使用$data = FmapInfo::getOrFail($booth_id)->UploadFile()->where([])->delete($id);正常
DELETE FROM `upload_file` WHERE `upload_file_from_id` = 1001 AND `upload_file_type` = 'morphFmapInfo' AND `upload_file_id` = 12 [ RunTime:0.000689s ]

使用$data = FmapInfo::getOrFail($booth_id)->UploadFile()->delete($id);条件仅仅会出现$id
DELETE FROM `upload_file` WHERE `upload_file_id` = 12
