thinkphp5.0初入模型，實例

user模型

<?php
namespace app\index\model;

use think\Model;

class User extends Model
{
    protected $pk = 'username';

//     protected $autoWriteTimestamp = true;
//     protected $autoWriteTimestamp = 'datetime';


    // 定義時間戳字段名
    protected $createTime = 'createat';
    protected $updateTime = 'updateat';
    // 關閉自動寫入update_time字段
//     protected $updateTime = false;

    //設置只讀字段
    protected $readonly = ['username','grade'];
    //類型轉換
    protected $type = [
        'createat'  =>  'datetime',
        'updateteat'  =>  'datetime',
    ];
        //獲取器
    public function getGradeAttr($value)
    {
        $grade = [1=>'超級管理員',2=>'普通管理員',3=>'普通用戶'];
        return $grade[$value];
    }

    //自動完成
//     protected $auto = ['username', 'ip'];
//     protected $insert = ['status' => 1];
//     protected $update = [];

//     protected function setNameAttr($value)
//     {
//         return strtolower($value);
//     }

//     protected function setIpAttr()
//     {
//         return request()->ip();
//     }

}

驗證器user

<?php
namespace app\index\validate;

use think\Validate;

class User extends Validate
{
    protected $rule = [
        'name'  =>  'require|min:25',
        'email' =>  'email',
    ];
}

?>

使用時候

<?php
namespace app\index\controller;

use think\Db;
use think\Controller;
use app\index\model\User;

class Index extends Controller
{

public function index()
{
// $data = [
// 'name'=>'thinkphp',
// 'email'=>'thinkphpqq.com'
// ];

// $validate = validate('User');
// if(!$validate->check($data)){
// dump($validate->getError());
// }
$data = Db::view('word', 'wordId,wordEn,wordCh')->view('cf', 'cfName', 'word.wordCfId=cf.cfId', 'LEFT')->select();

// dump(cache('user'));
// 實例化User模型

// 根據表單提交的POST數據創建數據對象
// $data['name'] = 'ThinkPHP';
// $data['email'] = '[e-mail]';

// $user = User::get('ys');
// $user->username = 'thinkphp';
// $user->grade = '6';
// $user->isLimit = '3';
// $user->save();

// $list = User::all();

$user = new User();
// $user->username='test';
// $user->grade=2;
// $map['username']='jkll';
// $user->save($map);
//查詢數據集
$list=$user
->limit(10)
->select();
// foreach ($list as $l){

// dump($l['updateat'].$l['username']);
// }
return json($list);

}
}
