Django queryset to show values every month
I'm making a Django APP (required) to calculate every month the profits and losses. There's a feature that I wanted to put that in N months you'll be paying the value/N (i.e: $100/5 that equals to $20 per month). This feature would be like a Bank APP shows how many you have yet to pay (i.e: from this month to October) By the way, there's only one record from the losses (I'm trying not to change this) So far so good, but the record appear only in the month of my search (view below) and when I try to use: Account.objects.filter(date__year__gte=y) or Account.objects.filter(date__month__gte=m) or Account.objects.filter(date__year__lt=y) or Account.objects.filter(date__month__lt=m) The record shows the entire year or the months whose are greater or less than the month saved (with no filter, so if it's from July to November, it'll show until December or in January) View.py def account(request, pk): search = f"{datetime.now().year} - {datetime.now().month:02}" account = Account.objects.get(id=pk) ctx = { 'search': search } if request.GET.get('month'): search = request.GET.get('month') y, m = search.split('-') ctx.update({ 'search': search }) date_loss = filter_by_model_date(Loss, m, y) date_profit = filter_by_model_date(Profit, m, y) profit = filter_by_account(date_profit, account) loss = filter_by_account(date_loss, account) ctx.update({ 'profit': profit, 'loss': loss }) return render(request, 'account/account.html', … -

How to apply an arbitrary filter on a specific chained prefetch_related() within Django?
I'm trying to optimize the fired queries of an API. I have four models namely User, Content, Rating, and UserRating with some relations to each other. I'm going to the respective API to respond all of the existing contents alongside their rating count as well as a the score of given by a specific user to that. I used to do something like this: Content.objects.all() as a queryset but I realized that in the case of the huge amount of data tons of query will be fired. So I've done some efforts to optimize the fired querie using select_related and prefetch_related. However I'm dealing with an extra python searching that I hope remove that by a controlled prefetch_related() — applying a filter just for a specific prefetch in a nested prefetch and select. Here are my models: from django.db import models from django.conf import settings class Content(models.Model): title = models.CharField(max_length=50) class Rating(models.Model): count = models.PositiveBigIntegerField(default=0) content = models.OneToOneField(Content, on_delete=models.CASCADE) class UserRating(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True, on_delete=models.CASCADE ) score = models.PositiveSmallIntegerField() rating = models.ForeignKey( Rating, related_name="user_ratings", on_delete=models.CASCADE ) class Meta: unique_together = ["user", "rating"] Here's what I've done so far: contents = ( Content.objects.select_related("rating") .prefetch_related("rating__user_ratings") .prefetch_related("rating__user_ratings__user") ) for c … -
Why is only the first React component rendering in my multi-page in Django app?
I am trying to render a secondary component to a different URL in my React frontend of my Django app. The URLs seem to be set up correctly, as the page title is changing accordingly and no errors are thrown, but the page itself is blank. My components are being loaded by importing in index.js in the components directory. #index.js import App from './components/App'; import Viz from './components/Viz'; #urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index), path('viz/', views.getviz) ] For the simplicity of testing, I made the components a copy so I know it works. // App.js import React, { Component, Fragment } from 'react'; import ReactDOM from 'react-dom'; import Header from './layout/Header'; import Dashboard from './splits/Dashboard'; import Alerts from './layout/Alerts'; import { Provider } from 'react-redux'; import { Provider as AlertProvider } from 'react-alert'; import AlertTemplate from 'react-alert-template-basic'; import store from '../store'; //Alert Options const alertOptions = { timeout: 3000, position: 'bottom center' } class App extends Component { render() { return ( <Provider store={store}> <AlertProvider template={AlertTemplate} {...alertOptions}> <Fragment> <Header /> <Alerts /> <div className="container"> <Dashboard /> </div> </Fragment> </AlertProvider> </Provider> ); } } ReactDOM.render(<App />, document.getElementById('app')) The only difference with the other … -
How to use media files during deployment (django)?
Need help with managing media files during deployment. I've read several articles and documentation regarding to subject, but can't fix my particular site: tis, this and django documentation. Guess I've missed some obvious thing, or it could be misprint in code (link to media files). So, I've deployed site on django, using gunicorn and nginx. When users download some picture on site it save in media directory. models.py class News(models.Model): title = models.CharField(max_length=128) content = models.TextField(blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) photo = models.ImageField(upload_to='photos/%Y/%m/%d', blank=True) settings.py DEBUG = False ...

I guess it could be some problem in pass to media file. I've checked link in page - it's correct. <img src="photos/2022/05/10/kitten.jpg"> And this file is there. Can't download picture on page. How to download and use media files correct? I'll be glad to get advice or link to any documentation regarding to this subject. Thank you in advance. -

Django project to display multiple styles, one at a time
I have a project in Django. One of the pages uses a ui selector, that is to say, clicking a button changes the style displayed. The button is implemented using javascript. It is done such that there are two divs both initially hidden: <div class="c2" style="display: none"> content </div> <div class="c3" style="display: none"> content </div> The code within those divs uses Django commands to iterate over the same stuff. However, switiching to the second style (I tested putting each div first and it is always the second div) displays a page without all the data that is iterated over again. How does one fix that? -
