Re: Trying to figure out the the correct way of doing things...

Hi Evangelos

A simpler way to do this would be to set a variable to the view. So,
you wouldn't need to call the controller every time. Rather, in the
controller where you setup the view do the following

function showPost($id) {
$post = $this->Post->findById($id);
$videos = $this->Post->Postvideo-
>find('first',array('conditions'=>array('Postvideo.post_id'=>$id)));
$this->set('post', $post)
$this->set('hasVideo', !empty($videos));
}

This will return your single post along with a boolean to tell you if
you have a video. This can scale to multiple posts easily enough if
you use recursive=0, and then check if there's a Videopost item
returned as part of the post.

Hope that makes sense.
