The reason why your overridden get_status_display method is not being applied in the Django admin is because the admin's display_for_field function uses the flatchoices attribute of the field to retrieve the display value of the field's current value.
The flatchoices attribute is a list of two-tuples that represent the choices available for the field, flattened into a single list. The first element of each tuple is the value, and the second element is the display string. The display_for_field function uses the flatchoices list to retrieve the display value of the current value, rather than calling the field's get_FOO_display method. To make use of your overridden get_status_display method in the admin, you can set the flatchoices attribute of the field to None or remove the attribute altogether. This will cause the admin to call the get_status_display method instead of the display_for_field function. class MyModelAdmin(admin.ModelAdmin): form = MyModelForm class MyModelForm(forms.ModelForm): class Meta: model = MyModel fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # Remove the flatchoices attribute of the status field self.fields['status'].flatchoices = None In this example, we're creating a MyModelForm that is used in the MyModelAdmin. We're overriding the __init__ method of the form to remove the flatchoices attribute of the status field, which will cause the admin to call the get_status_display method instead.
