Allow empty datetime fields in APIToken model admin.
Review Request #12526 — Created Aug. 10, 2022 and submitted — Latest diff uploaded
APITokenmodel includes several datetime fields which are allowed
to be blank (such as invalidation or expiration). However, the
definitions of these fields were missing
blank=True, which meant that
the auto-generated form used in the admin site showed these fields as
required. This change fixes that.
Was able to save an APIToken with these fields as blank.
