How can i take user input validate the input using values in a dictionary and then add the corresponding value to the querystring in the API
I am building a web app that takes users' input and then returns the result using Google Finance API. My problem is I do not know how to write this in my views.py file that way when a user types in a currency. someapp/coins.py coins = [ {"Ethereum": "ETH-USD"}, {"Bitcoin": "BIT-USD"}, {"Litcoin": "LIT-USD"}, {"Solona": "SOL-USD"}, {"Binance": "BNB-USD"}, {"Ripple": "XRP-USD"}, {"XRP": "XRP-USD"}, {"Cardano": "ADA-USD"}, {"Dogeoin": "DOGE-USD"}, {"Chainlink": "LINK-USD"} ] this is the file that has the tickers needed to get results from the google finance api. So I am trying to check the users input with one of the keys in this list and then add the value which is the ticker needed for the search api to the querystring used in the the GET request. someapp/views.py from django.shortcuts import render import requests from django.views import generic from django.views.generic import TemplateView from django.http import HttpResponse from coins import coins # Create your views here. def index(request): return render(request, 'index.html') def news(request): if request.method == 'POST': crypto = 'POST' if crypto == coins[0:]: querystring.append() # not sure if this is the right thing to do else: pass url = "https://google-finance4.p.rapidapi.com/ticker/" **querystring = {"t":"ETH-USD","hl":"en","gl":"US"}** headers = { "X-RapidAPI-Key": "31c5541e87msh0684494d7f7396fp117984jsn574856ff6d0c", "X-RapidAPI-Host": "google-finance4.p.rapidapi.com" } response … -
Django celery task repeats every hour, it should be executed only once per day
The course_message_schedule_task runs every day at 04:00:00. In it, we register the course_message_send_task to run at 10:00:00 every day.

I am aggregating multiple outputs from models into the same table. So I am looking for a hostname_id, which ties the models together, and then displaying the output.

How may I convert a Many to Many field into JSON Format in Django
I am working with APIs based in REST Architecture. I know Django has a framework to work with this APIs but my homework is do it from scratch. I got an API of a movies site where users can go and search information about a bunch of movies and i am trying to get the data into JSON format from the model Movie which has a Many-to-Many relationship whith the Actor model. I am using Class-based views for this. The code from my models.py and views.py files is nested below: class Actor(models.Model): full_name = models.CharField(max_length=125) role = models.CharField(max_length=125) def __str__(self): return self.full_name class Movie(models.Model): ACTION = 'AC' DRAMA = 'DR' COMEDY = 'CM' SCIENCE_FICTION = 'SF' THRILLER = 'TR' RELIGIOUS = 'RG' GENRE_CHOICES = [ (ACTION, 'Accion'), (DRAMA, 'Drama'), (COMEDY, 'Comedy'), (SCIENCE_FICTION, 'Ciencia Ficcion'), (THRILLER, 'Triler'), (RELIGIOUS, 'Religioso') ] title = models.CharField(max_length=155, blank=False) synopsis = models.TextField(max_length=1000, blank=True) genre = models.CharField(max_length=100, choices=GENRE_CHOICES, default='', blank=False) tag = models.JSONField(default=dict, blank=True) actors = models.ManyToManyField(Actor, related_name='movies', blank=True) def __str__(self): views.py from django.views import View from django.http.response import JsonResponse from .models import Movie from django.utils.decorators import method_decorator from django.views.decorators.csrf import csrf_exempt import json class MovieView(View): @method_decorator(csrf_exempt) def dispatch(self, request, *args, **kwargs): return super().dispatch(request, *args, **kwargs) def … -
CORS Problem using Django backend with Angular app
I'm using Django REST as a backend for my Angular app. When I make a call to API, I get CORS error. I set up all the CORS configuration in backend side. In settings.py file like: CORS_ORIGIN_ALLOW_ALL = False CORS_ALLOW_CREDENTIALS = True CORS_ALLOW_METHODS = list(default_methods) CORS_ALLOW_HEADERS = list(default_headers) + [ 'Access-Control-Allow-Origin', 'app-version' ] My CORS origin whitelist url is my angular app url and port = https://localhost.com:8002 Also I added corsheaders to INSTALLED APPS and middleware too. Here is my angular request: const url = 'https://local-django-api.com:8004/get-data'; return this.http.get<GetResponseInterface<any>>(`${url}`, { headers: { 'Access-Control-Allow-Credentials': 'true', 'Access-Control-Allow-Origin': '*', 'Content-Type': 'application/json', }, }); Note: When I try to make an API call using Postman to the same url, it successfully returns a value. Does anyone have an idea about this problem. Thanks in advance for any help. -
Django template does not output datetime
I'm currently on my way of learning some django version is 4.1. I created a simple page which displays all objects inside a database table. Everything works as wanted, but only on my local machine. On the remote machine only pages without any objects/models which contain at least one datetime database field work. So my question is, how do i find out the error. From the "host" I only get the following response if I use any datetime in the template (first part always changes but the "esponse" part is always the same): ��esponse received from application On the local machine I get a correct list of objects with their attributes. I use the same database, so all schema and data is the same. I tried around like 3 hours now and I'm out of ideas. The /admin page also does not work on the webhost only when I visit the localhost it can display output (my guess is also datetime). The ONLY thing I found out by now is, that if I get an object with a datetime field and I use the following code, I can get the view to render the following: obj = Example.objects.first() field_value = …
