Cakephp: Find order by related model

Cakephp: Find order by related model - cakephp

I have two models: Event and Date. A Event hasMany Date. I want to order the events by the most recent dates. For example:
[0] => Array
(
[Event] => Array
(
[id] => 1
[name] => Event 1
)
[Date] => Array
(
[0] => Array
(
[id] => 1
[date] => 2015-02-05
[start_time] => 06:00:00
[end_time] => 17:00:00
[evento_id] => 1
)
[1] => Array
(
[id] => 2
[date] => 2015-02-06
[start_time] => 06:00:00
[end_time] => 17:00:00
[evento_id] => 1
)
)
)
[1] => Array
(
[Event] => Array
(
[id] => 2
[name] => Event 2
)
[Date] => Array
(
[0] => Array
(
[id] => 3
[date] => 2015-02-11
[start_time] => 06:00:00
[end_time] => 17:00:00
[event_id] => 2
)
)
)
[2] => Array
(
[Event] => Array
(
[id] => 3
[name] => Event 3
)
[Date] => Array
(
[0] => Array
(
[id] => 5
[date] => 2015-02-02
[start_time] => 06:00:00
[end_time] => 17:00:00
[event_id] => 3
)
[1] => Array
(
[id] => 6
[date] => 2015-02-03
[start_time] => 06:00:00
[end_time] => 17:00:00
[event_id] => 3
)
)
)
So, the order I want to retrieve the events are: Event 3, Event 1, Event 2.
This is how I'm calling the find method:
$this->Event->find('all', array('contain' => array('Date' => array('conditions' => array('Date.date >=' => date('Y-m-d'))))));
It's possible to do that with Cakephp find method? Thanks.

Something like this should do it
$this->Event->find('all', array(
'contain' => array(
'Date' => array(
'conditions' => array('
Date.date >=' => date('Y-m-d')
)
)
),
order => array(
'COUNT(Date.id)' => 'DESC'
)
));

group after order

In cakephp 2 I want to group table after descending order
always returned the first record of table
but I want returned last record by ordering
my data, code and result in here:
My data in table:
Code in controller:
$books = $this->Book->find('all', array(
'order' => array('age' => 'DESC'),
'group' => 'name'
));
print_r($books);
Result after the code above:
Array
(
[0] => Array
(
[Book] => Array
(
[id] => 1
[name] => ramin
[family] => zardoshti
[age] => 32
[city] => semnan
)
)
[1] => Array
(
[Book] => Array
(
[id] => 2
[name] => esmaeil
[family] => seydi
[age] => 30
[city] => semnan
)
)
)
But I want this result:
Array
(
[0] => Array
(
[Book] => Array
(
[id] => 1
[name] => ramin
[family] => zardoshti
[age] => 42
[city] => tehran
)
)
[1] => Array
(
[Book] => Array
(
[id] => 2
[name] => esmaeil
[family] => seydi
[age] => 30
[city] => semnan
)
)
)

Add a virtual field on the fly to your Book model
$this->Book->virtualFields = array(
'max_age' => sprintf('max(%s.age)', $this->Book->alias)
);
$books = $this->Book->find('all', array(
'order' => array('age' => 'DESC'),
'group' => 'name'
));
print_r($books);
The virtual field will help to get the rows with the maximum age value.
Your SQL query will look like :
SELECT
`Book`.`id`, `Book`.`name`, `Book`.`family`, `Book`.`age`,
`Book`.`city`, (max(`Book`.`age`)) AS `Book__max_age`
FROM
`test`.`books` AS `Book`
WHERE
1 = 1
GROUP BY
name
ORDER BY
`age` DESC

How to use pagination with custom query in cakephp

group is not working in CakePHP

I am running following query in CakePHP:
$options = array('conditions' => array('Patient.' . $this->Patient->primaryKey => $id),array('recursive'=>2,'group'=>array('group_id')));
$this->set('patient', $this->Patient->PatientTest->find('all', $options));
But my group is not working as needed. It gives me output as follows:
Array
(
[0] => Array
(
[PatientTest] => Array
(
[patient_id] => 2
[test_id] => 1
[date] => 2014-03-27 17:44:17
[result] => 55
[group_id] => 1
)
[Patient] => Array
(
[id] => 2
[name] => Test Patient
[age] => 44
[gender] => 0
[email] => emailid#gmail.com
[contact] => 789654123
[date] => 0000-00-00 00:00:00
)
[Test] => Array
(
[id] => 1
[name] => Hb
[group_id] => 1
[normal] => 12 - 16 gma%
)
[Group] => Array
(
[id] => 1
[name] => Haematology
)
)
[1] => Array
(
[PatientTest] => Array
(
[patient_id] => 2
[test_id] => 2
[date] => 2014-03-27 17:44:17
[result] => 55
[group_id] => 1
)
[Patient] => Array
(
[id] => 2
[name] => Test Patient
[age] => 44
[gender] => 0
[email] => emailid#gmail.com
[contact] => 789654123
[date] => 0000-00-00 00:00:00
)
[Test] => Array
(
[id] => 2
[name] => PCV
[group_id] => 1
[normal] => 35-50%
)
[Group] => Array
(
[id] => 1
[name] => Haematology
)
)
)
I need them group by either group_id or by Group.id.
I am unable to find why it is not grouping.

not
$options = array
(
'conditions' => array
(
'Patient.' . $this->Patient->primaryKey => $id
),
array(
'recursive'=>2,
'group'=>array('group_id')
)
);
but
$options = array
(
'conditions' => array
(
'Patient.' . $this->Patient->primaryKey => $id
),
'recursive'=>2,
'group'=>array('group_id')
);
recursive, conditions and group are at the same level

Simple and sweet code :
$groupBy = 'Patient.group_id';
$options = array (
'conditions' => array
(
'Patient.' . $this->Patient->primaryKey => $id
),
'group'=>array($groupBy)
);

Cakephp 2.0 weird array_merge error when using contain

Solved it, I had an error in my contain. Stupid one.
'User' => array('Profile' => array('fields' => 'image_thumb_small')),
Should have been:
'User' => array('Profile' => array('fields' => array('image_thumb_small'))),

Deep association relating to top-level model?

Use the Linkable Behavior https://github.com/Terr/linkable
$this->Kin->find('all', array(
'link' => array(
'Species' => array(
'GrowthStage' => array(
'KinGrowthStage' => array(
'conditions' => 'Kin.id = KinGrowthStage.kin_id',
)
)
)
),
'order' => 'GrowthStage.order ASC'
));
