EF Core - Select on Include and ThenInclude - vb.net

I'm using EF Core 2.1 and i have a Model SettingInformation. The SettingInformation has a Property Setting As ICollection(Of Setting).
The Setting Property has several Properties like Client As Client, User as User and also Workspace As Workspace. It's a bit complicated. Please see the Attached Diagram-Image.
Model-Diagram(Part of it)
Now i have the problem, that i'd like to get the complete Information of a Settinginformation.
The following code i have to get all Informations of a SettingInformation
Public Async Function GetCompleteSettingInformations(settingInfoId As Integer) As Task(Of SettingInformation)
Dim q As IQueryable(Of SettingInformation) = GetSettingInfoDefaultQuery()
q = q.Where(Function(s) s.SettingInformationId = settingInfoId)
q = q.Include(Function(i) i.Settings).ThenInclude(Function(i) i.User) _
.Include(Function(i) i.Settings).ThenInclude(Function(i) i.Workspace) _
.Include(Function(i) i.Settings).ThenInclude(Function(i) i.Client) _
.Include(Function(i) i.Protocol)
Dim ret = Await q.SingleOrDefaultAsync
Return ret
End Function
OK, this code works, but now i'd like to refactor this, because for example, I do not need the UserImage or the 'FailedLogins' of User when the 'LinkedToUser' Property of 'Protocol' is not nothing.
What i needed:
The complete 'SettingInformation' - OK easy
The 'Settings' From 'SettingInformation' (ICollection) - OK i can get this with the Include but in 'Settings':
only the 'UserName', 'FirstName' and 'LastName' from 'User' if 'User' is not Nothing
only the 'ClientShortName' and 'ClientLongName' of 'LinkedToClient' if 'Client is not Nothing
only the 'WorkspaceName' and 'WorkspaceLocation' of 'Workspace' id the 'Workspace' is not Nothing.
I hope so here is anybody who can help me to optimize this Query because now i also cat for example the UserImage for each Setting and this results in a long loadingtime.
EDIT:
OK, now i have tried to do that with EagerLoading. But the Select is ignored. But why? the following code:
'Alle WorkspaceIDs ermitteln für welche es Settingmodifikationen gibt
Dim wsIds As List(Of Integer) = ret.Settings.Where(Function(u) u.WorkspaceId.HasValue).Select(Function(u) u.WorkspaceId.Value).ToList
Await ContextInternal.Workspaces.Where(Function(u) wsIds.Contains(u.WorkspaceId)) _
.Select(Function(su) New Workspace() With {.WorkspaceName = su.WorkspaceName, .WorkspaceLocation = su.WorkspaceLocation, .WorkspaceDesciption = su.WorkspaceDesciption, .WorkspaceId = su.WorkspaceId, .Settings = su.Settings}).AsTracking.LoadAsync
Loads all workspaces that are related in Protocols. I will only get the columns ID, Description, Location and Name. But i get ALL Columns?
The following SQL is generated:
SELECT [u].[WorkspaceId],
[u].[CreatedBy],
[u].[CreatedOn],
[u].[CreationTimestamp],
[u].[DeletedFlag],
[u].[DeletedTimestamp],
[u].[LastUpdateBy],
[u].[LastUpdateOn],
[u].[LastUpdateTimestamp],
[u].[WorkspaceDesciption],
[u].[WorkspaceLastOnline],
[u].[WorkspaceLocation],
[u].[WorkspaceLocked],
[u].[WorkspaceName]
FROM [Workspaces] AS [u]
WHERE [u].[WorkspaceId] IN (1)
ORDER BY [u].[WorkspaceId]

Why is a DOORS Module sometimes null when trying to edit the Module via DXL?

I'm new to DXL programming language in IBM DOORS. However, I think I have managed to do many interesting things: create Modules, create Objects, create Links, delete Objects etc.
However, I have a very specific problem regarding "null" Modules. I've just written null between "" because the modules exist and they are referenced with a correct name.
When doing this:
Module m1 = edit("1. MY_MODULE", false)
save(m1)
close(m1)
An error like this appears:
enter image description here
You could not understand what does that mean as it is spanish. Basically states this: "Module null parameter in the first position of the argument." That means that the "m1" is null, as the parameter for save() method is null.
The point is that it is an error which appears only sometimes. It seems that the Module is null as it has been previously opened and DOORS does not close properly.
Is there any way, any method...whatever to avoid this error?
I assume that the script cannot find the module when another folder is active.
Try
Module m1 = edit ("/myproject/myfolder/mysubfolder/1. MY_MODULE", false)
There might be many reasons that the module can't be opened in edit mode. For example: User do not have write access OR Module is being used by other user, etc.
However, you can get around the error with the below code snippet:
Module m = edit('My_module', false)
if(!null m) {
//execute program
...
}
else {
//do something
}
I hope this helps.
How does your script work? do you open the same module again and again and sometimes get the error or do you open lots of modules and for some of them it works and for others it doesn't? In the latter case, perhaps you misspelled the path. You could add some sanity checks like
string fullPathToMod = "/myproject/myfolder.."
Item i = item fullPathToMod;
if null i then error "there is no item called " fullPathToMod
if "Module" != type i then error "there is an item, but it's not a module, it's a " type i
This is how the Code is structured:
void checkModule(string folderPath, string mName, Skip list, int listSize, int listLastIndex, string headers[], string heading[], string headerKey, bool uniqueKey, string combinedKey[]){
if (module mName){
Folder f = folder(folderPath)
current = f
Module m = edit(folderPath""mName, false)
current = m
Object o = first(m) // error sometimes: Se ha pasado un parametro Module null en una posición de argumento 1
if (o == null){
loadModule(m, list, listSize, listLastIndex, headers, heading)
} else {
updateModule(m, mName, list, listSize, listLastIndex, heading, headerKey, headers, uniqueKey, combinedKey)
save(m)
close(m)
}
if (lastError() != ""){
print "Error: " lastError() "\n"
}
} else {
print "No module " mName ".\n"
}
}
Exactly it breaks in line:
current = m
But as said, only sometimes, not always.
BTW, I'm executing this script via Batch, via Java code. One curious thing is that if I close DOORS, and execute the script it does execute correctly. It is as if it needs to be closed in order to edit modules correctly.
I pressume current can be used more than once with different types of Items. I guess it should not be wrong, but it breaks saying (more or less):
Null value passed to DXL commmand (current Module).
Obviously, it means that m is null, but I cannot see any reason for that.

Using TFS API to rollback a changeset

I am trying to use the TFS API to rollback a changeset.
I tried using all Workspace.Rollback methods but the action does nothing (The GetStatus returned says NoActionNeeded:true).
Has anyone managed to get this to work and can send a working code sample?
From the documentation of the method:
public GetStatus Rollback(
string[] paths,
RecursionType recursion,
VersionSpec itemSpecVersion,
VersionSpec versionFrom,
VersionSpec versionTo,
LockLevel lockLevel,
RollbackOptions options,
string[] itemAttributeFilters
)
I do not understand what the parameter VersionSpec itemSpecVersion means.
It says 'The version spec that identifies the item to which the user is referring.' but then how does it differ from the parameter versionFrom?
What should I pass as the itemAttributeFilters (the last paramter)?
You can rollback changeset programmatically with the following code:
TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("tfsCollectionURL"));
VersionControlServer vcs = (VersionControlServer)tpc.GetService(typeof(VersionControlServer));
string workingDirectory = #"localPath";
string[] workigDnirectoryArr = new string[] { workingDirectory };
Workspace ws = vcs.GetWorkspace("$/serverPath");
int fromCS = 456; //changesetid
int toCS = 495; //changesetid
VersionSpec versionSpecFrom = new ChangesetVersionSpec(fromCS);
VersionSpec versionSpecTo = new ChangesetVersionSpec(toCS);
var status = ws.Rollback(workigDnirectoryArr, RecursionType.None,null, versionSpecFrom, versionSpecTo,LockLevel.None,RollbackOptions.None,null);

dnn 7+ search is not indexing custom module items

I have a dnn 7.2.2 development site running under dnndev.me on my local machine. I have created a simple product catalogue module and am trying to integrate the new search for dnn 7.
Here is the implementation of ModuleSearchBase in my feature/business controller
Imports DotNetNuke.Entities.Modules
Imports DotNetNuke.Services.Exceptions
Imports DotNetNuke.Services.Search
Imports DotNetNuke.Common.Globals
Namespace Components
Public Class FeatureController
Inherits ModuleSearchBase
Implements IUpgradeable
Public Overrides Function GetModifiedSearchDocuments(moduleInfo As ModuleInfo, beginDate As Date) As IList(Of Entities.SearchDocument)
Try
Dim SearchDocuments As New List(Of Entities.SearchDocument)
'get list of changed products
Dim vc As New ViewsController
Dim pList As List(Of vw_ProductList_Short_Active) = vc.GetProduct_Short_Active(moduleInfo.PortalID)
If pList IsNot Nothing Then
''for each product, create a searchdocument
For Each p As vw_ProductList_Short_Active In pList
Dim SearchDoc As New Entities.SearchDocument
Dim ModID As Integer = 0
If p.ModuleId Is Nothing OrElse p.ModuleId = 0 Then
ModID = moduleInfo.ModuleID
Else
ModID = p.ModuleId
End If
Dim array() As String = {"mid=" + ModID.ToString, "id=" + p.ProductId.ToString, "item=" + Replace(p.Name, " ", "-")}
Dim DetailUrl = NavigateURL(moduleInfo.TabID, GetPortalSettings(), "Detail", array)
With SearchDoc
.AuthorUserId = p.CreatedByUserId
.Body = p.ShortInfo
.Description = p.LongInfo
.IsActive = True
.PortalId = moduleInfo.PortalID
.ModifiedTimeUtc = p.LastUpdatedDate
.Title = p.Name + " - " + p.ProductNumber
.UniqueKey = Guid.NewGuid().ToString()
.Url = DetailUrl
.SearchTypeId = 2
.ModuleId = p.ModuleId

SearchDocuments.Add(SearchDoc)
Next
Return SearchDocuments
Else
Return Nothing
End If
Catch ex As Exception

Return Nothing
End Try
End Function
End Class
End Namespace
I cleared the site cache and then I manually started a search re-index. I can see from the host schedule history that the re-index is run and completes.
PROBLEM
None of the items in the above code are added to the index. I even used the Luke Inspector to look into the lucene index and that confirms that these items are not added.
QUESTION
I need help figuring out why these items are not getting added or I need help on how to debug the indexing to see if anything is going run during that process.
Thanks in Advance
JK
EDIT #1
I ran the following procedure in Sql Server to see if the module is even listed in the search modules:
exec GetSearchModules[PortalId]
The module in question does appear in this list. The indexing is called for the featureController, but the results are not added to the lucene index. Still need help.
EDIT #2
So I upgraded to 7.3.1 in the hopes that something during the installation would fix this issue. But it did not. The search documents are still getting created/ returned by the GetModifiedSearchDocuments function but the documents are not being added to the Lucene index and therefore do not appear in the search results.
EDIT #3
The break point is not getting hit like i thought after the upgrade, but I added a try catch to log exceptions and the following error log is getting created when I try to manually re-index (cleaned up to keep it short)
AssemblyVersion:7.3.1
PortalID:-1
PortalName:

ExceptionGUID:d0a443da-3d68-4b82-afb3-8c9183cf8424

Server Name: KING-PC
EDIT #4
Okay, I fixed the problem in edit three following This Disucssion on the DNN issue tracker, but still no items being added to the lucene index.
The breakpoint is hit, and once i leave the debugger running for a while i get the following error:
{"Exception of type 'Lucene.Net.Index.MergePolicy+MergeException' was
thrown."} {"Cannot overwrite:
C:\websites\dnndev.me\App_Data\Search\_1f0.fdt"}
Looks like a permission error. I'll see what I can work out
J King,
I just finished a series on DNNHero.com on Implementing Search in your Module. Parts 3 and 4 are implementing and debugging your ModuleSearchBase implementation.
EDIT: Remove your assignment to the SearchTypeId in your implementation
Also, here is a sample snippet to see how i am setting the attributes of the SearchDocument. Again, watch my video for a whole bunch of other potential pitfalls in the Search implementation.
SearchDocument doc = new SearchDocument
{
UniqueKey = String.Format("{0}_{1}_{2}",
moduleInfo.ModuleDefinition.DefinitionName, moduleInfo.PortalID, item.ItemId),
AuthorUserId = item.AssignedUserId,
ModifiedTimeUtc = item.LastModifiedOnDate.ToUniversalTime(),
Title = item.ItemName,
Body = item.ItemDescription,
Url = "",
CultureCode = "en-US",
Description = "DotNetNuclear Search Content Item",
IsActive = true,
ModuleDefId = moduleInfo.ModuleDefID,
ModuleId = item.ModuleId,
PortalId = moduleInfo.PortalID,
TabId = tab
};

query ebay odata with linq

I am pulling information from eBay using their odata feed. I am trying to use linq to pull the specific information we are after. Using linq I can get down to the specific element holding the information we want. What I can't do is figure out how to query the element data to get the specific child elements I want. I could just parse it but really want to learn linq. I am using vb.net as the language. To get the element I am after I use the following:
Sub Main
dim ns = "http://ebayodata.cloudapp.net/"
dim url as string = "http://ebayodata.cloudapp.net/Items?search=1756-L65"
Using reader As XmlReader = XmlReader.Create(url)
While reader.Read()
If reader.NodeType = XmlNodeType.Element AndAlso reader.Name = "entry" Then
GetChildContentElements(reader)
End If
End While
End Using
End Sub
Private Sub GetChildContentElements(reader As XmlReader)
' move to first child
While reader.Read()
If reader.NodeType = XmlNodeType.Element AndAlso reader.Name = "m:properties" Then
Exit While
End If
End While
Dim bookXml As XElement = DirectCast(XNode.ReadFrom(reader), XElement)
Console.WriteLine(bookXml)
End Sub
One of the elements this returns looks like:

I am struggling with querying the above to get the specific child elements we need to work with. The ":" in the tags seems to be confusing using namespaces. What I would like to do is to be able to query the element to get values for d:Id, d:UserId, d:Currentprice, etc. Any suggestions would be welcomed.
Try using WCF data services client. It can generate proxy classes for you that would simplify things. Refer to the documentation here.
Sample code for doing custom url's with generated WCF DS client,
const string baseAddress = "http://ebayodata.cloudapp.net/";
EBayData ebay = new EBayData(new Uri(baseAddress));
var items = ebay.Execute<Item>(new Uri(baseAddress + "Items?search=1756-L65"));
foreach (var item in items)
{
Console.WriteLine(item.Title);
}

How to add extra data to a member in MDS?

I'm running MDS on a virtual machine and trying to access the service from my host OS.
I've been able to add something to the database but my data is all over the place and in the Master Data Manager (website) I don't see the new member.
I suppose I shouldn't be using Attributes but something else but what and how? Are there tutorials because I can't find any ...?
Here's the code I'm using:
International international = new International();
EntityMembers entityMembers = new EntityMembers();
// Set the modelId, versionId, and entityId.
entityMembers.ModelId = new Identifier { Name = modelName };
entityMembers.VersionId = new Identifier { Name = versionName };
entityMembers.EntityId = new Identifier { Name = entityName };
entityMembers.MemberType = memberType;
Collection<Member> members = new Collection<Member>();
Member aNewMember = new Member();
aNewMember.MemberId = new MemberIdentifier() { Name = employee.FullName, Code = aNewCode, MemberType = memberType };
Collection<MDS.Attribute> attributes = new Collection<MDS.Attribute>();
MDS.Attribute attrOrgUnit = new MDS.Attribute();
attrOrgUnit.Identifier = new Identifier() { Name = "OrganizationalUnit" };
attrOrgUnit.Value = employee.OrganizationalUnit;
attrOrgUnit.Type = AttributeValueType.String;
attributes.Add(attrOrgUnit);
aNewMember.Attributes = attributes.ToArray();
members.Add(aNewMember);
entityMembers.Members = members.ToArray();
// Create a new entity member
OperationResult operationResult = new OperationResult();
clientProxy.EntityMembersCreate(international, entityMembers, false, out operationResult);
HandleOperationErrors(operationResult);
I have been able to fix my own problem.
First of all: creating separate variables with collections and converting them to arrays afterwards is not necessary. The code from the tutorials works but fails to mention that, when adding the service reference, you have to configure it (right-click on the service reference -> configure) to use Collections as "Collection type" instead of arrays and to generate message contracts.
Second, the code above with the attributes is correct and works perfectly. The problem I had which failed to add messages with attributes was unrelated. It was a connection/authentication problem between my Host OS and Guest OS.
Hope this helps someone.
