update the html in 'custom attribute display' programatically using rest api python

Question

I need to loop each web map in ArcGIS online/portal and update the html for layers with  'custom attribute display'.

I am unable to get layers from web map.

from IPython.display import display
import arcgis
from arcgis.gis import GIS# connect to your GIS
gis = GIS("https://www.arcgis.com","arcgis_python","P@ssword123")
webmap_search = gis.content.search("Ebola maps", item_type="Web Map")
ebola_map_item = webmap_search[1]
ebola_map = WebMap(ebola_map_item)
for layer in ebola_map.layers: --- error: 'WebMap' object has no attribute 'layers'

print(layer.title) Is there any possibilities of updating HTML programmatically for all the layers in webmaps in Group.

Paresh Patel, you'll have to edit the web map object dictionary directly with the new HTML code, as opposed to editing the children dictionaries that are created as copies in your script. In version 1.2.3, index into the appropriate list item/dictionary value and set the description key equal to your html code, then call the web_map_object.update() method, which will send the update to the server. In version 1.3, obtain the definition dictionary of the web map object and edit accordingly, then pass the dictionary in to the web_map_object.update() method. Refer to the scripts below: With version 1.2.3 of the ArcGIS API for Python: from arcgis.gis import GIS from arcgis.mapping import WebMap gis = GIS("", "username", "password") search = gis.content.search('title:Test_html') wm = search[0] wmo = WebMap(wm) updated_html = "" wmo['operationalLayers'][0]['layers'][0]['popupInfo']['description'] = updated_html wmo.update() With version 1.3 of the ArcGIS API for Python: from arcgis.gis import GIS from arcgis.mapping import WebMap gis = GIS("", "username", "password") search = gis.content.search('title:Test_html') wm = search[0] wmo = WebMap(wm) updated_html = "" # get the definition dictionary of the web map object def_dict = wmo.definition # index into the appropriate layer and assign the update html as the popup def_dict['operationalLayers'][0]['layers'][0]['popupInfo']['description'] = updated_html # pass the updated definition dictionary into the web map object update method, boolean is returned wmo.update(def_dict)

Thank you Mani, I am able to get the current configure popupinfo using below code, but when I tried to update it back, it's not reflecting. I don't know where i am missing. from arcgis.gis import GIS from arcgis.gis import * from arcgis.mapping import WebMap, WebScene ago_gis = GIS(pPrtl_URL , pUserName , PPswrd) // Connecting Portal search_Results = ago_gis.content.search('title:Test_html',item_type='Web Map', max_items=1000, outside_org=False) // Search Web Map wm = search_Results[0] web_map_obj = WebMap(wm) lyrsdct = web_map_obj.layers[0] lyrobj = lyrsdct['layers'][0] popinfoObj = lyrobj['popupInfo'] popinfoObj['description'] // Able to display existing configured popinfoObj // I am assing html table popinfoObj['description'] = """

B
SUBBASIN	{SUBBASIN }
CGIA_FMS	{CGIA_FMS }
DWQ_INDEX_	{DWQ_INDEX_ }
DWQ_CLASS	{DWQ_CLASS }

""" web_map_obj.update // updating map object wm.update // updating web map

At the current version (1.3) the API the pop-up functionality is limited to giving you a basic pop-up that displays all the fields in a table.

But, if you know what needs to be put in the pup-up object, you can easily change the values and call the `update()` method. Since you are doing this on multiple web maps, I would recommend doing one using the web map UX (or ArcGIS Pro), read that maps definition (call the WebMap.definition or WebMap.layers property) to find the pop-up object and replicate that logic in all your maps.
