Additional Information

#[sea_orm(table_name = "categories")]
pub struct Model {

    pub api_key: Uuid,
    pub added: DateTime,
    pub updated: DateTime,
}

let db = &data.conn;
let  u = Uuid::parse_str(uuid.as_str()).expect("UUID is required!");
let category = Category::find()
        .filter(categories::Column::ApiKey.eq(u))
