Laravel Request validation exists and nullable at the same time

Question

I created a request class and inject it into the store method of the controler. My Rules method within the class has the following key:

public function rules()
{
    return [
    //...
    'campo_id' => 'sometimes|nullable|exists:tabela,pk',
    //...
    ];
}

when the value is null and enters this validation, it falls into the exists validation and returns the corresponding message. My intention is to leave null itself. Any suggestions?

Answer 1

You can use it that way

    public function rules()
{
    return [
    //...
    'campo_id' => 'nullable|exists:tabela,pk',
    //...
    ];
}
