In cakephp what is the method to filter data on a database request.
Do I filter the data from a model or a controller?

Say if I have a table with 1000's of rows and I only want to select rows on 
a condition , like a where clause on sql.

The user enters in a certain fields to select rows from a table.

I then pass this variable to the controller and the controller filters this 
data or is the model supposed to filter the rows selected?

I didnt quite see this clearly from the cakephp docs.
I am not sure if a model or controller is the best way to go about it.

a controller would do ///
 public function view($id = null) {
      $post = $this->Post->findById($id);

    
        $this->set('post', $post);
    }

a model would do something like the below where you set the condition and this 
seems a really messy way to go about things.

class Recipe extends AppModel {
    public $hasAndBelongsToMany = array(
        'Ingredient' =>
            array(
                'className' => 'Ingredient',
                'joinTable' => 'ingredients_recipes',
                'foreignKey' => 'recipe_id',
                'associationForeignKey' => 'ingredient_id',
                'unique' => true,
                'conditions' => '',
                'fields' => '',
                'order' => '',
                'limit' => '',
                'offset' => '',
                'finderQuery' => '',
                'with' => ''
            )
    );
}
