django’s datetimefield works python datetime , date objects, has undocumented feature of being able automatically parse strings datetime objects. in datetimefield declaration, had

default=false

which neither datetime nor date. thus, django tries parse automatically you. failing so, emits cryptic message.

depending on specific need, should either replace, or remove default=false argument.
