Doctrine throwing error connected with field not related to current operation - symfony

Question

I'm currently doing app that's similar to imgur and I'm receiving following error
An exception occurred while executing 'INSERT INTO user_gallery_views (gallery_id, user_id) VALUES (?, ?)' with params [1, 1]:
SQLSTATE[23000]: Integrity constraint violation: 19 UNIQUE constraint failed: user_gallery_views.gallery_id, user_gallery_views.user_id
It occurs while calling path to add object as saved in users collection

The point I don't get is why error concern user_galler_views when it's not even used in /image/{id}/save?
I'm for sure not seeing something but don't even know what, so I'm full of hope u gonna help me

Answer 1

It looks like you are storing the entity to the wrong Array.
public function addSave(User $save): self
{
if (!$this->saves->contains($save)) {
$this->views[] = $save;
}
return $this;
}
You check for $this->saves->contains($save) but then you store the data not to saves but to views.
$this->views[] = $save;
It is probably a coincidence that the save entity has the same id as another view entity that is already assigned to the gallery.
