I'm using mongoDB in my symfony3 application, and I need to use setMaxResults and setFirstResult in my repository to paginate my results in my listing action. But I'm more used to use MySql as a database and I don't find how to do it in my cas.
I tried to use it as this :
$qb = $this->createQueryBuilder('DemoBundle:Entity');
$qb ->select('u');
$qb ->setMaxResults($max)
->setFirstResult($first);
But I have an error as followed :
Attempted to call an undefined method named "setMaxResults" of class
"Doctrine\ODM\MongoDB\Query\Builder
The full function is as like this :
public function search($data, $page = 0, $max = NULL, $getResult = true)
{
$qb = $this->createQueryBuilder('AresAPITournamentBundle:Tournament');
$query = isset($data['query']) && $data['query']?$data['query']:null;
$qb ->select('u');
if ($query) {
$qb
->andWhere('u.name like :query')
->setParameter('query', "%".$query."%")
;
}
if ($max) {
$qb ->setMaxResults($max)
->setFirstResult($page * $max)
;
} else {
$preparedQuery = $qb->getQuery();
}
return $getResult?$preparedQuery->execute():$preparedQuery;
}
I found the ressource in this tutorial.
How can I achieve this ?
Response was :
$qb ->limit($to)
->skip($from);

I have a plugin in my module that was working in Magento 2.3, but after upgrade to 2.4 i am getting the error
TypeError: Argument 2 passed to
..\Plugin\Controller\Checkout\Sidebar\RemoveItemPlugin::afterExecute()
must be an instance of Magento\Framework\App\Response\Http, instance
of Magento\Framework\Controller\Result\Json\Interceptor given
This is the code :
use Magento\Customer\CustomerData\SectionPoolInterface;
use Magento\Framework\Serialize\Serializer\Json;
class RemoveItemPlugin
{
public function __construct(
SectionPoolInterface $sectionPool,
Json $json
) {
$this->sectionPool = $sectionPool;
$this->json = $json;
}
public function afterExecute(
\Magento\Checkout\Controller\Sidebar\RemoveItem $subject,
\Magento\Framework\App\Response\Http $result
): \Magento\Framework\App\Response\Http {
/* Get Cart Items */
$sectionNames = "cart";
$sectionNames = $sectionNames ? array_unique(\explode(',', $sectionNames)) : null;
$forceNewSectionTimestamp = false;
$response = $this->sectionPool->getSectionsData($sectionNames, (bool)$forceNewSectionTimestamp);
/* Prepare Result */
$content = $this->json->unserialize($result->getContent());
$content['cartSection'] = $response;
$content = $this->json->serialize($content);
$result->setContent($content);
return $result;
}
}
I tried the answer in this question :
https://magento.stackexchange.com/questions/351344/magento-2-4-sidebar-removeitem-afterexecute-must-be-an-instance-of-magento-f
but once I change $result to be type resultInterface, I can no longer use $result->getContent() to return the cart json. Is there a way to do this with resultInterface?
I have a fairly large table with about 100000 records. If I don't set the limit in the repository
Repository:
public function paginateRequest() {
$query = $this->createQuery();
$result = $query->setLimit(1000)->execute();
//$result = $query->execute();
return $result;
}
/**
* action list
*
* #return void
*/
public function listAction() {
$this->view->assign('records', $this->leiRepository->paginateRequest());
//$this->view->assign('records', $this->leiRepository->findAll());
}
... the query and the page breaks although I'm using f:widget.paginate . As per the docs https://fluidtypo3.org/viewhelpers/fluid/master/Widget/PaginateViewHelper.html I was hoping that I can render only the itemsPerPage and 'parginate' through the records ...
List.hmtl
<f:if condition="{records}">
<f:widget.paginate objects="{records}" as="paginatedRecords" configuration="{itemsPerPage: 100, insertAbove: 0, insertBelow: 1, maximumNumberOfLinks: 10}">
<f:for each="{paginatedRecords}" as="record">
<tr>
<td><f:link.action action="show" pageUid="43" arguments="{record:record}"> {record.name}</f:link.action></td>
<td><f:link.action action="show" pageUid="43" arguments="{record:record}"> {record.lei}</f:link.action></td>
</tr>
</f:for>
</f:widget.paginate>
Model:
class Lei extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {
...
/**
* abc
*
* #lazy
* #var string
*/
protected $abc = '';
...
I use in TYPO3 9.5. The next function in repository:
public function paginated($page = 1, $size = 9){
$query = $this->createQuery();
$begin = ($page-1) * $size;
$query->setOffset($begin);
$query->setLimit($size);
return $query->execute();
}
And in the controller I am using arguments as parameter to send the page to load in a Rest action.
public function listRestAction()
{
$arguments = $this->request->getArguments();
$totalElements = $this->repository->total();
$pages = ceil($totalElements/9);
$next_page = '';
$prev_page = '';
#GET Page to load
if($arguments['page'] AND $arguments['page'] != ''){
$page_to_load = $arguments['page'];
} else {
$page_to_load = 1;
}
#Configuration of pagination
if($page_to_load == $pages){
$prev = $page_to_load - 1;
$prev_page = "http://example.com/rest/news/page/$prev";
} elseif($page_to_load == 1){
$next = $page_to_load + 1;
$next_page = "http://example.com/rest/news/page/$next";
} else {
$prev = $page_to_load - 1;
$prev_page = "http://example.com/rest/news/page/$prev";
$next = $page_to_load + 1;
$next_page = "http://example.com/rest/news/page/$next";
}
$jsonPreparedElements = array();
$jsonPreparedElements['info']['count'] = $totalElements;
$jsonPreparedElements['info']['pages'] = $pages;
$jsonPreparedElements['info']['next'] = $next_page;
$jsonPreparedElements['info']['prev'] = $prev_page;
$result = $this->repository->paginated($page_to_load);
$collection_parsed_results = array();
foreach ($result as $news) {
array_push($collection_parsed_results, $news->parsedArray());
}
$jsonPreparedElements['results'] = $collection_parsed_results;
$this->view->assign('value', $jsonPreparedElements);
}
The result of this, is a JSON like this:
{
"info": {
"count": 25,
"pages": 3,
"next": "",
"prev": "http://example.com/rest/news/page/2"
},
"results": [
{ ....}
] }
How large / complex are the objects you want to paginate through? If they have subobjects that you dont need in the list view, add #lazy annotation to those relations inside the model.
Due to this large amount of records, you should keep them as simple as possible in the list view. You can try to only give the result as array to the list view using $this->leiRepository->findAll()->toArray() or return only the raw result from your repository by adding true to execute(true).
You can also create an array of list items yourself in a foreach in the controller and only add the properties you really need inside the list.
If your problem is the performance, just use the default findAll()-Method.
The built-in defaultQuerySettings in \TYPO3\CMS\Extbase\Persistence\Repository set their offset and limit based on the Pagination widget, if not set otherwise.
If the performance issue persists, you may have to consider writing a custom query for your database request, that only requests the data your view actually displays. The process is described in the documentation: https://docs.typo3.org/typo3cms/ExtbaseFluidBook/6-Persistence/3-implement-individual-database-queries.html
Let's say I am building a search that finds all the teacher and got an input where the user can put in the search term. I tried reading the phalcon documentation but I only see things like binding parameters. I read the other thread about needing prepare statements do I need that in Phalcon as well?
And my function in the model would be something like this:
public function findTeachers($q, $userId, $isUser, $page, $limit, $sort)
{
$sql = 'SELECT id FROM tags WHERE name LIKE "%' . $q . '%"';
$result = new Resultset(null, $this,
$this->getReadConnection()->query($sql, array()));
$tagResult = $result->toArray();
$tagList = array();
foreach ($tagResult as $key => $value) {
$tagList[] = $value['id'];
....
}
}
My question is for the Phalcon framework is there any settings or formats I should code for this line $sql = 'SELECT id FROM tags WHERE name LIKE "%' . $q . '%"';
And also any general recommendation for preventing SQL Injection in PhalconPHP controllers and index would be appreciated.
For reference:
My controller:
public function searchAction()
{
$this->view->disable();
$q = $this->request->get("q");
$sort = $this->request->get("sort");
$searchUserModel = new SearchUsers();
$loginUser = $this->component->user->getSessionUser();
if (!$loginUser) {
$loginUser = new stdClass;
$loginUser->id = '';
}
$page = $this->request->get("page");
$limit = 2;
if (!$page){
$page = 1;
}
$list = $searchUserModel->findTeachers($q, $loginUser->id, ($loginUser->id)?true:false, $page, $limit, $sort);
if ($list){
$list['status'] = true;
}
echo json_encode($list);
}
My Ajax:
function(cb){
$.ajax({
url: '/search/search?q=' + mapObject.q + '&sort=<?php echo $sort;?>' + '&page=' + mapObject.page,
data:{},
success: function(res) {
//console.log(res);
var result = JSON.parse(res);
if (!result.status){
return cb(null, result.list);
}else{
return cb(null, []);
}
},
error: function(xhr, ajaxOptions, thrownError) {
cb(null, []);
}
});
with q being the user's search term.
You should bind the query parameter to avoid an SQL injection. From what I can remember Phalcon can be a bit funny with putting the '%' wildcard in the conditions value so I put them in the bind.
This would be better than just filtering the query.
$tags = Tags::find([
'conditions' => 'name LIKE :name:',
'bind' => [
'name' => "%" . $q . "%"
]
])
Phalcon\Filter is helpful when interacting with the database.
In your controller you can say, remove everything except letters and numbers from $q.
$q = $this->request->get("q");
$q = $this->filter->sanitize($q, 'alphanum');
The shortest way for requests:
$q = $this->request->get('q', 'alphanum');
Hi I am unable to use OR condation in my following Symfony findBy query.
$searchArrayTasks = array(
"name" => new \MongoRegex('/.*'.trim($_POST['keyword']).'.*/')
);
$documents = $dm->getRepository('WorkOrganisationBundle:Tasks')->findBy($searchArrayTasks)->sort($sortArray )->limit($limit)->skip($skip);
Can any one suggest please how to use OR condation in this query.Because i want to make a search basis on different parameters Like Name OR class OR Type.
Thanks Advance
This way (certainly in your Manager) is a bad practice.
Its purpose is for really dumb request.
2 things :
-Put your code in a Repository
-And code your query in sql or dql :
public function common($qb, $limit)
{
$qb->setMaxResults($limit)
->orderBy('task.id', 'DESC');
return $qb;
}
public function findByNameClassOrType($keyword, $limit)
{
$qb = $this->createQueryBuilder('task');
$qb->select('task')
->where('task.name LIKE ?', '%'.$keyword.'%')
->orWhere('task.class LIKE ?', '%'.$keyword.'%')
->orWhere('task.type LIKE ?', '%'.$keyword.'%');
$qb = $this->common($qb, $limit);
return $qb->getQuery()->getResult();
}
Use ? symbol to be sure that Doctrine escape your strings.
EDIT (mongodb) : with Mongo use addOr($expr)
$q = $doctrineOdm->createQueryBuilder('Work\OrganisationBundle\Document\Tasks');
$q->addOr($q->expr()->field('task.name')->equals($keyword));
$q->addOr($q->expr()->field('task.type')->equals($keyword));
$result = $q->getQuery()->execute();
For more informations see https://doctrine-mongodb-odm.readthedocs.org/en/latest/reference/query-builder-api.html
I want to update (replace) a subdocument within an array of all the documents, that have this specific embedded subdocument.
My sample content object is:
{
"_id" : ObjectId("51f289e5345f9d10090022ef"),
"title" : "This is a content",
"descriptors" : [
{
"_id" : ObjectId("51f289e5345f9d10090022f4"),
"name" : "This is a descriptor",
"type" : "This is a property"
},
{
"_id" : ObjectId("51f289e5345f9d10090022f0"),
"name" : "This is another descriptor",
"type" : "This is another property"
}
]
}
I want to find the object with a specific descriptor._id.
I want to replace the one subdocument with another one (respectivley with an updated version of the old object, but not necessarily with the same properties).
While this works well in RoboMongo / shell...
db.Content.update(
{
'descriptors._id': ObjectId("51f289e5345f9d10090022f4")
},
{
$set: {
'descriptors.$': {
"_id" : ObjectId("51f289e5345f9d10090022f4"),
"name" : "This is the updated descriptor",
"category" : "This is a new property"
}
}
},
{
'multi': true
})
...and with the plain php methods...
$descriptor = array();
$descriptor['_id'] = new \MongoID('51f289e5345f9d10090022f4');
$descriptor['name'] = 'This is the updated descriptor';
$descriptor['category'] = 'This is a new property';
$mongo = new \Mongo('mongodb://localhost:27017');
$database = $mongo->selectDB('MyDatabase');
$output = $database->selectCollection('Content')->update(
array('descriptors._id' => $descriptor['_id']),
array('$set' => array('descriptors.$' => $descriptor)),
array("multiple" => true)
);
...it doesn't work with Doctrine MongoDB ODM...
$descriptor = array();
$descriptor['_id'] = new \MongoID('51f289e5345f9d10090022f4');
$descriptor['name'] = 'This is the updated descriptor';
$descriptor['category'] = 'This is a new property';
$query = $dm->createQueryBuilder('Content')
->update()->multiple(true)
->field('descriptors._id')->equals($descriptor['_id'])
->field('descriptors.$')->set($descriptor)
->getQuery()->execute();
...because it fails with the following error:
Notice: Undefined offset: 2 in C:\MyProject\vendor\doctrine\mongodb-odm\lib\Doctrine\ODM\MongoDB\Persisters\DocumentPersister.php line 998
So I assume, that Doctrine MongoDB ODM needs three parts in the dot-notation. The not so nice solution would be to iterate over the properties of the subdocument and set them manually.
$descriptor = array();
$descriptor['_id'] = new \MongoID('51f289e5345f9d10090022f4');
$descriptor['name'] = 'This is the updated descriptor';
$descriptor['category'] = 'This is a new property';
$query = $dm->createQueryBuilder('Content')
->update()->multiple(true)
->field('descriptors._id')->equals($descriptor['_id']);
foreach ($descriptor as $key => $value) {
$query->field('descriptors.$.'.$key)->set($value);
}
$query->getQuery()->execute();
But this will only update existing and add new properties, but won't remove old/unnecessary properties from the subdocument.
Any ideas how to solve the problem:
with a simple query
while using Doctrine MongoDB ODM
without looping over the subdocument-array in php
I'm using:
Mongo-Server: 2.4.5
PHP: 5.4.16
PHP-Mongo-Driver: 1.4.1
Composer:
"php": ">=5.3.3",
"symfony/symfony": "2.3.*",
"doctrine/orm": ">=2.2.3,<2.4-dev",
"doctrine/doctrine-bundle": "1.2.*",
"doctrine/mongodb-odm": "1.0.*#dev",
"doctrine/mongodb-odm-bundle": "3.0.*#dev"
This was a bug in ODM and should be fixed in PR #661. Please take a look and ensure that the revised test satisfies your use case.
Until the next beta of ODM is tagged, this will only reside in the master branch; however, that should match your 1.0.*#dev version requirement.
You can do this thing but in a "not easy" way becuse when you use EmbedMany or ReferenceMany in Doctrine becames a Doctrine ArrayCollection objects that implemented the ArrayCollection contains() method with (as explained here) with the PHP in_array() method with the $strict parameter set to true... this way works with ReferenceMany but not with EmbedMany!
The concept is: ArrayCollection -> array -> ArrayCollection
In the definition of Document
...
/**
* #ODM\EmbedMany(targetDocument="EmbeddedElement")
*/
private $elements = array();
...
public function getElements() { return $this->elements; }
public function setElements($elements) { $this->elements = $elements; }
public function addElement(Element $element) { $this->elements[] = $element; }
public function setElement(Element $element, $index=0)
{
$elementsArray = $this->elements->toArray();
$elementsArray[$index] = $element;
$this->elements = new ArrayCollection($elementsArray);
}
public function removeElement(Element $element)
{
$index = array_search($element, $this->elements->toArray(), $strict=false);
if($index !== false)
$this->elements->remove($index);
}
public function removeElementByIndex($index) { $this->elements->remove($index); }
