Cake PHP - How to access a special Model found by Pagination? - cakephp

I have the following Code to get a special model related to another model related to actual object: (I want the Entry-model - in the Rubric-model-view)
$this->paginate = array(
'Entrieslocation' => array(
'conditions' => array('Entrieslocation.rubric_id' => $this->Rubric->id, 'Entrieslocation.subrubric_id' => '0'),
'joins' => array(
array(
'alias' => 'Entry',
'table' => 'entries',
'type' => 'INNER',
'conditions' => 'Entry.id = Entrieslocation.entry_id'
)
)
)
);
Then I thought I could get it by something like this:
$this->set('entries', $this->paginate('Entry'));
But the variable is empty, how can I access the Entries inside the Pagination in the view?
The Query generated by the code above is correct, I checked it by entering the query into phpmyadmin. So how can I access the result (only the Entries)?
Thanks for your help :)

First of all you must define $paginate variable below controller class. For example
class UsersController extends AppController {
public $paginate = array();
}
Then in your action follow following patter to get the paginated result.
$this->paginate = array(
'recursive' => -1,
'limit' => 10,
'conditions' => array('Your conditions'),
'fields' => array('Entry.*, Entrieslocations.*'),
'joins' => array(
array(
'table' => 'Entrieslocations',
'alias' => 'Entrieslocation',
'type' => 'inner',
'conditions' => 'Entry.id = Entrieslocation.entry_id'
),
),
'order' => array(
'Entry.id' => 'desc'
)
);
$entries = $this->paginate('Entry');
To pass result set to the view use following:
$this->set('entries', $entries);

cake 2.5.1 bind 2 models together

I have a model Ranking which holds a contact_id and belongsTo Model Contact.
Model Contact has a costumer_id and belongsTo Model Costumer.
And hasMany Rankings.
There is also a Model Product which hasMany Ranking.
On a statistics page I select
$this->Product->recursive = 1;
$this->set('products', $this->Paginator->paginate())
;
and I get the array of
array(
'Product' => array(
'id' => '69',
),
'Ranking' => array(
(int) 0 => array(
'id' => '29',
'contact_id' => '9',
'product_id' => '69',
'ranking' => '9',
),
I would like to bind now the Contact and Costumer to the ranking based on the contact_id.
Is this manually possible via bindModel?
If yes, how can I do that?
I tried to set $this->Product->recursive = 1; to 2 and 3, but that select so many other things which I would need to clear with unbindModel... So I hope there is a smarter way of bind those model to get to the data...?
What you basically want to use is containable behavior. With this behavior you are able to filter and limit model find operations. You have the possibility to add this behavior on model level or at the controller to avoid side effects if the application has already grown to a complicated level.
Example from Cake-Book:
// Activate Containable Behavior on the fly in a controller
$this->User->Behaviors->load('Containable');
$this->User->contain();
$this->User->find('all', array(
'contain' => array(
'Profile',
'Account' => array(
'AccountSummary'
),
'Post' => array(
'PostAttachment' => array(
'fields' => array('id', 'name'),
'PostAttachmentHistory' => array(
'HistoryNotes' => array(
'fields' => array('id', 'note')
)
)
),
'Tag' => array(
'conditions' => array('Tag.name LIKE' => '%happy%')
)
)
)
));
Hope this gives you a push into the right direction.
using find it will get me the right data with this:
$this->set('products', $this->Product->find('all', array(
'contain' => array(
'Ranking' => array(
'Contact' => array(
'foreignKey' => 'contact_id',
'Customer' => array(
'foreignKey' => 'customer_id',
)
)
)
)
)));
When using the Paginator it looks like
$this->Paginator->settings['contain'] = array(
'Ranking' => array(
'Contact' => array(
'foreignKey' => 'contact_id',
'Customer' => array(
'foreignKey' => 'customer_id',
)
)
)
);
$this->Product->Behaviors->load('Containable');
$this->set('products', $this->Paginator->paginate());
Thanks so much!!

CakePHP 2 How to find last record with hasn't related model empty

I use find('first') with order by created field for return last record from table.
But I would like return last record if his related model isn't empty.
It is possible?
Edit:
I add code, but doesn't work:
$last_project = $this->Project->find('first', array(
'conditions' => array(
'COUNT(ProjectPhoto.id) >' => 0),
'joins' => array(
array(
'table' => 'project_photos',
'alias' => 'ProjectPhoto',
'type' => 'INNER',
'conditions' => array(
'Project.id = ProjectPhoto.project_id'))),
'order' => 'Project.created DESC'));

How to pass a variable in the variable var $paginate with CakePHP

My pagination worked perfectly like this :
var $paginate = array(
'Article' => array(
'conditions' => array(
'Article.visible' => true),
'order' => array('Article.creation_date DESC', 'Article.id DESC'),
'limit' => 11
)
);
But I want to filter my articles with a publication date like this
var $paginate = array(
'Article' => array(
'conditions' => array(
'Article.visible' => true,
'Article.publication_date <= ' => date('Y-m-d H:i:s')),
'order' => array('Article.creation_date DESC', 'Article.id DESC'),
'limit' => 11
)
);
But the date() function does not seem to be accepted.
It's not the good syntax.
Does anyone can help me?
Thanks a lot in advance.
If you want to do this, you will have to use $this->paginate = array() either in the action that you are paginating in, or in the __construct() function.
You cannot execute functions like that when the object is instantiated.
This is true for any type of method call at runtime.
You can't use a function in the declaration of an array at the class level. What you could do is to use a beforeFilter() callback in your controller to initialize the $paginate variable like this:
function beforeFilter()
{
parent :: beforeFilter();
$this->paginate = array(
'Article' => array(
'conditions' => array(
'Article.visible' => true,
'Article.publication_date <=' => date('Y-m-d H:i:s')),
'order' => array('Article.creation_date DESC', 'Article.id DESC'),
'limit' => 11
)
);
}

Joining models in cake php

I have this NPO table which has one template. A template in turn has a theme. I want to retrieve which theme was selected by Npo.
I have following relation setup:
NPO - template on npo.id = template.npoid Template - theme on theme.id
= template.template_theme_id
And I am using:
$this->Npo->bindmodel(array(
'hasOne' => array(
'NpoTemplate' => array(
'className' => 'NpoTemplate'
)
)
), false);
$this->NpoTemplate->bindmodel(array(
'hasOne' => array(
'TemplateTheme' => array(
'className' => 'TemplateTheme',
'fields' => 'TemplateTheme.html'
)
)
), false);
$arrUserSite = $this->Npo->find('first', array(
'conditions'=> array(
'Npo.address' => $user
)
));
But it does not fetch anything from TemplateTheme. Instead it writes a seperate query for this table and does not consider it in the join.
I have set recursive level to 3
Please help. I don't really understand how the cake association works.

Try setting up your relationships in a single bindModel() call.
$this->Npo->bindmodel(array(
'hasOne' => array(
'NpoTemplate' => array(
'foreignKey' => false,
'conditions' => array(
'Npo.id = NpoTemplate.npoid'
)
),
'TemplateTheme' => array(
'foreignKey' => false,
'conditions' => array(
'NpoTemplate.template_theme_id = TemplateTheme.id'
)
)
)
));
$arrUserSite = $this->Npo->find('first', array(
'conditions' => array(
'Npo.address' => $user
)
));
You'll probably need to tweak the bindModel setup because I'm not 100% sure of your database structure. Good luck.

CakePhp: On the fly associations using a re-named Model field?

I'm trying to use on the fly associations to trim down the data I retrieve, but the model I'm using is associated to other models with a re-named field because I have 2 of the same models associated with it.
So, here's the model, say 'test', that has two 'user' fields, both related to the User model.
In the model:
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
),
'User_Watched' => array(
'className' => 'User',
'foreignKey' => 'user_id_watched'
)
);
When I retrieve data related to 'test', I want to only retrieve particular data linked to the 'User' and 'User_Watched' fields without any other nested information.
But when I do:
$this->User->unbindModel(array('hasMany' => array('something1', 'something2')), false);
then something1 and something2 data does not show up for the 'User' field of model 'test', but is still retrieved for the 'User_watched' field.
Can I not retrieve unwanted data for the 'User_watched' field?
Hope this makes sense... :)
KcYxA,
Containable behavior might help a lot in this case, as benjamin mentioned, your "find" queries would look like:
$this->User->find('first', array(
'conditions' => array('User.id' => $id),
'contain' => array('UserWatched')
));
In this case, you won't have to use unbindModel method. In this example, you'll get User and UserWatched data.
If you need only User data from "find", then tell Cake to "$this->User->contain();" so it won't go further then User model.
to use on the fly associations to trim
down the data I retrieve
Good idea.
'foreignKey' => 'user_id_watched'
should possibly be:
'foreignKey' => 'user_watched_id'.
Edit 1: At least this would make sense according to my current understanding. If user_id is a correct foreign key(FK), which cakephp uses to unbind the relations, but user_id_watched isn't, than your described behavior is explained.
Edit 2: The Containable behavior gives you another tool for controlling associated models.
Change $primaryKey in fly, run controller
Sample:
// Models
//....
class PreProductoDescripcion extends AppModel {
/**
* Primary key field
*
* #var string
*/
public $primaryKey = 'id_producto_descripcion';
//....
//....
}
class SenasaPedidosDetalles extends AppModel {
/**
* Display field
*
* #var string
*/
public $displayField = 'cod_tango';
public $belongsTo = array(
'SenasaPedidos' => array(
'className' => 'SenasaPedidos',
'foreignKey' => 'senasa_pedidos_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'PreProductoDescripcion' => array(
'className' => 'PreProductoDescripcion',
'foreignKey' => 'cod_tango',
//'conditions' => array('SenasaPedidosDetalles.cod_tango' => 'PreProductoDescripcion.codigo'),
'fields' => '',
'order' => ''
)
);
//....
#
// Controller Fly
//...
$this->SenasaPedidos->Behaviors->load('Containable');
$this->SenasaPedidos->SenasaPedidosDetalles->PreProductoDescripcion->primaryKey = 'codigo';
$datos = $this->SenasaPedidos->find(
'first', array(
'fields' => array( 'SenasaPedidos.*' ),
'conditions' => array( 'SenasaPedidos.id' => $id ),
'contain' => array(
'Usuarios' => array(
'fields' => array( 'Usuarios.apellido_nombre' )
),
'Clientes' => array(
'fields' => array( 'Clientes.razon_social' )
),
'Provincias' => array(
'fields' => array( 'Provincias.nombre' )
),
'Transportes' => array(
'fields' => array( 'Transportes.razon_social' )
),
'SenasaPedidosDetalles' => array(
'fields' => array( 'SenasaPedidosDetalles.*' ),
'PreProductoDescripcion' => array(
'fields' => array(
'PreProductoDescripcion.id_producto_descripcion',
'PreProductoDescripcion.descripcion'
)
)
),
)
));
