BelongsToMany relationship allows you to define which model key will be used in pivot table.
Primary Key is the default, but you can override it using:
class Rule {
public function websites()
{
return $this->belongsToMany(Website::class, 'rule_website', 'rule_id', 'website_code', 'id', 'code');
}
}
AttachMany fields send ids to the controller and use sync method to attach/detach related models.
It should use relatedKey (code in the example) instead of id.
