将ID数组添加到Laravel中的其他表中

Question

我有两个故事故事和精选故事，所以我想在单个请求中将几个故事ID添加到精选表格。怎么做？

这是我的代码，用于将单个ID添加到精选故事表中。

public function saveFeatured($id)
    {
        # code...
        $story = $this->getById($id);
        $storyId = $story->id;
        $featured = new FeaturedStory();
        $featured->story_id = $storyId;
        $featured->save();
        return "Added to featured StoryList";
    }

Answer 1

将id的数组传递给函数，然后执行此操作。

public function saveFeatured($arrayid){
    foreach($arrayid as $key => $item){
        $story = $this->getById($item);
        $storyId = $story->id;
        $featured = new FeaturedStory();
        $featured->story_id = $storyId;
        $featured->save();    
    }
    return "Added to featured StoryList";
}

Answer 2

签出：has-many-create-relationship

在您的Story.php模型中：

public featuredStoreis() {
    return $this->hasMany(\App\FeaturedStory::class, 'story_id', 'id');
}

在您的FeaturedStory.php模型中：

public story() {
    return $this->belongsTo(\App\Story::class);
}

然后您可以轻松地创建featured_storeis；

$array = ... # your featured_stories attributes array.
$story->featuredStories()->createMany($array);

这将自动填充story_id中的FeaturedStory

Answer 3

您可以使用saveMany（）或createMany（）方法。首先，用几个项目填充一个数组，然后一次有效地存储它们。在问题的注释中也使用@Cerlin甲硫氨酸原始插入方法。

我不知道您如何获得输入以及“功能”的确切含义是什么，但看起来可能像这样：

$story->featured()->saveMany([
    new App\Featured(['id' => 1, 'title' => 'First story']),
    new App\Featured(['id' => 2, 'title' => 'Another story']),
]);
