I have theCelebrant andCelebration models where aCelebrant has NCelebration. I am populating an input select in view of Celebration add that lists all registered Celebrant. Until then all right, the problem is that when you make the form submission the value of the select is coming as the number of select the viewing position, and I would like to come Celebrant ID.
Here's what I did:
CelebrationsController
$this->set('celebrants', $this->Celebration->Celebrant->find('list'));
view/Celebrations/add
echo $this->Form->input('celebrant_id', array('type' => 'select', 'label'=>'Celebrante', 'options' => $celebrants, 'empty' => __( 'Selecione um Celebrante' )));
model/Celebrant
var $hasMany = array(
'Celebration' => array(
'className' => 'Celebration',
'foreignKey' => 'celebrant_id'
)
);
model/Celebration
var $belongsTo = array(
'Celebrant' => array(
'className' => 'Celebrant',
'foreignKey' => 'celebrant_id'
)
);

I am having a strange behavior which I do not understand with my cakephp 2.
In my Model 'Study' I have a has many relation:
class Study extends AppModel {
public $hasOne = array(
'SubjectFilter' => array(
'className' => 'Subject_filter',
'dependent' => true
)
);
public $hasMany = array(
'ExecutedStudyTable' => array(
'className' => 'ExecutedStudyTable',
'foreignKey' =>'study_id',
'dependent' => true,
),
);
The ExecutedtStudyTable Model looks like this:
class ExecutedStudyTable extends AppModel {
public $belongsTo= array(
'Study' => array(
'className' => 'Study',
'foreignKey' => 'study_id'
),
'User' => array(
'className' => 'User',
'foreignKey' => false,
'conditions' => array('ExecutedStudyTable.user_id = User.id')
)
);
}
When retrieving data everything looks good until I try to do this:
$studies = $this -> Study -> find('all',array(
'conditions' => array(
'Study.user_id' => $cId,
'OR'=>array(
array('Study.state'=>'active'),
array('Study.state'=>'rehearsal')
),
'SubjectFilter.studyCode'=>null,
'ExecutedStudyTable.user_id'=>$user
)
));
I get this error: Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'ExecutedStudyTable.user_id' in 'where clause'
Cakephp builds this query like this:
SELECT `Study`.`id`, `Study`.`user_id`, `Study`.`created`, `Study`.`modified`, `Study`.`started`, `Study`.`completed`, `Study`.`title`, `Study`.`description`, `Study`.`numberParticipants`, `Study`.`state`, `User`.`id`, `User`.`username`, `User`.`password`, `User`.`role`, `User`.`firstName`, `User`.`familyName`, `User`.`email`, `User`.`addressStreet`, `User`.`addressCity`, `User`.`addressZip`, `User`.`phone1`, `User`.`phone2`, `User`.`created`, `User`.`modified`, `User`.`passwordResetCode`, `User`.`passwordResetDate`, `User`.`sendUsernameDate`, `SubjectFilter`.`id`, `SubjectFilter`.`study_id`, `SubjectFilter`.`m`, `SubjectFilter`.`f`, `SubjectFilter`.`age18_24`, `SubjectFilter`.`age25_34`, `SubjectFilter`.`age35_44`, `SubjectFilter`.`age45_54`, `SubjectFilter`.`age55plus`, `SubjectFilter`.`studyCode` FROM `eyevido`.`studies` AS `Study` LEFT JOIN `eyevido`.`users` AS `User` ON (`Study`.`user_id` = `User`.`id`) LEFT JOIN `eyevido`.`subject_filters` AS `SubjectFilter` ON (`SubjectFilter`.`study_id` = `Study`.`id`) WHERE `Study`.`user_id` = 1402402538 AND ((`Study`.`state` = 'active') OR (`Study`.`state` = 'rehearsal')) AND `SubjectFilter`.`studyCode` IS NULL AND `ExecutedStudyTable`.`user_id` = 1130451831
The ExecutedStudyTable is not joined like the SubjectFilter and no alias is defined for the table. Why is this working correctly on the hasOne relation and not on the hasMany? Where do I make the mistake?
I appreciate your replies
If you want to filter a model by associated model's field, one way is by Joining tables.
Note: Mention proper table name for model ExecutedStudyTable. Also mention the join condition between two tables.
$studies = $this->Study->find('all',array(
'fields' => array('Study.*'),
'joins' => array(
array('table' => 'executed_study_table', // Table name
'alias' => 'ExecutedStudyTable',
'type' => 'INNER',
'conditions' => array(
'ExecutedStudyTable.<field name> = Study.<field>', // Mention join condition here
)
)
),
'conditions' => array(
'Study.user_id' => $cId,
'OR'=>array(
array('Study.state'=>'active'),
array('Study.state'=>'rehearsal')
),
'SubjectFilter.studyCode' => null,
'ExecutedStudyTable.user_id' => $user
),
'recursive' => -1
));
public $hasOne = array(
'Subscriber' => array(
'className' => 'Subscriber',
'foreignKey' => 'UserID',
'conditions' => array(
'Subscriber.end_date >=' => date('Y-m-d')
),
));
Here date('Y-m-d') gives html parse error. Even echo and print is not working in model file.
My aim is to get data from all subscribed users table till current date.
You can try like this,
public $hasOne = array(
'Subscriber' => array(
'className' => 'Subscriber',
'foreignKey' => 'UserID',
'conditions' => array(
'Subscriber.end_date >= date("Y-m-d")'
),
));
It will work as per your requirement
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!!
I have 3 tables: users, specialities, specialities_users.
User HABTM Speciality
Speciality HABTM User
SpecialitiesUser belongsTo Speciality,User
I have also model SpecialitiesUser.
When I want to get specialities for given user I can do it through
SpecialitiesUser->find('all' array('conditions' => array('user_id' => $given_user_id));
Now I want to get all specialities that user NOT belongs to. How I can do this in Cake?
The $other_specialities variable in the following code should be what you want:
$the_users_specialities = $this->SpecialitiesUser->find('list', array(
'conditions' => array(
'SpecialitiesUser.user_id' => $given_user_id
),
'fields' => 'SpecialitiesUser.speciality_id'
));
$other_specialities = $this->Speciality->find('all', array(
'conditions' => array(
'NOT' => array(
'Speciality.id' => $the_users_specialities
)
)
));
UPDATE: This is how to do it using a single query:
$db = $this->Speciality->getDataSource();
$sub_query = $db->buildStatement(
array(
'fields' => array('`SpecialitiesUser`.`speciality_id`'),
'table' => $db->fullTableName($this->SpecialitiesUser),
'alias' => 'SpecialitiesUser',
'conditions' => array('`SpecialitiesUser`.`user_id`' => $given_user_id),
),
$this->Speciality
);
$other_specialities = $this->Speciality->find('all', array(
'conditions' => array(
$db->expression('`Speciality`.`id` NOT IN (' . $sub_query . ')')
)
));
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'
)
)
),
)
