Expand description

The interface for Model, implemented by data structs

Required Associated Types§

Source

type Entity: EntityTrait

Required Methods§

Source

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

Get the Value of a column from a Model

Source

fn get_value_type(c: <Self::Entity as EntityTrait>::Column) -> ArrayType

Get the Value Type of a column from the Model

Source

fn try_set( &mut self, c: <Self::Entity as EntityTrait>::Column, v: Value, ) -> Result<(), DbErr>

Set the Value of a Model field, return error if failed

Provided Methods§

Source

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

Set the Value of a Model field, panic if failed

Find related Models belonging to self

Source

fn find_linked<L>(&self, l: L) -> Select<<L as Linked>::ToEntity>
where L: Linked<FromEntity = Self::Entity>,

Find linked Models belonging to self

Source

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

Source

fn get_primary_key_value(&self) -> ValueTuple

Get the primary key value of the 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.
