type Where = {
    [key: string]: WhereField | Where[];
    or?: Where[];
    and?: Where[];
}

{
  "hero": [{
    "type" : { "equals": "basic"}
  }] 
}

{
  "hero.type": { "equals": "basic"}
 
}

  You need to use the dot notation version

  Yes, I know. But I'm trying to create a type safe query builder for my payload-rbac library, so I'm trying to understand the type definition. the type definition specifies that I can use

  { [key: string}: Where[] }

  .What does this mean?

  
  
  

  If this is just to satisfy the type system to support the

  or

  and

  and

  property, then I can ignore it. But if it has some meaning, than I can't.

  Got it. Yes it is just for and/or

  This is what I've got so far:

  
  
  

  import { WhereField } from 'payload/types';
  
  type ValueOf<T extends object> = T[keyof T];
  type AllKeys<T> = T extends object ? (keyof T & string) | ValueOf<{ [K in keyof T & string]: `${K}.${AllKeys<T[K]>}` }> : never;
  
  export type Where<T extends object = any> = Record<AllKeys<T>, WhereField> & {
    or?: Where<T>[];
    and?: Where<T>[];
  };

  
  
  

  But that doesn't take the

  [key: string]: Where[]

  into account.

  
  
  

  Thanks
