A simple library that establishes a connection and sets/creates the namespace&db and sets the types of the attributes
Example
pub async fn establish(path: PathBuf) -> surrealdb::Result<Surreal<Db>> {
let conn = Surreal::new::<SpeeDb>((path.join("db"), Config::default().strict()));
surrealdb_extras::use_ns_db(conn, "test", "test", vec![Test::register]).await
}
#[derive(surrealdb_extras::SurrealTableEntry, Deserialize, Serialize, Clone, Default)]
#[db("test_table")]
#[sql(["DEFINE EVENT test_table_updated ON TABLE test_table WHEN $event = \"UPDATE\" AND $before.updated == $after.updated THEN (UPDATE $after.id SET updated = time::now() );"])]
struct Test {
random_number: i32,
/// renamed field
#[opt(rename = "new_name")]
#[serde(rename = "new_name")]
data: String,
/// overwrites the detected db type
#[opt(db_type = "string")]
data: CustomStructWithSerialize,
/// will be excluded in get_or_insert check
#[opt(exclude = true)]
updated: Datetime
}
pub async fn demo() {
let conn = establish(PathBuf::new()).await.unwrap();
let test = Test::default();
// creates new item with custom id and return self
let _: Option<Test> = test
.clone()
.insert(&conn, Some(sql::Id::rand()))
.await
.unwrap();
// creates new item with random id and return record
let v: surrealdb_extras::Record = test.add(&conn).await.unwrap().unwrap();
// delete record
let v: Option<surrealdb_extras::Record> = v.delete(&conn).await.unwrap();
