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,

$joins = array(

),

I have a HABTM relationship of Students and Subjects. I simply want to display all the subjects associated with a student without repetition of student details. I dont want the student details to keep repeating in the data output. How do I get the student details as shown below to output once and then all the subjects associated with this student to output?
Group didnt work. I didnt see the answer in the docs but I am sure this is a simple task to do.

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,

),
'Referral' => array(

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') ,

$st = $this->Paginator->paginate('Student');
I have 3 models: messages, forums and users
A forum may have several messages and each message has posted by one user.
I would like to have in my forum model all messages and their owner.
So, in my Forum.php (model), I write:
public $belongsTo=array(
'User' => array(
'className' => 'User',
'foreignKey'=>'id_user'
),
);
public $hasMany=array(
'Message' => array(
'className' => 'Message',
'foreignKey'=>'id_forum'
),
);
and in my Message.php (model) :
public $belongsTo=array(
'User' => array(
'className' => 'User',
'foreignKey'=>'id_user'
),
);
With "debug($this->Forum->find('all'));", I get :
array(
(int) 0 => array(
'Forum' => array(
'id' => '3',
'titre' => 'rooo',
'message' => 'tooo',
'id_user' => '2',
'date_create' => '2014-07-20 17:24:07'
),
'User' => array(
'password' => '*****',
'id' => '2',
'username' => 'member',
'date_sign' => '2014-07-04 11:34:52'
),
'Message' => array(
(int) 0 => array(
'id' => '5',
'message' => 'hi',
'id_user' => '3',
'id_forum' => '3',
'date_add' => '2014-07-20 18:53:51'
)
)
)
)
But with "debug($this->Message->find('all'));", I get :
array(
(int) 0 => array(
'Message' => array(
'id' => '5',
'message' => 'hi',
'id_user' => '3',
'id_forum' => '3',
'date_add' => '2014-07-20 18:53:51'
),
'User' => array(
'password' => '*****',
'id' => '3',
'username' => 'membre2',
'date_sign' => '2014-07-20 18:26:41'
)
)
)
I don't understand why I don't get my user informations on my 1st model but it's working in the 2nd.
Thanks for helping.
You need to set recursive property of Forum modal to 2
$this->Forum->recursive=2;

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',

),
'StoryChapter' => array(

(int) 1 => array(
'Story' => array(

'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' => ''
),
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.
