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".

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.).
