Laravel：违反完整性约束

Laravel : Integrity constraint violation

提问by Félix Desjardins

I have a SQLSTATE Integrity constraint violationerror with the default register form.

我SQLSTATE Integrity constraint violation的默认注册表有误。

I have a add a rank row to a new table. Here's my migration;

我有一个向新表添加排名的行。这是我的迁移；

Schema::create('users', function(Blueprint $table)
{
    $table->increments('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->string('password', 60);
    $table->string('rank');
    $table->rememberToken();
    $table->timestamps();
});

I want that the server send the value of default, so I add this to

我希望服务器发送 的值default，所以我将其添加到

\app\Services\Registrar.php;

\app\Services\Registrar.php;

public function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
        'rank' => 'default',
    ]);
}

And I have the following error;

我有以下错误；

Illuminate\Database\QueryException thrown with message "SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: users.rank (SQL: insert into "users" ("name", "email", "password", "updated_at", "created_at") values (Félix Desjardins, [email protected], y$Rp6YFZivHDqVNsQLDzGar.dEqRf9vxdSdQd/H8.xNWvVLqS0gwpDe, 2015-04-18 15:07:23, 2015-04-18 15:07:23))"

In order to protect you from mass assignment vulnerabilities, Laravel requires you to explicitly set (or exclude) values you want to be mass assignableby passing them in through the create()-method.

为了保护您免受批量分配漏洞的影响，Laravel 要求您通过- 方法将它们传入，明确设置（或排除）您希望可批量分配的值create()。

So if you want rankto be a mass-assignable attribute, you have to add it to the $fillable-property (which is just an array of the mass-assignable attributes) on your User-model. Any other attribute that is not on the 'whitelist' so to speak will be ignored. So on your User model you just do:

因此，如果您想rank成为可批量分配的属性，则必须将其添加到$fillable用户模型上的-property（这只是可批量分配属性的数组）中。可以说不在“白名单”上的任何其他属性都将被忽略。因此，在您的 User 模型上，您只需执行以下操作：

protected $fillable = [
    'name',
    'email',
    'password',
    'rank',
];

You have to do this for every model-class you want to be mass-assignable.

您必须为每个想要批量分配的模型类执行此操作。

Pro-Tip:You can assign default values in your schema, so you don't have to pass them everytime you create a user:

专业提示：您可以在架构中分配默认值，因此您不必每次创建用户时都传递它们：

$table->string('rank')->default('default');

If you don't pass a specific 'rank' while creating, it will fall back to 'default'.

如果您在创建时没有通过特定的“等级”，它将回退到“默认”。

Another option (which you should use with caution) is to explicitly ignore the mass assignment constraints by using forceCreate:

另一个选项（您应该谨慎使用）是使用以下命令显式忽略质量分配约束forceCreate：

User::forceCreate([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
        'rank' => 'default',
    ]);
