How to make the Record id as a string instead of Thing

[mimib00]

I have a struct called User and the field ID has a type of Thing but when it gets serialized with Serde it returns a map but I want it to produce just a string of the record like this "users:ozsjoklahslakjssjxo"

I needed to do that for an async-graphql server, knowing that this obviously has downsides, in the sense that I'm limiting myself to use string id's only... anyway, for now I just needed that.

use serde::{Deserialize, Deserializer};
use surrealdb::sql::Thing;

fn thing_to_string<'de, D>(deserializer: D) -> Result<Option<String>, D::Error>
where
    D: Deserializer<'de>,
{
    let t = Thing::deserialize(deserializer)?;
    Ok(Some(t.to_raw()))
}


#[derive(Deserialize, Serialize)]
pub struct Foo {
    #[serde(deserialize_with = "thing_to_string")]
    id: Option<String>,
    ...
}

Hope that helps

Thanks, I'll test this solution.

thy @skriems, I had to slightly change it, but it worked very well:

fn thing_to_string<'de, D>(deserializer: D) -> Result<String, D::Error>
    where
        D: Deserializer<'de>,
{
    let t = Thing::deserialize(deserializer)?;
    Ok(t.to_raw())
}
