How to set validation conditions and default fields in redbeanphp in RESTful API mode?

I have a RESTful API project based on slim framework and redbeanphp ORM.
I can already implement API CRUD.
I’m having a problem now.
I cannot implement the default field settings and field validation of redbeanphp according to the redbeanphp documentation and stackoverflow posts.
