                        )
                )
        )
)

in the above array there is a all comment of that image. I don’t want here comment list I just want no of comments .

Answer 1

Could you post the find statement you’re using. You can set recursive to a certain level, from the documentation:

• -1 Cake fetches Group data only, no joins.
• 0 Cake fetches Group data and its domain
• 1 Cake fetches a Group, its domain and its associated Users
• 2 Cake fetches a Group, its domain, its associated Users, and the Users’ associated Articles

So you can call the following if you only want the data from the current model only:

$this->Model->find('all', array('recursive' => -1));

There is also the Containable behavior, which allows you to specify which Model data you want to retrieve when calling find.

Say you have a Post model which hasMany Image. The call, with the Containable behaviour in the Post Model properly included, would be:

$this->Post->find('all', array(
 'conditions' => array('Post.id' => 1),
 'contain' => array('Image')
));

EDIT:
Because of the spelling and formatting I misread your initial question. I thought you wanted “no comments” to appear in the data array, instead you want only the “number of comments” to appear.

If you want the comment count, use counterCache as Kishor Kundan proposes.
