Update

Update One

You will get a Model from find result. If you want to save the model back into the database, you need to convert it into an ActiveModel first. The generated query will only include the Set attributes.

let pear: Option<fruit::Model> = Fruit::find_by_id(28).one(db).await?;

// Into ActiveModel
let mut pear: fruit::ActiveModel = pear.unwrap().into();

// Update name attribute
pear.name = Set("Sweet pear".to_owned());

// SQL: `UPDATE "fruit" SET "name" = 'Sweet pear' WHERE "id" = 28`
let pear: fruit::Model = pear.update(db).await?;

To update all attributes, you can convert Unchanged into Set.

// Into ActiveModel
let mut pear: fruit::ActiveModel = pear.into();

// Update name attribute
pear.name = Set("Sweet pear".to_owned());

// Set a specific attribute as "dirty" (force update)
pear.reset(fruit::Column::CakeId);
// Or, set all attributes as "dirty" (force update)
pear.reset_all();

// SQL: `UPDATE "fruit" SET "name" = 'Sweet pear', "cake_id" = 10 WHERE "id" = 28`
let pear: fruit::Model = pear.update(db).await?;

Update Many

You can also update multiple rows in the database without finding each Model with SeaORM select.

// Bulk set attributes using ActiveModel
let update_result: UpdateResult = Fruit::update_many()
.set(pear)
.filter(fruit::Column::Id.eq(1))
.exec(db)
.await?;

// UPDATE `fruit` SET `cake_id` = 1 WHERE `fruit`.`name` LIKE '%Apple%'
Fruit::update_many()
.col_expr(fruit::Column::CakeId, Expr::value(1))
.filter(fruit::Column::Name.contains("Apple"))
.exec(db)
.await?;
