Filter hasMany relationships

Just a code example from my project, showing the possibility of filtering hasMany relationships.

TagTypes -> hasMany Tags -> hasMany Examples

And you wanna query all the types, with their tags, but only those that have examples, ordering by most examples.

1$tag_types = TagType::with(['tags' => function ($query) {
2    $query->has('examples')
3        ->withCount('examples')
4        ->orderBy('examples_count', 'desc');
5    }])->get();
