Django Rest CORS Permissions Default
I am in the process of building a React App to talk to Django as the backend via the Django Rest Framework. I have installed the relevant packages and am trying to configure my default behavour when accessing the views to block access and have the following in my settings.py file REST_FRAMEWORK = { 'DEFAULT_PREMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.SessionAuthentication', ] } My view access the data is: from django.shortcuts import render from django.http import JsonResponse from .models import Articles from .serializers import ArticleSerializer # Create your views here. def articles_list(request): articles = Articles.objects.all() serializer = ArticleSerializer(articles, many=True) return JsonResponse(serializer.data, safe=False) def get_article(request, articlename): article = Articles.objects.get(name=articlename) serializer = ArticleSerializer(article, many=False) return JsonResponse(serializer.data, safe=False) Am I missing something completely simple as I can still access this when when not currently authenticated to the Django backend.

Django: django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: account
I want to use django-helpdesk (which uses account) with django-allauth (which uses allauth.account). Obviously these conflict. I already have a forked version of django-allauth and I don't want to change any code as I am using the forked package in other projects. Is there any way I can change the app label of django-allauth without modifying source code? -
How to have a 'Folder' ForeignKey sorted by folders and subfolders
I have models for scripts and folders, with the scripts inside the folders. When registering a new script (or modifying an existing one) in the Django Admin page, the folders are not represented as folders and subfolders, but rather all at the same time under the form of a list, without anything to distinguish which one is a parent or a child of another one in the list. What I want is to have them clearly ordered, with subfolders underneath their parent (Or atleast display the path from the root folder instead of just the name of the folder to be able to tell where they are if what I want is not possible). I hope I'm clear, but to try explaining differently, have like a ChoiceField with the following choices : FOLDER_CHOICE= [ ('Folder1', ( ('folder1-1', 'Folder1-1'), ('folder1-2', 'Folder1-2'), ) ), ('Folder2', ( ('folder2-1', 'Folder2-1'), ('folder2-2', 'Folder2-2'), ) ) ,... ] The code of the models.py class : import importlib.util import os import shutil import types from django.db import models from django.urls import reverse from django.utils.html import format_html class Folder(models.Model): folder_name = models.CharField(max_length=200, unique=True) parent_folder = models.FilePathField(path=r'media/', allow_files=False, allow_folders=True, recursive=True) def __init__(self, *args, **kwargs): super(Folder, self).__init__(*args, **kwargs) self.initial_folder_name = … -
Delete folder or directory using API (django)
I have written down a Python script to delete or remove a folder from file directory. The code is below: import os import sys import shutil base_dir = os.path.dirname(os.path.realpath(__file__)) path = 'media/user110' try: path = os.path.join(base_dir, path) shutil.rmtree(path) print("Deleted: " + path) except OSError as e: print("Error: %s - %s." % (e.filename, e.strerror)) This worked. But it's not working in API using Django. If I print path it shows '/home/Desktop/my_project/media/user110/ But when I want to do this in API using Django, using same code, and print path I got /media/user110/ and it throw an Exception saying this directory doesn't exist Now I want to delete or remove file directory using API. I want the solution. BTW, I am using Linux, and my project will deploy in Linux server. -

Mocking a method_decorator in django pytest?
I need a bit of guidance on the correct way to mock a method_decorator for a dispatch function. I have a method_decorator that appends log to a log file. I want to mock the method_decorator(log_request) for the dispatch function in my view. Tried to patch it but it doesn't seem to work. What could I be doing wrong ? class DummyView(APIView): serializer_class = DummySerializer @method_decorator(log_request) def dispatch(self, *args, **kwargs): return super(DummyView, self).dispatch(*args, **kwargs) class TestCustomersView: @patch("dummy.api.create_dummy") @patch("dummy.api.log_request") def test_dummy_view(self, mock_log_request,mock_create_dummy): post_data = dict(first_name="Test") mock_log_request.return_value = "Ok" mock_create_dummy.return_value = {"id": "12345", "First_Name": "Test"} req = RequestFactory().post("/api/dummies/", data=post_data) response = DummyView.as_view()(req) -
drf_yasg only renders filterset parameters on list view

how to post data of two models in single view.py using serializer? django rest framework

Create and persist service object in root of django app
I've created a basic django app that has a custom library installed (uses Asyncio). I need to instantiate a factory class from the library and then use it to get some service objects back to use in the app. creds = load_creds('./creds.json') async with TestFactory(creds) as factory: tickets = factory.get_ticket() results = await tickets.find_by_number('IN12345678') print (results.ticket_group) I've only been looking at Django for the last few days. So I'm not sure where is best to place this code. I just need it to persist the service objects I'm generating from the factory class and make them accessible to the rest of the app for as long as the app is running i.e. scaffold once, always accessible. From a c# perspective, I could do this during app startup and pass it down via DI. -

Django REST framework: Serializer to use max_length from model
I have a model class Person(models.Model): name = models.CharField(max_length=254) and related serializer class PersonSerializer(serializers.Serializer): name = serializers.CharField(max_length=254) Is there a way to make CharField automatically detect max_length from the model and use that in validation? Using Person._meta.get_field('name').max_length could be an option but feels a bit cumbersome to be used in every field. Maybe overriding CharField with custom implementation? Or is there other options? -

dj-rest-auth token not deleted in backend after logout
I started using the django dj-rest-auth package with react and i ran across the following issue: When i logout it will clear the key inside the local storage but not inside the Django backend. When i go to the API endpoint page and click the "send post request" button it will do it, but it won't do it when i use my frontend to logout.

Combining custom django crispy forms' FormHelper and HttpResponse with context
I am working on a django project with an app which has lots of related fields like ForeignKey and ManyToManyField. There is a Model that I can call it "OriginModel" for I can access all other models through it. I've tried to render this model with a template and form using context but it seems like not manageable or hard to manage further changes and additions. Because I was hardcoding one OriginModel's all relations in a template. I've changed my method by using inclusive tags for repeating relations but I think it's a bad practice for manageability reason once again for my case. So I've changed my method again. I've tried crispy forms' FormHelper and Layout classes to create OriginModel's form. But I've faced a problem: I couldn't populate related fields with this method. Only OriginModel's direct fields (like "initials" in the code below) could be rendered. And after this failure I coded classes like FormHelper and Layout but my classes have functions to return html string just like my template file, so those are like HTML generators with extra steps I think. Because these classes have been built to return html ultimately, I used HttpResponse in the view of … -
