Hola, soy nuevo en MVC.
[b]
Queria saber como mostrar las tablas relacionadas al buscar un pais que me muestre los paises y las tablas de las ciudades relacionadas.
Lo genere con gii y agregue manualmente las relaciones.
Yo se que el "CountrySearch" deberia cambiarlo pero no se exactamente que debo modicar en ese script y en la vista que debo cambiar?

Code sql of me tables
CREATE TABLE IF NOT EXISTS `bdyii`.`Country` (
`id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
`name` VARCHAR(45) NOT NULL,
PRIMARY KEY (`id`))
