I am creating table with sqlalchemy.

user = Table('users', Metadata,
Column('datecreated', TIMESTAMP,                                  
            server_default=text('CURRENT_TIMESTAMP')),            
Column('datemodified', TIMESTAMP,                                 
               server_onupdate=text('CURRENT_TIMESTAMP')),
)

But this will not set DEFAULT ON UPDATE CURRENT_TIMESTAMP.

I checked out How do you get SQLAlchemy to override MySQL "on update CURRENT_TIMESTAMP" but that will for literal I need to wire that in create table definition.

This worked on Mysql 8

sa.Column('created_at', sa.TIMESTAMP, server_default=func.now()),
sa.Column('updated_at', sa.TIMESTAMP, server_default=text('CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP'))

For some reason the server_onupdate options was not working.
