use geekorm::{Table, PrimaryKeyInteger};
use geekorm::prelude::*;

#[derive(Table)]
struct Users {
    id: PrimaryKeyInteger,
    name: String,
    age: i32,
    occupation: String,
    country: Option<String>,
}

let user = Users::new(
    String::from("geekmasher"),
    42,
    String::from("Software Developer")
);

功能 - 生成的辅助方法

当启用 helpers 功能时，为结构体生成以下辅助方法

注意： 这是一个非常实验性的功能，可能会在未来更改。

use geekorm::{Table, PrimaryKeyInteger};
use geekorm::prelude::*;

#[derive(Table)]
struct Users {
    id: PrimaryKeyInteger,
    name: String,
    age: i32,
    occupation: String,
}

// Select by column helper function
let user = Users::query_select_by_name("geekmasher");
# assert_eq!(user.query, String::from("SELECT id, name, age, occupation FROM Users WHERE name = ?;"));
let user = Users::query_select_by_age(42);
# assert_eq!(user.query, String::from("SELECT id, name, age, occupation FROM Users WHERE age = ?;"));
let user = Users::query_select_by_occupation("Software Developer");
# assert_eq!(user.query, String::from("SELECT id, name, age, occupation FROM Users WHERE occupation = ?;"));

功能 - 为列生成随机数据

当使用 rand 功能时，可以自动生成随机字符串并使用

# #[cfg(feature = "rand")]
# {
use geekorm::prelude::*;
use geekorm::{Table, PrimaryKeyInteger};

#[derive(Table, Debug)]
pub struct Users {
    id: PrimaryKeyInteger,
    name: String,
    #[geekorm(rand, rand_length = 42, rand_prefix = "token")]
    token: String
}

let mut user = Users::new(String::from("geekmasher"));
println!("{}", user.token);
# assert_eq!(user.token.len(), 48);

# let old_token = user.token.clone();
user.regenerate_token();
# assert_ne!(old_token, user.token);
# }

rand 属性

• rand：将字符串字段设置为随机生成的值
• rand_length：设置随机生成字符串的长度
  • 默认：32
• rand_prefix：为随机生成的字符串设置前缀
  • 默认值：无

特性 - 为存储密码生成哈希值

使用 hash 特性时，您可以自动对密码进行哈希处理，以确保它们被安全存储。

# #[cfg(feature = "hash-sha512")]
# {
use geekorm::prelude::*;
use geekorm::{Table, PrimaryKeyInteger};

#[derive(Table, Debug)]
pub struct Users {
    id: PrimaryKeyInteger,
    username: String,

    #[geekorm(hash)]
#   // This config below is not the most secure algorithm, always use default ;) 
#   #[geekorm(hash_algorithm = "Sha512")]
    password: String,
}

# fn main() -> Result<(), geekorm::Error> {
let mut user = Users::new(String::from("geekmasher"), String::from("password"));
# assert_eq!(user.password.len(), 95);

// Update password
user.hash_password("newpassword");

// Verify password
if user.check_password("newpassword")? {
   println!("Password is correct");
} else {
   println!("Password is incorrect");
}

# Ok(())
# }
# }

hash 属性

• hash 或 password：将字符串字段设置为可哈希的值
• hash_algorithm：设置要使用的算法
  • 默认值：Pbkdf2
