Django Filter: "Sort By" Feature
I want to sort the products based on boolean field "is_featured", date creation, and price. My goal: This is what i want to achieve. Images shows a website that I am taking ideas from.

React frontend + graphene Django backend SPA deployment
I want to deploy a SPA on only one VM, with debian 10. What I wanted to do is all routes to go to index.html of my static react app, except /admin/* and /graphql/* which should lead to the corresponding django pages. I have tried using Caddy, setting up a reverse proxy for /admin/* and /graphql/* but I end up with a working frontend and a working admin page (but the style of this page is not loaded for some reason). However, the graphql page does not work at all (blank page) and the frontend cannot make request to the backend. Do you know how I should do it? I was wondering if I'd rather go with nginx and uWSGI instead of using Caddy, with which I had to use gunicorn, but then I would need help to configure nginx properly. Or maybe the way I wanted to do it is a dead-end and I should totally change it? Thanks for your help! -
Django new version 3.1, the settings file have some changes
On Django new version 3.1, the settings file have some changes, and I came to ask how I have to proceed to set my static files? The way that I usually did doesn't work more. Last versions: import os BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) Version 3.1: from pathlib import Path BASE_DIR = Path(__file__).resolve(strict=True).parent.parent I usually set my static files like this: STATIC_URL = '/static/' MEDIA_URL = '/media/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static') ] STATIC_ROOT = os.path.join(BASE_DIR, 'static_root') MEDIA_ROOT = os.path.join(BASE_DIR, 'media_root') If I insert the import os will work, but is it the right practice? What is the best practice to set this? Thank you? -

I am using Django RestFramework API in my Node.js App. I am using Javascript fetch API to send some data to backend of my Project which is configured in Django. But the data is not getting posted. It runs fine in PostMan but not using fetch. my API class is as follows: class ProfileList(APIView): def get(self, request): ProfileObjects = Profile.objects.all() serializer = ProfileSerializer(ProfileObjects, many=True) return Response(serializer.data) def post(self, request, **kwargs): print(request.POST) print(self.request.POST) ProfileObjects = Profile.objects.all() serializer = ProfileSerializer(ProfileObjects, many=True) return Response(serializer.data) The fetch call looks like this..: function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } var csrftoken = getCookie('csrftoken'); fetch('http://127.0.0.1:8000/API/', { method: 'post', headers: { 'Accept': 'application/json, text/plain, */*', 'Content-Type': 'application/json', 'Authorization': csrftoken }, body: JSON.stringify({data: "your data"}) }).then(res => res.json()) .then(res => console.log(res)); Well according to the API class view it should print {data: "your data"} but it isn't.
