If you’re using Laravel Nova to create a dashboard to manage your resources, you’ve almost certainly ended up looking at this code from https://github.com/laravel/nova-issues/issues/156#issuecomment-415974405
public static $defaultSort = ['id' => 'asc'];
/**
* Build an "index" query for the given resource.
*
* @param \Laravel\Nova\Http\Requests\NovaRequest $request
* @param \Illuminate\Database\Eloquent\Builder $query
* @return \Illuminate\Database\Eloquent\Builder
*/
public static function indexQuery(NovaRequest $request, $query)
{
if (static::$defaultSort && empty($request->get('orderBy'))) {
$query->getQuery()->orders = [];
return $query->orderBy(static::$defaultSort);
}
return $query;
}This is the accepted way to set a default sort order for your resource. It’s great as far as it goes, but what if you want to sort on multiple columns? The code above assumes $defaultSort contains a single array. That’s not gonna work.
public static function indexQuery(NovaRequest $request, $query)
{
if (static::$defaultSort && empty($request->get('orderBy'))) {
$query->getQuery()->orders = [];
foreach (static::$defaultSort as $field => $order) {
$query->orderBy($field, $order);
}
}
return $query;
}
This function loops over the entire array and adds each entry to the query, so we can define our default sort as
public static $defaultSort = [
'group' => 'asc',
'id' => 'asc'
];
