我如何使用whereHas在雄辩中从相关音标表中获取数据

Question

我在用雄辩，有什么帮助吗?

return House::whereHas('extendable', function($extendUnits) use($projectdeciphered){
$extendUnits->where('project_id', $projectdeciphered);
});

Answer 1

你可以使用如下所示的whereHasMorph:https://laravel.com/docs/9.x/eloquent-relationships querying-morph-to-relationships

House::whereHasMorph('extendable', [Extend::class, Unit::class], function($extendUnits) use($projectDeciphered){
$extendUnits->where('project_id', $projectDeciphered);
});

希望这对你有帮助。
