How to stop Silverstripe SearchContext from throwing Version Table_Live error - search

Consider the following Silverstripe page class
<?php
class Page extends SiteTree{
static $has_many = array('OtherDataObjects' => 'DataObjectClass');
public function getSearchContext() {
$fields = new FieldSet(
new TextField('Title', 'Tour'),
new DropdownField('OtherDataObjects', 'Other Data Object', array('data', 'value')
);
$filters = array(
'Title' => new PartialMatchFilter('Title'),
'OtherDataObjects' => new PartialMatchFilter('OtherDataObjects.Title')
);
return new SearchContext(
'Page',
$fields,
$filters
);
}
}
Adding this search form to a front-end form and posting a search form always results in a [User Error] with a SQL error containing something like this at the end.
AND ("DataObjectClass_Live"."DataObjectClass_Live" LIKE 'title') ORDER BY "Sort" LIMIT 25 OFFSET 0 Table 'database DataObjectClass_Live' doesn't exist
My searchcontext search throws up an error each time I try to run a search on a has_many relationship. The versioned extension seems to be the culprit because it adds _live to all tables regardless whether the baseclass has the versioned extension or not I get the same error in SilverStripe versions 2.4.x and the latest 3.0.x versions.
Any help or pointers will be appreciated.

maybe try using an sqlQuery. something like
function SearchResults() {
$select = array('*');
$from = array('OtherDataObjects');
$where = array('OtherDataObjects:PartialMatch' => '%' . $data['Title'] . '%');
$sqlQuery = new SQLQuery($select, $from, $where);
$results = $sqlQuery->execute();
return $results;
}
$data['Title'] is to be the value from the search textbox

Silverstripe custom search into members dataobject

I have a little problem resolving getting SilverStripe 3.1 Fulltextsearchable running good for my usage. I retrieve some informations from Member dataobject and I create Links and Titles to show them on Page_search.ss template.
There is my code working but... bad search filtering :
public function results($data, $form){
$data = $_REQUEST;
$query = htmlspecialchars($data['Search'], ENT_QUOTES,'UTF-8');
$PageMembres = Member::get()->filter('NomOrganisme',$query);
$searchresults = new ArrayList();
foreach($PageMembres as $membre) {
if ($membre->Type==1) { $dir="repertoire-culturel/organismes-entreprises/details/"; }
if ($membre->Type==2) { $dir="repertoire-culturel/individus-artistes/details/"; }
$searchresults->push(
array( "Title" => $membre->NomOrganisme,
"link" => $membre->ID,
"Link" => Director::BaseURL().$dir.$membre->ID,
"URL" => $membre->ID,
)
);
}
if($searchresults){
$data['Results'] = $searchresults;
} else {
$data['Results'] = '';
}
$data['Title'] = 'Résultat(s) de recheche';
return $this->customise($data)->renderWith(array('Page_results','Page'));
}
So I that point, I need to change :
$PageMembres = Member::get()->filter('NomOrganisme',$query);
For a more complexe research like :
$PageMembres = DataObject::get("Member","MATCH (NomOrganisme,FirstName,Surname,Description) AGAINST ('$query' IN BOOLEAN MODE)");
What I have missed with the complexe query? Why It doesn't works?
Thanks for reply!
I think we can't use MATCH query on DataObject Member. There is my complexe working code that I use and works :
$PageMembres = Member::get()->where("
FirstName LIKE '%$query%' OR
Surname LIKE '%$query%' OR
Description LIKE '%$query%' OR
NomOrganisme LIKE '%$query%'");

How to integrate pagination in Kohana?

I am trying to integrate pagination in kohana, but don't know how to integrate it. Following is the controller function
public function action_index() {
//setup the model and view
$_users = Model::factory('users');
$us = $_users->get_users();
$view = View::factory('users/index')->bind('user_list', $us);
$this->template->set('content',$view);
}
How can i add pagination in this function?
I found some code for pagination but couldn't integrate it. This is the function i found
$this->pagination = new Pagination(array(
'base_url' => 'users/index/',
'uri_segment' => 'page',
'total_items' => count($items->get_item_count())
Please help me
EDIT:
I tried something like
public function action_index(){
$query = DB::select()->from('user');
// count number of users
$total_users = count($query);;
// set-up the pagination
$pagination = Pagination::factory(array(
'total_items' => $total_users,
'items_per_page' => 10, // this will override the default set in your config
));
// select rows using pagination's limit&offset
$users = $query->offset($pagination->offset)->limit($pagination->items_per_page)->execute();
$view = View::factory('users/index')->bind('user_list', $users)->bind('pagination', $pagination);
$this->template->set('content',$view);
}
Now no error found but pagination not showing up. Used shadowhand's pagination module suggested by #DanielThompson
I use shadowhand's pagination module which supports Kohana 3+, just make sure you grab the same branch as your Kohana version, then add it to your modules directory.
Update your application/bootstrap.php file:
Kohana::modules(array(
// ...
'pagination' => MODPATH.'pagination'
));
Copy modules/pagination/config/pagination.php to application/config/pagination.php
In your controller action (e.g. users):
// count number of users
$total_users = ORM::factory('User')->count_all();
// set-up the pagination
$pagination = Pagination::factory(array(
'total_items' => $total_users,
'items_per_page' => 10, // this will override the default set in your config
));
// get users using the pagination limit/offset
$users = ORM::factory('User')->offset($pagination->offset)->limit($pagination->items_per_page)->find_all();
// pass the users & pagination to the view
$this->view->bind('pagination', $pagination);
$this->view->bind('users', $users);
In your view:
// loop over users
foreach($users as $user) {
// ...
}
// display pagination view using
echo $pagination;
The module comes with two views: basic or floating which is set in the config file. You could also create a custom one for your application.

How to implement a pagination for a search module in Zend Framework 2?

I have a module Search in my ZF2 application. The user fills in a search form out and gets a list of courses.
Now I'm adding the pagination to the module. The paginator is basically working: I can retrieve data over it and the pagination is displayed correctly (pagelinks 1-7 for 70 found courses with the dafault setting 10 items per page).
But it's still not usable. When I click on a pagelink, the form POST data is lost. I know -- it cannot work the way, how I implemented it (see the code below). But I have no idea, how to do it correctly, in order to eep checking the form data and nonetheless be able to use pagination.
That is my code:
Table class Search\Model\CourseTable
class CourseTable {
...
// without pagination
// public function findAllByCriteria(CourseSearchInput $input) {
// with pagination
public function findAllByCriteria(CourseSearchInput $input, $pageNumber) {
...
$select = new Select();
$where = new Where();
$having = new Having();
...
// without pagination
// $resultSet = $this->tableGateway->selectWith($select);
// return $resultSet;
// with pagination
$adapter = new \MyNamespqce\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());
$paginator = new \Zend\Paginator\Paginator($adapter);
$paginator->setCurrentPageNumber($pageNumber);
return $paginator;
}
...
}
Search\Controller\SearchController
class SearchController extends AbstractActionController {
public function searchCoursesAction() {
$form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
$request = $this->getRequest();
if ($request->isPost()) {
$courseSearchInput = new CourseSearchInput();
$form->setInputFilter($courseSearchInput->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$courseSearchInput->exchangeArray($form->getData());
// without pagination
// $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
// with pagination
$page = $this->params()->fromRoute('page');
$paginator = $this->getCourseTable()->findAllByCriteria($courseSearchInput, $page);
} else {
$paginator = null;
}
} else {
$paginator = null;
}
return new ViewModel(array(
'form' => $form,
// without pagination
// 'courses' => $courses,
// with pagination
'paginator' => $paginator,
'cities' => ...
));
}
...
}
How to get it working?
I also have the same problem, and I have solved it. But this is not good way. May be the idea will help you.
I solved it as follow: (Search pagination for Zend tutorial album module)
I build two action in controller named "search" and "index".
Whenever the search form submitted, it always post the value to search action. Search action build the url with search parameters, and redirect to index to disply search result.
And when the pagination links clicked, then posted values are passed through url. So whenever index action ask for search parameters, it always get the values in same format.
I defined route as follows:
'album' => array(
'type' => 'segment',
'options' => array(
'route' => '/album[/:action][/:id][/page/:page][/order_by/:order_by][/:order][/search_by/:search_by]',
'constraints' => array(
'action' => '(?!\bpage\b)(?!\border_by\b)(?!\bsearch_by\b)[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
'page' => '[0-9]+',
'order_by' => '[a-zA-Z][a-zA-Z0-9_-]*',
'order' => 'ASC|DESC',
),
'defaults' => array(
'controller' => 'Album\Controller\Album',
'action' => 'index',
),
),
),
There is a parameter named "search_by", which will keep all search parameters as a json string. This is the point, which is not good I know, but have not find any other way yet.
"Search" action build this string as -
public function searchAction()
{
$request = $this->getRequest();
$url = 'index';
if ($request->isPost()) {
$formdata = (array) $request->getPost();
$search_data = array();
foreach ($formdata as $key => $value) {
if ($key != 'submit') {
if (!empty($value)) {
$search_data[$key] = $value;
}
}
}
if (!empty($search_data)) {
$search_by = json_encode($search_data);
$url .= '/search_by/' . $search_by;
}
}
$this->redirect()->toUrl($url);
}
And next index action decode the string, do necessary action, and also send the json string to view.
public function indexAction() {
$searchform = new AlbumSearchForm();
$searchform->get('submit')->setValue('Search');
$select = new Select();
$order_by = $this->params()->fromRoute('order_by') ?
$this->params()->fromRoute('order_by') : 'id';
$order = $this->params()->fromRoute('order') ?
$this->params()->fromRoute('order') : Select::ORDER_ASCENDING;
$page = $this->params()->fromRoute('page') ? (int) $this->params()->fromRoute('page') : 1;
$select->order($order_by . ' ' . $order);
$search_by = $this->params()->fromRoute('search_by') ?
$this->params()->fromRoute('search_by') : '';
$where = new \Zend\Db\Sql\Where();
$formdata = array();
if (!empty($search_by)) {
$formdata = (array) json_decode($search_by);
if (!empty($formdata['artist'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('artist', '%' . $formdata['artist'] . '%')
);
}
if (!empty($formdata['title'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('title', '%' . $formdata['title'] . '%')
);
}
}
if (!empty($where)) {
$select->where($where);
}
$album = $this->getAlbumTable()->fetchAll($select);
$totalRecord = $album->count();
$itemsPerPage = 2;
$album->current();
$paginator = new Paginator(new paginatorIterator($album));
$paginator->setCurrentPageNumber($page)
->setItemCountPerPage($itemsPerPage)
->setPageRange(7);
$searchform->setData($formdata);
return new ViewModel(array(
'search_by' => $search_by,
'order_by' => $order_by,
'order' => $order,
'page' => $page,
'paginator' => $paginator,
'pageAction' => 'album',
'form' => $searchform,
'totalRecord' => $totalRecord
));
}
All the sorting and paging url contain that string.
If you know all the searching paarameters before, then you can define that at route, and pass like the same way without json string. As I have to build a common search, I have build a single string.
Source code for "Album search" is available in git hub at https://github.com/tahmina8765/zf2_search_with_pagination_example.
Live Demo: http://zf2pagination.lifencolor.com/public/album
#Sam & #automatix in the question comments are both right. My suggestion (though I'm looking for a simpler alternative) is to construct a segment route, which covers all of the options that you're likely to need and start with a standard form POST request.
Then, after the request is validated, pass the form data to the paginationControl helper as follows:
$resultsView = new ViewModel(array(
'paginator' => $paginator,
'routeParams' => array_filter($form->getData())
));
Then, in your view template, set the route parameters in the paginationControl view helper:
<?php echo $this->paginationControl($paginator, 'Sliding', 'paginator/default',
array('routeParams' => $routeParams)
) ?>
I've used array_filter here because it's a really simple way of removing any element from the form data that's null, empty or so on. That way you don't pass in extra data that you don't need.

Search through related model in Yii

I have a problem with searching in Yii. I have two models: Teams and Workers. On website there is a page called 'Team Workers' where I want to display CGridView widget with searching that displays Workers from the team (team id is passed as a _GET parameter).
I did this in TeamsController:
public function actionWorkers($id)
{
$model = Teams::model()->findByPk($id);
$workers = Workers::model();
$workers->unsetAttributes();
if(isset($_GET['Workers']))
{
$_GET['Workers']['idTeam'] = $id;
$workers->attributes = $_GET['Workers'];
}
else {
$workers->attributes = array('idTeam' => $id);
}
$teamWorkers = $workers;
$this->render('workers', array(
'model' => $model,
'teamWorkers' => $teamWorkers
));
}
And in the view file:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'team-workers-grid',
'dataProvider'=>$teamWorkers->search(),
'filter' => $teamWorkers,
'columns'=>array(
'name',
'surname',
array(
'id' => 'idWorker',
'class' => 'CCheckBoxColumn',
'checked' => '$data->confirmer',
'selectableRows' => '2',
// 'headerTemplate' => '{item}'
)
),
)); ?>
I got the error:
CDbCommand nie zdołał wykonać instrukcji SQL: SQLSTATE[23000]: Integrity constraint
violation: 1052 Column 'idTeam' in where clause is ambiguous. The SQL statement
executed was: SELECT COUNT(DISTINCT `t`.`idWorker`) FROM `workers` `t` LEFT OUTER JOIN
`teams` `Team` ON (`t`.`idTeam`=`Team`.`idTeam`) WHERE ((idTeam=:ycp0) AND (Team.name
LIKE :ycp1))
When I dont set idTeam attribute - it works fine. It's pretty weird - at the regular CRUD admin page - idTeam attribute is passed and that works fine.
Hot to deal with it?
In Workers::search() you have something like
$criteria->compare('idTeam',$this->idTeam);
Change it to
$criteria->compare('t.idTeam',$this->idTeam);
i.e prefix sql attribute with t. if it is from current model or with relation name if from other table/model
Also instead of:
$workers->attributes = array('idTeam' => $id);
yould could keep it simpler with:
$workers->idTeam = $id;
You have defined the column idTeam in Team and Workers. By joining those tables you would have a duplicate ("ambiguous") column in the result. That's what the error message tells you.
To solve this you have to use an alias for one of the columns.

Kohana 3.1 Query Count & Pagination

I am getting my feet wet with Kohana but having trouble with pagination. i get the following error :
ErrorException [ Fatal Error ]: Class
'Pagination' not found
following the unoffical wiki I amended the bootstrap file to include this:
Kohana::modules(array( 'database' => MODPATH.'database', 'userguide' => MODPATH.'userguide', 'pagination' => MODPATH.'pagination', ))
but that didn't seem to help.
my second question is with regards to query count.... I am surprised there is no function like $query-count() unless i opt for ORM instead i find this solution a bit clunky given that a query count is a must for every pagination request:
$result['count'] = $pagination_query->select('COUNT("*") AS result_count')->execute()->get('result_count');
Any suggestions?
thank you very much
Kohana 3.1 does not come with the pagination module...
it must be downloaded from
https://github.com/kohana/pagination
then go to the class/kohana edit line 199 from ->uri to ->uri()
that does it
as to the query count....still searching.
hope this helps someone
There used to be a count_last_query() function in the Database class which provided the total results of the last query run as it would be without any limit or offset, but they pulled it from version 3.0.9. You can find the documentation of it here:
http://kohanaframework.org/3.0/guide/api/Database#count_last_query
I've actually built upon the code from that function to make my own count query function if you want to use that.
protected static function _pagedQuery($query) {
$sql = (string)$query;
if (stripos($sql, 'LIMIT') !== FALSE) {
// Remove LIMIT from the SQL
$sql = preg_replace('/\sLIMIT\s+[^a-z]+/i', ' ', $sql);
}
if (stripos($sql, 'OFFSET') !== FALSE) {
// Remove OFFSET from the SQL
$sql = preg_replace('/\sOFFSET\s+\d+/i', '', $sql);
}
if (stripos($sql, 'ORDER BY') !== FALSE) {
// Remove ORDER BY from the SQL
$sql = preg_replace('/\sORDER BY\s+`\w+`(\.`\w+`)?(\s+DESC|\s+ASC)?/i', '', $sql);
}
$db = Database::instance();
$result = $db->query(Database::SELECT, '
SELECT COUNT(*) AS ' . $db->quote_identifier('total_rows') . '
FROM (' . $sql . ') AS ' . $db->quote_table('counted_results'),
TRUE
);
return (int)$result->current()->total_rows;
}
