This seems like a question that should have been answered already, but I haven't been able to find any discussion of this.
I have an array of items, some of which may be selected:
function Item(name) {
this.name = name;
this.selected = ko.observable(false);
}
function ViewModel() {
var self = this;
this.items = ko.observableArray([]);
this.selected = ko.computed(function() {
return ko.utils.arrayFilter(self.items(), function (item) {
return item.selected();
});
}, this);
}
Since viewmodel.selected() depends on viewmodel.items(), whenever I add a new object to items the selected observable also changes, even if the added item is not selected. How do I prevent this.selected() from updating if no new items are actually selected?
I am not sure you can achieve this with a pure ko.computed solution.
Maybe you could subscribe to your "items" changes. When one item is added, you check if it is selected and push it to another observableArray if it is.
See the first answer to this question : Determine which element was added or removed with a Knockoutjs ObservableArray
It would allow you to subscribe to specific changes on your "items" (item added or deleted).

Developer's version of Acumatica 2020R1 is installed locally. Data for sample tenant MyTenant from training for I-300 were loaded, and WSDL connection established.
DefaultSoapClient is created fine.
However, attempts to export any data by using Getlist cause errors:
using (Default.DefaultSoapClient soapClient =
new Default.DefaultSoapClient())
{
//Sign in to Acumatica ERP
soapClient.Login
(
"Admin",
"*",
"MyTenant",
"Yogifon",
null
);
try
{
//Retrieving the list of customers with contacts
//InitialDataRetrieval.RetrieveListOfCustomers(soapClient);
//Retrieving the list of stock items modified within the past day
// RetrievalOfDelta.ExportStockItems(soapClient);
RetrievalOfDelta.ExportItemClass(soapClient);
}
public static void ExportItemClass(DefaultSoapClient soapClient)
{
Console.WriteLine("Retrieving the list of item classes...");
ItemClass ItemClassToBeFound = new ItemClass
{
ReturnBehavior = ReturnBehavior.All,
};
Entity[] ItemClasses = soapClient.GetList(ItemClassToBeFound);
string lcItemType = "", lcValuationMethod = "";
int lnCustomFieldsCount;
using (StreamWriter file = new StreamWriter("ItemClass.csv"))
{
//Write the values for each item
foreach (ItemClass loItemClass in ItemClasses)
{
file.WriteLine(loItemClass.Note);
}
}
The Acumatica instance was modified by adding a custom field to Stock Items using DAC, and by adding several Attributes to Customer and Stock Items.
Interesting enough, this code used to work until something broke it.
What is wrong here?
Thank you.

In the request you have the following line: ReturnBehavior = ReturnBehavior.All
That means that you try to retrieve all linked/detail entities of the object. Unfortunately, some object are not optimized enough to not affect query performance in GetList scenarios.
So, you have to options:
Replace ReturnBehavior=All by explicitly specifying linked/detail entities that you want to retrieve and not include Attributes into the list.
Retrieve StockItem with attributes one by one using Get operation instead of GetList.
P.S. The problem with attributes will most likely be fixed in the next version of API endpoint.
Edit:
Code sample for Get:
public static void ExportItemClass(DefaultSoapClient soapClient)
{
Console.WriteLine("Retrieving the list of item classes...");
ItemClass ItemClassToBeFound = new ItemClass
{
ReturnBehavior = ReturnBehavior.Default //retrieve only default fields (without attributes and other linked/detailed entities)
};
Entity[] ItemClasses = soapClient.GetList(ItemClassToBeFound);
foreach(var entity in ItemClasses)
{
ItemClass itemClass= entity as ItemClass;
ItemClass.ReturnBehavior=ReturnBehavior.All;
// retrieve each ItemClass with all the details/linked entities individually
ItemClass retrievedItemCLass = soapClient.Get(itemClass);
}
I have a custom module that uses Kentico API (DocumentHelper) to update certain fields of my document and then publish but I do not want it to trigger the event handlers that are linked to my document page type. I tried adding comments to .Publish("admin_edit") hoping that I can catch it from the WorkflowEventargs parameter but the VersionComment property always return null. Is there a way to accomplish this in Kentico?
update field:
var document = DocumentHelper.GetDocument(documentID, tree);
var workflowManager = WorkflowManager.GetInstance(tree);
var workflow = workflowManager.GetNodeWorkflow(document);
if (workflow != null)
{
document.CheckOut();
document.SetValue("SomeFIeld", "some value");
document.Update(true);
document.CheckIn();
document.Publish("admin_edit");
}
event handler:
public override void Init()
{
WorkflowEvents.Publish.After += Publish_After;
}
private void Publish_After(object sender, WorkflowEventArgs e)
{
if (!string.IsNullOrEmpty(e.VersionComment) &&
e.VersionComment.Contains("admin_edit"))
return;
}
You always get null for Version information, because that is related to the 'Page versioning' events, specially for 'SaveVersion'. You can find more about that on this link. If you expand 'Properties' you will see which properties are populated for the specific event. In your case, you can try something like this, to add your message for last version and then check for that comment on 'Publish_After' event, see code bellow:
var document = DocumentHelper.GetDocument(documentID, tree);
var workflowManager = WorkflowManager.GetInstance(tree);
var workflow = workflowManager.GetNodeWorkflow(document);
if (workflow != null)
{
document.CheckOut();
document.SetValue("SomeFIeld", "some value");
document.Update(true);
document.CheckIn(versionComment: "admin_edit");
document.Publish();
}
and then, in event handler, take last version and check for comment like this:
if (e.PublishedDocument?.VersionHistory?.Count > 0)
{
var lastVersion = e.PublishedDocument.VersionHistory[0] as VersionHistoryInfo;
if (lastVersion.VersionComment.Equals("admin_edit"))
{
return;
}
}
NOTE: In case that you have a lot of concurrent content editors, there is a chance that your last version is not version from API (someone changed content and saved it right after your API call made change). There is a low chance for that, but still is possible. If this is something that you will use often, you must take it in consideration. This code is tested for Kentico 11.
My module creates a custom content item through the controller:
private ContentItem createContentItem()
{
// Add the field
_contentDefinitionManager.AlterPartDefinition(
"TestType",
cfg => cfg
.WithField(
"NewField",
f => f
.OfType(typeof(BooleanField).Name)
.WithDisplayName("New Field"))
);
// Not sure if this is needed
_contentDefinitionManager.AlterTypeDefinition(
"TestType",
cfg => cfg
.WithPart("TestType")
);
// Create new TestType item
var newItem = _contentManager.New("TestType");
_contentManager.Create(TestItem, VersionOptions.Published);
// Set the added boolean field to true
BooleanField newField = ((dynamic)newItem).TestType.NewField as BooleanField;
newField.Value = true;
// Set title (as date created, for convenience)
var time = DateTime.Now.ToString("MM-dd-yyyy h:mm:ss tt", CultureInfo.InvariantCulture).Replace(':', '.');
newItem.As<TitlePart>().Title = time;
return newItem;
}
The end result of this is a new TestType item with a field that's set to true. Viewing the content item in the dashboard as well as examining ContentItemVersionRecord in the database confirms that the value was set correctly.
However, queries don't seem to work properly on fields that are set in this manner. I found the record IntegerFieldIndexRecord, which is what I assume projections use to fill query result pages. On this, the value of TestField remains at 0 (false), instead of 1 (true).
Going to the content item edit page and simply clicking 'save' updates IntegerFieldIndexRecord correctly, meaning that the value is now picked up by the query. How can the record be updated for field values set programmatically?
Relevant section of migration:
SchemaBuilder.CreateTable(typeof(TestTypePartRecord).Name, table => table
.ContentPartRecord()
);
ContentDefinitionManager.AlterTypeDefinition(
"TestType",
cfg => cfg
.DisplayedAs("Test Type")
.WithPart(typeof(TitlePart).Name)
.WithPart(typeof(ContainablePart).Name)
.WithPart(typeof(CommonPart).Name)
.WithPart(typeof(IdentityPart).Name)
);
Edit: The fix for this is to manually change the projection index record whenever changing a field value, using this call:
_fieldIndexService.Set(testResultItem.As<FieldIndexPart>(),
"TestType", // Resolves as TestTypePart, which holds the field
"newField",
"", // Not sure why value name should be empty, but whatever
true, // The value to be set goes here
typeof(bool));
In some cases a simple contentManager.Publish() won't do.
I've had a similar problem some time ago and actually implemented a simple helper service to tackle this problem; here's an excerpt:
public T GetStringFieldValues<T>(ContentPart contentPart, string fieldName)
{
var fieldIndexPart = contentPart.ContentItem.As<FieldIndexPart>();
var partName = contentPart.PartDefinition.Name;
return this.fieldIndexService.Get<T>(fieldIndexPart, partName, fieldName, string.Empty);
}
private void SetStringFieldValue(ContentPart contentPart, string fieldName, IEnumerable<int> ids)
{
var fieldIndexPart = contentPart.ContentItem.As<FieldIndexPart>();
var partName = contentPart.PartDefinition.Name;
var encodedValues = "{" + string.Join("},{", ids) + "}";
this.fieldIndexService.Set(fieldIndexPart, partName, fieldName, string.Empty, encodedValues, typeof(string));
}
I've actually built this for use with MediaLibrary- and ContentPicker fields (they encode their value as string internally), so it might not be suitable for the boolean field in your example.
But it can't be that hard to implement, just look at the existing drivers and handlers for those fields.
There are 2 ways to fix this:
1) Ensure the newly created item is getting published by calling ContentManager.Publish() as Orchard.Projections.Handlers.FieldIndexPartHandler listens to the publish event to update the FieldIndexPartRecord
2) use IFieldIndexService to update FieldIndexPartRecord manually, see implementation of Orchard.Projections.Handlers.FieldIndexPartHandler to get in idea how to do this
Hope this helps.
:edit
Due to calling Create(...Published) the ContentManager.Published() won't do anything as the item is already considered published.
You can do the following to force the publish logic to run:
bool itemPublished = newItem.VersionRecord.Published;
// unpublish item first when it is already published as ContentManager.Publish() internally first checks for published flag and when set it aborts silently
// -> this behaviour prevents calling publish listeners
if (itemPublished)
_contentManager.Unpublish(newItem);
// the following call will result in calls to IContentHandler.Publishing() / IContentHandler.Published()
_contentManager.Publish(newItem);
or just create the item as a draft and publish it when everything is setup correctly.
I currently have a recalc function that resets the shipping cost field if a line item has changed, but I really only need to do that if the item has a weight. How do I retrieve the weight of the changed line item?
Here's what I currently have:
function recalc(){
nlapiSetFieldValue('shippingcost', '0.00');
}
recalc is fired only when a change to a line item affects the Total of the transaction, and as such, may not be a reliable event for what you want to accomplish.
I would recommend against using validateLine as that event should be used to determine whether the new value for a field is valid.
I would advise you to use fieldChanged for responding to a field value that has changed. Something like:
function fieldChanged(type, name, linenum) {
if (type == 'item') {
if (name == 'item') {
handleItemChange(linenum);
}
}
}
function handleItemChange(linenum) {
var itemWeight = parseFloat(nlapiGetFieldValue('item', 'weight', linenum)) || 0;
if (itemWeight > 0) {
nlapiSetFieldValue('shippingcost', 0);
}
}
You may also want to consider the postSourcing event instead of fieldChanged, depending on which fields should actually trigger this logic.
Small segue, recalc doesn't give you a way to get the current line of the sublist, you'd need to loop through the whole sublist anytime a single line was changed.
Try validateLine, something like:
function validateLine(listType){
//To get the item weight, you could create a
//custom transaction column field that sourced the item weight.
if(nlapiGetCurrentLineItemValue(listType,'custcolitemWeight') > 0){
nlapiSetFieldValue('shippingcost','0.00')
}
//or you could source directly from the item record using nlapiLookupField
// Depending on your use case either could be appropriate
if(nlapiLookupField('item',nlapiGetCurrentLineItemValue(listType,'item'),'weight')){
nlapiSetFieldValue('shippingcost','0.00')
}
//you *need* to return true with the validate* event functions.
return true;
}
This (untested) example only handles line additions. If users are allowed to remove items, you'll need to implement a similar validateDelete that also reverts your changes.
I have a simple IBackgroundTask implementation that performs a query and then either performs an insert or one or more updates depending on whether a specific item exists or not. However, the updates are not persisted, and I don't understand why. New items are created just as expected.
The content item I'm updating has a CommonPart and I've tried authenticating as a valid user. I've also tried flushing the content manager at the end of the Sweep method. What am I missing?
This is my Sweep, slightly edited for brevity:
public void Sweep()
{
// Authenticate as the site's super user
var superUser = _membershipService.GetUser(_orchardServices.WorkContext.CurrentSite.SuperUser);
_authenticationService.SetAuthenticatedUserForRequest(superUser);
// Create a dummy "Person" content item
var item = _contentManager.New("Person");
var person = item.As<PersonPart>();
if (person == null)
{
return;
}
person.ExternalId = Random.Next(1, 10).ToString();
person.FirstName = GenerateFirstName();
person.LastName = GenerateLastName();
// Check if the person already exists
var matchingPersons = _contentManager
.Query<PersonPart, PersonRecord>(VersionOptions.AllVersions)
.Where(record => record.ExternalId == person.ExternalId)
.List().ToArray();
if (!matchingPersons.Any())
{
// Insert new person and quit
_contentManager.Create(item, VersionOptions.Draft);
return;
}
// There are at least one matching person, update it
foreach (var updatedPerson in matchingPersons)
{
updatedPerson.FirstName = person.FirstName;
updatedPerson.LastName = person.LastName;
}
_contentManager.Flush();
}
Try to add _contentManager.Publish(updatedPerson). If you do not want to publish, but just to save, you don't need to do anything more, as changes in Orchard as saved automatically unless the ambient transaction is aborted. The call to Flush is not necessary at all. This is the case both during a regular request and on a background task.
