How do I change the default value for a table field (has a domain) in an existing Hosted Feature Service? AGOL's Data>>Fields>>Details interface allows me to edit domain entries (very nice) but I can't change the Default Value. ArcPro's "Assign Default To Field tool" gives me a "000664: Invalid input: This type of dataset is not supported" error.  The lookup table is in a Many-to-1 relationship with a point layer in the same Hosted Feature Service. Thank you for your time!   ... View more

Allow for easy switching between multiple ArcGIS Online organization accounts in Field Maps with and without internet access.  Pain points: Switching accounts during field work is impossible without internet access.  Depending on the mobile device setup, many are required to type in passwords every time. Currently, we have to log out and in again every time we switch between our Department's and a National AGOL organization (NIFC). We have users with 3 or more orgs too that are used in the field (i.e. federal, state, local, and agency orgs). ... View more

Data Expressions for Dashboard's List widget is a joy! The following code works well but only returns Domain Codes. Can DomainName($feature, 'Trap_Region') somehow be used to get Domain Names? var portal = Portal('https://www.arcgis.com/'); var fs = FeatureSetByPortalItem( portal, 'XXXXXXXXXXXXXXXXXXXXXXX', 1, ['Trap_ID','Trap_Region'], false ); // Trap count grouped by trap region var fs_gp = GroupBy(fs, ['Trap_Region'], [{name: 'Total_Traps', expression: 'Trap_ID', statistic: 'COUNT' }]); return fs_gp   ...

I'm trying to bulk calculate acres for polygons in a hosted feature service using ArcGIS Online Notebook Standard (no ArcPy) Is there a bug in the ArcGIS Online Notebook (API v1.8.4 at posting time) implementation of the arcgis.geometry.areas_and_lengths() function or is the API description missing vital information? Through a lot of trial and error I figured out a set of parameters that ArcGIS Online Notebook would accept For length_unit it will only accept an ID number - e.g. 9002 - not esriSRUnit_Foot For area_unit it will only accept  a dictionary  - e.g. {"areaUnit" : "esriAcres"} - not an ID number or esriAcres I could only get it to work with parameters formatted the following way:   from arcgis.geometry import lengths, areas_and_lengths, project from arcgis.geometry import Point, Polyline, Polygon, Geometry # create a JSON polygon geometry geom_json = {"rings" : [[[0, 0], [0, 10], [10, 10],[10, 0],[0, 0]]], "spatialReference" : {"wkid" : 4326}} # create Geometry object test_geom = Geometry(geom_json) # calculate areas_and_lengths areas_and_lengths(test_geom, 9035, {"areaUnit" : "esriAcres"}, "geodesic", 4326, None, False)     I welcome any suggestions on a more efficient way to calculate acres than one by one converting a Feature into a Geometry to then run areas_and_lengths(). Without using ArcPy though  🙂 edit: fixed typos ... View more

Currently AGOL's Hosted Feature Service (and Hosted View FS) Overview pages list all related layers and tables but do not show that there are DB relationships. To my limited knowledge, you either have to know they are there or discover them through Attribute Expression widgets (popup - editors), ArcGIS REST Administrator Directory (JSON in "Update Definition"), etc.  It would be very helpful if the Overview page would: Display which layer/table is related to which in perhaps a tree structure (great for nested relationships). Show Relationship Class attributes such as: Cardinality (1:1, 1:M, etc.) - a must Primary and Foreign Keys for each relationship - a must Relationship Class name Forward Path label Backward Path label etc. ...
