Just wondering what I am doing wrong here, I am trying to give a GUID a null value using expression. tried everything but can't seem to get the syntax working!
((ISNULL(IN_EntityId )? (DT_GUID) "00000000-0000-0000-0000-000000000000" : IN_EntityId )!= (ISNULL( EntityId) ? (DT_GUID)"00000000-0000-0000-0000-000000000000" : EntityId))

I am trying to dynamically render class based off actionTypeCreate. This is a method that simply returns a boolean value based off the prop actionType that is passed. I am triggering this method on the mounted hook and confirmed it is returning properly.
Now I am trying to return the class value of 'col-md-4' if actionTypeCreate. If not actionTypeCreate I want to return the class 'col-md-6'.
This is what I have but it is not working:
:class="{toggleActionType : 'col-md-4' ? 'col-md-6'}"
I tried to reference this existing question, but I did not get it.
You can do it as follows:
:class="{'col-md-4' : toggleActionType , 'col-md-6' : !toggleActionType }"
According to the Vue documentation itself you can do it in two ways. First, you can use Array Syntax and this is broadly used to apply a list of classes.
Array Syntax
:class="[toggleActionType ? 'col-md-4' : 'col-md-6']"
Or you can do it as normal by Object Syntax but it does not accept ternary operations, so you have to do it this way:
Object Syntax
:class="{'col-md-4' : toggleActionType , 'col-md-6' : !toggleActionType}"
Try this:
:class="[toggleActionType : 'col-md-4' ? 'col-md-6']"
I want use the 'in' keyword in 'eval' function in which I am getting error that 'in' is not recognized by drools. So I have multiple values which I want check against a particular fact's attribute
when
$person : Person(PIN in ("123","456","789"))
then
//do something
end
//Like this I want use it in eval
when
$person : Person()
eval($person.PIN in ("123","456","789"))
then
//do something
end
But it is showing compile time error.
is there any other way to do it.
Edited
So I have some conditions in Decision Table where I want to use eval because other ways are not helpful in my scenario, below snapshot will Explain
SnapShot 1: Decision Table without eval()
SnapShot 2: Decision Table with eval()
Issue in first snapshot:
When compiling the spreadsheet the condition goes to the second lines object like below code : this is how it gets interpreted
when
personMap : PersonMap ()
basicEligiblePerson : Person( personalAddress.PIN in ($param) ) from
personMap.AddressesList
addresses : Address() from basicEligiblePerson.AddressesList
personalAddress : PersonalAddress() from addresses.PersonalAddress
then
basicEligiblePerson.setEligibility(true);
end
Issue in second snapshot :
When compiling this spreadsheet the condition goes to eval() function but 'in' keyword does not work in eval().
when
personMap : PersonMap ()
basicEligiblePerson : Person( personalAddress.PIN in ($param) ) from
personMap.AddressesList
addresses : Address() from basicEligiblePerson.AddressesList
personalAddress : PersonalAddress() from addresses.PersonalAddress
eval( personalAddress.PIN in ($param) )
then
basicEligiblePerson.setEligibility(true);
end
what should I do?
First sample given in your question is sufficient for the validation. You don't need to use eval.
when
$person : Person(PIN in ("123","456","789"))
then
//do something
end
If your requirement is to set eligibility to true for a given set of PINs, then you don't really need a decision table. I don't completely understand your POJO structure, so if Person class has a member variable addressList and AddressList class has a member personalAddress which has the member variable pin, you can achieve the results using the following rule. Please note that the nested fields are referred using the member variable names, not the class names. Also when you access the nested elements, if any of the elements can be null, please add the null check as well to avoid null pointer exceptions.
when
$basicEligiblePerson : Person( addressesList.personalAddress.pin in ("1234", "4567") )
then
$basicEligiblePerson.setEligibility(true);
end
I want to sum two BigDecimal, but before to do that I need to know that this values are not null (I could made this check Java side, but I want to try Jasper side).
So, I do this check:
($F{a} != null ? $F{a} : new BigDecimal(0))
($F{b} != null ? $F{b} : new BigDecimal(0))
Now, I have to sum a and b, but if I do:
($F{a} != null ? $F{a} : new BigDecimal(0)).add($F{b} != null ? $F{b} : new BigDecimal(0))
I get:
The current expression is not valid. Please verify it!
How can I solve?
Assuming that your fields are both of class java.math.BigDecimal and that you are using language="java" or language="groovy"
There is nothing wrong with your expression!
Don't worry about the Expression Editor it simple can not understand that ($F{a} != null ? $F{a} : new BigDecimal(0)) is a java.math.BigDecimal, that is why it states "The current expression is not valid. Please verify it!" and show's a red dot at .add.
Just press "OK" and enjoy your result!
If you like to simplify your expression's or just remove the error in the expression editor, you can use variables.
I had the same problem. Explicitly casting a new BigDecimal eliminates the exception. Use
new Bigdecimal($F{a} != null ? $F{a} : new BigDecimal(0))
and there should be no problem.
I was wrong. The cast eliminated Jaspers' compile time exception but in runtime it threw 'The constructor BigDecimal(NumberComparable) is undefined.' Note the compile time exception is bad since their approach is to check each keystroke and throw up a warning as you type. In order to complete typing the conditional, it takes double the effort in warnings closing. Now I need my code to work without the cast and I'm about to try
($F{denominator} == 0 ? 0 : $F{numerator} / $F{denominator})
I am using Ichikawa CakePHP MongoDB plugin. I have a problem in using unset in it. I have tried the command in shell:
db.patents.update({}, {$unset : {"lv.2" : 1 }},{'multi':true})
db.patents.update({},{$pull:{pid:"2"}},{'multi':true})
These are working fine.
But when I am converting them to CakePHP command as follows:
$this->Detail->updateAll(array('$unset'=>array('lv.2'=>1,array('multi'=>true))));
Then it doesn't work and gives error:
MongoCollection::update(): expects parameter 1 to be an array or object, boolean given
Can anyone help me to figure out the problem.
Thanks.
There are no conditions
The error message means that the query being generated is the equivalent of:
db.details.update(true
This can be confirmed by checking the query log (easy if you're using debug kit).
How is that happening
The second parameter for model updateAll is missing, which means it will have the default:
public function updateAll($fields, $conditions = true) {
^
return $this->getDataSource()->update($this, $fields, null, $conditions);
}
Therefore in the mongodb datasource class - the conditions passed are true:
public function updateAll(&$Model, $fields = null, $conditions = null) {
^
As a consequence, the resultant update statement has true as the first parameter, not an array.
Correct syntax
The correct syntax for such a query is:
$this->Detail->updateAll(
array('$unset'=>array('lv.2'=>1))
array() # <- do not omit this
);
Note that it's not necessary to specify 'multi'=>true as the datasource does that for you, especially not in the fields argument.
Before anything I am aware of the multiple questions asked concerning this exception. I have looked through them but have not found an answer for my particular problem. Most of the questions use the Zend_Db_Table::getDefaultAdapter(); , and I am not using that. Instead I am using an Application_Model_DbTable_Name and am left wondering if it´s possible to do so.
Also, I do have access since that´s the first thing I checked when I saw the error. The database is local and I access it with the same user/password through MySqlWorkBench.
My goal is to delete a row when two columns meet the criteria set in the controller action, like so:
public function deleteAction(){
$request = $this->getRequest();
$this->_validateDigit($request->getParam('id'));
// _validateDigit(..) checks that the variable is numeric and if it´s not it redirects to
// an error page
$db = new Application_Model_DbTable_BecasPerfiles();
$select = $db->select();
$select->where('unidad=?', $this->_getUnit())
->where('id=?', (int) $request->getParam('id'));
$db->delete($select->getPart(Zend_Db_Select::WHERE));
$this->_redirect('/profile/view-profiles/unit/'.$this->_getUnit());
}
private function _getUnit()
{
return Zend_Registry::getInstance()['session']->unit;
//unit is nothing but a string
}
Here is my DbTable class (real simple):
class Application_Model_DbTable_BecasPerfiles extends Zend_Db_Table_Abstract
{
protected $_name = 'becas_perfiles';
}
Here is the error that spits out:
Message: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in
your SQL syntax; check the manual that corresponds to your MySQL server version for
the right syntax to use near 'AND (id=7))' at line 1
Here is what calls my attention AND (id=7)), see the extra parenthesis? where is that coming from?
Here is the result of var_dump($select->getPart(Zend_Db_Select::WHERE));
array(2) { [0]=> string(33) "(unidad='Galería de Arte ULPGC')" [1]=> string(10) "AND (id=7)" }
Just for the fun of it, I tried switching the order of the where clause:
$select->where('id=?', (int) $request->getParam('id'))
->where('unidad=?', $this->_getUnit());
Here is the output:
Message: SQLSTATE[42000]: ...
syntax to use near 'AND (unidad='Galería de Arte ULPGC'))' at line 1
There it is again, AND (unidad='Galería de Arte ULPGC')) that second parenthesis. I don´t really know if that´s the problem (but I figure it is because otherwise I don´t know what could posssibly be wrong).
I tried just using one where condition (like id), and it deleted just fine. I´d really appreciate your help, thank you!
The problem here is that there is a mismatch between what getPart() returns and what delete() expects.
As you already pointed out, var_dump($select->getPart(Zend_Db_Select::WHERE)); also returns the logical operators in the where statement, but the delete() operator either expects an array in the form "field => value" or a string containing the full where clause.
So the simplest (untested) approach to fix your problem would be to pass $db->delete(implode(' ', $select->getPart(Zend_Db_Select::WHERE))); so that delete() receives a fully qualified where clause as string instead of an array it cannot handle.
