Estou criando um site onde os membros podem adicionar dados através de um formulário conectado a uma coleção CMS, mas gostaria que cada membro pudesse adicionar apenas 1 vez. Ex. um site para venda de carros, onde os membros podem cadastrar seus carros para venda, mas cada membro só pode cadastrar um carro. Como faço para limitar a quantidade de dados enviados ao CMS?

You can do that with custom coded functionality

Instead of allowing members to add records to a collection, disable that permission, and simply allow them to edit their own records

Then, in the backend, create functionality which checks if a member has a car created, and if not, create a record and assign the member ID as `_owner`
