Creating a table to display rows from a database
I'm trying to create a table that will display the rows of a database called patients and I have created this using Django as the back-end and react as the Front-End. When I try to implement the code I have created thus far the only thing I'm seeing on the webpage is my table header. It should be noted that I have checked sqlite studio and there is data stored in the table. I've checked on PostMan and my Get, POST,PUT, and DELETE methods are all working fine and do what I intend them to do. I'm using Firefox as my browser and I've checked the network tab under inspection, but nothing is being sent to the back-end. I will attach my initial attempt at the front-end webpage import React, {Component} from 'react' export class ViewPatients extends Component{ constructor(props){ super(props); this.state = { patient: [], }; } fetchPatients = () => { fetch('http://127.0.0.1:8000/patient') .then(response => response.json()) .then(data=> { this.setState({patient:data}); }) .catch(error => { console.error("Error Fetching Patients") }); }; componentDidMounted(){ this.fetchPatients(); // this.refreshList(); } render(){ const { patient } = this.state; return( <div> <table> <thead> <tr> <th>ssn</th> <th>address</th> <th>age</th> <th>gender</th> <th>race</th> <th> medical history </th> <th>occupation</th> <th>phone number</th> <th>username</th> </tr> </thead> … -
How to update Django url (to include data/param) after POST
I have a search form (place names) on my home page with an auto-complete dropdown on the search input field. When the user presses enter after selecting an item in the search box the form does a post. When the results return I still have the same url (https://mywebsite.com). How do I get the selected search entry (a location name) to appear in the url so users can book mark it for later use? eg https://mywebsite.com/mylocation I have got the GET code working to get the location in the url - just don't know how to update the url to add the location string after the search form post. I am new to Django so really winging it. Have searched but found no discussion on this even in the Django docs. -
Removing user tags in django
I have been using taggit feature in django for hobbies . Each user can add his hobbies in his profile and tags will be created like tennis or watching movies. I have created a cloud to show him the tags that he has already added : <div class="rounded-tag-container"> {% tag_edit person_id=person.id %} </div> this is also html for this cloud: {% for tag in tags %} <span class="rounded-tag"> <a href="#" style="color:blue;"> {{ tag.name }} </a> <span class="close-button" onclick="removeTag(this, '{{ tag.name }}')"> <strong>×</strong></span> </span> {% endfor %} <script> function removeTag(element, tag_name) { element.parentNode.remove(); $.ajax({ type: 'POST', url: '/hobbies/' + person_id + '/', data: { tag_name: tag_name, csrfmiddlewaretoken: csrftoken }, success: function(response) { console.log(response); }, error: function(error) { console.error('Error deleting tag:', error); } }); } also In my hobbies view I defined tag_name: tag_name = request.POST.get('tag_name') if tag_name : try: person.tags.remove( tag_name) messages.success(request, 'Tag deleted successfully') except Tag.DoesNotExist: messages.error(request, 'Tag not found') else: messages.error(request, 'Tag name not provided') when the user clicks on the close button of each tags,it will be removed from the client side and then clicks on submit,it must remove the tag in post request from db, but it does not remove it from database! -

Django "request.user" always returns "AnonymousUser" even though sessionid gets added and is valid
So I made a discord oauth2 login without using a User model like AbstractUser or AbstractBaseModel, when I first made it a month ago, it worked fine and the login worked flawlessly! (Profile loaded, username shown, etc.) I don't know what I changed a week ago, but it no longer works. The custom authentication works and authenticate() returns a new DiscordUser model, then it gets passed to login() with the custom backend argument. The sessionid gets saved in the cookie storage when I check it. When I also check the DB, the sessionid is there and therefore a valid sessionid. Yet when I print out the request.user or request.user.is_authenticated I always get AnonymousUser and False. I don't understand. I followed this video: https://www.youtube.com/watch?v=KKJyU7JGuVk&list=PLwu1p7jK5YEUhRNJpzLYa8nhWRnJdPR6p auth.py: from django.contrib.auth.backends import BaseBackend from .models import DiscordUser class DiscordAuthenticationBackend(BaseBackend): def authenticate(self, request, user) -> DiscordUser: try: user = DiscordUser.objects.get(pk=user["id"]) return user except DiscordUser.DoesNotExist: new_user = DiscordUser.objects.create_discord_user(user) new_user.save() return new_user managers.py from django.contrib.auth import models from datetime import datetime from utils.cipher import XChaCha20Manager from base64 import b64encode class DiscordUserOAuth2Manager(models.UserManager): def create_discord_user(self, user): # encrypt tokens with the same nonce encrypted_access_token, nonce = XChaCha20Manager().encrypt(user["access_token"].encode()) encrypted_refresh_token, _ = XChaCha20Manager(nonce=nonce).encrypt(user["refresh_token"].encode()) new_user = self.create( user_id=user["id"], username = f"{user["username"]}", avatar = … -
Sending the output of two filters in one querystring to filter a django model
I have two filters. I have used pokemon as the example: Filter A: filters the pokemon trading card sets e.g. Base set, Fossil, Jungle Filter B: Filters the pokemon stats, e.g. pokemon types, name of pokemon. Those two filters have two submit buttons, I want them to work together. If I hit the submit for filter B it sends: ?name=Bulbasaur&type= If I hit the submit for filter A it sends: ?sets=Jungle What I want is: ?name=Venusaur&type=&sets=Fossil I'm using the module django-filters, I construct a FilterSet class for each filter that I initiate in the view. pokemon_sets = PokemonSets.objects.all() pokemon_filter = PokemonSetsFilter(request.GET, queryset=pokemon_sets) sets = pokemon_filter.qs.values_list('key_id', flat=True) pokemon = PokemonDatabase.objects.filter(sets__in=sets) pokemon_filter = PokemonFilter(request.GET, queryset=listings) Any insight will help greatly! I tried filtering the pokemondatabase model to the output of the filter to chain the filters to filter the model, but only one filter works at a time. -
How to dynamically set the access token expiration in Django Rest Framework Simple JWT?
I am working on a restful web application using Django Rest Framework and need to implement a mechanism to check every 15 minutes if the user has been active in order to extend their token expiration. If the user has not been active, their access token should become invalid. I am using Djoser in conjunction with Simple JWT as the authentication backend. Can someone provide guidance on how to achieve this? Thank you. I have tried creating a custom middleware to track the user's activity for the last 15 minutes but do not know how to effectively manage the user's jwt access token based on the user activity. -
Run Tests with Coverage "TypeError: Parameters to Generic[...] must all be type variables"
When running tests with coverage using PyCharm on django (python) project, im having the following error: Traceback (most recent call last): File "C:\Program Files\JetBrains\PyCharm 2023.1.2\plugins\python\helpers\pycharm\django_test_manage.py", line 6, in <module> from django.core.management import ManagementUtility File "C:\Users\User\Project\Code\venv39-master\lib\site-packages\django\core\management\__init__.py", line 13, in <module> from django.apps import apps File "C:\Users\User\Project\Code\venv39-master\lib\site-packages\django\apps\__init__.py", line 1, in <module> from .config import AppConfig File "C:\Users\User\Project\Code\venv39-master\lib\site-packages\django\apps\config.py", line 7, in <module> from django.utils.deprecation import RemovedInDjango41Warning File "C:\Users\User\Project\Code\venv39-master\lib\site-packages\django\utils\deprecation.py", line 5, in <module> from asgiref.sync import sync_to_async File "C:\Users\User\Project\Code\venv39-master\lib\site-packages\asgiref\sync.py", line 130, in <module> class AsyncToSync(Generic[_P, _R]): File "C:\Program Files\Python39\lib\typing.py", line 277, in inner return func(*args, **kwds) File "C:\Program Files\Python39\lib\typing.py", line 997, in __class_getitem__ raise TypeError( TypeError: Parameters to Generic[...] must all be type variables class SimpleTest(TestCase): def test_basic_addition(self): self.assertEqual(1 + 1, 2) According to what i have read, its probably a version conflict between typing and asgiref. Here are the versions I'm using: typing_extensions 4.8.0 asgiref 3.7.2 Python 3.9.13 Django 3.2.20 Whats weirder is that running the the same test with coverage (using lib coverage.py) from terminal, everything works. coverage run ./manage.py test -v 3 According to Jetbrains, the PyCharm IDE uses the exact same library for coverage...What could be the solution? -
Django 4.2 , GenericIPAddress and CIDR
Im updating a project from: Python 3.9 + Postgres 13 + Django 4.0.6 + psycopg2 TO Python 3.11 + Postgresql 15 + Django 4.2 + psycopg3 I have a big problem with GenericIPFields. It seems that it doesn't support cidr anymore. When I try to save an ORM with a cidr, I get: ValueError: '10.255.96.48/28' does not appear to be an IPv4 or IPv6 address I need that INET FIELD on DB with cidr to make queryes like: Subnet.objects.filter().extra(where = [ "cidr::inet >>= inet '"+self.ip_address+"'" ]) and other cidr related queries. -
