CRUD

Create

let obj = _{モデル名}Factory {
    ...
}.create(conn);
_{モデル名}::save(conn, obj).await?;

Read

取得方法は多数ありますので、一例です。

let obj = _{モデル名}::find(&mut conn, id).await?

Update

更新時はカラム名のメソッドでアクセッサを呼び出し、set, add, sub, max, min, bit_and, bit_orを実行して更新します。

let mut obj = _{モデル名}::find_for_update(&mut conn, id).await?
obj.{カラム名}().set(1);
_{モデル名}::save(conn, obj).await?;

Delete

let obj = _{モデル名}::find_for_update(&mut conn, id).await?
_{モデル名}::delete(conn, obj).await?;

let obj = _{モデル名}::find_for_update(&mut conn, id).await?
_{モデル名}::force_delete(conn, obj).await?;
