Retrieving related model's data in CakePHP - cakephp

Here is the database tables in question:
Companies:
____________________
| id | name |
____________________
| 1| Unimex|
| 2| Solomex|
Users:
________________________
| id | name | company_id
_________________________
| 1| John | 1
| 2| Ricky| 2
Events:
_____________________________________
| id | user_id | details | date|
_____________________________________
| 1| 1| null | 2014-04-01
| 2| 1| null | 2014-04-15
| 3| 2| null | 2013-04-01
What I would like to do is to retrieve events for a particular date based on company's id. What I have tried to do is the following:
$this->User->find('all',
array(
'conditions' => array(
'company_id' => CakeSession::read("Auth.User.company_id")
),
'contain' => array(
'Event' => array(
'conditions' => array(
'Event.date' => date("Y-m-d", $tomorrow)
)
)
)
));
but this retrieves all of the events for the company, the date condition is not being applied.
In the best case I would like to retrieve only the events for one company for a particular date. Otherwise I would get by with returning a list of users related to one company and their events for that particular date.
What would be the most efficient way to do this?
Any help or guidance is much appreciated.
Following are the relations between the tables:
Events:
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
));
Users:
var $belongsTo = array(
'Company' => array(
'className' => 'Company',
'foreignKey' => 'company_id',
'dependent' => false,
),
);
Here is the query that I get:
SELECT Event.id, Event.customer_id, Event.user_id, Event.project_id, Event.service_id, Event.date, Event.start_city, Event.material, Service.id, Service.company_id, Service.name, Service.service_nr, User.id, User.company_id, User.employee_nr, User.name, User.surname, User.email, User.password, User.role, Customer.id, Customer.company_id, Project.name, Project.description, Project.link_nr, Project.start_date, Project.finish_date, Project.project_nr FROM schedule.events AS Event LEFT JOIN schedule.services AS Service ON (Event.service_id = Service.id) LEFT JOIN schedule.users AS User ON (Event.user_id = User.id) LEFT JOIN schedule.customers AS Customer ON (Event.customer_id = Customer.id) LEFT JOIN schedule.projects AS Project ON (Event.Project_id = Project.id) WHERE 1 = 1
The problem right now is that the company id is not taken into concideration, and all of the events are being returned no matter what date it is.

I’ve tried this solution and it works for me.
I made all tables with small letters according to cake conventions like companies, events and users.
This is Event Model
class Event extends AppModel {
var $actsAs = array('Containable');
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
}
This is controller Event class
$tomorrow = '2013-04-01';
$this->Event->find('all',
array(
'conditions' => array(
'date' => date("Y-m-d", strtotime($tomorrow)),
),
'contain' => array(
'User' => array(
'conditions' => array(
'User.company_id' => CakeSession::read ('Auth.User.company_id')
)
)
)
));
This will give you
SELECT `Event`.`id`, `Event`.`user_id`, `Event`.`details`, `Event`.`date`, `User`.`id`, `User`.`name`, `User`.`company_id`
FROM `schedule`.`events` AS `Event`
LEFT JOIN `schedule`.`users` AS `User` ON (`Event`.`user_id` = `User`.`id` AND `User`.`company_id` = 2)
WHERE `date` = '2013-04-01'
I hope this will work for you. Thanks

try this code:
$this->Event->find('all',
array(
'conditions' => array(
'User.company_id' => CakeSession::read("Auth.User.company_id"),
'Event.date' => date("Y-m-d", $tomorrow)
),
'contain' => array('User')
));

How get data from Relationship tables

I have 2 table in my database that second(orders) table has foreign_key of primary key of first(books) table like these
Books
----+---------+-------------
id | slug | name |
----+---------+--------------
1 | math | mathematics |
----+---------+--------------
2 | physics | holidays |
-----------------------------
Orders
----+---------+-------+--------
id | book_id | count | price |
----+---------+-------+--------
1 | 2 | 12 | 100000 |
--------------------------------
I want result like below
result
----+---------+----------+----------+----------+------------------
id | book_id | slug | name | order_id | count | price |
----+---------+----------+----------+-----------------------------
1 | 2 | physics | holidays | 1 | 12 | 100000 |
------------------------------------------------------------------
I believe each product has a price. To that start with relating PRODUCT table to PRICE.
In cake this is done very easily:
in your Model (Product.php)
class Product extends AppModel{
public $hasMany = array('Price');
}
in Price.php
class Price extends AppModel{
public $hasBelongTo = array('Product');
}
in your controller if you query any of these Models the returned array will contain data from both models.
make the relationships as follow
Product.php
....
public $hasMany = array(
'Price' => array(
'className' => 'Price',
'foreignKey' => 'product_id',
'dependent' => true,
'conditions' => '',
'group' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
),
....
Price.php
.....
public $belongsTo = array(
'Product' => array(
'className' => 'Product',
'foreignKey' => 'product_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
....
then in your controller use this query
$this->Product->find('all',array('contain'=>array('Price')));

CakePHP How to get Photo from different table?

Above two table i want to join. But i am unable to join. Please help me.
After lots of research finally i got my answer. This code helps to other-
//$user_id=$this->Session->read('Auth.User.id');
$user_id=1;
$this->Friend->bindModel(
array('hasOne' => array(
'Gallery' => array(
'className' => 'Gallery',
'foreignKey' => FALSE,
'conditions' => array('Friend.friend_id=Gallery.user_id'),
'type' => 'LEFT'
)
)
)
);
$this->Friend->bindModel(array('belongsTo' => array('User' => array('className' => 'User', 'foreignKey' => 'friend_id', 'conditions'=>array('Friend.user_id'=>$user_id)))));
$data = $this->Friend->find('all');
pr($data);

Retrieving related model's data CakePHP

Here is the database tables in question:
Companies:
____________________
| id | name |
____________________
| 1| Unimex|
| 2| Solomex|
Users:
________________________
| id | name | company_id
_________________________
| 1| John | 1
| 2| Ricky| 2
Events:
_____________________________________
| id | user_id | details | date|
_____________________________________
| 1| 1| null | 2014-04-01
| 2| 1| null | 2014-04-15
| 3| 2| null | 2013-04-01
| 4| 1| null | 2014-04-02
What I would like to do is to retrieve a list of users(based on company's id) and their related events for a range of dates. What I have tried to do is the following:
$users = $this->User->find('all',
array(
'conditions' => array(
'company_id' => CakeSession::read("Auth.User.company_id")
),
'contain' => array(
'Event' => array(
'conditions' => array(
'Event.date >=' => $from,
'Event.date <=' => $to
)
)
)
)
);
This way I get the list of Users with their related events, but the $from and $to dates are not taken into consideration, meaning all of the events for a particular user are returned.
The relations are like following:
Event:
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
));
User:
var $hasMany = array(
'Event' => array(
'className' => 'Event',
'foreignKey' => 'user_id',
'dependent' => false,
)
);
var $belongsTo = array(
'Company' => array(
'className' => 'Company',
'foreignKey' => 'company_id',
'dependent' => false,
),
);
Company:
var $hasMany = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'company_id',
'dependent' => false
));
Any help or guidance is much appreciated.
Following are the two queries that are executed by cakePHP:
SELECT `User`.`id`, `User`.`company_id`, `User`.`name`, `User`.`surname`, `User`.`email`, `User`.`phone`, `Company`.`id`, `Company`.`name`, `Company`.`address` FROM `database`.`users` AS `User` LEFT JOIN `database`.`companies` AS `Company` ON (`User`.`company_id` = `Company`.`id`) WHERE `company_id` = 54
SELECT `Event`.`id`, `Event`.`customer_id`, `Event`.`user_id`,`Event`.`details`, `Event`.`hours`, `Event`.`minutes`, `Event`.`xhours`, `Event`.`xminutes`, `Event`.`assignment`, `Event`.`start_time` FROM `database`.`events` AS `Event` WHERE `Event`.`user_id` IN (124, 125, 126, 141, 143, 144, 147, 156)
So as you can see the date in the Event field conditions is not taken into consideration. If there is any other important information that I can provide, please, just let me know.
Moreover, I have just tried to retrieve only specific fields of the Event model, and that did not work as well. So basically the model is just contained as is, an no other parameter is applied.
Or maybe the model is not contained at all and the result I get is only because of the recursive being set to 1?
I don't see the error only as a suggestion
$users = $this->User->find('all',
array(
'contain' => array(
'Event' => array(
'conditions' => array(
'and' => array(
array(
'Event.date >=' => $from,
'Event.date <=' => $to
),
'company_id' => CakeSession::read("Auth.User.company_id")
)
)
)
)
)
);
The problem is that there was a typo. I always thought it has to be:
var $actAs = array('Containable');
But it actually had to be $actsAs.

Relationships not working correctly - cakePHP

I have relationships set up by the built in CakePHP build function. First, my tables:
assets
id | company_id | group_id | location_id | item_id | invoice_id | item_number | description | purchase_value | purchase_date | barcode | colour | picture | created | modified
repairs
id | company_id | asset_id | invoice_id | created | modified
My relationship in my asset model looks like this:
public $hasMany = array(
'Repair' => array(
'className' => 'Repair',
'foreignKey' => 'asset_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
And in my repair model, like this:
public $belongsTo = array(
'Asset' => array(
'className' => 'Asset',
'foreignKey' => 'asset_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
However, when I try to view an asset, it shows this error:
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Asset.asset_id' in 'field list'
SQL Query: SELECT `Asset`.`id`, `Asset`.`company_id`, `Asset`.`group_id`, `Asset`.`location_id`, `Asset`.`item_id`, `Asset`.`invoice_id`, `Asset`.`item_number`, `Asset`.`description`, `Asset`.`purchase_value`, `Asset`.`purchase_date`, `Asset`.`barcode`, `Asset`.`colour`, `Asset`.`picture`, `Asset`.`created`, `Asset`.`modified`, `Asset`.`asset_id` FROM `asset_register`.`assets` AS `Asset` WHERE `Asset`.`company_id` = 1 AND `Asset`.`asset_id` = (4)
Anyone know what the issue is?
EDIT TO UPDATE
My find statement is the plain CakePHP find statement.
$options = array('conditions' => array('Asset.' . $this->Asset->primaryKey => $id));
$this->Asset->recursive = 1;
$this->set('asset', $this->Asset->find('first', $options));
EDIT
Add this line to your asset model
public $primaryKey = 'id';
and make sure that $primaryKey is not defined somewhere else in the model.

cakephp 'contain' left joint does not use specified foreignKey for left join

On cakephp 2.1, I have two tables: qca belongs to employee via field emp_number on both tables.
qca model belongsTo : (pleae note foreignKey)
public $actsAs = array('Containable');
var $belongsTo = array('Dir',
'Employee' => array(
'className' => 'Employee',
'foreignKey' => 'emp_number')
);
employee model:
public $actsAs = array('Containable');
On my controller's find, i use 'contain' to retrieve employee info based on emp_number from qca table.
$hoursvalues = $this->Qca->find('all', array('conditions' => $conditions,
'fields' => array('Qca.emp_number', 'Sum(CASE WHEN Qca.qca_tipcode = 1 THEN 1 END) AS Qca__comps', 'Sum(qca_end - qca_start) as Qca__production', 'Sum(Qca.qca_durend) as Qca__idle'),
'contain' => array(
'Employee' => array(
'fields' => array('emp_number', 'emp_ape_pat', 'emp_ape_mat', 'emp_ape_mat'))),
'group' => array('Qca.emp_number'),
));
However, the executed sql sentence shows:
LEFT JOIN `devopm`.`employees` AS `Employee` ON (`Qca`.`emp_number` = `Employee`.`id`)
Whereas
Employee.id should be Employee.emp_number
This is the full sql sentence:
SELECT `Qca`.`emp_number`, Sum(CASE WHEN Qca.qca_tipcode = 1 THEN 1 END) AS Qca__comps, Sum(qca_end - qca_start) as Qca__production, Sum(`Qca`.`qca_durend`) as Qca__idle, `Employee`.`emp_number`, `Employee`.`emp_ape_pat`, `Employee`.`emp_ape_mat`, `Employee`.`id` FROM `devopm`.`qcas` AS `Qca` LEFT JOIN `devopm`.`employees` AS `Employee` ON (`Qca`.`emp_number` = `Employee`.`id`) WHERE `Qca`.`dir_id` = 63 AND FROM_UNIXTIME(`Qca`.`qca_start`, '%Y-%m-%d') >= '2012-07-18' AND FROM_UNIXTIME(`Qca`.`qca_start`, '%Y-%m-%d') <= '2012-07-18' GROUP BY `Qca`.`emp_number`
This results on null values returned for Employee:
array(
(int) 0 => array(
'Qca' => array(
'emp_number' => 'id3108',
'comps' => '2',
'production' => '7784',
'idle' => '529'
),
'Employee' => array(
'emp_ape_pat' => null,
'emp_ape_mat' => null,
'id' => null
)
),
Note: I have other instance of 'contain' working (one with default id = tableName.id). I'm wondering if the foreignKey on belongsTo ('foreignKey' => 'emp_number') is just not good for 'contain' to work?
Can you help?
Thank you so much.
(I found a workaround but slows down the query a great deal (it duplicates the left join and takes forever)
$joins = array(
array('table' => 'publication_numerations',
'alias' => 'PublicationNumeration',
'type' => 'LEFT',
'conditions' => array(
'Publication.id = PublicationNumeration.publication_id',
)
)
);
$this->Publication->find('all', array('joins' => $joins));
