Error: Request failed with code 403 in axios post api
I am struggling with this problem for a while. I have a new django-vue project, just created it. When I press a button that makes a api request I get the 403 error and recieve "Forbidden (CSRF cookie not set.):" through console. I made some other little newbie projects and I never pass the CSRF token before in a api post. I think that must be another error but I don't know which one The code is the following: views.py from django.shortcuts import render from django.http import HttpRequest, HttpResponse, JsonResponse, HttpResponseRedirect from django.shortcuts import redirect from django.contrib.auth import authenticate, login from django.contrib.auth.decorators import login_required import requests def discord_login(request): print('Hola, cómo estas') return redirect(auth_url_discord) settings.py from pathlib import Path ALLOWED_HOSTS = [] # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework.authtoken', 'corsheaders', 'djoser', 'key', 'discordlogin', ] CORS_ALLOWED_ORIGINS = [ 'http://localhost:8080', ] REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ), } MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ROOT_URLCONF = 'leviathan_django.urls' TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] WSGI_APPLICATION = 'leviathan_django.wsgi.application' DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', … -
How to use regex in django query to get the shortest match?
I have some bunch of entries in a column of a Postgres database that looks like below Abcd/* Abcd/dir1/* Abcd/dir1/dir2/* Abcd/dir1/dir2/dir3/* I am using django ORM to access this information like below given_path = "/some/path" access_obj = Access.objects.get(dir_id=given_path) #dir_id is the column name Now given a path, I need to find the earliest match (any path after * is allowed, hence don't search further) and give the result back. What I mean is say a path is given Abcd/dir1/dir2, since my first entry itself is Abcd/* so I don't need to look any further and return the first row object itself. Currently I try to fetch using __icontains check like below access_obj = Access.objects.get(dir_id__icontains=given_path) But it would return all the matches and then I am unable to figure out how to target the first match (in this case) and query the object. I am aware django supports regex on queries but I am not sure what to apply here. Any help will be appreciated. -
How do delete an object using axios and Django?
I've got a react Frontend, and a Django backend. I am basically trying send some data to the backend in order to filter out the desired object to delete it. However, I am only able to delete an object when both the django method and the axios method are PUT, not DELETE.

Is it safe to add EC2 public IP to ALLOWED_HOSTS in Django + Elastic Beanstalk?
I have deployed a Django app as a single instance Elastic Beanstalk environment without Elastic Load Balancer. The setup is Nginx + Gunicorn + Django. SSL is enabled for Nginx server. I have added the host assigned by elastic beanstalk (....elasticbeanstalk.com) to ALLOWED_HOSTS in the settings file, and the app is accessible. But some operations are failing and there are a lot of Invalid HTTP_HOST_HEADER errors in the log file. The header in majority of these errors are the Public IP of the EC2 instance.

Can I (safely) override Django settings in a server side wsgi.py?
I want to deploy two Django web-apps (individual domains) that share the same source code/repository and, hence, the same settings file. (Hosted on pythonanywhere by the way). The only difference between the two is that they should access different data bases (which I would usually define in settings.py or .env). As I see it, the only file that is unique to each web-app is their individual ...wsgi.py file (the one on the server not the one in the Django project folder). Thus, my idea is to use that file to specify each app's data base settings. Is it possible to (safely) override settings in a wsgi file? How would I do it? The current wsgi.py file looks like this: # +++++++++++ DJANGO +++++++++++ # To use your own django app use code like this: import os import sys # ## assuming your django settings file is at '/home/.../mysite/mysite/settings.py' ## and your manage.py is is at '/home/.../mysite/manage.py' path = '/home/.../...' if path not in sys.path: sys.path.append(path) # os.environ['DJANGO_SETTINGS_MODULE'] = 'core.settings' # ## then: from django.core.wsgi import get_wsgi_application application = get_wsgi_application() Many thanks for your help! -

Why does the Django FileInput widget never render a value? Is it a security risk?
In the source code (link) for Django Widgets it's clear that FileInput does not render a value: # django.forms.fields class FileInput(Input): input_type = 'file' needs_multipart_form = True template_name = 'django/forms/widgets/file.html' def format_value(self, value): """File input never renders a value.""" return This is different to other fields such as CharField which returns an initial string: # django.forms.fields def format_value(self, value): """ Return a value as it should appear when rendered in a template. """ if value == '' or value is None: return None if self.is_localized: return formats.localize_input(value) return str(value) Why is this? It means that if you set a default value in a FileField it is not rendered, which can be confusing for the user. Is it a security concern? The value is stil rendered if the user has previously uploaded a file (I assume via the ModelField not the FormField?), so I don't see the difference? -

Map Flask API and Django app to same database but different tables
I have a database model which is written in Django ORM and the same database is used by Flask using SQLAlchemy for another microservice (where I need only 2/3 new and 1 exiting table) to store and query some data. So when from my Flask API, I run this command- $ flask db migrate $ flask db upgrade I can see that from migrations/versions, it is trying to delete existing tables of my Django app which I don't want to do. So my question is how to run/use Flask SQLAlchemy ORM without touching existing tables of Django app? Also From my Flask app, I want to refer to some of the existing tables of the Django app but am not sure how to do those without creating models on the Flask app because those models are already created by Django APP. N.B For a particular reason I don't want to separate the Flask API to another database
