Salesforce Trigger - Prevent Parent Case Closure if Parent Case has open Child Cases - triggers

I have the following Apex trigger which should prevent a Parent Case from closing if the parent case has open child cases. Kindly assist with trouble shooting as the Apex Trigger is not firing.
trigger CaseTriggerCloseChild on Case ( before update ) {
Set < Id > setCaseIds = new Set < Id >();
Map < Id, Integer > mapOpenCaseCount = new Map < Id, Integer >();
for ( Case objCase : trigger.new ) {
if ( objCase.Status == 'Closed' ) {
setCaseIds.add( objCase.Id );
}
}
for ( Case objCase : [ SELECT ParentId FROM Case WHERE ParentId IN: setCaseIds AND IsClosed = false ] ) {
if ( mapOpenCaseCount.containsKey( objCase.ParentId ) ) {
mapOpenCaseCount.put( objCase.ParentId, mapOpenCaseCount.get( objCase.ParentId ) + 1 );
} else {
mapOpenCaseCount.put( objCase.ParentId, 1 );
}
}
for ( Case objCase : trigger.new ) {
if ( objCase.Status == 'Closed' ) {
if ( mapOpenCaseCount.containsKey( objCase.Id ) ) {
objCase.addError( 'You cannot close this Case. It has ' + mapOpenCaseCount.get( objCase.Id ) + ' open Child Cases.' );
}
}
}
}


Looks like your map of open cases is keyed on the parent ID and you are using the current case ID to look for open cases. You'll need to restructure it some.

How to take number from concrete row surrounded by text in TIFF file (if viewed in notepad) and use it in scripting in Digital Micrograph?

Update#2 link to TIFF file (needed row is 135) https://drive.google.com/file/d/1g3e3xenm5b-awQwpvfZyhfXIqSVGGw2t/view
(Updated#1)
Dear stackoverflow users,
first of all I need to mention that I am amateur in programming but I admire coding possibilities and try to exploit them in my work.
In our laboratory we acquire images using Zeiss microscopes, which save images in TIFF format with detailes attached as a text if viewed in notepad. Thus, when you put TIFF image in a Digital Micrograph it is not calibrated and you have to manualy calibrate each image.
On the other hand, in these TIFF files there is a row (its number is fixed but differs from microscope to microscope) with a pixel size looking like these:
"Pixel Size = 0.6 nm"
My thought was, that if I could extract number from this row and put it in script declaring dimensions for every open image - it would save a lot of time.
I made a few steps:
Image img
img.GetFrontImage()
While(img.ImageIsValid())
{Number pixelsize
pixelsize = 0.5
img.imagesetdimensionscale(0,pixelsize)
img.imagesetdimensionscale(1,pixelsize)
img.imagesetdimensionunitstring(0,"nm")
img.imagesetdimensionunitstring(1,"nm")
imagedisplay imgdisp=img.imagegetimagedisplay(0)
imgdisp.applydatabar(2)
img.SetName(img.GetName()+"*")
img := FindNextImage(img)
}
As I understand:
I used a script from "DM script book" for apllying action on all opened images
I create variable number called pixelsize
I set it manually from file
I put it in dimensions scale in x and y
I set dimensions units as "nm"
I also create scalebar.
So Could you tell me please:
Is it possible to set pixelsize equal to a number in a row in a TIFF file?
Sincerely,
Shadowbane

Yes, it is doable but not trivial. I've found an old script of mine in which I was doing that. I'm no longer in the position to test it, so I'm not 100% certain it will work.
Also, it is a bit too long for posting here, so I've also put it under this pastebin link.

check_megaraid_sas nagios plugin explanation

Can anyone explain following piece of code in https://github.com/simondeziel/custom-nagios-plugins/blob/master/plugins/check_megaraid_sas . (line num 220-223)
Why this code is there
} elsif ( $slotnumber != 255 ) {
$pdbad++;
$status = 'CRITICAL';
}

It makes sense to look at the complete section:
PDISKS: while (<PDLIST>) {
if ( m/Slot Number\s*:\s*(\d+)/ ) {
$slotnumber = $1;
$pdcount++;
} elsif ( m/(\w+) Error Count\s*:\s*(\d+)/ ) {
if ( $1 eq 'Media') {
$mediaerrors += $2;
} else {
$othererrors += $2;
}
} elsif ( m/Predictive Failure Count\s*:\s*(\d+)/ ) {
$prederrors += $1;
} elsif ( m/Firmware state\s*:\s*(\w+)/ ) {
$fwstate = $1;
if ( $fwstate eq 'Hotspare' ) {
$hotsparecount++;
} elsif ( $fwstate eq 'Online' ) {
# Do nothing
} elsif ( $fwstate eq 'Unconfigured' ) {
# A drive not in anything, or a non drive device
$pdcount--;
} elsif ( $slotnumber != 255 ) {
$pdbad++;
$status = 'CRITICAL';
}
}
} #PDISKS
That section loops over a list of PDs (Primary Disks?), and I assume that this file / program output contains a human readable status for every attached device. The code looks at every line and performs some actions depending on the content of that line:
$slotnumber is assigned whenever there is Slot Number : ... in the contents of PDLIST. From looking at the logic, if there is a Firmware state line that is not Hotspare, Online or Unconfigured, and the $slotnumber is not 255, then something went horribly wrong and the status is considered CRITICAL. The number of bad PDs ($pdbad) is then increased by one.

Pimcore: Retrieve Single Object List by Multiple Class Types

I currently have a controller that pulls objects from the Pimcore Objects exactly how the sample data demonstrated.
What we need to accomplish with this build, is to allow for a "Featured" category to be assigned to any NewsArticle object or EventsArticle object. We need to pull a combined list from both NewsArticle and EventsArticle objects that also have the Featured category assigned to them. We need to keep track of all the IDs returned in this list, and exclude them from the single track lists so that they aren't displayed twice on the same page.
These are our two single track lists which work as expected, limited by custom properties that live on the document.
Requirements:
Filter by featured category.
Prevent any post from being listed twice.
Able to sort by date asc or desc.
// TODO: List Featured News and Events Objects...
// $this->view->featured = $featuredList->getObjects();
// List News Objects...
$newsList = new Object\NewsArticle\Listing();
$newsList->setOrderKey( "date" );
$newsList->setOrder( "DESC" );
$newsList->setLimit( $this->document->getProperty( 'newsLimit' ) );
// TODO: Exclude any IDs in $this->view->featured
$this->view->news = $newsList->getObjects();
// List Events Objects...
$eventsList = new Object\EventsArticle\Listing();
$eventsList->setOrderKey( "date" );
$eventsList->setOrder( "DESC" );
$eventsList->setLimit( $this->document->getProperty( 'eventsLimit' ) );
// TODO: Exclude any IDs in $this->view->featured
$this->view->events = $eventsList->getObjects();

This approach will give you the featured list:
$featuredListObj = \Pimcore\Model\Object::getByPath("featured-list");
$featuredListObjId = $featuredListObj->getId();
$eventClassId = \Pimcore\Model\Object\ClassDefinition::getByName("news")->getId();
$newsClassId = \Pimcore\Model\Object\ClassDefinition::getByName("event")->getId();
$combinedListing = new Pimcore\Model\Object\Listing();
$combinedListing->setCondition("o_className IN ('event','news') AND o_id IN (
SELECT o_id FROM object_$eventClassId WHERE categories LIKE '%,$featuredListObjId,%'
UNION SELECT o_id FROM object_$newsClassId WHERE categories LIKE '%,$featuredListObjId,%'
)");
foreach ($combinedListing as $item) {
echo get_class($item) . "<br>";
}

After some toil I've figured out a way to do this. It may not be optimal, but it works and gets the job done.
The reason why I've found this way to be most effective is because setCondition will also check non-target classes for columns they might not have, causing the list to fail.
#
# Hybridized Featured Articles List
#
# Get News and Events Objects...
$hybridList = new Object\Listing();
$hybridList->setCondition( "o_className IN ( 'newsArticle', 'eventsArticle' )" );
# Get a list of IDs for News and Events that have the "featured" category...
$featuredList = array();
foreach( $hybridList->getObjects() as $obj ) {
foreach( $obj->categories as $obj_cat ) {
if( $obj_cat->o_key == 'featured' ) {
$key = strtotime( $obj->date->date );
$key .= str_pad( $obj->o_id, 8, "0", STR_PAD_LEFT );
$featuredList[ $key ] = $obj;
break;
}
}
}
# Sort and Slice the list...

How to filter 'p' within an id of multiple id selection?

I'm trying to select multiple ids + an id that would select only paragraphs within that id
$('#big8,#divmenu,#workstext.has('p')').each(function(i) {
$(this).delay((i + 1) * 250).fadeIn(2000);
});
The error i get is: "Uncaught SyntaxError: missing ) after argument list"

Your problem is your code, the . in the $('') part means a class with the name that follows, also, you use ' in this too, escape it or use double quotes, namely: $("''"); or $('\'').
Your code should be more like this:
$('#big8, #divmenu, #workstext').has('p').each(function(i) {
$(this).delay((i + 1) * 250).fadeIn(2000);
});
OR
$("#big8, #divmenu, #workstext").has("p").each(function(i) {
$(this).delay((i + 1) * 250).fadeIn(2000);
});
EDIT
Try this:
$( "#big8, #divmenu" ).each( function ( i )
{
$( this ).delay(( i + 1 ) * 250 ).fadeIn( 2000 );
} );
$( "#workstext" ).has( "p" ).each( function ( i )
{
$( this ).delay(( i + 1 ) * 250 ).fadeIn( 2000 );
} );

How to use Create Command in yii2?

i want to create a new table and then insert value into it using create command. This is the code which i tried
if ( $model->save() )
{
$first_val = $model->num_start - 1;
$connection = \Yii::$app()->db;
$transaction = $connection->beginTransaction();
try
{
$q = "CREATE TABLE range_{$model->id}( id INT(11) NOT NULL AUTO_INCREMENT,PRIMARY KEY (id) ); " ;
$connection->createCommand($q)->execute(); // new table created
$transaction->commit();
if ( $model->num_start > 1 )
{
$r = "INSERT INTO range_{$model->id}( id ) VALUES ({$first_val});" ;
$connection->createCommand($r)->execute(); // new value inserted
$transaction->commit();
}
}
catch (Exception $e)
{
// react on exception
$transaction->rollback();
}
return $this->redirect( [ 'index' ] );
}
when i try to run this code i get an error Call to undefined method Yii::app() How can i use the create command in Yii2?

You have mixed both yii and yii2:
Use:
\Yii::$app->db;
Instead of
\Yii::$app()->db;
