Django 5.0 Delight: Unraveling the Newest Features
Hello everyone! As 2023 draws to a close, our reasons for celebration extend well beyond the upcoming holidays and vacation. Exciting developments await in the technology realm, including the unveiling of Python 3.12 and the much-anticipated Django 5.0.
This latest release of our Python-based web framework (still the most popular option on the market) signifies a noteworthy advancement that is bound to excite Django enthusiasts everywhere.
204 individuals, in addition to numerous unsung heroes, dedicated their time and efforts to contribute to the launch of Django 5.0. Thanks to each and every one of you! 🙂
Now, let’s explore the remarkable features integrated into this version.
Default values
Django introduced the Field.db_default parameter, making it possible to have database-computed default values for model fields. This functionality enables you to specify default values that are database-computed.
Generated fields
The new GeneratedField enables developers to establish database-generated columns within Django models. This field has the ability to calculate its value by leveraging other fields in the model and is applicable across all supported database backends for establishing a field that is consistently computed based on other fields.
In the following illustration, we will concatenate a country code onto a phone number, storing the result in the phone_number_with_ext column.
Facet filters
Facet counts will be displayed for active filters in the admin change list when activated through the UI toggle. This functionality can be modified using the newly introduced ModelAdmin.show_facets attribute.
Form field
Django 5.0 introduces the concept of a field group along with field group templates, streamlining the rendering of various components associated with a Django form field, including its label, widget, help text, and errors.
The below example is taken from the official documentation.
This is a much more simplified version.
AsyncClient
Django 5.0 introduces additional asynchronous methods to both the Client and AsyncClient, enabling asynchronous testing of Django applications. This enhancement enables you to create tests that more faithfully replicate the asynchronous behavior of the application.
