Re: filter data with controller or model?

As a general rule, let the model do all the heavy lifting (fat models, thin controllers). It keeps the business logic in one place. What you have described below are two different things. The first is a find command called by the controller. The second is the code that associates this model with others. Both are important but do different things. The practice I adopt is to have methods within each model that accept parameters, do the finding and parsing and return a completed result. This can be called from another model or from a controller. For example, in the post model you might have a method:

public function findLatest($authorId = null, $limit = 3) {

if (!$authorId) {

return array();

}

return $this->find(

‘all’,

array(

‘conditions’ => array(‘Post.author.id => $authorId)

‘order’ => array(‘Post.created => ‘desc’),

‘limit’ => $limit

)

);

}

Then from the post controller you can call:

$lastThreePosts = $this->Post->findLatest($authorId, 3);

Or from the Author model (assuming Author hasMany Post):

$latestPost = $this->Post->findLatest($authorId, 1);

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' => ''              )      );  }
