在 Laravel 4 中使用 eloquent 进行简单插入

Question

我正在尝试将单个数据插入 Laravel 4 中的数据库，但尝试 3 小时后未能这样做。

下面是代码sn-p，

型号

用户.php

class User extends Eloquent
{
  protected $table='users';
  protected $protected = array();
}

迁移

class CreateUserInfoTable extends Migration {

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('users', function($table)
    {
        $table->increments('id');
        $table->string('name');
        $table->string('cntNo');
        $table->timestamps();
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::drop('users');
}

}

控制器

UserController.php

public function post_create()
{
    User::create(array('name'=>Input::get('name'),'cntNo'=>Input::get('cntno')));
}

Routes.php

Route::post('new/create', array('uses'=>'UserController@post_create'));

但我什至无法插入数据库。

在 app.php

中设置 debug => true 后的最新版本

Answer 1

请参阅Laravel docs for Mass Assignment。您只需将fillable 属性添加到您的模型：

protected $fillable = array('name', 'cntNo');

这将允许您在 create 方法中“批量分配”您的属性。

---

或者，您可以满足一个新的用户对象并单独设置它的值：

public function post_create()
{
    $user = new User;

    $user->name = Input::get('name');
    $user->cntNo = Input::get('cntno');

    $user->save();
}

Answer 2

参考： MassAssignmentException in Laravel

Laravel 默认提供针对批量分配安全问题的保护。这就是为什么您必须手动定义哪些字段可以“批量分配”

class User extends Eloquent
{
  protected $table='users';
  protected $guarded = array('id');
  protected $fillable = array('name', 'cntNo');
}
