Is Seamless Layer Replacement Possible in ArcGIS Notebooks?

Question

Hello everyone, I'm quite new to ArcGIS Notebooks and my understanding of them is quite basic.

Is it possible to use ArcGIS Notebooks to seamlessly replace the old layer in Arcgis online maps with a new one, while keeping all my labels and symbology intact and applied to the new layer?  The new layer will have all the same fields as the old one, plus a few extra.

AWESOME! Will try and report back so that the world can learn with me, haha.

ArcGIS Assistant should be able to solve this for you, it basically does the same thing as grabbing the JSON definition in a notebook or other Python script would do.  Just instead of manipulating the JSON definition via code or a text editor, you're manipulating it in the web browser.

Updating a joined view layer should be the same in theory as updating any other layer, there are two main properties to pay attention to, the Item ID and the URL.  I don't think there's anything else specific to joined layers you'd need to update, but I could be wrong...

As with the other approaches, I'd suggest doing this with a map you don't care about first, rather than one that's in use.  If you create a copy of one of your maps containing the join, that should be a good test case.

Hello Mr. Snake,

First, thank you for your response. Let me hit you with a follow-up question that you might know the answer to. In the post you linked me to in your original response, another person mentioned the use of the ArcGIS Assistant tool. I had honestly never heard of it before, but from my looking around at it, it appears to be able to directly edit the JSON of my ArcGIS Online web maps, which would allow me to swap out one feature layer for another.

However, I now feel like I should explain a little more of what my true problem is so that you might be able to inform me if the ArcGIS Assistant tool could assist me with my real problem. What I actually have in my maps is a joined hosted feature layer view, as depicted in the image attached to this message. My goal is to update several maps with a new joined feature layer view.

Given the specifics of my situation—aiming to replace an existing joined view layer in my maps with a newly created joined hosted feature layer view—do you believe ArcGIS Assistant can facilitate this transition?

Basically, I need to do this switching out of hosted feature layer views because I have added some new fields to one of the feature layers that are used in the joined feature layer view and because of this, I now have to make a new joined view, as you can't update a joined view. In my mind, it should work, but I just wanted to ask a pro before I gave it a shot to see what you would think :) .
