Cake PHP paginate multiple tables of one model-Collection of common programming errors
community, there is a problem with multiple tables which receive their entries of the same model “Post” on the same page. When clicking a paginator-number the app will change the page for both tables.
I tried it with dummy classes in the AppModel which should work but I get an error saying an internal error has occurred (error 500). I found out that there is a problem with the corresponding SQL-statement with a not found row.
In the AppModel:
class PostHood extends Post {
public $useTable = 'posts';
};
That code uses the table “cake_posts” of “class Post extends AppModel”. In the controller I tried to get the PostHood like following:
$this->paginate['PostHood'] = array(
'conditions' => array('OR' => array(stuff)),
'limit' => 5
);
$this->set('postsHood', $this->paginate('PostHood'));
In the view there is a foreach-loop using the $postsHood as $post. Maybe you have an idea, thanks in advance 🙂
EDIT 1: I got some error notices after changing the code. May be you have an idea what to do. Change of the AppModel:
class PostHood extends AppModel {
var $name = 'Post';
public $useTable = 'posts';
};
The Controller:
$this->loadModel('PostHood');
$this->paginate = array(
'conditions' => array('OR' =>
array(
array('AND' => array(
array('PostHood.ZIPCODE LIKE' => $userArea . '%'),
array('PostHood.ALTDATE >' => date("Y-m-d")),
array('PostHood.AGENT' => '0'),
array('PostHood.OWNER ' => $this->UserAuth->getUserId()),
array('PostHood.PARENTID' => '0'),
array('PostHood.ACCEPTED' => '0')
)), [MORE AND ARRAYS]
$this->set('postsHood', $this->paginate('PostHood'));
The corresponding error in the view:
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Post.DATE' in 'order clause'
SQL Query: SELECT PostHood.id, PostHood.B/S, PostHood.H, PostHood.CITY, PostHood.MARKET, PostHood.DATE, PostHood.ALTDATE, PostHood.TIME, PostHood.INCOME, PostHood.ZIPCODE, PostHood.ALIAS, PostHood.VEHICLE, PostHood.DELIVERYAREA, PostHood.SPACE, PostHood.STREET, PostHood.HOUSENUMBER, PostHood.NAME, PostHood.CART, PostHood.TEL, PostHood.OWNER, PostHood.created, PostHood.modified, PostHood.AGENT, PostHood.EXTRADATA, PostHood.PARENTID, PostHood.BRATED, PostHood.SRATED, PostHood.REQUESTED, PostHood.ACCEPTED FROM usr_web126986_4.cake_posts AS PostHood WHERE 1 = 1 ORDER BY Post.DATE asc LIMIT 5
Obviously Cake tries to fetch data with “PostHood” but the table “posts” which I actually want to use is listening to “Post.field”. How can I fix that? Thanks 🙂

You should try something like this:
$this->paginate = array( 'conditions' => array('OR' => array(stuff)), 'limit' => 5 ); $this->set('postsHood', $this->paginate('PostHood'));I am just curious as to why you want to structure your model extending another model.

Got it working with the great plugin DataTables. That overrides the cake-pagination and uses JSON to display the results.
In order to implement it into cake you need
1.) a cake component for interpreting sql-statements: https://github.com/cnizzdotcom/cakephp-datatable
2.) the plugin: http://www.datatables.net/index
3.) implementation:
$this->paginate = array( 'fields' => array('Model.field1', 'Model.field2'), 'conditions' => array( stuff ) ); $response = $this->DataTable->getResponse(); $this->set('response', $response); $this->set('_serialize','response'); $encode = json_encode($response); $this->set('dataTablesData', $encode);Then you can grab the data in the view.
