Inspect db Issue
I am working on a Django project but when I perform the database inspection in the app and try to run the project it fails with the following error. OSError: [WinError 123] The filename, directory name or volume tag syntax is not correct: '' What is the best way to handle this? This is my database config DATABASES = { 'default': { 'ENGINE': 'mssql', 'NAME': 'pos_service', 'USER': 'demoLogin', 'PASSWORD': 'demoLogin', 'HOST': 'LAPTOP-EQ88J4ES\SQLLOCAL', 'PORT': '1433', 'OPTIONS': { 'driver' : 'ODBC Driver 13 for SQL Server' } } } How is the correct way to inspect a database in Django and how would be the best way to import each of the classes? -
Is the level of protection in Next js too high? [closed]
Is the level of protection in Next js too high if they are used as a ForntEnd in terms of uploading and receiving files and opening sessions with django rest APIs ?

Django Rest Framework - adding permissions for views based on groups?
TLDR: How do you permit specific Groups access to views using Django Rest Framework? I'm in the process of building a web service with the Django Rest Framework. Only a (proper) subset of the views are intended to be available to customers. So far, I've: set the default permission to rest_framework.permissions.IsAdminUser created a permission called is_customer (using the Django admin website) created a Group called customers and added all relevant users to this group (using the admin website) added the is_customer permission to customers (again using the admin website) All of my views are function-based. To provide the appropriate permission to the customers group, I've tried from rest_framework.decorators import api_view from django.contrib.auth.decorators import permission_required @api_view(["POST"]) @permission_required(["is_customer"]) def my_func(request): # calculations return Response(...) and from rest_framework.decorators permission_classes, api_view @api_view(["POST"]) @permission_classes(["is_customer"]) def my_func(request): # calculations return Response(...) and neither seems to be working. What is the proper way to go about this? Thanks in advance for any advice! -

Is there "non-lazy mode" or "strict mode" for "querysets" in Django?
When I use select_for_update() and update() of a queryset together as shown below: # "store/views.py" from django.db import transaction from .models import Person from django.http import HttpResponse @transaction.atomic def test(request): # Here # Here print(Person.objects.select_for_update().filter(id=1).update(name="Tom")) return HttpResponse("Test") Only UPDATE query is run without SELECT FOR UPDATE query as shown below. *I use PostgreSQL and these logs below are the queries of PostgreSQL and you can check on PostgreSQL, how to log queries with transaction queries such as "BEGIN" and "COMMIT": But, when I use select_for_update() and update() of a queryset separately then put print(qs) between them as shown below: # "store/views.py" from django.db import transaction from .models import Person from django.http import HttpResponse @transaction.atomic def test(request): qs = Person.objects.select_for_update().filter(id=1) print(qs) # Here qs.update(name="Tom") return HttpResponse("Test") SELECT FOR UPDATE and UPDATE queries are run as shown below: Actually, this example above occurs because QuerySets are lazy according to the Django documentation below: QuerySets are lazy – the act of creating a QuerySet doesn’t involve any database activity. You can stack filters together all day long, and Django won’t actually run the query until the QuerySet is evaluated. But, this is not simple for me. I just want normal database behavior. Now, … -

Post request to Djoser user registration route 'appName/v1/users/' throws 401 error
I'm new to Django and trying to build basic user authentication with REST API and a Vue.js frontend. To send the request, I am using axios, which is configured first in a seperate composable axios.js: import axios from 'axios' axios.defaults.withCredentials = true axios.defaults.baseURL = 'http://localhost:8000' and used inside a register.vue component: const submitRegistration = () => { axios.post('api/v1/users/', {username: 'userName', password: 'userPassword'}) .then(res => { console.log(res) }) } To make it simple, I'm sending a data-object with predefined strings, as you can see above. The request gets sent to one of the djoser routes in projectName/urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('api/v1/', include('djoser.urls')), path('api/v1/', include('djoser.urls.authtoken')), ] This however, throws a 401 Unauthorized Error: code: "ERR_BAD_REQUEST" config: {transitional: {…}, adapter: Array(2), transformRequest: Array(1), transformResponse: Array(1), timeout: 0, …} message: "Request failed with status code 401" name: "AxiosError" request: XMLHttpRequest {onreadystatechange: null, readyState: 4, timeout: 0, withCredentials: true, upload: XMLHttpRequestUpload, …} response: {data: {…}, status: 401, statusText: 'Unauthorized', headers: AxiosHeaders, config: {…}, …} stack: "AxiosError: Request failed with status code 401\n at settle (http://localhost:3000/node_modules/.vite/deps/axios.js?v=a45c5ec0:1120:12)\n at XMLHttpRequest.onloadend (http://localhost:3000/node_modules/.vite/deps/axios.js?v=a45c5ec0:1331:7)" I've configured settings.py like so: INSTALLED_APPS = [ ..., 'corsheaders', 'rest_framework', 'rest_framework.authtoken', 'djoser' ] MIDDLEWARE = … -
