Re: DateTimeField(auto_now_add=True) and admin page

Readonly doesn't offer flexibility at all sadly. @ DC,i have been experiencing the same problem,but funny thing is other projects prior to this one displayed DateTimeField() on the admin just fine.

Hello Amit,

Yes, this is solution - I wanted those fields to be shown in admin, I
understand they're read-only. So, I put this in EcoPointAdmin and it
works:

readonly_fields = ['entry_date', 'last_change_date']

Thank you.
