Autolabel Feature Class Using a Relate

AlexeiB — Wed, 20 Aug 2014 04:20:25 GMT

Hello,

I have a feature class called FC1. I also have a Table called TBL1. The feature class and table are related using a 1-M relationship.

My question is as follows. Is there any way using ArcGIS Server 10.2.2 and ESRI JS to auto label my FC1 using all the related attributes from TBL1?

Example:

Feature Class: Kennel

Table: Dog

Relationship: KennelDogs

I want to have my kennels displayed on the map and autolabel each kennel with the dog's name. So the symbol for kennel 1 would have beside it DogName1, DogName2. Kennel 2 would have DogName3, DogName4, and DogName5.

Thank you,

Alex

Hi Alex,

Try below option, this option does not use relationship class, but labels a layer based on another feature class with 1:M relation. I have not tested this with publishing the layer to ArcGIS Server. I would expect it to work with ArcGIS Server as well.

Below is the expression code used.

import arcpy


def FindLabel ( [ROUTE_LINK_NO]  ):
  relateTable = r"C:\tempdelete\PL_TO_LINE.gdb\PL\VERT_TO_POINIT"
  returnFieldName = "POINT_M"
  joinFieldName = "ROUTE_LINK_NO"
  label = ""
  with arcpy.da.SearchCursor(relateTable, (returnFieldName), joinFieldName + " = " + [ROUTE_LINK_NO] ) as cursor:
   for row in cursor:
    label = label + str(row[0]) + ","
  return label
