I am a newbie in nativescript. Currently I am creating app with 2 properties in my customer-view-model.js as shown below, and it's running well.
function Customer( nama ) {
this.nama = nama;
this.complete = false;
}
module.exports = Customer;
When I am add more properties like code below then my app thrown an error with message ReferenceError: telpon is not defined
function Customer( nama ) {
this.nama = nama;
this.telpon = telpon;
this.complete = false;
}
module.exports = Customer;
I have no idea what i'm missing. Please help :)
You got "nama" from parameter at first line, that's why first was good but not telpon, so if its input parameter you need to add it first line (as definition) or use something from 3 lines inside function to set variable to some default value
this.something are properties of model,
this.telpon was done okey but you were assigning variable to property which was undefined
function Customer( nama,telpon ) {
this.nama = nama;
this.telpon = telpon;
//this.telpon = 1;
//this.telpon = "string";
//this.telpon = false/true;
this.complete = false;
}
module.exports = Customer;

I'm working with Lumen framework v5.8 (it's the same as Laravel)
I have a command for read a big XML (400Mo) and update datas in database from datas in this file, this is my code :
public function handle()
{
$reader = new XMLReader();
$reader->open(storage_path('app/mesh2019.xml'));
while ($reader->read()) {
switch ($reader->nodeType) {
case (XMLREADER::ELEMENT):
if ($reader->localName === 'DescriptorRecord') {
$node = new SimpleXMLElement($reader->readOuterXML());
$meshId = $node->DescriptorUI;
$name = (string) $node->DescriptorName->String;
$conditionId = Condition::where('mesh_id', $meshId)->first();
if ($conditionId) {
ConditionTranslation::where(['condition_id' => $conditionId->id, 'locale' => 'fr'])->update(['name' => $name]);
$this->info(memory_get_usage());
}
}
}
}
}
So, I have to find in the XML each DescriptorUI element, the value corresponds to the mesh_id attribute of my class Condition.
So, with $conditionId = Condition::where('mesh_id', $meshId)->first(); I get the Condition object.
After that, I need to update a child of Condition => ConditionTranslation. So I just get the element DescriptorName and update the name field of ConditionTranslation
At the end of the script, you can see $this->info(memory_get_usage());, and when I run the command the value increases each time until the script runs very very slowly...and never ends.
How can I optimize this script ?
Thanks !
Edit : Is there a way with Laravel for preupdate multiple object, and save just one time at the end all objects ? Like the flush() method of Symfony
There is a solution with ON DUPLICATE KEY UPDATE
public function handle()
{
$reader = new XMLReader();
$reader->open(storage_path('app/mesh2019.xml'));
$keyValues = [];
while ($reader->read()) {
switch ($reader->nodeType) {
case (XMLREADER::ELEMENT):
if ($reader->localName === 'DescriptorRecord') {
$node = new SimpleXMLElement($reader->readOuterXML());
$meshId = $node->DescriptorUI;
$name = (string) $node->DescriptorName->String;
$conditionId = Condition::where('mesh_id', $meshId)->value('id');
if ($conditionId) {
$keyValues[] = "($conditionId, '".str_replace("'","\'",$name)."')";
}
}
}
}
if (count($keyValues)) {
\DB::query('INSERT into `conditions` (id, name) VALUES '.implode(', ', $keyValues).' ON DUPLICATE KEY UPDATE name = VALUES(name)');
}
}
so far I was able to avoid hardcoding my LUIS appId and key by doing the following:
var luisService = new LuisService(new LuisModelAttribute(ConfigurationManager.AppSettings["LuisAppId"], ConfigurationManager.AppSettings["LuisAppKey"]));
context.Call(new LuisDialog(luisService), ResumeAfterDialog);
And then having my LUIS dialog declared as:
[Serializable]
public class LuisDialog : LuisDialog<object>
{
public LuisDialog(ILuisService ls) : base(ls)
{
}
....
}
}
But I would also like to be able to set SpellCheck=true, Log, Verbose and other parameters available in the LuisModel attribute programmatically, is there a way of doing that?
Thanks
I figured it out, I just need to set the LuisModelAttribute properties in code before creating the LuisService:
var luisSettings = new LuisModelAttribute(ConfigurationManager.AppSettings["LuisAppId"], ConfigurationManager.AppSettings["LuisAppKey"]);
luisSettings.Log = true;
luisSettings.SpellCheck = true;
luisSettings.Log = true;
var luisService = new LuisService(luisSettings);
context.Call(new LuisDialog(luisService), ResumeAfterDialog);
I am using the following code snippet to retrieve choice items for a specific choice list
Map<Serializable, Serializable> items = new HashMap<Serializable, Serializable>();
Iterator<Choice> choiceIterator = choiceList.get_ChoiceValues().iterator();
while(choiceIterator.hasNext()){
Choice choice = choiceIterator.next();
if(choice.get_ChoiceType() == ChoiceType.INTEGER){
itemKey = choice.get_ChoiceIntegerValue();
}else{
itemKey = choice.get_ChoiceStringValue();
}
items.put(itemKey, ((LocalizedStringImpl)choice.get_DisplayNames().get(0)).get_LocalizedText());
}
but get_LocalizedText() method just get the value with locale en_us. So what if i want to get other locales i.e ar_eg?
Thanks in advance.
You need to call get_LocaleName() method on the LocalizedString object and find out if this is the right locale you are looking for. Here is sample code:
LocalizedStringList lsList = choice.get_DisplayNames();
Iterator<LocalizedString> dit= lsList.iterator();
boolean lnFound = false;
while(dit.hasNext())
{
LocalizedString ls = dit.next();
String ln = ls.get_LocaleName();
String lt = ls.get_LocalizedText();
if(_locale.equalsIgnoreCase(ln))
{
ls.set_LocalizedText(_value);
lnFound = true;
}
}
Say I have a model with following properties:
function ViewModel() {
this.SetupTime = ko.observable();
this.CloseTime = ko.observable();
this.MinHrs = ko.observable();
}
I need to add a validation rule so that MinHrs > (SetupTime + CloseTime). Whenever one of the three fields is changed this validation should fire. I know I have to write a custom validation for this, for example:
ko.validation.rules['ValidWorkRange'] = {
validator: function (val, setuptime, closetime, minhrs) {
return minhrs > (setuptime+closetime);
},
message: '(Shift End - Shift Start) >= Shortest Work Segment'
};
I'm not sure what I have done there is correct, also not sure how to call this validation within the observable.
Can someone please help me out?
Thanks in advance
Yes you are right, you should create a custom validation to achieve your goal. And you have no need to call validation function, it will be automatically called whenever its associated dependency (observables) will change.
Wroking Fiddle
Note : Please apply the other necessary validation like number etc. Because if you enter text in any input field in the fiddle code than result may be an error.
Here is the custom validation code :
var ValidWorkRange = function(val, param)
{
if(val && param){
var minHrs = parseInt(val, 10);
var setupTime = parseInt(param[0](), 10);
var closeTime = parseInt(param[1](), 10);
return minHrs > (setupTime+closeTime);
}
};
And like this you can apply it on your observable :
function ViewModel() {
var self = this;
self.SetupTime = ko.observable();
self.CloseTime = ko.observable();
self.MinHrs = ko.observable().extend
({
validation: {
validator: ValidWorkRange,
message: 'Not valid.',
params: [self.SetupTime, self.CloseTime]
}
});
}
I don't know so much about ko validation but probably it can be usefull for you

Appearently, I got an error if using the following code. It said:
Cannot implicity converrt type System.Linq.IQueryable<AnonymousType> to System.Collection.Generic.IEnumerable.
Please advise how I can fix this?
public IEnumerable<Session> GetAllListDetailConsumer(string refId)
{
ObjectQuery<Session> sessions = db.Sessions;
ObjectQuery<SessionsList> sessionsLists = db.SessionsList;
var query =
from s in sessions
join sList in sessionsLists on s.ReferralListID equals sList.ReferralListID
where s.ReferralListID == new Guid(refId)
select new SessionConsumerList
{
ReferralListID = s.ReferralListID,
SessionServerId = s.SessionServerID,
ApplicationID = s.ApplicationID,
// ...
ConsumerID = sList.ConsumerID,
ConsumerFirstName = sList.ConsumerFirstName,
ConsumerFamilyName = sList.ConsumerFamilyName,
// ...
};
return query.ToList();
}
You are selecting using select new, which would create an anonymous type, you need to project to class Session in your query like.
select new Session
{
....
But remember if your Session class is a representing a table in your database/data context, then you can't project to that class, instead you may have to create a temporary class and project the selection to that class.
EDIT (Since the question now has been edited)
Now you are selecting new SessionConsumerList and you are returning IEnumerable<Session>, you need to modify method signature to return IEnumerable<SessionConsumerList>
Why not separate the creation of the SessionConsumerList in another method? Makes the code a lot cleaner. Like this:
public static SessionConsumerList CreateSessionConsumerList(
Session s,
SessionsList sList)
{
return new SessionConsumerList
{
ReferralListID = s.ReferralListID,
SessionServerId = s.SessionServerID,
ApplicationID = s.ApplicationID,
// ...
ConsumerID = sList.ConsumerID,
ConsumerFirstName = sList.ConsumerFirstName,
ConsumerFamilyName = sList.ConsumerFamilyName,
// ...
};
}
And then:
var query =
from s in sessions
join sList in sessionsLists on s.ReferralListID equals sList.ReferralListID
where s.ReferralListID == new Guid(refId)
select CreateSessionConsumerList(s, sList);
