As [announced](https://www.djangoproject.com/weblog/2023/sep/18/django-50-alpha-1-released/) on the official **Django** site, the **Django 5.0** Version is out. The changes provided in this version are listed below. Curious minds and cutting-edge developers can test the new features by using the latest Django 5.x release: ```bash $ pip install Django==5.0a1 ``` In order to make this article more useful, here is an open-source Django Starter already updated to use `django==5.0a1` version and deployed on Render via a CI/CD flow: - 👉 [Django v5.x Datta Able](https://github.com/app-generator/django-v5-datta-able) - `Source Code` - 👉 [Django v5.x Datta Able](https://django-v5-datta.onrender.com/) - `LIVE Demo` ![Django v5.x Datta Able - Free Starter updated to Django 5.x Version](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/yd9jth7qqm753sgamw52.png) --- > ✅ Python Compatibility **Django 5.x** supports Python 3.10, 3.11, and **3.12**. Please note the 4.2.x versions are the last to support Python 3.8 and 3.9. --- > ✅ Facet filters in the admin [Facet](https://docs.djangoproject.com/en/dev/ref/contrib/admin/filters/?ref=blog.appseed.us#facet-filters) counts are now shown for applied filters in the admin change list when toggled on via the UI. This behavior can be changed via the new [ModelAdmin.show_facets](https://docs.djangoproject.com/en/dev/ref/contrib/admin/?ref=blog.appseed.us#django.contrib.admin.ModelAdmin.show_facets) attribute. --- > ✅ Simplified templates for form field rendering **Django 5.x** introduces [two new concepts that simplify the rendering](https://docs.djangoproject.com/en/dev/topics/forms/?ref=blog.appseed.us#reusable-field-group-templates) of the related elements of a Django form field such as its label, widget, help text, and errors. - "field group" - "field group templates" **Here is the official coding sample**, provided by the RN: ```python ``` --- > ✅ Database-computed default values The new field added, [Field.db_default](https://docs.djangoproject.com/en/dev/ref/models/fields/?ref=blog.appseed.us#django.db.models.Field.db_default), parameter sets a database-computed default value. **Here is the official coding sample**: ```python from django.db import models from django.db.models.functions import Now, Pi class MyModel(models.Model): age = models.IntegerField(db_default=18) created = models.DateTimeField(db_default=Now()) circumference = models.FloatField(db_default=2 * Pi()) ``` --- > ✅ Database generated model field The new [GeneratedField](https://docs.djangoproject.com/en/dev/ref/models/fields/?ref=blog.appseed.us#django.db.models.GeneratedField) allows the creation of database-generated columns. **Here is the official coding sample**: ```python from django.db import models from django.db.models import F class Square(models.Model): side = models.IntegerField() area = models.GeneratedField(expression=F("side") * F("side"), db_persist=True) ``` --- > ✅ Options for declaring field choices [Field.choices](https://docs.djangoproject.com/en/dev/ref/models/fields/?ref=blog.appseed.us#django.db.models.Field.choices) (for model fields) and [ChoiceField.choices](https://docs.djangoproject.com/en/dev/ref/forms/fields/?ref=blog.appseed.us#django.forms.ChoiceField.choices) (for form fields) allow for more flexibility when declaring their values. In previous versions of Django, choices should either be a list of 2-tuples, or an Enumeration types subclass, but the latter required accessing the .choices attribute to provide the values in the expected form Django 5.0 adds support for accepting a mapping or a callable instead of an iterable, and also no longer requires .choices to be used directly to expand [enumeration types](https://docs.djangoproject.com/en/dev/ref/models/fields/?ref=blog.appseed.us#field-choices-enum-types). **Here is the official coding sample**: ```python from django.db import models Medal = models.TextChoices("Medal", "GOLD SILVER BRONZE") SPORT_CHOICES = { # Using a mapping instead of a list of 2-tuples. "Martial Arts": {"judo": "Judo", "karate": "Karate"}, "Racket": {"badminton": "Badminton", "tennis": "Tennis"}, "unknown": "Unknown", } def get_scores(): return [(i, str(i)) for i in range(10)] class Winner(models.Model): medal = models.CharField(..., choices=Medal) # Using `.choices` not required. sport = models.CharField(..., choices=SPORT_CHOICES) score = models.IntegerField(choices=get_scores) # A callable is allowed. ``` --- > ✅ Other minor changes - **django.contrib.admin** - jQuery is upgraded to 3.7.1. - **django.contrib.auth** - The new asynchronous functions are now provided, using an a prefix: django.contrib.auth.aauthenticate(), aget_user(), alogin(), alogout(), and aupdate_session_auth_hash(). - **Asynchronous views** - Under ASGI, http.disconnect events are now handled. This allows views to perform any necessary cleanup if a client disconnects before the response is generated. --- ## ✅ In Summary Django is a high-level Python web framework that simplifies and accelerates web development by providing a robust set of tools, libraries, and conventions. It emphasizes rapid development, clean and pragmatic design, and follows the "Don't Repeat Yourself" (DRY) principle. **Since its first release in 2003**, Django has been continuously improved by a super-active community where all the new features are discussed, voted, implemented, and later released. Today, Django continues to be a widely used and respected web framework, with an active community of developers and a rich ecosystem of packages and extensions. --- ## ✅ Resources - 👉 Access [AppSeed](https://appseed.us/) and start your next project - 👉 [Deploy Projects on Aws, Azure, and DO](https://www.docs.deploypro.dev/) via **DeployPRO** - 👉 Create landing pages with [Simpllo, an open-source site builder](https://www.simpllo.com/) - 👉 [Django App Generator](https://app-generator.dev/django/) - A 2nd generation App Builder
