Getting logged in user

[DannyC]

Hi,

How can I get the logged in user?

My scenario...I have a custom field (boolean) in Staff Maintenance which says if a user is allowed to delete sales order lines.

I just need to read the logged-in user custom field and if not allowed to delete sales order lines, stop the deletion. I have got the bit which fires when a line is deleted, now I just need to read the users custom field & back out of the line deletion.
Can you help?

Cheers

Danny

Danny,

Something like this will work (substitute the "AllowSalesOrderLineDelete" with the name of your own custom field) :

Code: Select all

Dim hasPermission As Boolean
For Each customFieldValue As JiwaApplication.CustomFields.CustomFieldValue In JiwaApplication.Manager.Instance.Staff.CustomFieldValues
    If customFieldValue.CustomField.PluginCustomField.Name = "AllowSalesOrderLineDelete" Then
        hasPermission = CBool(customFieldValue.Contents)
        Exit For
    End If
Next

EDIT: I should explain that JiwaApplication.Manager.Instance.Staff is the staff business logic for the currently logged in user - it's a shared (static) property and will always be the staff maintenance business logic associated with the current user - so all fields you see on the staff maintenance form are accessible via that.

I also suspect you may be approaching this wrong. I believe it would be better to add your own abstract permission "AllowSalesOrderLineDelete" and then you can set that permission against user groups and maintain that in the normal permission maintenance built into Jiwa. Let me know if that's something you want to explore and I can provide an example.

Mike,
Yes, I'd like to know about adding our own abstract permission "AllowSalesOrderLineDelete". I think that could be a more elegant solution but I am not sure my client would be setting up different User Groups though, so I am basically replicating in Jiwa 7 what is already in place in 6.5.13 (customised).

I found that I was getting an error on the line
hasPermission = CBool(customFieldValue.Contents)
so I made it a string variable and all OK now.

I am using the following line to fire a Private Sub
AddHandler salesOrderForm.SalesOrder.SalesOrderLineRemoving, AddressOf DeleteLine

but the line
Private Sub DeleteLine(sender As Object, e As System.EventArgs )

is giving a compile error
Method 'Private Sub DeleteLine(sender As Object, e As System.EventArgs )' does not have a signature compatible with delegate 'Delegate Sub SalesOrderLineRemoving...

I basically need a way to back out of the line delete, a bit like the old RtnCancel. I've seen a previous suggestion elsewhere just to do another Read request, but I don't want to read the Sales Order again, I just want to get back to the line state before the delete event.

That event signature looks like this:

Code: Select all

Public Event SalesOrderLineRemoving(sender As Object, e As System.EventArgs, ByVal item As SalesOrderLine)

So just add the last parameter and you should be working. We left that event there simply as a compatibility bridge from V6 script - you can also use the salesOrderForm.SalesOrder.SalesOrderLines.Removing event - which is much the same, but is consistent with our standard design pattern.

Throw a JiwaApplication.Exceptions.ClientCancelled exception to behave like the old rtnCancel of V6.

As for the permissions:

1. Insert an abstract permission into the table:

Code: Select all

INSERT INTO SY_FormsAbstractPermissions(RecID, SY_Forms_ClassName, Name, Description, ItemNo)
SELECT NewID(), 'JiwaFinancials.Jiwa.JiwaSalesUI.SalesOrder.SalesOrderEntryForm', 'Remove Sales Order Line', 'Allow removal of sales order lines',
(SELECT MAX(ItemNo) + 1 FROM SY_FormsAbstractPermissions WHERE SY_Forms_ClassName = 'JiwaFinancials.Jiwa.JiwaSalesUI.SalesOrder.SalesOrderEntryForm')

2. Add the plugin code to examine the permission when a delete of a line is starting and throw a clientcancelled if no permission

Code: Select all

     Public Sub Setup(ByVal JiwaForm As JiwaApplication.IJiwaForm, ByVal Plugin As JiwaApplication.Plugin.Plugin) Implements JiwaApplication.IJiwaFormPlugin.Setup
      Dim salesOrderForm As JiwaSalesUI.SalesOrder.BaseSalesOrderEntryForm = DirectCast(JiwaForm, JiwaSalesUI.SalesOrder.BaseSalesOrderEntryForm)            
      AddHandler salesOrderForm.SalesOrder.SalesOrderLines.Removing, AddressOf SalesOrderLines_Removing
    End Sub
   
   Public Sub SalesOrderLines_Removing(SalesOrderLine As JiwaSales.SalesOrder.SalesOrderLine)
      Dim permission As JiwaApplication.Security.UserGroup.AccessLevels = JiwaApplication.Manager.Instance.Staff.GetAbstractPermission("JiwaFinancials.Jiwa.JiwaSalesUI.SalesOrder.SalesOrderEntryForm", "Remove Sales Order Line")
      
      If permission <> JiwaApplication.Security.UserGroup.AccessLevels.Allow Then
         Throw New JiwaApplication.Exceptions.ClientCancelledException
      End If
   End Sub

3. Set the permissions - on the sales order entry form, utilities ribbon tab - choose Set Permissions then select the Abstract Permissions tab and locate the new permission "Remove Sales Order Line" - set the permission and save. Remember permissions are masked together for all groups the staff member belongs to, as well as the Default Abstract permission.

For completeness a plugin is attached demonstrating this.
