/**  * @orm\manytomany(targetentity="event")  * @orm\jointable(name="viewed_events",  *      joincolumns={@orm\joincolumn(name="user_id", referencedcolumnname="id")},  *      inversejoincolumns={@orm\joincolumn(name="event_id", referencedcolumnname="id")}  *      )  **/ protected $viewedevents;

the problem when try delete event entity integrity constraint violation: 1451 cannot delete or update parent row: foreign key constraint fails error. how solve this? tried adding orphanremoval=true that: @orm\manytomany(targetentity="event", orphanremoval=true) , tried adding cascade="delete" , cascade="all" instead no success.

ondelete="cascade"
