"Nested" Relationships in AGOL

[LisaHuggins]

I have a feature class, "patchlocation".  This FC is related to table "Rack" 1:M.  The table "Rack" is then related to a table "Patchpanel" 1:M.  In ArcMap, I can identify a "patchlocation" on the map and then look at related racks and from each rack, related patchpanels.  I published map to service but when I identify in AGOL, I only get related racks.  Is this type of "nested" relationship supported in AGOL?

Lisa,

I dealt with this same issue a few years ago because I wanted to create the Macroinvertebrate Water Monitoring Map. My dataset seems similar. I had sites (FC) with multiple visits per site (1:M FC > table) with multiple macros collected at each site visit (1:M table > table).

AGOL only allows you to see one level of relationships. However, you can use the JavaScript API to customize returns of 'deeper' relationships as we did in our map from above. I worked with a developer, as I am still early in my JavaScript programming skills, so I can't offer much more than this!

I have not seen a widget yet to replicate what happens when you use the identify tool in ArcMap where you get to see the whole relationship tree. The ability to add related values to the popup is a good step, but certainly does not meet the complete need in your case.

Thanks for the response!  Always nice to know that someone is listening.  And while Im sorry there is not currently an out of the box solution, it's good to know there is a solution out there we can work towards.  Thanks again.

Hey Lisa,

Nested relationships are planned to be supported in ArcGIS Online later this year.

Cheers

Woohoo! That's nice to hear.  We'll be waiting.  Thanks

Its later in the year.. still no nested relationships Feature >> 1:M >> Table   ----   Table >> 1:M >> Table.

Is there a better timeline as to when this will be released?

We are in 2019, does nested relationships in AGOL webb app is enabled or not?

[RussRoberts]

Yes you could view nested relationships in the Map Viewer. Using the Popup Show Related Records > Using the table view to see the next level of related records. You can also use WAB popup to navigate through nested relationships.

Thank you for your answer.

Is it normal that if I add a MapService hosted on an ArcGIS Server into the AGOL webmap viewer (https://www.arcgis.com/home/webmap/viewer.html) I just see the first level of relationships in the table view? Nested relationships are displayed as empty (0).
