I've been using Zend Framework for a few months now. So, my knowledge is pretty good but I'm not quite an expert yet. I am trying to use zend_lucene with zend_paginator and so far not successful. I am able to use zend_lucene and index data successfully by itself and able to do use zend_paginator when querying the database, but I can't seem to combine the two. Here is a sample of what I am doing:
try {
$searchresults = $index->find($lucenequery);
}
catch (Zend_Search_Lucene_Exception $e) {
echo "Unable {$e->getMessage()}";
}
$page = $this->_getParam('page',1);
$paginator = Zend_Paginator::factory($searchresults);
$paginator->setItemCountPerPage(20);
$paginator->setCurrentPageNumber($page);
$this->view->paginator = $paginator;
Is there a different step I need to do with lucene and zend_paginator? I am really uncertain. The result I get is that for the first page results display properly. But when I hit the second page or third my results are blank. So uncertain what might be wrong as I can't find docs or tutorials in using the two together. Any help would be greatly appreciated.
I think this may work with the iterator adapter:
public function searchAction() {
$index = Zend_Search_Lucene::open('/path/to/lucene');
$results = $index->find($this->_getParam('q'));
$paginator = Zend_Paginator::factory($results);
$paginator->setCurrentPageNumber($this->_getParam('page', 1));
$paginator->setItemCountPerPage(10);
$this->view->results = $paginator;
}
Perhaps the problem you are having is that $paginator doesn't know how many search results there are..
So you may need to do that manually:
$paginator->setDefaultPageRange($results->count());

im currently trying to sort all Childobjects i can get by their validity time.
my current code is not sorting anything:
$children = $this->productRepository->findByParent($product->getNumber());
foreach ($children as $child) {
//debug::debug($child->getvalidityPeriod());
$product->addChild($child);
}
As allready to see in the debug, $child->getvalidityPeriod() is there to get the needed info as integer. I thought, there must be a way to sort this object array by their validityPeriod, but how do i manage that? Do i need to create a new method and filter it there or can i use something BEFORE the ForEach Loop?
Pseudo like:
$children = $this->productRepository->findByParent($product->getNumber());
ObjectSortFunction($children, 'getvalidityPeriod');
...and then for each...
Would be awesome if somebody would help me!
Okay after several tries i have a workaround, that can be used as answer, as well ;)
I wrote this method in my repo:
public function findByParentSorted($parentId)
{
$query = $this->createQuery();
$query->matching($query->equals('parent', $parentId));
$query->setOrderings(
[
'validity_period' => \TYPO3\CMS\Extbase\Persistence\QueryInterface::ORDER_ASCENDING
]
);
return $query->execute();
}
I've been working on trying to setup a blog archive for a blog site where the use clicks on a date and the corresponding posts appear. (see image) I understand I need to retrieve all my blog posts and sort by date, but the steps after that are foggy to me. Taking that data then sorting it by month/year and passing it to a template is the part I am having trouble with.
Can someone shed some light on what I am doing wrong or provide a simple working example?
What I have thus far:
public function archiveAction()
{
$em = $this->getDoctrine()->getManager();
// $query = $em->getRepository('AcmeProjectBundle:Blog')
// ->findAll();
$blogs = $em->getRepository('AcmeProjectBundle:Blog')
->getLatestBlogs();
if (!$blogs) {
throw $this->createNotFoundException('Unable to find blog posts');
}
foreach ($blogs as $post) {
$year = $post->getCreated()->format('Y');
$month = $post->getCreated()->format('F');
$blogPosts[$year][$month][] = $post;
}
// exit(\Doctrine\Common\Util\Debug::dump($month));
return $this->render('AcmeProjectBundle:Default:archive.html.twig', array(
'blogPosts' => $blogPosts,
));
}
You want to tell your archiveAction which month was actually clicked, so you need to one or more parameters to it: http://symfony.com/doc/current/book/controller.html#route-parameters-as-controller-arguments (I would do something like /archive/{year}/{month}/ for my parameters, but it's up to you.) Then when someone goes you myblog.com/archive/2014/04, they would see those posts.
Next, you want to show the posts for that month. For this you'll need to use the Doctrine Query builder. Here's one SO answer on it, but you can search around for some more that pertain to querying for dates. Select entries between dates in doctrine 2
I'm using insertRow to populate an empty spreadsheet, it starts off taking about 1 second to insert a row and then slows down to around 5 seconds after 150 rows or so.
Has anyone experienced this kind of behaviour?
There aren't any calculations on the data in the spreadsheet that could be getting longer with more data.
Thanks!
I'll try to be strict.
If you take a look at class "Zend_Gdata_Spreadsheets" you figure that the method insertRow() is written in a very not optimal way. See:
public function insertRow($rowData, $key, $wkshtId = 'default')
{
$newEntry = new Zend_Gdata_Spreadsheets_ListEntry();
$newCustomArr = array();
foreach ($rowData as $k => $v) {
$newCustom = new Zend_Gdata_Spreadsheets_Extension_Custom();
$newCustom->setText($v)->setColumnName($k);
$newEntry->addCustom($newCustom);
}
$query = new Zend_Gdata_Spreadsheets_ListQuery();
$query->setSpreadsheetKey($key);
$query->setWorksheetId($wkshtId);
$feed = $this->getListFeed($query);
$editLink = $feed->getLink('http://schemas.google.com/g/2005#post');
return $this->insertEntry($newEntry->saveXML(), $editLink->href, 'Zend_Gdata_Spreadsheets_ListEntry');
}
In short, it loads your whole spreadsheet just in order to learn this value $editLink->href in order to post new row into your spreadsheet.
The cure is to avoid using this method insertRow.
Instead, get your $editLink->href once in your code and then insert new rows each time by reproducing the rest of behaviour of this method. I.e, in your code instead of $service->insertRow() use following:
//get your $editLink once:
$query = new Zend_Gdata_Spreadsheets_ListQuery();
$query->setSpreadsheetKey($key);
$query->setWorksheetId($wkshtId);
$query->setMaxResults(1);
$feed = $service->getListFeed($query);
$editLink = $feed->getLink('http://schemas.google.com/g/2005#post');
....
//instead of $service->insertRow:
$newEntry = new Zend_Gdata_Spreadsheets_ListEntry();
$newCustomArr = array();
foreach ($rowData as $k => $v) {
$newCustom = new Zend_Gdata_Spreadsheets_Extension_Custom();
$newCustom->setText($v)->setColumnName($k);
$newEntry->addCustom($newCustom);
}
$service->insertEntry($newEntry->saveXML(), $editLink->href, 'Zend_Gdata_Spreadsheets_ListEntry');
Don't forget to encourage this great answer, it costed me few days to figure out. I think ZF is great however sometimes you dont want to rely on their coode too much when it comes to resources optimization.
I want to paginate search results using Zend_Paginator. So I pass my data to a paginator instance:
$paginator = new Zend_Paginator (
new Zend_Paginator_Adapter_DbSelect ( $data )
);
Data is returned this way
public function getData($idArray){
$db = Zend_Db_Table::getDefaultAdapter();
$selectProgramme = new Zend_Db_Select($db);
$selectProgramme->from('programme')
->order('id DESC')
->where('id IN(?)', $idArray);
return $selectProgramme;
}
$idArray is provided by my search implementations. This all works great and I get the correct data and pagination links displayed.
However I can't paginate the result because the pagination links are not valid. So normal pagination would have following link:
mysite.de/home/index/page/1
in search I now have
mysite.de/home/search/page/1
This does not work. Any suggestions how to implement search pagination?
EDIT: I have a HomeController with two actions, index and search action. IndexAction displays all data and I can paginate it.
public function indexAction(){
//...
$paginator = new Zend_Paginator(
new Zend_Paginator_Adapter_DbSelect($data)
);
$paginator->setItemCountPerPage(16)
->setPageRange(20)
->setCurrentPageNumber($this->_getParam('page', 1));
$this->view->data = $paginator;
}
The searchActions handles the search process:
public function searchAction(){
$response = $solr->search($this->getRequest()->getParam('search', null));
//...if items found get the data exactly the same way as in the
// index action, using Zend_Paginator_Adapter_DbSelect
$paginator = new Zend_Paginator(
new Zend_Paginator_Adapter_DbSelect($data)
);
$paginator->setItemCountPerPage(16)
->setPageRange(20)
->setCurrentPageNumber($this->_getParam('page', 1));
$this->view->data = $paginator;
}
So like you see in the search action there is a problem with the search process when I paginate. I need to decide somehow if to search or to paginate. Any suggestions on that?
Since search required the search parameter pagination will fail because when paginating the the search parameter is null.
$sreq = $this->getRequest()->getParam('search', null);
So we need to pass this parameter whenever we paginate our search. I solve this using Zend_Session:
//get search param
$sreq = $this->getRequest()->getParam('search', null);
//store search param in session for pagination
$search = new Zend_Session_Namespace('PSearch');
if($sreq != null){
$search->psearch = $sreq;
}else{
$sreq = $search->psearch;
}
I have this at the top of my searchAction and everything works.
Not sure I understand, but is your problem that the page parameter from the url is not making it's way to the Paginator - e.g. regardless of what page you are on, it is always showing the first 20 results?
If so, have you tried manually setting the page on the paginator:
$page = $this->_getParam('page', 1);
$paginator->setCurrentPageNumber($page);
public function search()
Are you sure that you didn't mistyped here? Should be
public function searchAction()
You put your search data into $response but create paginator instance using $data (which is null)
I want to grab a user's uploads (ie: BBC) and limit the output to 10 per page.
Whilst I can use the following URL:
http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10
The above works okay.
I want to use the query method instead:
The Zend Framework docs:
http://framework.zend.com/manual/en/zend.gdata.youtube.html
State that I can retrieve videos uploaded by a user, but ideally I want to use the query method to limit the results for a pagination.
The query method is on the Zend framework docs (same page as before under the title 'Searching for videos by metadata') and is similar to this:
$yt = new Zend_Gdata_YouTube();
$query = $yt->newVideoQuery();
$query->setTime('today');
$query->setMaxResults(10);
$videoFeed = $yt->getUserUploads( NULL, $query );
print '<ol>';
foreach($videoFeed as $video):
print '<li>' . $video->title . '</li>';
endforeach;
print '</ol>';
The problem is I can't do $query->setUser('bbc').
I tried setAuthor but this returns a totally different result.
Ideally, I want to use the query method to grab the results in a paginated fashion.
How do I use the $query method to set my limits for pagination?
Thanks.
I've decided just to use the user uploads feed as a way of getting pagination to work.
http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10
If there is a way to use the query/search method to do a similar job would be interesting to explore.
I basically solved this in the same way as worchyld with a slight twist:
$username = 'ignite';
$limit = 30; // Youtube will throw an exception if > 50
$offset = 1; // First video is 1 (silly non-programmers!)
$videoFeed = null;
$uploadCount = 0;
try {
$yt = new Zend_Gdata_YouTube();
$yt->setMajorProtocolVersion(2);
$userProfile = $yt->getUserProfile($username);
$uploadCount = $userProfile->getFeedLink('http://gdata.youtube.com/schemas/2007#user.uploads')->countHint;
// The following code is a dirty hack to get pagination with the YouTube API without always starting from the first result
// The following code snippet was copied from Zend_Gdata_YouTube->getUserUploads();
$url = Zend_Gdata_YouTube::USER_URI .'/'. $username .'/'. Zend_Gdata_YouTube::UPLOADS_URI_SUFFIX;
$location = new Zend_Gdata_YouTube_VideoQuery($url);
$location->setStartIndex($offset);
$location->setMaxResults($limit);
$videoFeed = $yt->getVideoFeed($location);
} catch (Exception $e) {
// Exception handling goes here!
return;
}
The Zend YouTube API seems silly as the included getUserUploads method never returns the VideoQuery instance before it actually fetches the feed, and while you can pass a location object as a second parameter, it's an "either-or" situation - it'll only use the username parameter to construct a basic uri or only use the location, where you have to construct the whole thing yourself (as above).
