Populating 'createddate2' field with 'created_date' field.

AbiDhakal

Hello GIS friends,

I have created a field called 'createddate2' and I'm trying to populate that field in Field Maps Designer using the forms option so when people create features using Field Map or web Web Map the 'created_date' value is dynamically added to the new field (createddate2) field.

I have used this '$feature.created_date' expression in the arcade editor form but it does not populate when the feature gets created. It only populates if I go back to the feature to edit and click update.

Your input will be appreciated.

Thank you,
Abi

This is what I'm using:

Hi,

Editor Tracking will systematically track who and when features were last created or edited:

https://doc.arcgis.com/en/arcgis-online/manage-data/manage-editing-hfl.htm#ESRI_SECTION2_60D988F67914496C8D5DC454DF25080D

If you want to manually populate a created date field, you will need to create a field and calculate it using the Form. I'm a bit confused with how many fields you have but to help break down some key concepts:

Calculating $feature.created_date will return the value from the field 'created_date'. I don't believe we have a second field here and there is just some confusion.

As Clay said, using now() or today() would be better to calculate a date. However, if you are editing the feature later on, the created date value will get overwritten by the calculation again.

So you could use the below Arcade expression. It has some additional logic to only calculate when the feature is created (INSERT). It will calculate the date and time if the user uses the form (i.e. in Map Viewer or Field Maps). It won't work if they load in the data some other way, such as ArcGIS Pro, or a map that does not have the form.

// determine our edit mode ("INSERT", "UPDATE", or "DELETE")
var mode = $editcontext.editType

// If mode is insert, return the current time. Can use today() for date only.
if(mode == "INSERT"){
    return now()
}else{
    // return existing value of field we are editing
    return $originalfeature.createddate2
}
