Lazy loading of bytea/text

[owochle]

Hello,
I'm storing files in my database which are quite small, but when i query 50+ entries, it starts to pile up. Would there be a way in SeaORM to have a lazy loaded Vec or a way to mark fields as "lazy" which would generate getter methods ?

struct Model {
    #[lazy]
    file: Vec<u8>
}

// ----

fn main() {
    let model: Model
    model.get_file().await // Vec<u8> or &[u8]
}

For now, I am using custom models, selecting all columns but file, but it makes this more cumbersome

Could be a feature.
I just want to put on the table that implementing something like Django's defer() instead of #[sea_orm(lazy)] would be more practical. defer() allows to specify columns we don't want fetch, basically the opposite of Django's only() and SeaORM's select_only()

Side note: if you have control over the schema, storing files on disk/object storage and keeping only a path/URL in the DB is recommended.

I feel like although defer() is a good idea, it does not really aims at the same thing. Marking a field as lazy would make you able to use Model as usual, without needing some custom models and into_model calls, whereas defer would required something like this.
