Derive Macro Factory 

#[derive(Factory)]

Available on crate feature macros and (crate features model-mysql or model-postgres or model-sqlite) only.

Derive rust_web_server::test_client::factory::Factory for a #[derive(Model)] struct, and an inherent T::factory() returning a ModelFactory<T> for tests (17.30.0).

Each field gets its type’s FactoryValue default (numbers 0, bool false, Option None, a String the field’s name plus a sequence number), or Default::default() for a type without one and for #[ignore] fields. The #[primary_key] is 0 when it’s auto_increment, else the sequence number. It reads the same attributes as #[derive(Model)] and declares none of its own.

#[derive(rust_web_server::Model, rust_web_server::Factory, Debug, Clone)]
#[table(name = "users")]
pub struct User {
    #[primary_key(auto_increment)]
    pub id: i64,
    pub name: String,
}

let user = User::factory().with(|u| u.name = "Ann".into()).create(&pool).await?;
