我试图用arcpy游标主持的特点re layer containing a geodatabase with multiple tables and feature classes. After digging around the internet, a few posts seem to allude that I can do this: https://gis.stackexchange.com/questions/363932/how-can-i-use-updatecursor-in-agol-layers //www.gamepadva.com/t5/arcgis-api-for-python-questions/updatecursor-with-a-hosted-table/td-p/781002 Whereby, it seems the process is to: Access ArcGIS Online account Search for the hosted feature layer in my content Use the URL for the item as the first parameter in the arcpy cursor (i.e. arcpy.da.SearchCursor(item.url, fields)) Run Cursor So, code looks something like this: from arcgis.gis import GIS import arcpy gis = GIS("https://www.arcgis.com", "username", "password") hfl = gis.content.get('itemitd') url = hfl.tables[8] with arcpy.da.SearchCursor(url, '*') as cursor: for row in cursor: print(row) Which returns the following error: RuntimeError: cannot open 'https://services6.arcgis.com/yadda/arcgis/rest/services/nameofhostedfeaturelayer/FeatureServer/10' I tried using a slightly different approach to grab the item, but is pretty much the same as the above: hfl = gis.content.search(query="title:nameofhostedfeaturelayer, owner:username", max_items=1000) url = hfl[0].tables[8].url with arcpy.da.UpdateCursor(url , "*") as cursor: for row in cursor: row[0] = "hello" cursor.updateRow(row) Which yields the same error. Couple notes: I own the data It is shared to a few groups, but not publicly I've allowed edits on the hosted feature layer and any other setting that may or may not allow the script to see and read the hosted feature layer It appears I do have access to the hosted feature layer and I can perform other operations on it such as printing out items or values: for v in hfl.values(): print(o) for i in hfl.items(): print(c) Any suggestions why I am receiving that error? ...

I created a polygon feature class in ArcGIS Pro that contains 3 text fields. I added a 2 simple Attribute Rule to two of the fields. One that just adds 2+3 when a new feature is added or an existing feature is updated and then one that jsut concatenates 2 strings together (i.e. "My" + "_test"). I validated each rule and both past validation. The tested the rules in ArcGIS Pro by adding a new record and they work. The first field updates the calculated value (5) automatically when the feature is added and the second field concatenates the strings. Same thing when the feature is edited. My purpose was to see if those attribute rules carry over into ArcGIS Online, so I published the geodatabase containing the feature class as a hosted feature layer into AGO. I enabled editing on the settings of the hosted feature layer and then added it to a map. I tried editing the layer in the map by clicking the 'Edit' button on the layers properties and then choose 'Add a New Feature' and tried clicking in the map to start drawing a new polygon. At this point the map freezes up and won't allow me to start drawing. In the image below, you can see I have editing enabled, but when I hover my cursor in the map and start clicking, nothing happens. When I try to scroll around in the map, it won't. It just freezes. I tested the above in the new Map Viewer. I went on to test in the old map viewer and it will allow me to add a feature, however the attribute rules don't update the fields that are applied to. So, question. Should attribute rules work in ArcGIS Online? If so, why is the new map viewer freezing? Why don't they seem to work in the old map viewer when I add or edit a feature? If I add a feature class with no attribute rules, I don't have an issue adding features in either map viewer. ... View more
