Everytime i add new item to database using Livedata, it is retriving all data from database. But i want only the latest updated item to display on the screen when i click save button
Here is the Code
MAIN ACTIVITY
viewModel.retrieveItem(idd).observe(this , Observer{
selectedItem = it
if(selectedItem != null){
entry = selectedItem as Entry
bind(entry)
}else{
blank()
}
private fun bind(entry: Entry){
editText.setText(entry.diaryEntry,TextView.BufferType.SPANNABLE)
}
VIEW MODEL
fun retrieveItem(id: Int): LiveData<Entry> {
return diaryDao.getItem(id)
}
DAO
#Query("SELECT * from diary WHERE id = :id")
fun getItem(id: Int): LiveData<Entry>
Any help would be Appreciated

I have problems with my dialog field. I have button that opens dialog tab with field. It was supposed to show on that field lookup exact records(i guess i need select there by one field value). Right now i have this code:
DialogField Journal = dialog.addField(extendedTypeStr(JournalId));
This dialog line adds a field with all values on that EDT. I have 3 journal types - NEW, UPDATE, DELETE. Right now on that field lookup it shows me all 3 journal types. I want to make custom lookup that shows exact type , example - if i click that button on journal that has type "NEW", then it should show only "NEW" type of journal types on lookup. I heard there is something like dialog.addLookup or something. Can someone help me?
You already added your dialog field (in the dialog() method). Now add the dialogRunPost() method that is executed after the form GUI is initialized. At that point you can fetch the underlying FormStringControl behind the dialog field. Subscribing to the FormStringControl.OnLookup event allows you to override the lookup.
I did not have some journal data available, so I created a similar example with customers. My example dialog (MyDialog) takes a source customer (customerCaller) and shows a dialog with a custom lookup that only shows customers with the same customer group.
My example is also a standalone, runnable class and is not called from a form. Comments have been added to indicate where this affects the code.
Full example
public class MyDialog extends Runbase
{
// fields
protected Args args;
protected CustTable customerCaller;
protected DialogField dfCustomerId;
// construct
public static MyDialog newArgs(Args _args)
{
MyDialog ret = new MyDialog();
ret.args = _args;
return ret;
}
// initialize
public boolean init()
{
boolean ret = super();
// validate and fetch caller
if (args.record() && args.record().TableId == tableNum(CustTable))
//if (args.caller() && args.caller().dataset() == tableNum(CustTable)) --> when called from form
{
customerCaller = args.record();
//customerCaller = args.caller().record();
}
else
{
throw error(Error::missingRecord('My Dialog'));
}
return ret;
}
// build dialog
public Object dialog()
{
Dialog ret = super();
// optional reference to visualize the input
ret.addText('Caller customer group = ' + customerCaller.CustGroup);
// add field
dfCustomerId = ret.addField(extendedTypeStr(CustAccount)); // default lookup = all CustTable.AccountNum values
return ret;
}
public void dialogPostRun(DialogRunbase dialog)
{
super(dialog);
// subscribe to lookup event
FormStringControl fscCustomerId = dfCustomerId.control();
fscCustomerId .OnLookup += eventhandler(this.customerId_OnLookup);
}
// custom lookup for customer id
protected void customerId_OnLookup(FormControl _sender, FormControlEventArgs _e)
{
// cancel default
FormControlCancelableSuperEventArgs eventArgs = _e;
eventArgs.CancelSuperCall();
// define lookup query (list all customers with same customer group as input customer)
Query query = new Query();
QueryBuildDataSource qbds = SysQuery::findOrCreateDataSource(query, tableNum(CustTable));
SysQuery::findOrCreateRange(qbds, fieldNum(CustTable, CustGroup)).value(SysQuery::value(customerCaller.CustGroup));
// do lookup
SysTableLookup lookup = SysTableLookup::newParameters(tableNum(CustTable), _sender);
lookup.parmQuery(query);
lookup.addLookupfield(fieldNum(CustTable, AccountNum), true);
lookup.addLookupfield(fieldNum(CustTable, CustGroup));
lookup.performFormLookup();
}
// run dialog
public static void main(Args _args)
{
// I am running this dialog directly (not from a form), generating some random input
CustTable customer;
select firstonly customer where customer.CustGroup != '';
_args.record(customer);
// end of random input
MyDialog md = MyDialog::newArgs(_args);
md.init();
if (md.prompt())
{
md.run();
}
}

I have a custom action on screen CR304000 - OpportunityMaint in the Quotes tab of the grid view that marks a field called IsPrimary in the CRQuote DAC as true for the current record in the Quotes view. These project Quotes are associated with the current opportunity as well as with a related PMQoute in the PMQuoteMaint BLC. The PMQuoteMaint BLC has a view called Activties that has all the CRActivities associated with the PMQuote. I created a custom field in the CRActivity called IsPrimary and added it to the Activities view in the PMQuoteMaint BLC grid.
My goal was to override the Action in the OpportunityMaint to update the IsPrimary field in CRActivity to true or false depending on what the Action in OpportunityMaint is toggling. However, my IsPrimary field in PMQuoteMaint is not toggling. My code attempts to get Current Quote OpportunityMain and then create a PMQuoteMaint graph and set the Current record. Then iterate though Activies view and set the IsPrimary field accordingly. Like I said, not having success because I'm not sure that my code is successfully retrieving the correct Activities.
There might be a better way to access CRActivity associated with a PMQuote, but I'm not sure. Any help would be appreciated. Here is code:
public virtual IEnumerable PrimaryQuote(PXAdapter adapter)
{
foreach (CROpportunity opp in adapter.Get())
{
if (Quotes.Current?.IsPrimary != true)
{
var selectExistingPrimary = new PXSelect<CRQuote, Where<CRQuote.quoteID,
Equal<Required<CRQuote.quoteID>>>>(this);
CRQuote primary = selectExistingPrimary.Select(opp.DefQuoteID);
if (primary != null && primary.QuoteID != Quotes.Current.QuoteID && primary.Status ==
PM.PMQuoteStatusAttribute.Closed)
{
throw new PXException(PM.Messages.QuoteIsClosed, opp.OpportunityID,
primary.QuoteNbr);
}
var quoteID = Quotes.Current.QuoteID;
var opportunityID = this.Opportunity.Current.OpportunityID;
this.Persist();
PXDatabase.Update<Standalone.CROpportunity>(
new PXDataFieldAssign<Standalone.CROpportunity.defQuoteID>(quoteID),
new PXDataFieldRestrict<Standalone.CROpportunity.opportunityID>(PXDbType.VarChar,
255, opportunityID, PXComp.EQ)
);
this.Cancel.Press();
CROpportunity rec = this.Opportunity.Search<CROpportunity.opportunityID>
(opportunityID);
yield return rec;
}
yield return opp;
}
``` My OverRide
public PXAction<CROpportunity> primaryQuote;
[PXUIField(DisplayName = Messages.MarkAsPrimary)]
[PXButton]
public virtual IEnumerable PrimaryQuote(PXAdapter adapter)
{
// this is currently selected record in quotes grid
var currQuoteNbr = Base.Quotes.Current.QuoteNbr;
bool isPrimary2;
foreach (CRQuote quote in Base.Quotes.Select())
{
var quoteNbr = quote.QuoteNbr;
if(quoteNbr.Trim() == currQuoteNbr.Trim())
{
isPrimary2 = true;
}
else
{
isPrimary2 = false;
}
PXTrace.WriteInformation(string.Format("Quote: {0} Value:
{1}",quoteNbr.ToString(),isPrimary2.ToString()));
var PMQuoteMaintGraph = PXGraph.CreateInstance<PMQuoteMaint>();
PMQuoteMaintGraph.Quote.Current = PMQuoteMaintGraph.Quote.Search<PMQuote.quoteNbr>
(quoteNbr.Trim()); // this is the current quote
foreach (CRActivity activity in PMQuoteMaintGraph.Activities.Select())
{
CRActivityExt itemExt = PXCache<CRActivity>.GetExtension<CRActivityExt>(activity);
itemExt.UsrPrimary = isPrimary2;
PMQuoteMaintGraph.Activities.Cache.Persist(PXDBOperation.Update);
PXDatabase.Update<CRActivity>(new PXDataFieldAssign<CRActivityExt.usrPrimary>
(isPrimary2));
}
}
return Base.primaryQuote.Press(adapter);

This is my Controllers Edit Method in Httpost
[HttpPost]
public ActionResult Edit(Employee employee)
{
if (!ModelState.IsValid)
{
var department = db.Departments.ToList();
var viewModel = new EmployeeViewModel
{
Departments = department,
Employees = db.Employees.ToList()
};
return View("Index", viewModel);
}
db.Entry(employee).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
this method creates new data instead of updating data.
The problem is you're trying to update Employee instance directly based from action parameter without seeking any matching record first, hence EF "unaware" if the entity should be modified and treat its state as EntityState.Added in this line:
db.Entry(employee).State = EntityState.Modified;
What you should do is using SingleOrDefault() or FirstOrDefault() to fetch matching record based from Id property, update all required properties then attach Employee instance into Employees entity and set its state as EntityState.Modified:
[HttpPost]
public ActionResult Edit(Employee employee)
{
if (!ModelState.IsValid)
{
var department = db.Departments.ToList();
var viewModel = new EmployeeViewModel
{
Departments = department,
Employees = db.Employees.ToList()
};
return View("Index", viewModel);
}
// find employee with matching ID first
var selectedEmployee = db.Employees.SingleOrDefault(x => x.Id == employee.Id);
// update all properties
selectedEmployee.Name = employee.Name;
// other properties here
// attach the context
db.Employees.Attach(selectedEmployee);
// set modified state and save all changes
db.Entry(selectedEmployee).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}

with code from Load value from popup to InventoryID field question am able to set the InventoyID from popup to the InventoryID field but the default behavior of Acumatica is missing, like after InventoryID is set from poup, am selecting Item Class then a pop up is firing and asking for confirmation, generally this happen only when we update Item Class for already created Item.

You can try to skip the message window by overriding the Field Verifying on the stock item page for InventoryItem.ItemClassID. You should use some condition to indicate you are running your customer process so the standard message will appear for normal use on the stock items page.
public virtual void InventoryItem_ItemClassID_FieldVerifying(PXCache cache, PXFieldVerifyingEventArgs e, PXFieldVerifying del)
{
try
{
del?.Invoke(cache, e);
}
catch (PXDialogRequiredException)
{
var someSkipMessageWindowCondition = true;
if (someSkipMessageWindowCondition)
{
return;
}
throw;
}
}
Because of the use of the private property doResetDefaultsOnItemClassChange in the Base graph, the process will function as if the message box was answered YES to default the field values from the new item class. If you do not want the values to change using the new class you will need to cancel the field defaultings for the fields found in InventoryItem_ItemClassID_FieldUpdated in the Base graph. This will point out which fields are being updated when doResetDefaultsOnItemClassChange == true.
A better answer to your question would be automatically answering NO which I am unsure how to do. Would be nice to know how do perform that function if someone else knows how to make that call.
am generating a pop on one new button click in stock Items screen, inside popup have two buttons, user select some data from fields in the popup and then click on ok, then inventoryId should be formed with some special characters and then it should display in InventoryID field. I can form the InventoryID but unable to display it in InventoryID field.
[PXButton]
[PXUIField(DisplayName = "Generate")]
public virtual void GenerateInv()
{
InventoryItemExt ext = Base.Item.Cache.GetExtension<InventoryItemExt>(Base.Item.Current);
Base.Item.Current.InventoryCD = ext.UsrInvId;
Base.Item.Cache.Insert(Base.Item.Current);
}
I had this issue before,
and the following code was provided by acumatica. you may try the same.
here in the below code, inventoryCD contains the value, i wanted to set.
InventoryItem item = PXCache<InventoryItem>.CreateCopy(Base.Item.Current);
OrderedDictionary keys = new OrderedDictionary(StringComparer.OrdinalIgnoreCase)
{
{
typeof(InventoryItem.inventoryCD).Name,
adapter.View.Cache.GetValue(adapter.View.Cache.Current,
typeof(InventoryItem.inventoryCD).Name)
}
};
OrderedDictionary vals = new OrderedDictionary(StringComparer.OrdinalIgnoreCase)
{
{
typeof(InventoryItem.inventoryCD).Name, inventoryCD
}
};
adapter.View.Cache.Update(keys, vals);
if (adapter.Searches != null && adapter.Searches.Length > 0)
{
adapter.Searches[0] = inventoryCD;
}
return adapter.Get();
Also make sure your function have the correct input and the return type
IEnumerable GenerateInv(PXAdapter adapter)
