mysql - Active record do not send created at and updated at -

we have table columns: created_at datetime not null default current_timestamp, updated_at datetime not null default current_timestamp on update current_timestamp,

when updating active record insert query contains created_at , updated_at columns.

even after setting config.active_record.record_timestamps = false active record sending created_at , updated_at null.

is there way not send these columns @ want handle @ mysql level.

as far mysql concerned, updated_on columns should per below auto update-

updated_at timestamp not null default current_timestamp on update current_timestamp
