Laravel

Question

我是 laravel 的新手，正在尝试从 permissions table 中获取设置到 roles - permission 中的所有权限行字段作为 json

Obviously, this is not working as aspected. It returns an array of collections. However, I want each permission rows that associate with the roles results in itself.

public function index()
{
    $roles = Role::all();

    foreach ($roles as $role) {
        $permissions[] = Permission::whereIn('id', json_decode($role->permission))->get();
    }

    dd($permissions);

}

权限table

角色table

建议将权限字段提取到单独的table。这将使实施约束以确保引用的权限 ID 和角色 ID 确实存在成为可能。可能的 table 名称将是：permission_role，包含以下列：permission_id 和 role_id.

迁移可以这样设置：

Schema::create('permission_role', function (Blueprint $table) {
    $table->unsignedBigInteger('permission_id');
    $table->unsignedBigInteger('role_id');

    $table->foreign('permission_id')->references('id')->on('permissions');
    $table->foreign('role_id')->references('id')->on('roles');
});
