cakephp pagination next and previous not showing - cakephp

Question

I am using cakephp 1.3 and i am receiving strange problem with pagination.I have imnplemented pagination for I have working pagination code in more than one controller .But my rest of the controller not showing next and previous button and numbers for pagination is working fine
I am using this code in my view
<?php
if(!empty($zipcodes)){
echo "<div class='pagination'>";
echo #$this->Paginator->prev('« Previous', null, null, array('class' => 'disabled'));
echo #$this->Paginator->numbers();
echo #$this->Paginator->next('Next »', null, null, array('class' => 'disabled'));
echo '<div style="float:right;padding:5px;color:#000">'.$this->Paginator->counter().'</div>';
echo "<div class='clear'></div>";
echo "</div>";
}
?>
And in my controller i have used pagination controller as i am paginating custom query results .I included pagination code in app_model.php.
My ontroller code is
var $paginate = array(
'Zipcode' => array('limit' => 5,
'order' => array('id' => 'desc'),
)
);
my query and operation
$tsql = " SELECT Zipcode.* ".
" FROM zipcodes AS Zipcode ".
" WHERE Zipcode.region_id=0 ";
$conditions = array(
'tsql'=>$tsql,
);
$tmp = $this->paginate('Zipcode',$conditions);
$this->set('zipcodes', $tmp);
can any one point out me what i am doing wrong.??And why pagination is working for only some controller .??? THanks in advance

Answer 1

First, change your paginate in the top of the controller. Remove Zipcode from it. It should just be:
var $paginate = array(
'limit' => 5,
'order' => array('Zipcode.id' => 'desc'),
);
Second, I am not sure what you are trying to accomplish with $tsql, but as far as I know, you cannot pass a SELECT statement as a condition. You need to write ORM specific conditions like this:
$this->paginate = array(
'conditions' => array('Zipcode.region_id' => 0),
);
Then to set zipcodes you can do this:
$this->set('zipcodes', $this->paginate('Zipcode'));
or this
$data = $this->paginate('Zipcode');
$this->set(compact('data'));
As a side note, echo #$this->Paginator->prev should be echo $this->Paginator->prev and all the # should be removed from those lines. That is poor coding practice. I'm not certain if you have the ignore in there for a reason, but it's bad.
