Infer type for relational query

Thanks @Cayter So I do have that and I realise I poorly worded my question. I actually was wondering if there was something along the lines of drizzle infer type from a schema method but for relations querties. so say I have a post table I can do something like this

export type Post = InferModel<typeof post>;

export type Post = InferModel<typeof post>;

I now have the exact type for Post that I can use, in say props for a component. Is there a way I could get a type for what is inferred? @mcgrealife method actually worked as well where i just take the inferred return type. Did not see anything in the docs about it get an explicit type for what a relation query could return.

Infer type for relational query

You probably were doing this but for anyone else, the return type of the async func would be a union type of the type | undefined wrapped in a promise. So this is what I did to get the exact type:

export type CustomRelationType = NonNullable<
  Awaited<ReturnType<typeof getUserWithPostsAndComments>>
>;

export type CustomRelationType = NonNullable<
  Awaited<ReturnType<typeof getUserWithPostsAndComments>>
>;

@mcgrealife Is this what you also had to do? or did I just do some longer for no reason. 🤣
