how to change date time format in admin panel?

[Mahdikhaloei]

Hi, I added two field in my model:
created_at = jmodels.jDateTimeField(auto_now_add=True, null=True, blank=True)
updated_at = jmodels.jDateTimeField(auto_now=True, null=True, blank=True)

But the display of these fields in django admin panel is not in the format I want:
1401-12-01 19:31:18.118063+0330

Hi, What is your Django and Django-Jalali version?

Where do you check the fields in the admin panel? on the object view page?
What format do you expect to get?

[Mahdikhaloei]

django-jalali == 6.0.1
django == 4.1.7

in the admin.py:
@admin.register(ProductBasedOnTime)
class ProductBasedOnTimeAdmin(admin.ModelAdmin):
fields = ( "created_at", "updated_at")
readonly_fields = ("created_at", "updated_at")

my expected format:
'%H:%M:%S _ %y/%m/%d'

thanks.

Django DateTimeField follow the format defined in DATETIME_FORMAT. So, by changing this setting, the format of datetime displayed in the admin listview and changeview will change.

But unfortunately, Django-jalali doesn't follow this setting. So, you can add a method and decorate it with admin.display to change the listview of jmodels.JDateTimeField.

@admin.register(ProductBasedOnTime)
class ProductBasedOnTimeAdmin(admin.ModelAdmin):
    fields = ( "formatted_created_at", "updated_at")
    readonly_fields = ("formatted_created_at", "updated_at")

    @admin.display(description='Created At')
        def formatted_created_at(self, obj):
            return obj.created_at.strftime("%H:%M:%S _ %y/%m/%d")

BTW, we need to change django-jalali to follow the format defined in DATETIME_FORMAT
