Struct Update 

pub struct Update;

Type-level entry point for UPDATE builders, e.g. Update::one(model) and Update::many(Entity). You normally call EntityTrait::update / update_many instead.

Implementations

impl Update

pub fn one<E, A>(model: A) -> UpdateOne<A>

where E: EntityTrait, A: ActiveModelTrait<Entity = E>,

Update one ActiveModel

use sea_orm::{DbBackend, entity::*, query::*, tests_cfg::cake};

assert_eq!(
    Update::one(cake::ActiveModel {
        id: ActiveValue::set(1),
        name: ActiveValue::set("Apple Pie".to_owned()),
    })
    .validate()
    .unwrap()
    .build(DbBackend::Postgres)
    .to_string(),
    r#"UPDATE "cake" SET "name" = 'Apple Pie' WHERE "cake"."id" = 1"#,
);

pub fn many<E>(entity: E) -> UpdateMany<E>

where E: EntityTrait,

Update many ActiveModel

use sea_orm::{DbBackend, entity::*, query::*, sea_query::Expr, tests_cfg::fruit};

assert_eq!(
    Update::many(fruit::Entity)
        .col_expr(fruit::Column::Name, Expr::value("Golden Apple"))
        .filter(fruit::Column::Name.contains("Apple"))
        .build(DbBackend::Postgres)
        .to_string(),
    r#"UPDATE "fruit" SET "name" = 'Golden Apple' WHERE "fruit"."name" LIKE '%Apple%'"#,
);
