A Guide to the Django ModelForm - Creating Forms from Models
Django ModelForms is a helper class that allows you to create a Form class from an existing Django model. It honestly sounds more complicated than it actually is to implement. Create a Django Model Add a model to models.py mysite > main > models.py from django.db import models # Create your models here. class Movie(models.Model): movie_title = models.CharField(max_length=150) release_year = models.IntegerField() director = models.CharField(max_length=100) movie_poster = models.ImageField(upload_to='images/', null=True) movie_plot = models.TextField() def __str__(self): return self.movie_title The example above is from How to use Django Models. The model contains CharFields, IntegerField, ImageField, and a TextField. The function at the bottom returns the movie's title as the display name in the admin so it's easy to identify each model object. Configure the project for media uploads mysite > mysite > settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') Add a URL for Django media file uploads in the settings if you have an ImageField or FileField in your models. mysite > mysite > urls.py from django.contrib import admin from django.urls import path, include from django.conf import settings #add this from django.conf.urls.static import static #add this urlpatterns = [ path('admin/', admin.site.urls), path('', include ('main.urls')), ] if settings.DEBUG: #add this urlpatterns … -

GraphQL subscriptions in Django with Ariadne and Channels
In this post we will see how to add GraphQL subscriptions to Django with Ariadne and Channels, and what it takes to work with the Django ORM in an asynchronous context. What is Ariadne? Ariadne is a GraphQL library for Python, which offers also an integration for Django. GraphQL is a data query language which allows the client to precisely define what data to fetch from the server and combine data from multiple resources in one request. In a sense, this is what we always did with REST APIs, but GraphQL takes this a step further, pushing more control to the client. What is Django Channels? Channels is a library which adds, among other protocols, WebSockets capabilities to Django. Setup and sample models This mini tutorial assumes you have a Django project where you can install Django Channels and Ariadne. My demo project has a sample model named Order, as follows: from django.db import models from django.conf import settings class Order(models.Model): class State(models.TextChoices): PAID = "PAID" UNPAID = "UNPAID" date = models.DateField() state = models.CharField(max_length=6, choices=State.choices, default=State.UNPAID) user = models.ForeignKey(to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE) To start off, with the virtual Python environment active, install Channels and Ariadne: pip install ariadne channels Next up, … -

How to use Python’s HTTPStatus with Django
A “magic number” is the anti-pattern of using a number directly rather than storing it in a descriptive variable name. In web code HTTP status codes are often used as magic numbers, perhaps because web developers memorize common codes such as 200 and 404. In Python, we can avoid such magic with descriptive references from the standard library’s http.HTTPStatus enum. Let’s look at two ways to use HTTPStatus in our Django code. 1. Creating Responses Django includes a bunch of HttpResponse subclasses for common status codes, but the list is deliberately non-exhaustive. If we need to return a status code for which a classes does not exist, we can use Python’s HTTPStatus with Django’s HttpResponse. For example, if one of our pages is unavailable due to legal reasons, so we want to return status code 451. We can do this with HttpResponse like so: from http import HTTPStatus from django.http import HttpResponse def taken_down(request): ... return HttpResponse( content, status_code=HTTPStatus.UNAVAILABLE_FOR_LEGAL_REASONS, ) If we find ourselves using a status code a lot in our project, we can create our own HttpResponse subclasses, as the documentation mentions. For example: from http import HTTPStatus from django.http import HttpResponse class HttpResponseLegallyUnavailable(HttpResponse): status_code = HTTPStatus.UNAVAILABLE_FOR_LEGAL_REASONS Additionally, … -

How to Start a Production-Ready Django Project
In this tutorial I’m going to show you how I usually start and organize a new Django project nowadays. I’ve tried many different configurations and ways to organize the project, but for the past 4 years or so this has been consistently my go-to setup. Please note that this is not intended to be a “best practice” guide or to fit every use case. It’s just the way I like to use Django and that’s also the way that I found that allow your project to grow in healthy way. Index Premises Environments/Modes Local Tests Production Project Configuration Requirements Settings Version Apps Configuration App Structure Code style and formatting Editor Config Flake8 isort Black Conclusions Premises Usually those are the premises I take into account when setting up a project: Separation of code and configuration Multiple environments (production, staging, development, local) Local/development environment first Internationalization and localization Testing and documentation Static checks and styling rules Not all apps must be pluggable Debugging and logging Environments/Modes Usually I work with three environment dimensions in my code: local, tests and production. I like to see it as a “mode” how I run the project. What dictates which mode I’m running the project … -
