Flush page from cache after updating database

Yii 1.1 General Discussion

I have a site where I’ve got page caching set up and working perfectly. Here’s an example : http://www.thebigeat.com/takeaway/paradise_take_away

When a person adds a new review, I’d like to delete the cached version of the view takeaway page (otherwise their review won’t show up for 12 hours). Any ideas?

class Review extends CActiveRecord

{

...

    protected function beforeSave($checkAccess = true)

    {

        if ($this->isNewRecord) {

            // Delete cache

        }

        return parent::beforeSave();

    }

}

That’s great, but it’s the actual code to delete the cache of the view page that I can’t figure out.
