I'm still trying to migrate from CakePHP 1.3 to 2.0
I have a Controller UsersController and its Model User.
The class User has some constants which I could easily access from the UsersController using User::constant. But for CakePHP 2.0 it doesn't work: I get an error saying the User class is not found. It works if I App::Import('Model', 'User');.
It sure has to do with their built-in lazy loading in 2.0!
you simple need to tell this file that it has other dependencies
do that at the very top of your UserController file:
<?php
App::uses('User', 'Model');
then everything works fine
You can try setting the controller name (in UsersController):
var $name = 'Users';
Or using the "uses" var (in other controllers:
public $uses = array('User');
Does that not work?
Did you declare the name of the model like that ?
class User extends AppModel {
public $name = 'User';
}
Do you have others variables in your UsersController ?
I set variables in the model like this:
//Person model
public $genders = array('m' => 'male', 'f' => 'female');
Then get them from the controller like this:
//People controller
$genders = $this->Person->genders;
No special code needed. (Is this what you're talking about?)
Also, I don't believe you need to set the $name variable anywhere anymore - I think that was just for PHP 4. (not 100% on that part, but... I don't ever set that anymore, and my Cake2 apps run fine)
You have to load the model like this:
$this->loadModel('User');

Can I use another Model inside one model?
Eg.
<?php
class Form extends AppModel
{
var $name='Form';
var $helpers=array('Html','Ajax','Javascript','Form');
var $components = array( 'RequestHandler','Email');
function saveFormName($data)
{
$this->data['Form']['formname']=$data['Form']['formname'];
$this->saveField('name',$this->data['Form']['formname']);
}
function saveFieldname($data)
{
$this->data['Attribute']['fieldname']=$data['Attribute']['fieldname'];
}
}
?>
Old thread but I'm going to chime in because I believe the answers to be incomplete and lacking in "why". CakePHP has three ways to load models. Though only two methods work outside of a Controller, I'll mention all three. I'm not sure about version availability but this is core stuff so I believe they'll work.
App::import() only finds and require()s the file and you'll need to instantiate the class to use it. You can tell import() the type of class, the name and file path details.
ClassRegistry::init() loads the file, adds the instance to the object map and returns the instance. This is the better way to load something because it sets up "Cake" things as would happen if you loaded the class through normal means. You can also set an alias for the class name which I've found useful.
Controller::loadModel() uses ClassRegistry::init() as well as adds the Model as a property of the controller. It also allows $persistModel for model caching on future requests. This only works in a Controller and, if that's your situation, I'd use this method before the others.
You can create instances of other models from within any model/controller using one of these two methods.
If you're using Cake 1.2:
App::import('model','Attribute');
$attr = new Attribute();
$attr->save($dataYouWantToSavetoAttribute);
If you're using Cake 1.1:
loadModel('Attribute');
$attr = new Attribute();
$attr->save($dataYouWantToSavetoAttribute);
An obvious solution everyone missed is to create an association between two models, if appropriate. You can use it to be able to reference one model from inside another.
class Creation extends AppModel {
public $belongsTo = array(
'Inventor' => array(
'className' => 'Inventor',
'foreignKey' => 'inventor_id',
)
);
public function whoIsMyMaker() {
$this->Inventor->id = $this->field('inventor_id');
return $this->Inventor->field('name');
}
}
In CakePHP 1.2, it's better to use:
ClassRegistry::init('Attribute')->save($data);
This will do simply
<?php
class Form extends AppModel
{
//...
$another_model = ClassRegistry::init('AnotherModel');
//...
}
?>
In CakePHP 3 we may use TableRegistry::get(modelName)
use Cake\ORM\TableRegistry;
$itemsOb = TableRegistry::get('Items');
$items = $itemsOb->find("all");
debug($items);
If you want to use Model_B inside Model_A, add this line at the beginning of Model_A file:
App::uses('Model_B_ClassName', 'Model');
and then you will be able to use it inside Model_A. For example:
$Model_B = new Model_B_ClassName();
$result = $Model_B->findById($some_id);
var $uses = array('ModeloneName','ModeltwoName');
By using $uses property, you can use multiple models in controller instead of using loadModel('Model Name').
App::import('model','Attribute');
is way to use one model into other model. Best way will be to used association.
I'm writing an installation script for my CakePHP web application. I have a InstallController with 6 actions: step1, step2, step3, etc.
At step1 I'm handling Config/database.php creation. Because this file is empty and no datasource is available I have to set public $uses = false; in the InstallController.
At step2 the Config/database.php file is set so I should be able to make a connection to the datasource. This is also necessary because I want to update some database fields in the following steps.
Is it possible to update the public $uses = false; in every following steps after step1?
I'm using CakePHP version 2.3.5
Have you considered loading the model within the actions? So, something like:
<?php
App::uses('AppController', 'Controller');
class InstallController extends AppController {
public $uses = false;
public function step1() {
}
public function step2() {
$this->loadModel("Install");
$this->Install->callMethod();
}
}
In CakePHP 2.x models are lazy loaded, so as long as your step1 action doesn't try to make use of a model, you can safely declare the models in your controllers $uses property, they are not being constructed until your code actually makes use of them.
However, if for some reason you'd actually need to modify $uses, well then just do it, as mentioned models are lazy loaded, so you can modify $uses whenever you want and then access the models afterwards via magic properties on the controller.
I tried all the suggested solution for this problem which is clearing your cache folders. I also disable the cache Configure::write('Cache.disable', true); My debug level is set to 2. But I always get a same error. The table that is missing is only new added table. By the way, I'm only running in my localhost.
this is my model named Department.php
<?php
class Department extends AppModel {
public $name = 'Department';
}
?>
this is my controller name DepartmentsController.php
<?php
class DepartmentsController extends AppController {
public $name = 'Departments';
public $helpers = array('Html', 'Form','Session');
public $components = array('RequestHandler','Session');
function index() {
$this->Department->recursive = 0;
$this->set('departments', $this->paginate());
}
}
?>
Advance thank you for the answer! :D
Assuming you are actually using a database I would try the following things:
If your database table isn't named using the cakephp conventions, manually set it:
public $useTable = 'table_name';
Make sure your database config is using the right database in app/config/database.php
If that model is in a plugin, use the plugin syntax when including it in the controller:
public $uses=array('PluginName.Department');
We are experiencing an issue when an invalid url is passed to cake. This loads the missing_controller.ctp view correctly but $_SESSION variable is empty.
We have tested this on 1.3 and 2.0 and in both version $_SESSION is empty when the missing_controller view is rendered.
Is this done on purpose?
Thanks

Did you imported the Session component in Controller? Like this:
<?php
class MissingController extends AppController{
var $components = array('Session');
var $helpers = array('Session');
}
Try to access the data in $_SESSION with $this->Session->read('This.That');
I'm new to cakePhp development. I've stuck on following problem:
I've made few models, controllers and views - it works great. The problem is that after production, I have to made new table(Transactionaltemp table and corresponding model and controller ) in the db that logically is "connected" to other tables, but technically does not needs to - for ex. it holds temporary info on user_id, time, ip and similar. So, other tables doesn't need to be directly connected to that.
The problem is when I try (in some other controller than transactionaltemps_controller):
$this->loadModel('Transactionaltemp');
I get error - the model is not found (it is true because the model is missing in the cache). Interesting enough transactionaltempls_controller is in the cache (in the cake_controllers_list file).
I tried following stuff to resolve the problem:
clear cache
disable cache
tried using uses={..} code in the controller that I would like to use mymodels_controller
tried using init('Transactionaltemp')
with no success. Here is corresponding code:
The model:
<?php
class Transactionaltemp extends AppModel
{
var $name = 'Transactionaltemp';
function beforeSave() {
return true;
}
}
?>
The controller:
<?php
class TransactionaltempsController extends AppController
{
var $name = 'Transactionaltemps';
var $scaffold;
}
?>
I'll very grateful to any help!!!
App:Import('Model','Transactionaltemp');
$this->Transactionaltemp= new Transactionaltemp;
I hope this may work
If you are connecting to a table name with different name than your model, you must specify the table name in it:
<?php
class Transactionaltemp extends AppModel
{
var $uses = 'Transactional';
var $name = 'Transactionaltemp';
function beforeSave() {
return true;
}
}
Try
App::Import('Model', 'YourModelName');
in your controller (or where you want).
