Is Django-REST-framework stateless?
According to REST API principles: Stateless – Each request from client to server must contain all of the information necessary to understand the request, and cannot take advantage of any stored context on the server. Session state is therefore kept entirely on the client. But django-rest-framework stores tokens in database (in authtoken_token table) and I delete a token to logout a user.If token is stored in server,is it really stateless? Or am I understanding it wrong? Thanks for answering! -

I have a model given below: class Listing(models.Model): account_name = models.ForeignKey(Account, on_delete=models.CASCADE, verbose_name='Account Name', null=True, blank=True) profile_username = models.CharField('Username', unique=True, max_length=200) class Meta: verbose_name = 'Listing' verbose_name_plural = 'Listings' def __str__(self): return self.profile_username profile_username is Instagram username.

I can't cut of image using "crop" of "pillow"
Question about django. Posted image from form was saved and cut it using "crop" of "pillow" then resize and save. the program was no problem in local, but it was not cuted as specified after deployed on vps (When I upload 5 images, the one or two images was not cuted as specified) . I just only deployed data of git. I don't understand the cause. Could you tell me, if you know the cause. Code print(int(x)) print(int(y)) print(int(w)) print(int(h)) pp = ImageTable.objects.filter(sort_id = st.sort_id) print(pp[count-1].image) im = Image.open('media/' + str(pp[count-1].image)) #'str(pp[count-1].image)' is for example like 'images/test.png' images path xx = int(x) + int(w) yy = int(y) + int(h) im = im.crop((int(x), int(y), int(xx), int(yy))) im.resize(size=(200, 200), resample=Image.BOX).save('media/' + str(pp[count-1].image)) I Tried About the code above. the code is looped by for function and upload five images. it upload different images for each loop because of count is plus 1 every loop. I confirmed x,y,w,h was as specified value by using print debug. Supplementary information I hardly changed, but I changed database to postgresql from db.sqlite3. Is this relevant. -

Posting form data with axios (Vuejs) to django forms.py and then to 3rd party service
As the subject reads above I'm trying to post the fields in a form. each field is bound with v-model and set in export default I can do a submit and then it does a post but when it hits Django it sends hardcoded data to the 3rd party service if I remove the hardcoded data in the payload the 3rd party service bombs out. but if I leave the hard coded data I get a response. views.py from django.views.generic import TemplateView from django.views.decorators.cache import never_cache from rest_framework import viewsets from django.http import Http404 from rest_framework.views import APIView from rest_framework.response import Response from rest_framework import status from .forms import DjangoForm import requests # Serve Vue Application index_view = never_cache(TemplateView.as_view(template_name='index.html')) class TestRest(APIView): def get(self, reqeust, format=None): thisdict = { "brand": "Ford", "model": "Mustang", "year": 1964 } print("GET request received") return Response(thisdict) def post(self, request, format=None): print("POST request received") url = "http://localhost:8080/" payload = "{\r\n \"prefix\":\"thanks dude\",\r\n \"length\":\"100\",\r\n \"temperature\":\"0.7\",\r\n \"top_k\":\"40\"\r\n}" headers = { 'Content-Type': 'application/json' } response = requests.request("POST", url, headers=headers, data=payload) return Response(response.text, status=status.HTTP_200_OK) def store_doPost(request): if request.method == 'POST': doPost = doPost(request.POST) Django_Form = DjangoForm(request.POST, request.FILES) if Django_Form.is_valid(): required_document_form.save() forms.py from rest_framework import serializers from django.db import models from django … -

No Access to files in S3 from Centos7 website on EC2
First time using AWS S3 here. I've been trying to figure this out the entire week but I just can't get my Django + NGINX site to display both my CSS and uploaded images from S3. I'm probably missing something but I just don't know exactly. I've looked into this, this, and this but I'm still unable to get things running. I have a Bucket Policy and a CORS Config in my bucket maybe you can take a look. What I have so far: My site works fine only without any CSS or other static files like images CSS and image file URLs are correct. They all direct to my S3 bucket. Image uploading has no problem saving to S3 To test, accessing each CSS/image manually from the browser returns the standard AccessDenied page from S3 I have an IAM role with the AmazonS3FullAccess policy applied to my EC2 instance All public access is blocked in my bucket My Bucket Policy For testing purposes, I created a user with AmazonS3FullAccess along with the role. Not sure if that's necessary... { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::<NUMBERS>:role/<MYEC2ROLE>", "arn:aws:iam::<NUMBERS>:role/<MYUSER>", ] }, "Action": "s3:*", "Resource": [ "arn:aws:s3:::<MYBUCKET>", … -
Editing of django form with primary key fields
I have a django model form for which I allowed partial form save since its a long form. Now I want the user to come back and complete the form later. There is one hindrance however that my database cannot accept duplicate entries with same primary key. So should I remove primary key in my database to solve this or is there another way to make it possible? Suggestions please. -
Django + gunicorn + nginx + supervisor -> upstream request timeout

Any ideas what could help me? Cheers! PS. Locally, Django is handling requests that take longer than 15 seconds, so it is not a Django issue. -
