Trait AutoRouteBinding 

pub trait AutoRouteBinding: Sized + Send {
    // Required method
    fn from_route_param<'life0, 'async_trait>(
        value: &'life0 str,
    ) -> Pin<Box<dyn Future<Output = Result<Self, FrameworkError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait for automatic route model binding

This trait is automatically implemented for all SeaORM models whose Entity implements ferro_rs::database::Model. You don’t need to implement this manually.

Unlike RouteBinding, this trait doesn’t require a param_name() method. The parameter name is derived from the handler function signature.

Example

// Just use Model in handler - binding is automatic!
#[handler]
pub async fn show(user: user::Model) -> Response {
    json_response!({ "name": user.name })
}

Required Methods

fn from_route_param<'life0, 'async_trait>( value: &'life0 str, ) -> Pin<Box<dyn Future<Output = Result<Self, FrameworkError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Fetch the model from the database using the route parameter value

This method parses the parameter as the primary key type and fetches the corresponding model from the database.

Returns

• Ok(Self) - The model was found
• Err(FrameworkError::ModelNotFound) - Model not found (returns 404)
• Err(FrameworkError::ParamParse) - Parameter could not be parsed (returns 400)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<M, E> AutoRouteBinding for M

where M: SeaModelTrait<Entity = E> + Send + Sync, E: EntityTrait<Model = M> + Model + Sync, E::PrimaryKey: PrimaryKeyTrait, <E::PrimaryKey as PrimaryKeyTrait>::ValueType: FromStr + Send,

Blanket implementation of AutoRouteBinding for all SeaORM models

This automatically implements route model binding for any SeaORM Model type whose Entity implements ferro_rs::database::Model. Supports any primary key type that implements FromStr (i32, i64, String, UUID, etc.).
