Unique validation

I have a model supporter. I need to when signing up check that a id_number does not exist on supporter and this is fine I get this but I also need to check if the id_number does not exist on members table, because a supporter could be upgraded to member we need to check if the member does not already exist. so what i have is this ->unique(table: Supporter::class, ignoreRecord: true) ->unique(table: Member::class, ignoreRecord: true) the supporter works fine but then the member is also looking for supporter id in members table which it does not have SQLSTATE[42S22]: Column not found: 1054 Unknown column 'supporters.id' in 'where clause' select count(*) as aggregate from members where id_number = 1234 and supporters.id <> 2 how can i get this to work?

I think you need to join the supporters table and have one unique rule. I dont know how to do this exactly because I have not worked much with the unique rule... But it does seem like you can modify the rule:

Field::make('email')
    ->unique(modifyRuleUsing: function (Unique $rule) {
        return $rule->where('is_active', 1);
    })

Field::make('email')
    ->unique(modifyRuleUsing: function (Unique $rule) {
        return $rule->where('is_active', 1);
    })

It says in the doucmentation that it looks for the Model so I would think you can somehow extend the rule with $rule->join('supporters') or something? Not sure though! the laravel documentation indeed gives you the option to use the Builder: 'email' => Rule::unique('users')->where(fn (Builder $query) => $query->where('account_id', 1)) So I think it is possible to join the supporters table
