Searching data from associated models in CakePHP - cakephp

Question

I am using CakePHP 2.3.6. In my project, I have to search users using some values/data/parameter, which are in several tables, and the tables are associated.
The associations are :
in the model User.php :
public $hasMany=array('Education'=>array(
'className'=>'Education
'foreignKey'=>'user_id'
),
'Experience'=>array(
'className'=>'Experience',
'foreignKey'=>'user_id'
),
'Employment'=>array(
'className'=>'Employment',
'foreignKey'=>'user_id'
),
'ProfessionalQualification'=>array(
'className'=>'ProfessionalQualification',
'foreignKey'=>'user_id'
)
)
in the model Education.php :
public $belongsTo=array('User'=>array(
'className'=>'User',
'foreignKey'=>'user_id'
)
)
in the model Experience.php :
public $belongsTo=array('User'=>array(
'className'=>'User',
'foreignKey'=>'user_id'
)
)
in the model Employment.php :
public $belongsTo=array('User'=>array(
'className'=>'User',
'foreignKey'=>'user_id'
)
)
in the model ProfessionalQualification.php :
public $belongsTo=array('User'=>array(
'className'=>'User',
'foreignKey'=>'user_id'
)
)
Now, in the Search form (View/Users/search.ctp) :
echo $this->Form->create('User');
echo $this->Form->input('name',array('type'=>'text'));
echo $this->Form->input('username',array('type'=>'text'));
echo $this->Form->input('address',array('type'=>'textarea'));
echo $this->Form->input('phone',array('type'=>'tel'));
echo $this->Form->input('degree',array('type'=>'text'));
echo $this->Form->input('passing_year',array('type'=>'text'));
echo $this->Form->input('title',array('type'=>'text'));
echo $this->Form->input('title.description',array('type'=>'textarea'));
echo $this->Form->input('company',array('type'=>'text'));
echo $this->Form->input('company.description',array('type'=>'textarea'));
echo $this->Form->input('certificate',array('type'=>'text'));
echo $this->Form->input('certificate.description',array('type'=>'textarea'));
echo $this->Form->submit('Search');
echo $this->Form->end();
in the UsersController.php controller :
public function search(){
$this->set('title_for_layout','Search User');
if($this->request->is('post')){
$conditions=array();
$data=$this->request->data;
if(!empty($data['name']))
$conditions['name']="%".$data['name']."%";
if(!empty($data['username']))
$conditions['username']=$data['username'];
if(!empty($data['address']))
$conditions['address']='%'.$data['address'].'%';
if(!empty($data['phone']))
$conditions['phone']=$data['phone'];
if(!empty($data['degree']))
$conditions['degree']="%".$data['degree']."%";
.
.
.
if(!empty($data)){
$users=$this->User->find('all',array('conditions'=>$conditions));
if(!empty($users)){
$this->Session->setFlash("Searching Users Successful");
$this->set('users',$users);
}else
$this->Session->setFlash("No user found");
}else
$this->Session->setFlash("You didn't give any info to search for");
}
}
I thought it'd retrieve all data I am looking for, from all the associated tables, in an array. But, it gives an error :
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'degree' in 'where clause'
SQL Query: SELECT `User`.`id`, `User`.`name`, `User`.`username`, `User`.`phone`, `User`.`address`, `User`.`created`, `User`.`modified` FROM `db_name`.`users` AS `User` WHERE `degree` = 'M.Sc.'
Here, "degree" is from the table "Education".
Then, I used ContainableBehavior. In the User.php model :
public $actsAs=array('Containable');
In the UsersController.php :
$this->User->find('all',array('contain'=>array('Education'=>array(
'conditions'=>array('Education.institution ='=>"Institute 1")
),
'Employment'=>array(
'conditions'=>array('Employment.employer ='=>"Employer 1")
),
'ProfessionalQualification'=>array(
'conditions'=>array('ProfessionalQualification.certificate ='=>"Certificate 1")
),
'Experience'=>array(
'conditions'=>array('Experience.title ='=>"Title 1")
)
)
)
);
When I use this, the result array is :
array(
(int) 0 => array(
'User' => array(
'name' => 'Name 3',
'email' => 'user3#email.com',
'mobile' => '9325028505',
'id' => '4'
),
'Education' => array(),
'Employment' => array(),
'ProfessionalQualification' => array(),
'Experience' => array()
),
(int) 1 => array(
'User' => array(
'name' => 'Name 2',
'email' => 'user2#email.com',
'mobile' => '9082730572',
'id' => '3'
),
'Education' => array(),
'Employment' => array(),
'ProfessionalQualification' => array(),
'Experience' => array()
),
(int) 2 => array(
'User' => array(
'name' => 'Name 1',
'email' => 'user1#email.com',
'mobile' => '715414918934',
'id' => '2'
),
'Education' => array(

)
),
'Employment' => array(
(int) 0 => array(
'id' => '1',
'applicant_id' => '2',
'employer' => 'Employer 1',
'position_held' => 'Position 1',

'created' => '2014-05-18 16:48:08',
'modified' => '2014-05-18 17:20:12'
)
),
'ProfessionalQualification' => array(
(int) 0 => array(
'id' => '1',
'applicant_id' => '2',
'name_of_certificate' => 'Certificate 1',
'institute' => 'Institute 1',
'from' => '2011-10-11',
'to' => '2012-09-11',
'location' => 'Local Ins.',
'created' => '2014-05-18 16:48:08',
'modified' => '2014-05-18 17:20:12'
)
),
'Experience' => array(
(int) 0 => array(
'id' => '1',
'applicant_id' => '2',
'title' => 'Title 1',
'institute' => 'Institute 1',
'training_year' => '2013',
'location' => 'Local Ins.',
'created' => '2014-05-18 16:48:08',
'modified' => '2014-05-18 17:20:12'
)
)
),
(int) 3 => array(
'User' => array(
'name' => 'Name 4',
'email' => 'user4#email.com',
'mobile' => '9082730572',
'id' => '5'
),
'Education' => array(),
'Employment' => array(),
'ProfessionalQualification' => array(),
'Experience' => array()
)
)
Here, notice, that I only need the 2 no. array, nothing else, but it gives me all data that are not relevant.
Can you please tell me where is the problem ? What should I do ? I guess, I have to explicitly give the table names in the form, on the specific fields, like : ModelName.0.field. What do you think?

try this
public function global_search() {
$condition = array(
'User.role' => array('U', 'P'),
'User.user_status' => array('active', 'lead', 'inactive')
);
if ($this->request->is('post') || $this->request->is('put')) {
$or = array(
'PersonalInformation.first_name' => $this->request->data['User']['first_name'],
'PersonalInformation.last_name' => $this->request->data['User']['last_name'],
'PersonalInformation.primary_phone' => $this->request->data['User']['primary_phone'],
'PersonalInformation.dob' => $this->request->data['User']['dob'],
'User.email' => $this->request->data['User']['email'],
);
//==========This Function allow remove blank element from array=========//
$or = array_filter($or);
//=====End============//
$condition = array(
'User.role' => array('U', 'P'),
'User.user_status' => array('active', 'lead', 'inactive'),
'OR' => $or
);
$data = $this->User->find('first', array(
'conditions' => $condition)
);
// pr($data); exit;
$this->set('allusers', $data);
}
$data = $this->User->find('all', array(

//pr($data); exit;
$this->set('allusers', $data);
$this->layout = 'admin';
