Unique validation rule ignored

[paoloveggi]

Hello guys,

I have the following validation rules on a store context:

'code' => [ 'required', 'max:30', Rule::unique('mongodb.plico_user_groups', 'code')->where('company_id', 1) ]

but the check for the unique key is ignored. I want to have a unique index based on the fields "code" and "company_id". If I try to insert twice the same "code" for the same "comapny_id" the rule doesn't fire as expected. In MongoDB fields are of type string for "code" and of type Int32 for "company_id". In above Rule::unique('mongodb.plico_user_groups', 'code') the "mongodb" part is the name of my connection and "plico_user_groups" is the name of the collection.

Please, someone can help?

Many thanks,
bye.
