symfony - How to save additional entity while persisting another in Doctrine? -


i've got place entity , distance one, so:

class place {     /** @orm\id @orm\column(type="integer") @orm\generatedvalue(strategy="auto") */     private $id;      /** @orm\column(type="string", length=62, nullable=false) */     private $name;      /** @orm\onetomany(targetentity="distance", mappedby="origin") */     protected $distancesto;      /** @orm\onetomany(targetentity="distance", mappedby="destination") */     protected $distancesfrom; }  class distance {     /** @orm\id @orm\column(type="integer") @orm\generatedvalue(strategy="auto") */     private $id;      /** @orm\manytoone(targetentity="place", inversedby="distancesto") */     protected $origin;      /** @orm\manytoone(targetentity="place", inversedby="distancesfrom") */     protected $destination;      /** @orm\column(type="integer") */     private $miles; }

i want every time new distance (from place_a place_b) saved, reverse distance (from place_b place_a) gets inserted in db. how can that?

you need create listener , listen persisting on distance entity. while persists can create new distance reverse route.
