Hi,
I have developed a cake php application.
In this there are tables like students,placements,batches,companies
In placements table there is student_id,company_id and in students table there is batch_id column.
In placements index page i have applied jq grid. Here is the screen shot.
I want to give searching on student,company and batch. For this i have used containable behavior inside placements controller index function.
if( $this->params['url']['_search'] == 'true' ) /* For Searching*/
{
//pr($this->params);
$searchconditions = array();
if( isset($this->params['url']['studentname']) && !empty($this->params['url']['studentname']) )
{
array_push(&$searchconditions, array('Student.fullname LIKE' => $this->params['url']['studentname'] . '%'));
}
if( isset($this->params['url']['companyname']) && !empty($this->params['url']['companyname']) )
{
array_push(&$searchconditions, array('Company.name LIKE' => $this->params['url']['companyname'] . '%'));
}
if( isset($this->params['url']['batchname']) && !empty($this->params['url']['batchname']) )
{
array_push(&$searchconditions, array('Batch.name LIKE' => $this->params['url']['batchname'] . '%'));
}
$result = $this->Placement->find('all', array(
'fields' => array('id','student_id','company_id'),
'contain' => array(
'Student' => array(
'fields' => array('id','fullname','batch_id'),
'Batch' => array(
'fields'=> array('id','name')
)
),
'Company' => array(
'fields' => array('id','name')
)
),
'conditions' => $searchconditions,
'order' => $sort_range,
'limit' => $limit_range
));
}
else /* Default display*/
{
$result = $this->Placement->find('all', array(
'fields' => array('id','student_id','company_id'),
'contain' => array(
'Student' => array(
'fields' => array('id','fullname','batch_id'),
'Batch' => array(
'fields'=> array('id','name')
)
),
'Company' => array(
'fields' => array('id','name')
)
),
'order' => $sort_range,
'limit' => $limit_range
));
}
The grid is populated fine with student name , company name and batch name (if case). Searching is also working fine in case i searched by student name & company name but when i tried to search by batch name i get the following error:
Warning (512): SQL Error: 1054: Unknown column 'Batch.name' in 'where clause' [APP\vendors\cakephp\cake\libs\model\datasources\dbo_source.php, line 681]
Query: SELECT `Placement`.`id`, `Placement`.`student_id`, `Placement`.`company_id`, `Student`.`id`, `Student`.`fullname`, `Student`.`batch_id`, `Company`.`id`, `Company`.`name` FROM `placements` AS `Placement` LEFT JOIN `students` AS `Student` ON (`Placement`.`student_id` = `Student`.`id`) LEFT JOIN `companies` AS `Company` ON (`Placement`.`company_id` = `Company`.`id`) WHERE `Batch`.`name` LIKE 'df%' ORDER BY `Placement`.`id` asc LIMIT 0,10
I think the relation between student & batch is not working as can be seen from the query.
I am unable to figure out why it is behaving as such.
Please help me on this.
Thanks
