A new Field.db_default
parameter in Django 5.0 allows developers to set database-computed default values. In addition, a GeneratedField
class enables creation of database-generated columns. This field can be used on all supported database back ends to build a field that is computed from other fields.
Django 5.0 offers more options for declaring field choices. Field.choices
for model fields and ChoiceField.choices
for form fields allow for more flexibility when declaring their values. Previously, choices
should be either a list of two-tuples or an enumeration types subclass, but the latter required accessing the .choices
attribute to provide values in the expected form.
