Macro route_binding 

macro_rules! route_binding {
    ($entity:ty, $model:ty, $param:literal) => { ... };
}

Convenience macro to implement RouteBinding for a SeaORM model

DEPRECATED: This macro is no longer needed. Route model binding is now automatic for any model whose Entity implements kit::database::Model. Simply use the Model type in your handler parameter.

This macro implements the RouteBinding trait for a model, enabling automatic route model binding with 404 handling.

Arguments

• $entity - The SeaORM Entity type (e.g., user::Entity)
• $model - The SeaORM Model type (e.g., user::Model)
• $param - The route parameter name (e.g., "user")

Example

use kit::route_binding;

// In your model file (e.g., models/user.rs)
route_binding!(Entity, Model, "user");

// Now you can use automatic binding in handlers:
#[handler]
pub async fn show(user: user::Model) -> Response {
    json_response!({ "id": user.id, "name": user.name })
}

Route Definition

The parameter name must match your route definition:

routes! {
    get!("/users/{user}", controllers::user::show),
}
