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).

My doubt is, I had few tables named client1,client2,client3 etc., I need to get the data of each client in single controller without creating any model/controller for each table. Can any one explain how to get those values.
You can use dynamic models
app/client_model.php
<?php
class ClientModel extends Model {
var $name = 'Client';
var $alias = 'Client';
function __construct($table) {
$this->useTable = $table;
parent::__construct();
}
}
?>
And Use like this for client1 table
App::import('model','Client');
$client = new ClientModel('client1');
$client->find('all');
You Can do it by firing normal mysql queries selecting table and fetching values
in controller as we do in core php.
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');
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:
$this->loadModel('User');
I am using an afterFind function to modify data from a find function. It works fine. If I move the afterFind function into a behavior (in a plugin) it still works, but only when the model of interest is the primary model, i.e. it isn't called when the model belongsTo another model. Is there any way round this? I'm using cake 1.3.4. This is a simplified version of the behavior:
class ChemicalStructureBehavior extends ModelBehavior {
function afterFind(&$model, $results, $primary) {
foreach ($results as &$unit) {
// format chemical formula (with subscripts)
$unit[$model->alias]['chemical_formula_formatted'] = preg_replace('/([0-9]+)/i', '<sub>$1</sub>', $unit[$model->alias]['chemical_formula']);
}
return $results;
}
}
I guess I'd do one of 2 things depending on how generically the code block applies:
Universal version: not use a behavior, but include your method block in AppModel::afterFind
Surgical version: use a behavior and attach it to each model that needs to share the functionality.
A behavior isn't supposed to work on related models, for example, if you have this two models:
app/models/product.php
<?php
class Product extends AppModel{
var $belongsTo = array('Category');
var $actsAs = array('SomeBehavior');
}
?>
app/models/category.php
<?php
class Category extends AppModel {
var $hasMany = array('Product');
}
?>
SomeBehavior will only be executed when calling methods for Product, because the behavior isn't associated with Category

Set up an event that does the formatting - trigger that event however you need to. Easy as Cake.
I intended to create a controller that handles a contact page. I created the controller ContactsController. The problem is that it is asking for a table with the same name:
Missing Database Table
Error: Database table
username_contacts for model Contact
was not found.
Notice: If you want to customize this
error message, create
app/views/errors/missing_table.ctp
Do I really need to create a table with no data for this?
This is my controller code:
<?php
class ContactsController extends AppController {
var $name = 'Contacts';
function index($id = null)
{
$this->set('page', ClassRegistry::init('Page')->findByShortname($id));
}
}
var $name = 'Contacts';
var $uses = array();
not to be that guy, but this is documented well.

You might want to create the model anyway as you'll almost certainly find you need to do some database type stuff. It doesn't need to use a db_table:
class ModelWithoutTable extends AppModel
{
var $useTable = false;
}
Think "fat model - thin controller"
