! -
How to use Django ImageField to upload to Google Cloud Storage instead of local
I want to use Django's ImageField on a model so people can upload a logo. I found the ImageField however reading from the docs it says Django stores files locally, using the MEDIAROOT***andMEDIAURL** settings.py I'm wondering how I can change the *upload_to= behavior to upload to a gcp bucket instead? If it's possible when I call .save what is saved to the database, the gcp bucket url? From reading the docs it doesn't say one way or the other if this is possible or if all images should be stored locally where the service is being ran. I have thought of saving the binary images directly to the db but that seems inefficient. -

Django reverse() behind proxy
My Django REST API is deployed behind an API Gateway (Kong). I want to reserve() some urls in my APIViews. I would like to ask for help to get the right url format. Based on basepath of the API gateway. Communication flow: Client (requesting basepath) <-> Kong (forwarding to upstream) <-> Apache (Reverse Proxy) <-> Django Kong defines a basepath and an upstream to forward client request to Django. Kong includes X_FORWARDED_HOST and X_FORWARDED_PATH in the HTTP header. X_FORWARDED_PATH contains the basepath of the gateway. X_FORWARDED_HOST contains the gateway-url. Gateway basepath is: /gateway-basepath Upstream path is: mydomain.com/py/api/v1 Basically, without gateway, Django reverse() creates following url for users endpoint: mydomain.com/py/api/v1/users/ With the API gateway, the Django creates follow path: apigatewayurl.com/gateway-basepath/py/api/v1/users/ Django is considering X_FORWARDED_HOST, but not X_FORWARDED_PATH I need following result: apigatewayurl.com/gateway-basepath/users Otherwise the Django url resolving is not usable within the api gateway. I would appreciate any help. urls.py from rest_framework.views import APIView from rest_framework import routers from . import views class APIRootView(APIView): def get(self, request, format=None): return Response({ 'users': reverse('user-list', request=request, format=format), }) router = routers.DefaultRouter() router.register(r'users', views.UserViewSet) urlpatterns = [ path('api/v1/', APIRootView.as_view(), name="api_root"), ] urlpatterns += router.urls views.py from rest_framework import viewsets from django.contrib.auth import models as django_models … -
Django 404 email notification

Getting a problem after deploy a Django app on Render
I developed an app in Django using PostgreSQL as DataBase, on a local environment it works without problems, but when it was deployed on Render.com it the app throws me this error.

How can I modify attributes of objects in a Django queryset for data presentation without modifying the original object?
I want to present a list of objects for which I want to filter/modify one attribute during the presentation of the data. Something close to an annotation, but I did not manage to do it with annotations. These are the models class Airline (models.Model): name = models.CharField() destinations = models.ManyToManyField("city") customers = models.ManyToManyField("user") class City (models.Model): name = models.CharField() country = models.CharField() class User (models.Model): name = models.CharField() preferredDestinations = models.ManyToManyField("city") I want, for a given user, present a list of the Airlines the user is customer, and for each Airline present the list of destinations for the Airline. But instead of presenting all the airline destinations I only want to present the destinations preferred by the user. e,g, Airline1.destinations=["New York", "London", "Paris", "Madrid] Airline2.destinations=["Madrid", "Barcelona", "Rome", "Berlin", "London"] User1.preferredDestinations=["Madrid", "Barcelona", "Paris"] With user1 being a customer of Airline1 and Airline 2, I want the page to present a table showing to which of the user preferred destination every airline flies to. I.e. I do not want to see all the destinations the airline flies to, only the ones the user is interested: E.g. Welcome User1! These are your airlines that fly to your preferred destinations Airline | Destination | … -
DJANGO: replace a combobox created successfully in a list of views.py, with one created with classes in forms.py?
I'm new to Django. I saw that there are 2 different ways to create comboboxes and forms. I would like to replace my current mode, already successfully created, with another mode. WAY 1 (works well, correctly): I have a combobox that works fine, created by putting the items in a list in views.py, for example: color_choices = ("Red","Blue","Black", "Orange"). I am currently using this mode. WAY 2: Way 1 works fine correctly for me, but only now I've seen that it's possible to create comboboxes also by creating a forms.py file, importing from django import forms, and then writing the items in the classes. The combobox uses a static list QUESTION: How can I modify my code (which uses Way 1) and replace it with forms.py with Way 2 classes? I would like to use the classes and the forms.py file, and I would not like to use the items in the views.py file (it works correctly fine with Way 1). Can you show me how I can use Way 2 correctly? Thank you all! Which of the two ways is more correct and better in terms of loading speed? Thank you all! P.S: comboboxes are database independent. they don't … -

use django-filters on a queryset in the backend
