BlameableBehavior

Struct BlameableBehavior 

Source
pub struct BlameableBehavior {
    pub created_field: &'static str,
    pub updated_field: &'static str,
}
Expand description

自动填充操作人 Behavior

§示例

use sz_orm_model::behaviors::{Behavior, BlameableBehavior};
use sz_orm_model::hooks::HookContext;
use sz_orm_model::Value;
use std::collections::HashMap;

let b = BlameableBehavior::new("created_by", "updated_by");
let ctx = HookContext::default().with_operator(42);
let mut attrs = HashMap::new();
b.before_insert(&ctx, &mut attrs).unwrap();
assert_eq!(attrs.get("created_by"), Some(&Value::I64(42)));
assert_eq!(attrs.get("updated_by"), Some(&Value::I64(42)));

Fields§

§created_field: &'static str

创建人字段名(默认 “created_by”)

§updated_field: &'static str

更新人字段名(默认 “updated_by”)

Implementations§

Source§

Source

pub fn new(created_field: &'static str, updated_field: &'static str) -> Self

创建 BlameableBehavior

Source

pub fn default_fields() -> Self

使用默认字段名(created_by/updated_by)
