I would like to use ArcGIS Python API (v. 1.4.1) to copy the operational layers from one map to another in the same 10.6 Portal (for a development map / production map environment where I make changes to the development maps' symbology, layers, popups, etc., and then just copy the entire operational layers object to the production map), but I can't get it to work (even though it worked on a previous version of the API / previous version of Portal). Here is my old code, which worked in a previous version. In this version, the code successfully runs, but the destination map isn't changed. from arcgis . gis import GIS from arcgis . gis import Item import arcgis . mapping portal = GIS ( " https://portalurl/webcontext " , "username" , "password" , verify_cert = False ) srcMap = Item ( portal , "5959197ba01748ccb51cf097597b4cf4" ) destMap = Item ( portal , "e326e343d5aa45668a448e54acc4d06d" ) opsLayers = srcMap . get_data ( ) [ 'operationalLayers' ] mapDestObj = arcgis . mapping . WebMap ( destMap ) mapDestObj [ 'operationalLayers' ] = opsLayers mapDestObj . update ( ) I've also followed instructions located at Using and updating GIS content | ArcGIS for Developers , but that doesn't seem to work either. mapDestObj has a layers attribute, but mapDestObj.layers = opsLayers throws an AttributeError (can't set attribute) I've also tried the following: which successfully updates the mapDestObj.layers attribute, but doesn't save the map when I run the update command. for index , layer in enumerate ( mapDestObj . layers ) : mapDestObj . layers [ index ] = opsLayers [ index ] webMapObj . update ( { } ) Does anyone have a working prototype for this workflow?

Jay Gregory, in your first snippet, you may have to change the last but one line to the following # your current line # mapDestObj['operationalLayers'] = opsLayers mapDestObj . definition [ 'operationalLayers' ] = opsLayers mapDestObj . update ( ) and that should work. Can you give this a try and let me know?

Copy operational layers object from one web map to another

I would like to use ArcGIS Python API (v. 1.4.1) to copy the operational layers from one map to another in the same 10.6 Portal (for a development map / production map environment where I make changes to the development maps' symbology, layers, popups, etc., and then just copy the entire operational layers object to the production map), but I can't get it to work (even though it worked on a previous version of the API / previous version of Portal).

Here is my old code, which worked in a previous version.

In this version, the code successfully runs, but the destination map isn't changed.

I've also followed instructions located at Using and updating GIS content | ArcGIS for Developers , but that doesn't seem to work either.

mapDestObj has a layers attribute, but mapDestObj.layers = opsLayers throws an AttributeError (can't set attribute)

I've also tried the following: which successfully updates the mapDestObj.layers attribute, but doesn't save the map when I run the update command.

<SPAN class="keyword token">for</SPAN> index<SPAN class="punctuation token">,</SPAN> layer <SPAN class="keyword token">in</SPAN> enumerate<SPAN class="punctuation token">(</SPAN>mapDestObj<SPAN class="punctuation token">.</SPAN>layers<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>

Does anyone have a working prototype for this workflow?

Jay Gregory, in your first snippet, you may have to change the last but one line to the following

<SPAN class="comment token"># your current line</SPAN>
<SPAN class="comment token"># mapDestObj['operationalLayers'] = opsLayers‍</SPAN>
mapDestObj<SPAN class="punctuation token">.</SPAN>definition<SPAN class="punctuation token">[</SPAN><SPAN class="string token">'operationalLayers'</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="operator token">=</SPAN> opsLayers‍
mapDestObj<SPAN class="punctuation token">.</SPAN>update<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN>‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

and that should work. Can you give this a try and let me know?

You are welcome. For future reference, the correct way to do your workaround is to pass a dictionary with key= "text" and value = your web map dict. So the last line should look like this

<SPAN class="keyword token">import</SPAN> json
destMap<SPAN class="punctuation token">.</SPAN>update<SPAN class="punctuation token">(</SPAN>data<SPAN class="operator token">=</SPAN><SPAN class="punctuation token">{</SPAN><SPAN class="string token">'text'</SPAN><SPAN class="punctuation token">:</SPAN>json<SPAN class="punctuation token">.</SPAN>dumps<SPAN class="punctuation token">(</SPAN>destData<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Thanks - that worked! It seems like the definition attribute isn't listed in the documentation.

Also, I was able to get the operation to work by doing the following:

srcData = srcMap.get_data()
destData = destMap.get_data()
destData['operationalLayers'] = srcData['operationalLayers']
destMap.update(data=str(destData))
