我可以在 Laravel 中一次保存带有关系表的数据吗？

Question

I have two tables Lead and Comment . The relation is given below:

 public function comments(): MorphMany
    {
        return $this->morphMany(Comment::class, 'commentable');
    }

Working Code:

DB::transaction(function () use ($lead, $comment) {
            $lead->save();
            $lead->comments()->save($comment);
        });

But, my question is can I do it in a single line code, means only one save method?

You can use the push method to recursively save the model object and its relationship. So you might want to do something like:

DB::transaction(function () use ($lead, $comment) {
    $lead->fill([
        //some attributes to be updated.
    ]);
    $comment->fill(['lead_id' => $lead->id]);
    $lead->push();
});
