关系Laravel的更新值

Question

我尝试通过关系更新2个模型的值，但是我的方法似乎不太“ Laravel方法”，这样做有更好的方法吗？

$question = new Question();
$question->where('id', $id)->update([
    'free_text' => $request->free_text,
    'title' => $request->title,
    //here I have a topics_id 
]);

$question_topics = new QuestionTopics();
$question_topics->where('id', $request->topics_id)->update([
    'best_match_topic' => $request->best_match_topic,
    'topic_1' => $request->topic_1,
    'topic_2' => $request->topic_2,
    'topic_3' => $request->topic_3,
]); 

从型号：

public function questions()
{
    return $this->belongsTo(Question::class);
}

public function question_topics()
{
    return $this->hasOne(QuestionTopics::class, 'id');
}

Answer 1

您需要首先在关系中添加param作为topic_id。
