我想要一個集合,將它按1個字段分組,並按多個字段排序。Laravel group by 1 order by multiple
這件事情我已經試過:
$permission_groups = collect(Permission::orderBy('group', 'asc')->orderBy('name', 'asc')->get());
$permission_groups->groupBy('group');
原因Trying to get property of non-object
$permission_groups = Permission::all()->sortBy('group', 'asc')->sortBy('name', 'asc')->groupBy('group');
導致對集合進行排序,然後使出。
我該如何簡單地按2列進行排序並對其進行分組?
