CakePHP 2.3.0 tutorial blog: Model file name and validation problems

I'm trying to learn CakePHP by doing tutorial blog (but that tutorial is 2.2 -
mayby that's the problem) and I'm having two problems.

When I name model file as Post.php, then every page outputs model at the top
of web page.
Like this:
class Post extends AppModel { public $validate = array( 'title' =>
array( 'rule' => 'notEmpty' ), 'body' => array( 'rule' => 'notEmpty' ) );
} class Post extends AppModel { public $validate = array( 'title' =>
array( 'rule' => 'notEmpty' ), 'body' => array( 'rule' => 'notEmpty' ) ); }
Also, when I add new post or delete post, then browser remains on a page,
that displays that model source on white background.
When I rename model file to post.php, then I don't get that model output
and deleting/adding post correcly redirects to index page.
But from what I understand, the model file is supposed to be named Post.php.
And that output does not depend debug settings.

Another problem is, that no matter what is the filename of model,
validation is never done.


PS: I'm using tutorial from
http://book.cakephp.org/2.0/en/tutorials-and-examples/blog/blog.html
