A Trait for a Model

Required Associated Types

type Entity: EntityTrait

Required Methods

fn get(&self, c: <Self::Entity as EntityTrait>::Column) -> Value

Get the Value of a column from an Entity

fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value)

Set the Value of a column in an Entity

Provided Methods

fn find_related<R>(&self, _: R) -> Select<R>

where R: EntityTrait, Self::Entity: Related<R>,

Find related Models

fn find_linked<L>(&self, l: L) -> Select<<L as Linked>::ToEntity>

where L: Linked<FromEntity = Self::Entity>,

Find linked Models

fn delete<'a, 'async_trait, A, C>( self, db: &'a C, ) -> Pin<Box<dyn Future<Output = Result<DeleteResult, DbErr>> + Send + 'async_trait>>

where 'a: 'async_trait, Self: IntoActiveModel<A> + 'async_trait, C: ConnectionTrait + 'async_trait, A: ActiveModelTrait<Entity = Self::Entity> + ActiveModelBehavior + Send + 'a + 'async_trait,

Delete a model

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.

Implementations on Foreign Types

impl ModelTrait for Model

type Entity = Entity

fn get( &self, c: <<Model as ModelTrait>::Entity as EntityTrait>::Column, ) -> Value

fn set( &mut self, c: <<Model as ModelTrait>::Entity as EntityTrait>::Column, v: Value, )
