Laravel. Use scope() in models with relation

Question

I have two related models: Category and Post.

The Post model has a published scope (method scopePublished()).

When I try to get all categories with that scope:

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

I get an error:

Call to undefined method published()

Category:

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

Post:

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


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

}

You can do it inline:

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

You can also define a relation:

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

and then:

//all posts
$category->posts;

// published only
$category->postsPublished;

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

Incidentally, if you want to ONLY get where you have published posts: Category::whereHas('posts', function ($q) { $q->published(); })->get();

@tptcat yes. Also can be Category::has('postsPublished') in this case

Clean question, clean answer!

What if the query scope has a parameter?

This solution is very clean rather than pass an ugly function after array key 'with' method
