cant paginate with containable - php

In cakephp I can't get paginate to work with containable.
I followed the docs and I can't get it to work with just 2 tables. Instead I get every associated table.
I get this error as well:
Notice (8): Indirect modification of overloaded property StudentsController::$paginate has no effect
The code works fine with a find all.
http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html#using-containable
$this->Student->Behaviors->load('Containable');
$this->paginate['Student'] = array(
'conditions' => array( 'student_inactive' => false,'Student.student_enq' => true ),
'limit'=>10,
'fields' => array('Student.id,last_name,first_name') ,
'contain' => array('Guardian' => array(
'fields' => array('id', 'guardian_email', 'guardian_first_name', 'guardian_last_name' ))) ,
'order' => 'Student.id'
);
$st = $this->paginate('Student');
array(
(int) 0 => array(
'Student' => array(
'id' => '233',
'student_inactive' => false,
'student_enq' => false,
'student_unallocated' => false,
'first_name' => 'Aadil',
.....
),
'TutoringType' => array(
'id' => '1',
'value' => 'Individual Tuition'
),
'Referral' => array(
'id' => '1',
'title' => 'Google - Organic',
'details' => ''
),

Try with -
$this->Paginator->settings = array(
'conditions' => array( 'student_inactive' => false,'Student.student_enq' => true ),
'limit'=>10,
'fields' => array('Student.id,last_name,first_name') ,
'contain' => array('Guardian' => array(
'fields' => array('id', 'guardian_email', 'guardian_first_name', 'guardian_last_name' ))) ,
'order' => 'Student.id'
);
$st = $this->Paginator->paginate('Student');

cant join tables HABTM and many to one ,cakephp

I cant use a join to get the required data from the table relationship of
Student HABTM Subject, and
Guardian 1 to many Student
Without giving all the code,my find gets the required data but it adds another table (AvailabilityForStudent)which has a HABTM relationship with Student, along with other fields. I simply get too much data.
I have to add Guardian2 to the Guardian table to avoid a conflict which i dont understand.
What is the correct join to display data from 3 tables only?
$students = $this->find('all', array(
'joins'=>$joins,
'conditions' => $conditions,
'fields'=> $fields,
'order'=>$order,
));
$joins = array(
array('table' => 'students_subjects',

'conditions' => array(
'Student.id=StudentsSubject.student_id',
)
),
array('table' => 'subjects',
'alias' => 'Subject',
'type' => 'LEFT',
'conditions' => array(
'StudentsSubject.subject_id=Subject.id',
)
),
array('table' => 'guardians',
'alias' => 'Guardian2',
'type' => 'LEFT',
'conditions' => array(

)
),

Cakephp: How to get data with specific fields on associated model

I'm using cakephp framework. I have two tables on my DB, courses and modules table. Those tables are related, courses has many modules. Basically I want to get data on courses and on modules but with specific fields. I want to get just the id and the title of the course and the id and the title of the module.
This code:
$courses_taken = $this->Course->find('all', array(
'conditions' => array('Course.id' => $course_id_list),
'fields' => array('Course.id', 'Course.title')
));
gives me:
array(
(int) 0 => array(
'Course' => array(
'id' => '1',
'title' => 'course 1'
),
'Module' => array(
(int) 0 => array(
'id' => '1',
'course_id' => '1',
'title' => 'module 1',
'image' => null,
'content' => 'Lorem ipsum',
'voice_over' => null,
'created' => '2014-09-03 14:02:25',
'modified' => '2014-09-03 14:02:28'
),
(int) 1 => array(
'id' => '2',
'course_id' => '1',
'title' => 'module 2',
'image' => null,
'content' => 'Sasdas',
'voice_over' => null,
'created' => null,
'modified' => null
)
)
),
(int) 1 => array(
'Course' => array(
'id' => '2',
'title' => 'course 2'
),
'Module' => array()
)
)
But I wanna select a specific field for module as well so I tried this code:
$courses_taken = $this->Course->find('all', array(
'conditions' => array('Course.id' => $course_id_list),
'fields' => array('Course.id', 'Course.title', 'Module.id', 'Module.title')
));
but gives me an error: Column not found: 1054 Unknown column 'Module.id' in 'field list'.
Please help me guys thanks.
Got the answer, To make sgt's answer work, $actsAs property should be added in Course model. Reference : http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html
Either you use some behavior like Containable and your find() will look like this :
$courses_taken = $this->Course->find('all', array(
'conditions' => array('Course.id' => $course_id_list),
'fields' => array('Course.id', 'Course.title'),
'contain' => array(
'Module' => array(
'fields' => array('Module.id', 'Module.title'),
),
),
));
try this -
$courses_taken = $this->Course->find('all', array(
'conditions' => array('Course.id' => $course_id_list),
'fields' => array('Course.id', 'Course.title'),
'contain' => array('Module.id', 'Module.title')
));

Order multidimentional array with cakephp find all

I have Story related to a Chapter with a many to many relation
I have a StoryChapter Model .
I have this find all stories result :
array(
(int) 0 => array(
'Story' => array(
'id' => '111',
'title' => 'First Story',
'question' => 'What do you want ?',
'description' => 'ezrsrfgq ergtqergq',
'date' => '2014-06-10',
'image' => '/uploads/stories/111.jpg',
'created' => '2014-06-10 07:51:35',
'modified' => '2014-06-13 12:45:43',
'created_by' => '1',
'original' => null,
'tags' => ''
),
'StoryChapter' => array(
(int) 0 => array(
'id' => '110',
'story_id' => '111',
'chapter_id' => '81',
'chapter_title' => 'Second Chapter',
'created' => '2014-06-11 00:00:00'
),
(int) 1 => array(
'id' => '109',
'story_id' => '111',
'chapter_id' => '80',
'chapter_title' => 'First Chapter',
'created' => '2014-06-13 00:00:00'
)
),
'StoryUser' => array(),
'StoryGroup' => array(),
'Favorite' => array(),
'Tag' => array()
),
(int) 1 => array(
'Story' => array(
'id' => '112',
'title' => 'Second Story',
'question' => 'What do you want ?',
'description' => 'edghs rthsghsx ghs rhsgrhsrtgh',
'date' => '2014-06-13',
'image' => '/uploads/stories/112.jpg',
'created' => '2014-06-13 07:43:18',
'modified' => '2014-06-13 07:43:18',
'created_by' => '1',
'original' => null,
'tags' => ''
),
'StoryChapter' => array(),
'StoryUser' => array(),
'StoryGroup' => array(),
'Favorite' => array(),
'Tag' => array()
)
)
I want the find function to order only the StoryChapter by created desc without affecting the order of the found stories .
I hope you understand what I mean .
Thank you
I solved the problem by adding the order in the hasMany array in the Story model
public $hasMany = array(
'StoryChapter' => array(
'className' => 'StoryChapter',
'foreignKey' => 'story_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => 'created ASC',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
),

DISTINCT not working with hasMany cakephp

I want to apply DISTINCT query in cakephp 2+ it's working fine but when I BindModel with that model it's not working ?
Here is my code please check it..
$this->User->bindModel(
array(
'hasMany' => array(
'UserPreference' => array(
'className' => 'UserPreference',
'foreignKey' => 'user_id',
'fields' => 'UserPreference.notification_status',
'conditions' => array('UserPreference.notification_status' => 1),
)
)
)
);
$data = $this->User->find('all', array('conditions' => array('app_id NOT ' => '0', 'User.status' => 1), 'fields' => array('DISTINCT User.app_id')));
pr($data); die;
just because I once happened something like this I fix it changing this:
$this->User->bindModel(
array(
'hasMany' => array(
'UserPreference' => array(
'className' => 'UserPreference',
'foreignKey' => 'user_id',
'fields' => 'UserPreference.notification_status',
'conditions' => array('UserPreference.notification_status = 1'),
)
)
)
);

Using Containable behavior to filter results in Cakephp 2.2.4

I'm using containable behavior and the result of my find('all') is:
array(
(int) 0 => array(
'User' => array(
'id' => '106',
'email' => 'daje#daje.it',
'pwd' => '0433c024cb08be13000d59a347e640482843f46f177e95749dc6599c259617fd3491dcb940b47693cbbc7f65a2cc5ef62deca2e600c1be133ad54170f7d1fbd1',
'role_id' => '3',
'active' => '1'
),
'Lead' => array(
'id' => '6'
),
'Estimate' => array(
(int) 0 => array(
'lead_id' => '6',
'Estimate' => array(
(int) 0 => array(
'TOT_count' => '2'
)
)
)
)
)
)
I need to to count how many estimates there are in the lead.
The total (2) is correct, but i see nested 'Estimated' array, why ?
The result i would like to get is:
array(
(int) 0 => array(
'User' => array(
'id' => '106',
'email' => 'daje#daje.it',
'pwd' => '0433c024cb08be13000d59a347e640482843f46f177e95749dc6599c259617fd3491dcb940b47693cbbc7f65a2cc5ef62deca2e600c1be133ad54170f7d1fbd1',
'role_id' => '3',
'active' => '1'
),
'Lead' => array(
'id' => '6'
),
'Estimate' => array(
'TOT_count' => '2'
)
)
)
This is the find:
$options = array(
'contain' => array(
'User',
'Estimate' => array(
'fields' => 'COUNT(*) AS TOT_count'
)
),
'conditions' => array('Lead.id' => 6),
'fields' => 'User.*',
'limit' => 1
);
debug($this->Lead->find('all', $options));
How can i do it?
Thanks!
When you use a "custom" AS statement, in your case TOT_count, Cake will always put this in a result key called 0. You can avoid this by defining TOT_count as a virtualField in your model. That way it will be nested directly under the model name in your resultset.
Secondly, the lead_id is forcedly retrieved, because it is "needed" to make the join with the Lead model. It can not properly retrieve all the data without that piece of information there.
