Crate co_orm 

Derive macro for sqlx to implement Create, Read, Update, and Delete (CRUD) methods.

Use

adding the following to your project’s Cargo.toml:

[dependencies]
co-orm = { virsion = "0.3", features = ["mysql"] }
sqlx = { version = "0.8", features = ["mysql"] }

features: mysql, postgres, sqlite, mssql

Examples

use co_orm::{Crud, args};

#[derive(Debug, Crud, sqlx::FromRow)]
#[co_orm(rename = "users")] // rename table name
pub struct User {
    // #[co_orm(id)] // default first field is primary key
    #[co_orm(skip_insert)] // insert will ignore this field
    pub id: i64,
    #[co_orm(rename = "name")] // rename field name
    pub name: String,
    #[co_orm(update)] // generate method update_xxx.
    pub password: String,
    #[co_orm(skip)] // ignore field
    #[sqlx(skip)]
    pub addr: Option<String>,
    #[co_orm(skip_insert)] // insert will skip this field.
    pub update_at: Option<NaiveDateTime>,
}

// use crud
let u = User::get(&pool, 1).await;
println!("get {:?}", u);
let u = User::get_by(&pool, "where id=?", args!(1)).await;
println!("get_by {:?}", u);
let u = User::query_where(&pool, Where::new().eq("name", "jack")).await;
println!("query_where {:?}", u);
let u = User::query_page_where(&pool, Where::new().eq("name", "jack"), 1, 10).await;
println!("query_page_where {:?}", u);
let u = User::update_where(&pool, Where::new().eq("name", "jack")).await;
println!("update_where {:?}", u);
let u = User::delete_where(&pool, Where::new().eq("name", "jack")).await;
println!("delete_where {:?}", u);
