Change Default Validation Messages

If you want to change default validation error message for specific field and specific validation rule, just add a messages() method into your FormRequest class.

class StoreUserRequest extends FormRequest
{
    public function rules()
    {
        return ['name' => 'required'];
    }
 
    public function messages()
    {
        return ['name.required' => 'User name should be real name'];
    }
}
