拉拉维尔。在具有关系的模型中使用scope（）

Question

$categories = Category::with('posts')->published()->get();

class Category extends \Eloquent
{
    public function posts()
    {
        return $this->HasMany('Post');
    }
}

职位：

class Post extends \Eloquent
{
   public function category()
   {
       return $this->belongsTo('Category');
   }


   public function scopePublished($query)
   {
       return $query->where('published', 1);
   }

}

Answer 1

您可以内联进行：

$categories = Category::with(['posts' => function ($q) {
  $q->published();
}])->get();

您还可以定义一个关系：

public function postsPublished()
{
   return $this->hasMany('Post')->published();
   // or this way:
   // return $this->posts()->published();
}

后来呢：

//all posts
$category->posts;

// published only
$category->postsPublished;

// eager loading
$categories->with('postsPublished')->get();
