我有一个laravel User模型,它有一个唯一的username和emailvalidation规则。 在我的知识库中,当我更新模型时,我重新validation这些字段,以便不需要规则validation的问题: public function update($id, $data) { $user = $this->findById($id); $user->fill($data); $this->validate($user->toArray()); $user->save(); return $user; } 这在testing中失败 ValidationException: {"username":["The username has already been taken."],"email":["The email has already been taken."]} 有没有一种方法来优雅地解决这个问题?
