Update Service Definition on AGOL

InyoCounty — Fri, 05 Jan 2018 21:59:35 GMT

Using the script at this blog: https://blogs.esri.com/esri/arcgis/2017/03/14/updating-your-hosted-feature-services-with-arcgis-pro-and-the-arcgis-api-for-python/

Line 41: sdItem = gis.content.search("{} AND owner:{}".format(sd_fs_name, user), item_type="Service Definition")[0]
returns the wrong Service Definition (SD). The title query is not strict enough, so it returns any SD with a "Z" in the title. The SD I'm looking for is Zoning.

Title or owner can be replaced with id:
sdItem = gis.content.search(query="title:"+ sd_fs_name + " AND id:" + serviceItemID, item_type= "Service Definition")[0]
which throws: IndexError: list index out of range

Many permutations have been tried for using ID.

If item_type= "Service Definition" is removed, line 41 will run:
sdItem = gis.content.search(query="title:"+ sd_fs_name + " AND id:" + serviceItemID)[0]

However, then on line 45: fs = sdItem.publish(overwrite=True)
it throws:
File “C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis.py”, line 3125, in publish
if fileType == ‘shapefile’:
UnboundLocalError: local variable ‘fileType’ referenced before assignment

So, the question is - how do I specify the ID, and also specify the item type?

A query like the following should work

type:"Service Definition" id:b7ec249e81b7405bd5322adee43d8feb

There isn't really a need to specify the type and the id though, since the item id alone is unique.

The following both return the same item.

sdItem = gis.content.search('type:"Service Definition" id:b7ec249e81b7405bd5322adee43d8feb')[0]

sdItem = gis.content.search('id:b7ec249e81b7405bd5322adee43d8feb')[0]

Thanks Aaron,

There's still the problem that the line gis.content.search won't run if type is specified, but if type is not specified then the sdItem.publish errors out.

Here is the error for including both type and id, as formatted in your response, with the one difference of passing in the id as a variable:

It sounds like the query you are creating is returning no items. The search function returns a list of items. Since no items are returned, and you are accessing it via an index of 0, you get the "list index out of range error".

The itemId you need to specify should be the item id of the service definition file on AGOL, not the id of the published service. Can you verify the item id points to a service definition file on AGOL?

That was it! The ID that was being passed in was for the feature layer, not the service definition. Thanks Aaron!

Could you post what the final code looks like? Thanks!
