php - Delete polymorphic relation table automatically -

-

i have comments table can have 2 kinds of author, registered 1 , guest.

to handle that, made polymorphic relation between comments, user_registered, , guest table

when delete spesific post in posts table, comments have foreign key deleted problem guest , user_registered table have polymorphic relation comments table not automatically deleted.

so question is, can polymorphic relation table deleted automatically when main table deleted. foreign key behaviour (delete cascade)

thx guys..
