I have solved this by overriding the paginate and paginateCount methods
in my Book model.
/**
* Overridden paginate
*/
function paginate($conditions, $fields, $order, $limit, $page = 1,
$recursive = null, $extra = array()) {
if( $this->searchCategories){
$this->bindModel(array('hasOne' => array(
'BooksCategory' => array(
'className' => 'BooksCategory',
'foreignKey' => false,
'type' => 'inner',
'conditions' => array('BooksCategory.book_id = Book.id',
'BooksCategory.category_id' => $this->categories )
)
)), false );
}
if( $this->searchAuthors ){
$this->bindModel(array( 'hasOne' => array(
'BooksAuthor',
'FilterAuthor' => array(
'className' => 'Author',
'foreignKey' => false,
'type' => 'inner',
'conditions' => array('FilterAuthor.id = BooksAuthor.author_id')
))));
}
return $this->find('all', array(
'conditions' => $conditions,
'fields' => $fields,
'order' => $order,
'limit' => $limit,
'page' => $page,
'recursive' => $recursive));
}
/**
* Overridden paginateCount method
*/
function paginateCount($conditions = null, $recursive = 0, $extra =
array()) {
if( $this->searchCategories){
$this->bindModel(array('hasOne' => array(
'BooksCategory' => array(
'className' => 'BooksCategory',
'foreignKey' => false,
'type' => 'inner',
'conditions' => array('BooksCategory.book_id = Book.id',
'BooksCategory.category_id' => $this->categories )
))), false );
}
if( $this->searchAuthors ){
$this->bindModel(array( 'hasOne' => array(
'BooksAuthor',
'FilterAuthor' => array(
'className' => 'Author',
'foreignKey' => false,
'conditions' => array('FilterAuthor.id = BooksAuthor.author_id')
))));
}
$records = $this->find('all', array(
'conditions' => $conditions,
'fields' => array( 'DISTINCT Book.id' ),
'recursive' => $recursive));
return count($records);
}
