Question

我的默认注册表格出现SQLSTATE Integrity constraint violation错误。

我在新表中添加了排名行。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();
});

我希望服务器发送default的值，因此我将其添加到

\app\Services\Registrar.php;

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

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, felixinx@gmail.com, y$Rp6YFZivHDqVNsQLDzGar.dEqRf9vxdSdQd/H8.xNWvVLqS0gwpDe, 2015-04-18 15:07:23, 2015-04-18 15:07:23))"

为了保护您免受质量分配漏洞的影响，Laravel要求您通过create() - 方法传递它们，以明确设置（或排除）您希望成为mass assignable的值。

因此，如果您希望rank成为可批量分配的属性，则必须将其添加到用户的$fillable - 属性（这只是一个可指定质量的属性的数组）上-模型。任何其他不属于“白名单”的属性都将被忽略。所以在您的用户模型上，您只需：

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

您必须为要批量分配的每个模型类执行此操作。

专业提示： 您可以在架构中指定默认值，因此每次创建用户时都不必传递它们：

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

如果您在创建时未传递特定的“排名”，则会回退到“默认”。

另一个选项（您应谨慎使用）是使用forceCreate显式忽略质量分配约束：

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