Web AppBuilder attributes

Question

Hello everyone,

This question is about how to add logic in ArcGIS Online to fields that are populated by application, not by data entry.

I was able to create in ArcGIS Online a Web Mapping Application that has only one layer. The layer is a feature service pointing to SDE in a versioned environment.  The layer is a polygon.

The ArcGIS Online web mapping application works fine. It  allows to digitize a new feature polygon and populate its attributes.

My question is about how pre-populate some  attributes with default values such as:

* Date Created, Date when record was created
* CreatedBy, Editors User ID 
* DateModified, Date when record was modified for the last time
* ModifiedBy, Editors User ID
* PrimaryKeyID, populated with a sequential number, obtained from a sequencer in Oracle
* Other fields  like municipality or commission district that are populated with the value of the Municipality or Commission district where this polygon intersects

For desktop applications I solved this issue creating an ArcMap Add-In.

In the old Web ADF I solved this issue using the event:

* Protected Sub EditorTask1_PostToolExecute(ByVal sender As Object, ByVal editorToolEventArgs As EditorToolEventArgs)  Handles EditorTask1.PostToolExecute

I would like to know how to do that with Web AppBuilder

I know this post has been here a while, but I am going to try the smart editor widget.

Jose,

Your add-in code has little bearing in WAB. The thread I pointed you to allows for autopopulating a field with data before the feature is created on the server. The event that is used is the features before-apply-edits

I took a look to this link. I do not see any event that will trigger when the editor creates or modifies a new feature. This is what I would like to implement that works already in an Add-In: 'Invoked when a feature is created or modified Private Sub Events_OnCreateFeature(ByVal obj As ESRI.ArcGIS.Geodatabase.IObject) Dim inFeature As IFeature = CType(obj, IFeature) Dim featureClass As IFeatureClass Dim intNextMyEditableLayerId As Integer featureClass = CType(obj.Class, IFeatureClass) DisplayFieldNamesAndAliasNames(featureClass) ' MsgBox(featureClass.AliasName) If featureClass.AliasName <> "MyEditableLayer" And featureClass.AliasName <> "APP.MyEditableLayer" Then Exit Sub End If ' GetConnectionStrings() intNextMyEditableLayerId = NextMyEditableLayerNumber() ' Populate the next MyEditableLayerID available ' Dim fieldIndex As Integer = featureClass.FindField("MyEditableLayerID") If fieldIndex = -1 Then Exit Sub End If inFeature.Value(fieldIndex) = intNextMyEditableLayerId
