使用 UUID 将权限分配给 spatie/laravel-permission 中的角色时出现非法偏移类型

Illegal offset type when assigning Permission into Role in spatie/laravel-permission using UUID

我已经实现 laravel-permission 使用 UUID 主键自定义我的模型。然后我创建了一个播种机:

$viewemployee = Permission::create(['id' => Str::uuid(), 'name' => 'view employee']);
$A = Role::create(['id' => Str::uuid(), 'name' => 'A']);

但是,当我尝试使用以下方式将权限分配给角色时:

$A->givePermissionTo($viewemployee);

当我运行种子

时,它显示这样的错误

ErrorException Illegal offset type at vendor/laravel/framework/src/Illuminate/Database/Eloquent/Relations/Concerns/InteractsWithPivot>Table.php:139

然后,我尝试了另一种方法来赋值:

$viewemployee->assignRole($A);

但是,它显示另一个错误:

Illuminate\Database\QueryException SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (db.role_has_permissions, CONSTRAINT role_has_permissions_role_id_foreign FOREIGN KEY (role_id) REFERENCES roles (id) ON DELETE CASCADE) (SQL: insert into role_has_permissions (permission_id, role_id) values (8f98272b-cbc3-459b-ab23-fc8fa86dd199, 0))

我已经正确地遵循了关于 UUID 和扩展的文档,但我仍然无法弄清楚我错过了什么,所以我无法 运行 我的种子。

rolepermission 数据已成功插入,尝试插入到 role_has_permissions pivot table.

时似乎遇到了麻烦

这是我对 permissionsrolesrole_has_permissions tables 的迁移:

Schema::create($tableNames['permissions'], function (Blueprint $table) {
      $table->uuid('id');
      $table->string('name');
      $table->string('guard_name');
      $table->timestamps();

      $table->primary('id');
});

Schema::create($tableNames['roles'], function (Blueprint $table) {
     $table->uuid('id');
     $table->string('name');
     $table->string('guard_name');
     $table->timestamps();

     $table->primary('id');
});

Schema::create($tableNames['role_has_permissions'], function (Blueprint $table) use ($tableNames) {
    $table->uuid('permission_id');
    $table->uuid('role_id');

    $table->foreign('permission_id')
        ->references('id')
        ->on($tableNames['permissions'])
        ->onDelete('cascade');

    $table->foreign('role_id')
        ->references('id')
        ->on($tableNames['roles'])
        ->onDelete('cascade');

    $table->primary(['permission_id', 'role_id'], 'role_has_permissions_permission_id_role_id_primary');
});

您需要将 Str::uuid() 转换为字符串 (string)Str::uuid()

$viewemployee = Permission::create(['id' => (string)Str::uuid(), 'name' => 'view employee']);

否则 ID 的 Permission 将是 UUID 对象而不是 UUID 字符串。
