Is is possible to pass to database the following sql query using tableGateway, if so, how would such a command look like ?
UPDATE table_data SET active = not active where table_data.id = 12;
You need to use a Zend\Db\Sql\Expression, this class tells Zend\Db that you know what you're doing and that the content of the string passed to this class shouldn't be transformed, but rather used as is.
// build the table gateway object
$adapter = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');
$tableIdentifier = new TableIdentifier('table_data', 'public');
$tableGateway = new TableGateway($tableIdentifier, $adapter);
// create the filter
$where = new \Zend\Db\Sql\Where();
$where->equalTo('id', '12');
// update table
$tableGateway->update(
['active' => new \Zend\Db\Sql\Expression('not active')],
$where
);

I have an object with several really large string properties. In addition, it has a simple timestamp property.
What I trying to achieve is to update only timestamp property without getting the whole huge object to the server.
Eventually, I would like to use EF and to do in the most performant way something equivalent to this:
update [...]
set [...] = [...]
where [...]
Using the following, you can update a single column:
var yourEntity = new YourEntity() { Id = id, DateProp = dateTime };
using (var db = new MyEfContextName())
{
db.YourEntities.Attach(yourEntity);
db.Entry(yourEntity).Property(x => x.DateProp).IsModified = true;
db.SaveChanges();
}
OK, I managed to handle this. The solution is the same as proposed by Seany84, with the only addition of disabling validation, in order to overcome issue with required fields. Basically, I had to add the following line just before 'SaveChanges():
db.Configuration.ValidateOnSaveEnabled = false;
So, the complete solution is:
var yourEntity = new YourEntity() { Id = id, DateProp = dateTime };
using (var db = new MyEfContextName())
{
db.YourEntities.Attach(yourEntity);
db.Entry(yourEntity).Property(x => x.DateProp).IsModified = true;
db.Configuration.ValidateOnSaveEnabled = false;
db.SaveChanges();
}
A newbie question. I am using EntityFramework 4.0. The backend database has a function that will return a subset of records based on time.
Example of working code is:
var query = from rx in context.GetRxByDate(tencounter,groupid)
select rx;
var result = context.CreateDetachedCopy(query.ToList());
return result;
I need to verify that a record does not exist in the database before inserting a new record. Before performing the "Any" filter, I would like to populate the context.Rxes with a subset of the larger backend database using the above "GetRxByDate()" function.
I do not know how to populate "Rxes" before performing any further filtering since Rxes is defined as
IQueryable<Rx> Rxes
and does not allow "Rxes =.. ". Here is what I have so far:
using (var context = new EnityFramework())
{
if (!context.Rxes.Any(c => c.Cform == rx.Cform ))
{
// Insert new record
Rx r = new Rx();
r.Trx = realtime;
context.Add(r);
context.SaveChanges();
}
}
I am fully prepared to kick myself since I am sure the answer is simple.
All help is appreciated. Thanks.
Edit:
If I do it this way, "Any" seems to return the opposite results of what is expected:
var g = context.GetRxByDate(tencounter, groupid).ToList();
if( g.Any(c => c.Cform == rx.Cform ) {....}
I hope I'm asking this question in an understandable way. I've been working on an app that has been dealing with 1 table ( jobschedule ). So, I have models/Jobschedule.php, models/JobscheduleMapper.php, controllers/JobscheduleController.php, view/scripts/jobschedule/*.phtml files
So in my controller I'll do something like this:
$jobnumber = $jobschedule->getJobnum();
$jobtype = $jobschedule->getJobtype();
$table = $this->getDbTable();
public function listAction()
{
$this->_helper->layout->disableLayout();
$this->view->jobnum = $this->getRequest()->getParam( 'jobnum', false );
$this->view->items = array();
$jobschedule = new Application_Model_Jobschedule();
$jobschedule->setJobnum( $this->view->jobnum );
$mapper = new Application_Model_JobscheduleMapper();
$this->view->entries = $mapper->fetchAll ( $jobschedule );
}
and then in my mapper I I do something like:
$resultSet = $table->fetchAll($table->select()->where('jobnum = ?', $jobnumber)->where('jobtype = ?', $jobtype) );
$entries = array();
foreach ($resultSet as $row) {
$entry = new Application_Model_Jobschedule();
$entry->setJobnum($row->jobnum)
->setJobtype($row->jobtype)
->setJobdesc($row->jobdesc)
->setJobstart($row->jobstart)
->setJobend($row->jobend)
->setJobfinished($row->jobfinished)
->setJobnotes($row->jobnotes)
->setJobid($row->jobid);
$entries[] = $entry;
}
return $entries;
}
Then in my view I can manipulate $entries. Well, the problem I'm coming across now is that there is also another table called 'jobindex' that has a column in it called 'jobno'. That 'jobno' column holds the same record as the 'jobnum' column in the 'jobschedule' table. I need to find the value of the 'store_type' column in the 'jobindex' table where jobindex.jobno = joschedule.jobnum ( where 1234 is the jobno/jobnum for example ). Can someone please help me here? Do I need to create a jobindex mapper and controller? If so, that's done ... I just don't know how to manipulate both tables at once and get the record I need. And where to put that code...in my controller?
If I understand you correctly this is the SQL query you need to extract the data from database:
SELECT `jobschedule`.* FROM `jobschedule` INNER JOIN `jobindex` ON jobindex.jobno = jobschedule.jobnum WHERE (jobindex.jobtype = 'WM')
Assembling this SQL query in Zend would look something like this:
$select->from('jobschedule', array('*'))
->joinInner(
'jobindex',
'jobindex.jobno = jobschedule.jobnum',
array())
->where('jobindex.jobtype = ?', $jobtype);
Let us know if that's what you are looking for.
If I'm understanding you correctly, you'll want to join the 'jobindex' table to the 'jobschedule' table.
...
$resultSet = $table->fetchAll(
$table->select()->setIntegrityCheck(false)
->from($table, array('*'))
->joinLeft(
'jobindex',
'jobindex.jobno = jobschedule.jobnumber',
array('store_type'))
->where('jobnum = ?', $jobnumber)
->where('jobtype = ?', $jobtype)
->where('jobindex.store_type = ?', $_POST['store_num'])
);
....
Depending on how 'jobschedule' is related to 'jobindex', you may want an inner join (joinInner()) instead.
The setIntegrityCheck(false) disables referential integrity between the tables, which is only important if you are writing to them. For queries like this one, you can just disable it and move on (else it will throw an exception).
I am using NestedSet behavior with doctrine 1.2.4 with Zend framework
but i am having some difficulty when inserting a child node of already saved root node
the Doctrine documentation showed the case of creating both root + child elements on the same page
while in my case , the root is already created and saved and i need to insert a child of it
here is an example
//// reading old order info
$order = new Order();
$orderInfo = $order->read($order_id);
$oldOrder = $orderInfo->toArray();
$oldOrder = $oldOrder[0];
//// building the new order information
$renew = new Orders();
$renew->domain_id = (int) $oldOrder["domain_id"];
$renew->auth_id = (int) $oldOrder["auth_id"];
$renew->price = $oldOrder["price"];
$renew->type = (string) $oldOrder["type"];
$renew->timestamp = $oldOrder["timestamp"];
$renew->save();
//// doctrine throwing an error here complaining the $orderInfo should be an instance of Doctrine_Record while its now an instance of Doctrine_Collection
$aa = $renew->getNode()->insertAsLastChildOf($orderInfo);
i don't really know how to retrieve the order from the db and how to convert it to doctrine_record or there is other ways to manipulate this nestedset
any suggestion would be appreciated
Try this:
// This will retrieve the 'parent' record
$orderInfo = Doctrine_Core::getTable('Order')->find($order_id);
// building the new order information
$renew = new Orders();
$renew->domain_id = (int) $oldOrder["domain_id"];
$renew->auth_id = (int) $oldOrder["auth_id"];
$renew->price = $oldOrder["price"];
$renew->type = (string) $oldOrder["type"];
$renew->timestamp = $oldOrder["timestamp"];
$renew->save();
$renew->getNode()->insertAsLastChildOf($orderInfo);
That should get a Doctrine Record of the parent node and you can use that to insert the child as the last child of.
I have a number of FilteringSelect elements within my Zend Framework application that are working fine but they are based on simple queries.
I now need to create a FilteringSelect that will allow me to select the id of one table while displaying the text of field in a related table, i.e. I have two tables groomservices and groomprocedures which are related (i.e. groomprocedures.groomProceduresID has many groomservices.procedure).
The form I'm trying to create is for an appointments table which has many groomservices.groomServicesID values. I want the user to be able to see the name of the procedure while saving the value of the groomservices.groomServicesID using the FilteringSelect.
So far I've not been able to do this in that my FilteringSelect displays nothing, I'm sure this can be done just that the fault is with my inexperience with Zend,Doctrine and Dojo
I'm not sure if my problem is with my autocomplete action(including the query) or with the FilteringSelect element.
Can anyone spot where I've gone wrong in the code sections below, I need to get this working.
My autocomplete action within my controller
public function gserviceAction()
{
// disable layout and view rendering
$this->_helper->layout->disableLayout();
$this->getHelper('viewRenderer')->setNoRender(true);
// get a list of all grooming services IDs and related procedures
$qry= Doctrine_Query::create()
->select('g.groomServicesID,p.groomProcedure')
->from('PetManager_Model_Groomservices g')
->leftJoin('g.PetManager_Model_Groomprocedures p');
$result=$qry->fetchArray();
//generate and return JSON string
$data = new Zend_Dojo_Data('g.groomServicesID',$result);
echo $data->toJson();
}
My FilteringSelect element code
// Create a autocomplete select input for the service
$gservice = new Zend_Dojo_Form_Element_FilteringSelect('gapmtService');
$gservice->setLabel('Proceedure');
$gservice->setOptions(array(
'autocomplete' => true,
'storeID' => 'gserviceStore',
'storeType' => 'dojo.data.ItemFileReadStore',
'storeParams' => array('url' => "/groomappointments/appointment/gservice"),
'dijitParams' => array('searchAttr' => 'groomProcedure')))
->setRequired(true)
->addValidator('NotEmpty', true)
->addFilter('HTMLEntities')
->addFilter('StringToLower')
->addFilter('StringTrim');
Many thanks in advance,
Graham
P.S. orgot to mention I tried the following query in mysql and I gave me what I'm looking for I believe the Doctine query evaluates to the same.
select groomservices.groomservicesID,groomprocedures.groomprocedure from groomprocedures left join groomservices on groomprocedures.groomproceduresID =groomservices.groomProcedure
But I'm not sure if I formatted the query correctly in Doctrine.
EDIT in relation to the flammon's comments
Ok I've set the code to the following but I'm still not getting anything to display.
public function gserviceAction()
{
$ajaxContext = $this->_helper->getHelper('AjaxContext');
$ajaxContext->addActionContexts(array(
'gservice' => 'json'
));
// get a list of all grooming services IDs and related procedures
$qry= Doctrine_Query::create()
->select('g.groomServicesID AS id,p.groomprocedure AS name')
->from('PetManager_Model_Groomservices g')
->leftJoin('g.PetManager_Model_Groomprocedures p');
$this->view->model = (object) array();
$this->view->model->identifier = 'id';
$this->view->model->label = 'name';
$this->view->model->items = array();
$tableRows = $this->dbTable->fetchAll($qry);
foreach ($tableRows as $row) {
$this->view->model->items[] = $row->toArray();
}
}
I'm sure the fault lies with me.
It looks like there's a problem with the data that you're putting in the ItemFileReadStore.
Here are a few pointers.
Consider extending Zend_Rest_Controller for your services. It'll be easier to manage your contexts and your views. You'll be able to do something like this:
public function init()
{
$ajaxContext = $this->_helper->getHelper('AjaxContext');
$ajaxContext->addActionContexts(array(
'gservice' => 'json'
));
}
And it will eliminate the need for the following in each of you service actions.
// disable layout and view rendering
$this->_helper->layout->disableLayout();
$this->getHelper('viewRenderer')->setNoRender(true);
You'll need to either pass the format parameter or use the following plugin to help with the context switch. Passing the format parameter is simpler but it pollutes the url with ?format=json. Here's the Zend documentation on AjaxContext.
Here's a plugin that you can use if you don't want to pass the format parameter.
class Application_Plugin_AcceptHandler extends Zend_Controller_Plugin_Abstract
{
public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
if (!$request instanceof Zend_Controller_Request_Http) {
return;
}
$header = $request->getHeader('Accept');
switch (true) {
case (strstr($header, 'application/json')):
Zend_Registry::get('logger')->log('Setting format to json', Zend_Log::INFO);
$request->setParam('format', 'json');
break;
case (strstr($header, 'application/xml')
&& (!strstr($header, 'html'))):
Zend_Registry::get('logger')->log('Setting format to xml', Zend_Log::INFO);
$request->setParam('format', 'xml');
break;
default:
Zend_Registry::get('logger')->log('Setting format to html', Zend_Log::INFO);
break;
}
}
}
In your controller, instead of echoing the data, create view variables that dojo expects. See this document for the format.
$this->view->model = (object) array();
$this->view->model->identifier = 'id';
$this->view->model->label = 'name';
$this->view->model->items = array();
In your controller, fetch your table rows:
$tableRows = $this->dbTable->fetchAll($select);
or, if you've put model code in a function, it might look more like:
$tableRows = $this->dbTable->fetchGroomProcedures();
Put your row data in the model->items[] array:
foreach ($tableRows as $row) {
$this->view->model->items[] = $row->toArray();
}
Create a view, view/scripts/appointment/gservice.json.phtml and in it put
Zend_Json::encode($this->model)
Use Firebug to see what is returned from your service.
