Expose / Exclude based on its ‘parent’ relationship in One to Many

[hsb1007]

@geotas thank you for your quick response but i believe it is still not answered fully

I have a social Post / Comment entity and its User entity (creator of the post) in OneToMany relation ship.

Depending on the Post privacy setting, I want to control what user detail gets return.

I have checked

Exclude/Expose with if expression but could not access to its parent entity in relation (Post / Comment)

Preserialize Event - For some reason, it doesn't event get called at the moment and unsure whether I can set 'Dynamic' Groups for User entity on 'Preserialize' event.

Custom Exclusion Policy - Still unsure how I can access to Post / Comment from User

Does anyone have any idea?

I am serialising ‘Post’ and user needs to have different fields return. In its Exclude and Expose, i dont get to reference to the specific Post i am serialising if it makes sense.

I cannot do things like getPost from user as user has many Posts..

I am scratching my head for hours..
