jQuery & Django, update div with different intervals
I've been making a Moon Info Display for a project of mine. I've been using Python to calculate the moon info values and used Django to send the info to the front-end.

However, now I wanted to update some part of the page with different interval, how would I do this? My jQuery code is as follows: $(document).ready(function() { $.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh var my_refresh = setInterval(function() { $('#moonphase').load('/getPhase/'); $('#alti').load('/getAlt/'); $('#az').load('/getAz/'); $('#elong').load('/getElong/'); $.get( '/getImage/', function(data){ img = parseInt(data); if (img === 1){ document.getElementById("imgphase").src = "{% static "lunarphase/0_0.png" %}"; } else if (img === 2){ document.getElementById("imgphase").src = "{% static "lunarphase/2_0.png" %}"; } else if (img === 3){ document.getElementById("imgphase").src = "{% static "lunarphase/5_0.png" %}"; } else if (img === 4){ document.getElementById("imgphase").src = "{% static "lunarphase/8_0.png" %}"; } else if (img === 5){ document.getElementById("imgphase").src = "{% static "lunarphase/14_0.png" %}"; } else if (img === 6){ document.getElementById("imgphase").src = "{% static "lunarphase/17_0.png" %}"; } else if (img === … -

Django Rest Framework request header based permission
I'm building a Django app with Django Rest Framework to host it on my organisation's domain. The domain implements a custom authentication protocol. When someone accesses the domain, say to app1.domainname.com, they are redirected to the organisation's login page (login.domainname.com) and they have to log in with their staff account. After the user is authenticated, the user is redirected back to their initial destination (app1.domain.com). The information of the user is then stored in some custom header fields of the HTTP request sent to the app. E.g. GET / HTTP/2 Content-Type: User-Agent: ... ... X-Username: johndoe1 X-Firstname: John X-Lastname: Doe X-Email: johndoe@domainname.com etc. I'm trying to implement custom permission for my REST API that looks for these fields in the headers, and then authorise the user based on their user information. This is what I'm currently having: from rest_framework.permissions import BasePermission allowed = ['johndoe1', 'dicksmith2', 'username3'] class CutomPerm(BasePermission): message = "You don't have permission to access this object" def has_object_permission(self, request, view, obj): print(request.headers) username = request.headers['X-Username'] return username in allowed But when I run the server, it seems like the custom headers are passed through to the backend. For some requests they are, but ultimately the user is not … -

I am attempting to create a model with an image input that is to be resized and hashed on save. However, I appear to to have created an infinite recursive call. I am basing the code for my resize_and_hash_image() method off of this answer to a previous question of mine. Is there a way I can save the image without calling self.instance.save()? Any help is appreciated. models.py import hashlib from base64 import b16encode from functools import partial from io import BytesIO from PIL import Image from django.db import models class Person(models.Model): prefix = models.CharField(blank=True, null=True, max_length=5) first_name = models.CharField(max_length=35) last_name = models.CharField(max_length=35) suffix = models.CharField(blank=True, null=True, max_length=5) image = models.ImageField(default=None, upload_to='people/') _image_hash = models.BinaryField(blank=True, null=True, default=None, max_length=16) bio = models.TextField() phone = models.CharField(max_length=10) email = models.EmailField() def __str__(self): return self.full_name def save(self, *args, **kwargs): if self.image: self.resize_and_hash_image() super().save(*args, **kwargs) def hash_file(self, file, block_size=65536): hasher = hashlib.md5() for buf in iter(partial(file.read, block_size), b''): hasher.update(buf) return hasher.digest() def resize_and_hash_image(self): img = Image.open(self.image).convert('RGB') width, height = img.size longest, shortest = 960, 720 if (width >= height and (width > longest or height > shortest)) or (height > width and (height > longest or width > shortest)): if width > height: if (height * …
