模型的创建方式及简单使用

model的创建

可以使用artisan命令创建，默认在于 app/Http 平级的下面

  1. php artisan make:model Article

数据库连接

laravel默认使用model名称小写+s去数据库里面找相同名字的表

查询主键

findOrFail(1) ，查询主键为1的记录，laravel默认主键名为id

  1. $res = \App\Article::findOrFail(1);

直接拿出表里面的数据

  1.  public function show()
  2.     {
  3.         echo '<pre>';
  4.         $res = \App\Article::findOrFail(1)->toArray();
  5.         print_r($res);
  6.     }

指定表名

在model类中指定

  1. class Article extends Model
  2. {
  3.     protected $table = 'article';
  4. }

指定id

在model类中指定

  1. class Article extends Model
  2. {
  3.     protected $table = 'article';
  4.     protected $primaryKey = 'aid';
  5. }

调用model中的方法

  1. lass Article extends Model
  2. {
  3.     protected $table = 'article';
  4. //    protected  $primaryKey = 'aid';
  5.     public function bbb(){
  6.         $data = $this->findOrFail(1)->toArray();
  7.         return $data;
  8.     }
  9. }
  1. class Home extends Controller
  2. {
  4.     public function show(Article $aaa)
  5.     {
  6.         echo '<pre>';
  7. //        $res = \App\Article::findOrFail(1)->toArray();
  8.         $res = $aaa->bbb();
  9.         print_r($res);
  10.     }
  11. }

视图

view的创建

只能手动创建，可以在views下建立文件夹，比如home文件夹，里面有lists.blade.php，访问就必须带上文件夹名字 return view('home.lists'); 来指定访问此视图

返回数据给view

  1. public function lists(){
  2.         $res = \App\Article::findOrFail(1)->toArray();
  3.         print_r($res['money']);
  4.         return view('home.lists',['order'=>$res]);
  5.     }
  1. <p>金额：{{$order['money']}}</p>

CSRF

在post请求时需要csrf，get请求不需要。
在页面任何地方写个@csrf，报错419
405，get/post方式错误

  1. <!DOCTYPE html>
  2. <html>
  3. <head>
  4.     <title></title>
  5.     <script type="text/javascript" src="/js/jquery.min.js"></script>
  6. </head>
  7. <body>
  8. <div>用户名：<input type="text" name="username"></div>
  9. <div>密码：<input type="password" name="pwd"></div>
  10. <div>重复密码：<input type="password" name="repwd"></div>
  11. <button type="button" onclick="doreg()">注册</button>
  12. @csrf
  14. <script type="text/javascript">
  15.     function doreg() {
  16.         var username = $.trim($('input[name="username"]').val());
  17.         var pwd = $.trim($('input[name="pwd"]').val());
  18.         var repwd = $.trim($('input[name="repwd"]').val());
  19.         if (username == '') {
  20.             return alert('请输入用户名');
  21.         }
  22.         $.post('/account/savereg', {
  23.             username: username,
  24.             pwd: pwd,
  25.             _token: $('input[name="_token"]').val()
  26.         }, function (res) {
  27.             alert(res.msg);
  28.             if (res.code == 0) {
  29.                 window.location.href = '/';
  30.             }
  31.         }, 'json');
  32.     }
  33. </script>
  34. </body>
  35. </html>

Teacher's comments：作业看上去非常的整洁, 舒服 , 看来你对markdown语法的运用很熟悉了, laravel是一个最流行的框架, 如果你打算做web开发, 并选择php做为快速开发语言的话, laravel是必须要掌握的
