Hello I have Laravel validation request with these rules

```
 public function rules()
{
    return [
        'email' => 'unique:users,email|required|unique:invitations,email',
        'name' => 'string|required',
    ];
}

```

I want that "unique:users,email" would display one message and "unique:invitations,email" display other message. How to do that?

```
'unique:users,email' => 'This E-Mail address is already registered.',
'unique:invitations,email' => 'Invitation to this E-Mail address is already sent.',

```

It always returns default message for "unique" rule.

```
'unique' => 'The :attribute has already been taken.',

```
