Question

I’ve 3 tables:
project, amenities and project_amenities.

I add project form only, i want to add new amenities, which first added to amenities table and then project_amenities table.

So I defined these relations:

Project hasMany Amenities

Amenity belongsTo Project

I declared in projects_controller:
var $uses = array('Amenity');

This gives error for my add action here

if (!empty($this->data)){

    $this->Project->create();

as

Notice (8): Undefined property: ProjectsController::$Project 
[APP\controllers\projects_controller.php, line 60]

edit
Also, I cannot do:

$this->Amenity->create();
$insertData = array('name' => $this->data['Project']['Amenity'][$i]['name']);
$this->Amenity->save($insertData);

I would like to suggest you to use $this->loadModel('ModelName'); in the function where you needed. Then you can use the model as below

$this->ModelName->function();

By using $uses array it make available to entire controller. Which will affect your performance.
