How do I create a Django model for a chatroom in python?
Just letting you all know that I am very inexperienced with web development and so I decided to start a project in which I am making an application similar to Discord in which people can go to chat rooms and voice chat each other. From research, I decided to use Django (now with sockets). I started my project making the models first since that is the easiest for me to understand now. I was easily able to create a User Profile like so: from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from django.dispatch import receiver import django class UserProfile(models.Model): user_name = models.OneToOneField(User, related_name='user profile', on_delete=models.CASCADE) photo = models.ImageField(null=True, blank=True, default='random_14-512.webp') status = models.CharField(default='This is my status', max_length=255) is_online = models.BooleanField(default=False) objects = models.Manager() @receiver(post_save, sender=User) def create_user_profile(self, sender, instance, created, *args, **kwargs): if (created): UserProfile.objects.create(user_id=instance.pk) class ChatRoom(models.Model): pass but I have no idea how I can create a model for the chatroom. I can give it a name easily and such, but if I use models.CharField, the first parameter is the user. If anyone can point me in the right direction on how I can create the model for the chat room, that would be much … -

Error When Parsing Incoming Email Via SendGrid
I am successfully set up a webhook with django/python to parse incoming SendGrid emails. However, I am getting an error and cannot parse the data I receive. The error suggest the body I am receiving is empty, which is not the case. @csrf_exempt def receive_email_hook(request): print("request.body: ",request.body) try: data = json.loads(request.body.decode('utf-8')) sender = data['from'] recipient = data['to'] subject = data['subject'] body = data['html'] print("SUBJECT: "+str(subject)) return HttpResponse(status=200) except Exception as e: print("ERROR: "+str(e)) return HttpResponse(status=400) My error is: ERROR: Expecting value: line 1 column 1 (char 0) When I print the request.body, I get: request.body: b'--xYzZY\r\nContent-Disposition: form-data; name="headers"\r\n\r\nReceived: (...)

I´m trying to include a local javascript in my react component, and the functionality of said component is inconsistent
I have a component in react called consentBottom, where I am trying to import an external javascript file called consent. I can get the functionality of the consent file to work, but once I press the "go back" button and then immediately "go forward" button in the browser, the functionality from the javascript file stops working. Bear in mind that there is no function to export manually from this file. It´s full of functions, using jquery, that get invoked when buttons or forms that have a particular class or id names are pressed or submitted. This is a file integraded from another environment, and the project is being transferred from flask to the setup with django on the backend and react on the frontend. The pipeline of my project now is: index.html -> (calls element by div with id=root) index.js -> has the following call to the App component: <React.StrictMode\> <App /> </React.StrictMode\> App.js -> has the following url routes: <BrowserRouter> <Route path='/' element={<Home languageState={languageState}/>} /> <Route path='/consent' element={<Consent languageState={languageState}/>}/> <Route path='/authenticate-presenter' element={<AuthenticatePresenter languageState= {languageState}/>}/> <Route path='/main-complaints' element={<MainComplaints languageState={languageState}/>}/> <Route path='/questions' element={<Questions languageState={languageState}/>}/> </BrowserRouter> Home (url="/") -> Has a main component homeMainPage, which calls another component homeBody inside the jsx … -

How to change the time format when providing an initial value in Django?

How to decrease an image size when loading the page in Django backed web application?
My classic Django application is a simple blog post website showing the posted images line on a start page. I allow users to upload images to their posts up to 100 Mb to have the ability to download the image if someone likes it. But I encountered a significant loading time on the start page due to image sizes. I use CSS object-fit feature to make images small for good fitting on a common start page, but the image size in Mb doesn't change. It is still downloading full-sized images and after just shaping them with CSS. As a result, I have very slow page loading. I used a standard model pattern in the Django backend: image = models.ImageField...and then just render it on a page template with post.image.url tag. So I want the original-sized image loads if users click on the image only. Please advise how to fix that. -

Django navigation problems because of url
I have created a web app using the Django framework. I created a function to iterate through my installed apps and display the desired apps as links to said app, without having to hard-code the link to each app (the function finds the link and displayed app name) On my home page I have links to my other apps, and they all work, but once I enter an app, the links to every other app do not. The function still does what it is supposed to, but when the links are clicked, the url of the clicked app is appended to the end of the current url instead of replacing it and directing me to the desired app. How to I get the clicked url to replace the current url and not just append to it? I designed the names of my urls and apps to work with this function, and that works, but I did not expect the clicked links to append themselves to the current url. -

Application Error - Heroku logs - Need Help Interpreting
I created a django project months ago deployed it to Heroku. It functioned well for quite a few months, but when Heroku changed to a paid service my site was knocked off. I've been trying to resurrect it and have gotten part of the way. The website allows students to practice reading musical pitches on the note staff and finger board (for orchestra instruments). When I visit my site after deployment, it takes me to a landing page where I can choose to sign up, login, or go to a free games page. Both Login and Registration pages load, but when clicking submit the redirect times out. It should go to the main orch_quiz page which contains the quizzes for the students. Instead I get an Application Error page that suggests I use the heroku logs --tail command. When I run that, I understand the H12 is a timeout error code, but it does not explain why the timeout is happening. I'm a novice at building websites so any assistance or guidance would be greatly appreciated! The project is deployable and does without noticeable error. The issues seems to be in accessing the orch_quiz app. I've run pip freeze to … -

Django handler404 not called on raise Http404
I've setup a custom 404 handler in my Django views @api_view(["GET"]) def handler_404(request: HttpRequest, exception: Exception = None): return Response({"status": 404, "error": "Not Found"}, status=404) It works perfectly if I visit an invalid path; however it is not called when I raise Http404 exceptions, for example with the get_object_or_404 method - the default 404 response is returned instead. I implemented a workaround by adding a 404 handler in my middleware but I'd like to know if there's something I'm doing wrong and how to intercept Http404 exceptions with it def process_response(self, request, response): if response.status_code == 404: # for some reason views.handler_404 doesn't catch Http404 Exceptions return JsonResponse({"status": 404, "error": "Not Found"}, status=404) This is what my urls file looks like (as I said the handler works fine on most 404 responses) handler400 = api.views.handler_400 handler403 = api.views.handler_403 handler404 = api.views.handler_404 handler500 = api.views.handler_500 To sum it up, I tried adding the handler in my urls file but it is not called upon Http404 exceptions.

What should Authenticate Fetch from a User?
I joined a group that has been using Django and I was just curious for some performance aspects of user fetching for Authentication. The User objects have some foreignkeys/manytomany fields attached to them. I learned about the prefetch_related / select_related. So if I want to get everything of a user instance, that would result to about 10 queries. So my question is about API / REST Design. Should my auth only do 1 Query ( select User) or should it fetch alle the stuff that could be useful for other endpoints? Each endpoint uses the CustomAuthentication, so the queries would be executed for each API call. Is ist better to let people take care of a second well designed query at the endpoint, or should I provide them with alle variables on each endpoint autmatically ? Thanks in advance. This question is performance related. I tracked the requests with SILK and was not happy about the performance for retrieving Users -
How to return a list of objects using a Django REST API post request?
I am new to using REST API's and am trying to create an API where I can make a POST request containing keywords, which should then return a list of articles related to that keyword.
