Problema de Noob en Yii Framework

soek

Buenos dias,

Estaba toqueteando Yii Framework, y viendo como hay una demo de un blog.

He estado leyendo toda la documentación, pero con inglés no me entero de mucho.

He averiguado que en view\post\view.php, es donde se edita la vista de cada post; luego que view\layout\main.php se edita la vista del home del blog.

A mi me interesa editar el GRID del blog. En la documentación dice que en los modelos hay una Clase Post que extiende CActiveRecord (:S), que contiene la función search() y desde alli hay un sort y se controla como ordenar el GRID, pero no me cuadra y no me funciona ningun cambio.

Yo quiero solo invertir de orden los posts, habia pensado en cambiar simplemente de ASC a DESC, en la query, pero que tampoco encuentro en modelos...

Quería saber si algien está acostumbrado a este framework, yo vengo de CodeIgniter y todo era mas chapucero, y la documentación en español era decente. Algien sabe que es lo que me falta saber, o algun sitio donde esté bien explicado, sería de infinita ayuda.

rpv: Acabo de empezar con yii y voi perdido y la documentación in inglish es una mierda.

F

Para el Cgridview es correcto que se edita en search o la función a la que asocies, utilizando CSort puedes configurarlo si,

Pon el código (Modelo y vista) y me lo miro.
