Laravel 实现关系模型取出需要的字段

 public function readOrganization($id) { $list = Organization::with(['authcodes' => function ($query) {$query->select('organization_id', 'auth_code');}])->find($id); if (empty($list)) { return '未查到结果！'; } $list = $list->toArray(); $list['authcodes'] = join(PHP_EOL, array_column($list['authcodes'], 'auth_code')); return view('organization/readOrganization', compact('list')); }
