php - Symfony Not able to save manyToOne bidirectional Entity -

i have entity called survey , have entity called creditcards

creditcard linked survey using manytoone

survey linked creditcard using onetomany

the survey has bunch of financial related questions gets saved in survey table , asks user creditcard related details gets saved in creditcard table, since user can have more 1 card can add multiple card details , manytoone , onetomany comes play.

i have gone through step step through this article cant save work, when try save error get

a new entity found through relationship 'examplebundle\entity\survey#creditcards' not configured cascade persist operations entity: examplebundle\entity\creditcards@000000001bbd76da000000008bbf1e28. solve issue: either explicitly call entitymanager#persist() on unknown entity or configure cascade persist association in mapping example @manytoone(..,cascade={"persist"}). if cannot find out entity causes problem implement 'examplebundle\entity\creditcards#__tostring()' clue. 500 internal server error - orminvalidargumentexception 

the article refereed above talk @ this section, followed instruction , no matter cant passed error. on 6 hours trying solve , cant think straight more.

i appreciate if can here on this.

you'll need add cascade: ["persist"] onetomany mapping in survey yaml.

and way: class names should singular , capitalized.
