Using SOI to add fields

AlexGunko — Wed, 13 Jan 2016 07:26:43 GMT

Hey, I was wondering if it possible to use SOI to add fields to a layer in a map server.

I know I can add attributes to graphics, but I need to add a field for fillter expression.

If it matters, I develop the SOI in .Net

Thanks.

HI Alex can you give further details ? SOIs can pre and post process request Server Object so you can do filter/query a field not exposed via rest from arcgis server

Hey, I want to add a field with an SOI, I mean like, when someone access the map server (e.g access the url "http://server.domain/arcgis/rest/MyMapServer/MapServer/0"), the SOI checks if a specific field is exists in the following layer and if it's not, then add it to the layer. That way when I want to export the map server with a filter expression, I can filter it with the new field.

Thanks.

if a field isn't exposed in a layer of service you can do a soi that filter in feature class underlying of layer and return a export filtered. If you want expose a field of feature class permanent (not visible when you have published service) you need a edit service and restart service using rest admin api

Hey, let me describe my problem in a different way. I have a map server that displays data about house locations from a database, and every house has an unique ID. I have an external service that gives me extra details about each house. What I would like to do is joining the data from the database and the external service and display it in the client side. I know I can can code it in javascript, etc. But I would like that it will happen in the server side (e.g an SOI that will do that).

Thanks!

you have a post process Server Object (your query from client). You combine this json with json from your external service using library JSON.NET and send to client

Hi,

Will you be able to provide a sample SOI on the below please. Thank you.

if a field isn't exposed in a layer of service you can do a soi that filter in feature class underlying of layer and return a export filtered.
