I am using:
I am importing data from XML file. Import works fine, but I have problems with update.
I just can not get proper day_id in the loop.
$newest_day_id = $this->getNewestDayId();
...
->setParameter(7, $newest_day_id)
gives ID that is by 1 smaller than actual id
if I try:
$newest_day_id = $this->getNewestDayId();
...
->setParameter(7, $newest_day_id + 1)
it gives an error
An exception occurred while executing 'UPDATE item SET name_lv = ?, name_ru = ?, description_lv = ?, description_ru = ?, price = ?, in_stock = ?, day_id = ? WHERE unique_id = ?' with params ["EDIT My Product Name LV", "EDIT My Product Name RU", "EDIT", "EDIT", "999.00", "99", 34, "0361-my-product-unique-id"]:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`tevlvnews`.`item`, CONSTRAINT `FK_1F1B251E9C24126` FOREIGN KEY (`day_id`) REFERENCES `day` (`id`) ON DELETE CASCADE)
and if I try:
....
->setParameter(7, $day->getId)
I get NULL in the day_id field in the database

Thank you for your time and knowledge.
I managed to make it work.
