While uploading i want to put a validation that, if visit for one customer is already uploaded then for same another wouldn't be uploaded and would raise a error like" Visit plan for this customer already exists on this date".

D.R.Y approach to splitting a queryset into many different sub groups?
I have a single query allnames = self.object.person_othernames.all().prefetch_related("nametype") This returns all the names related to a person's object, each related name has a "nametype" field ("English name", "stage name", etc). I want to display the names in the template which is no problem but if there are multiple names that use the same "nametype" then I want to separate them behind their "nametype" header. So if there are multiple names with the nametype "English name" then it would be displayed as: English Names: name1, name2 The approach I have tried already seems like it would work just fine but I feel like there would be a much better D.R.Y approach. So what I tried was to make a single query to the database using the code at the top, then I filtered down that queryset for each nametype. english_names = allnames.filter(nametype__nametype__iexact="english name") stage_name = allnames.filter(nametype__nametype__iexact="stage name") The problem with the above code is that I'd need to do this for every "nametype" and if there are many "nametypes" then each one would need to be individually filtered and sent through the context. So my inexperience is probably shining bright at the moment but if anyone has any suggestions I'd appreciate … -
Django: This site can’t be reached : localhost refused to connect
I am a newbie to the django and doing a course from udemy and got stuck at the admin page. I am unable to load the django default admin login page. It throws the following error: This site can’t be reached localhost refused to connect. I am still at the very beginning of the course and just created a function in the model.py file and made the migrations and tried accessing the default login page. Here's the code: from django.db import models class Student(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) email_id = models.EmailField(max_length=254) phone_no = models.IntegerField() I have tried all the steps mentioned in the previous answers. But still, the issue isn't resolved. I strongly feel that it is due to system settings regarding the localhost. No error displayed in the command prompt. I have changed my firewall settings, tried adding localhost, '*' and every other alternative that I've found. Please help..!! Thanks, -

Django register form POST data not validated by view in production?
For some reason the POST data from my Django app's user sign up form doesn't get validated by the signup view. It works perfectly in development on my local machine, but not in production. I have also inspected the web content and the POST data gets created but the page just reloads an empty form.

How to change some stuff from the css file for my form?
I have a file that extends my base HTML file and this file contains a form. I want to create a margin for the form and also change the color of the submit button and form text box to match the theme of my website. How do I go about doing this in my CSS file?

How to get a value of a foreign key?
I recently started to learn django, so I am not even sure how to ask this question. I want to build an api and I am using django rest framework. Now I have two main models Product and Category. class Category(models.Model): id = models.CharField(max_length=100, primary_key=True) name = models.CharField(max_length=100) class Product(models.Model): id = models.CharField(max_length=100, primary_key=True) title = models.CharField(max_length=100) category = models.ForeignKey(Category, on_delete=models.CASCADE) price = models.FloatField(default=0.0) And I have some functions @api_view(['GET']) def productList(request): products = Product.objects.all() serializer = ProductSerializer(products, many=True) return Response(serializer.data) @api_view(['POST']) def addProduct(request): serializer = ProductSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) All of these seems to work fine and I am getting a response from an api, but when I try to pull category name from a response I only get id of a category and not its name. Can you please help me figure this out? Thank you -
Django Channels doesn't detect WebSocket request with NGINX
I am deploying a website on AWS. Everything works fine for HTTP and HTTPS. I am passing all requests to Daphne. However, incoming websocket connections are treated as HTTP requests by Django. I am guessing there is some header that isn't set in Nginx, but I have copied alot of my nginx config from tutorials. Nginx Config: upstream django { server 127.0.0.1:9000; } server { listen 80; server_name 18.130.130.126; return 301 https://$host$request_uri; } server { listen 443 ssl; server_name 18.130.130.126; ssl_certificate /etc/nginx/certificate/certificate.crt; ssl_certificate_key /etc/nginx/certificate/private.key; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; location / { include proxy_params; proxy_pass http://django; } } Daphne is binded to 0.0.0.0:9000. Channels has very basic setup. A ProtocolTypeRouter, with AuthMiddlewareStack and then URLRouter, as shown on the Channels tutorial. And then a Consumer class. I am using redis for channel layer, but that doesn't seem to be a problem. This is some data about the request on response from fiddler. The request headers say Upgrade to websocket, but it returns a 404 HTTP request, as it doesn't see it as a websocket request. Thanks for any help. -

Cannot make the views counter
I'm Trying to create a Views Counter in my django blog. Their are 3 apps in the project. The views counter on the writings app works fine but on the blog app it throws an error 'NoneType' object has no attribute 'views' and shows the error at post.views+=1. However the same code works in the writings app. I cannot find where the problem lies. Maybe the code is returning a empty set that's why it's not working but if so then why the code works when I remove just this views counter code?
