Struct SelectTwoMany

pub struct SelectTwoMany<E, F>
where
    E: EntityTrait,
    F: EntityTrait,
{ /* private fields */ }

Defines a structure to perform a SELECT operation on many Models

Implementations

impl<E, F> SelectTwoMany<E, F>

where E: EntityTrait, F: EntityTrait,

pub fn into_json(self) -> Selector<SelectTwoModel<JsonValue, JsonValue>>

Convert the results to JSON

pub async fn stream<'a: 'b, 'b, C>( self, db: &'a C, ) -> Result<impl Stream<Item = Result<(E::Model, Option<F::Model>), DbErr>> + 'b + Send, DbErr>

where C: ConnectionTrait + StreamTrait + Send,

Stream the result of the operation

pub async fn stream_partial_model<'a: 'b, 'b, C, M, N>( self, db: &'a C, ) -> Result<impl Stream<Item = Result<(M, Option<N>), DbErr>> + 'b + Send, DbErr>

where C: ConnectionTrait + StreamTrait + Send, M: PartialModelTrait + Send + 'b, N: PartialModelTrait + Send + 'b,

Stream the result of the operation with PartialModel

pub async fn all<'a, C>( self, db: &C, ) -> Result<Vec<(E::Model, Vec<F::Model>)>, DbErr>

where C: ConnectionTrait,

Get all Models from the select operation

SelectTwoMany::one() method has been dropped (#486)

You can get (Entity, Vec<relatedEntity>) by first querying a single model from Entity, then use ModelTrait::find_related on the model.

See https://www.sea-ql.org/SeaORM/docs/basic-crud/select#lazy-loading for details.
