Derive macro for inserting struct into sql.
Instead of manually creating insert query and binding all attributes:
let query = r#"
insert into article
( title, subtitle, url, text )
values
( $1, $2, $3, $4 )
returning *
"#;
let result: Article = sqlx::query_as::<_, Article>(query)
.bind(&article.title)
.bind(&article.subtitle)
.bind(&article.url)
.bind(&article.text)
.fetch_one(&mut conn)
.await?;
Using derive macro if simplifies to this:
let res = car.insert::<Car>(&pool, "cars").await?
#[derive(Default, Debug, std::cmp::PartialEq, sqlx::FromRow)]
struct Car {
pub id: i32,
pub name: String,
pub color: Option<String>
}
#[derive(Default, Debug, sqlx::FromRow, sqlxinsert::PgInsert)]
struct CreateCar {
pub name: String,
pub color: Option<String>,
}
impl CreateCar {
pub fn new<T: Into<String>>(name: T) -> Self {
CreateCar {
name: name.into(),
color: None,
}
}
}
#[tokio::main]
async fn main() -> eyre::Result<()>{
let url = "postgres://user:pass@localhost:5432/test_db";
let pool = sqlx::postgres::PgPoolOptions::new().connect(&url).await.unwrap();
let car_skoda = CreateCar::new("Skoda");
let res: Car = car_skoda.insert::<Car>(pool, "cars").await?;
Ok(())
