How To send data form Controller to other Model? - cakephp

Question

I create view for register and send data to controller
//app::import('Model','Myprofile');
Class MembersController extends AppController {
var $name = 'Members';
var $helpers = array('Form', 'Session');
var $uses = array('Myprofile'); //
function register() {
//$myprofile = new Myprofile();
if (!empty($this - > data)) {
$this - > Member - > create();
if ($this - > Member - > save(($this - > data['Member']['username']), ($this - > data['Member']['password'])) && $this - > Myprofile - > save(($this - > data['Myprofile']['name']), ($this - > data['MyProfile']['address']), ($this - > data['Myprofile']['phonenumber']))) {
$this - > redirect('index');
}
} else {
$this - > Session - > setFlash('failed');
}
}
I want to send data form memberscontroller to Myprofile Model
I try to use
$use = array('Myprofile');
i got
Undefined property: MembersController::$Member
when I use
//app::import('Model','Myprofile');
//$myprofile = new Myprofile()
i got
Undefined property: MembersController::$Myprofile
I do not know the right way or not
There is also another way to fix my problem
Thank for any advice

Answer 1

The $uses array will only give you access to the models you specify in it.
If you'd commented out $uses, you would still have access to $this->Member model by default since you are in the Members controller.
Once you add another model to the $uses array, you must remember to include your initial model as well.
I've also found that in some cases, it's very useful to make sure that when you're doing something like that, you should specify your default model FIRST
var $uses = array( 'Member', 'Myprofile' );
Otherwise you might get unexpected results from actions like $this->paginate()

Answer 2

If you use the $uses array, make sure that you have the current model included in that array as well. Otherwise the current model does not get included by default if you define a specific $uses array.
If MyProfile is related to Member you can access it via
$this->Member->MyProfile; //depends on associations
You can also use App:import
App:import('Model', array('Myprofile')); //loads the class
$myProfile = new MyProfile();
// OR
MyProfile::staticMethod();

Answer 3

You have to add both models to your $uses array:
var $uses = array('Myprofile', 'Member');

Answer 4

try to use $this->loadModel('Myprofile'); in your action.
and are you sure your model name is 'Myprofile' ?
you can even debug it to see if it return true or false. this will help you find if the model has been correctly instancieted.

Answer 5

You can invoke any public methods of related models in normal way. for eg
In Profile.php
function someMethod( $param = null ) {
// some definition
}
From MembersController.php
function register ( ) {
$this->Member->Profile->someMethod( $my_data_to_pass ); // if related
/* if not related
$this->loadModel('Profile');
$this->Profile->someMethod($my_data_to_pass);
*/
}
As a side note, if you ran into this situation for making urls more sensible, Please look into Router (http://book.cakephp.org/2.0/en/core-utility-libraries/router.html)
