DataObject operations that require a live database connection.

Provided Methods

fn get(conn: &impl ConnectionMethods, id: impl ToSql) -> Result<Self, Error>

where Self: Sized + DataObject, Self::PKType: Sync,

Find this object in the database based on primary key. Returns Error::NoSuchObject if the primary key does not exist.

fn try_get( conn: &impl ConnectionMethods, id: impl ToSql, ) -> Result<Option<Self>, Error>

where Self: Sized + DataObject,

Find this object in the database based on primary key. Returns None if the primary key does not exist.

fn save(&mut self, conn: &impl ConnectionMethods) -> Result<(), Error>

where Self: DataObject,

Save the object to the database, handling both inserts and updates.

If the object has an AutoPk that is uninitialized, save will always perform an insert. If the AutoPk is initialized or there is no AutoPk, save will perform an upsert (insert or replace). After saving the main object, many-to-many relationships it holds are also saved.

fn delete(&self, conn: &impl ConnectionMethods) -> Result<(), Error>

where Self: DataObject,

Delete the object from the database.
