AddCodedValueToDomain 示例(Python 窗口)

以下 Python 窗口脚本演示了如何在立即模式下使用 AddCodedValueToDomain 函数。

import arcpy from arcpy import env env.workspace = "C:/data" arcpy.AddCodedValueToDomain_management("montgomery.gdb", "material", "1", "PVC")
AddCodedValueToDomain 示例 2(独立脚本)

此独立脚本将 AddCodedValueToDomain 函数用作工作流的一部分,以创建属性域并为其赋值。

# Name: MakeDomain.py # Description: Create an attribute domain to constrain pipe material values # Author: ESRI    #Import system modules import arcpy from arcpy import env   try:     # Set the workspace (to avoid having to type in the full path to the data every time)     env.workspace = "C:/data"       # Set local parameters     domName = "Material4"     gdb = "montgomery.gdb"     inFeatures = "Montgomery.gdb/Water/Distribmains"     inField = "Material"       # Process: Create the coded value domain     arcpy.CreateDomain_management("montgomery.gdb", domName, "Valid pipe materials", "TEXT", "CODED")          #Store all the domain values in a dictionary with the domain code as the "key" and the      #domain description as the "value" (domDict[code])     domDict = {"CI":"Cast iron", "DI": "Ductile iron", "PVC": "PVC", \                 "ACP": "Asbestos concrete", "COP": "Copper"}          # Process: Add valid material types to the domain     #use a for loop to cycle through all the domain codes in the dictionary     for code in domDict:                 arcpy.AddCodedValueToDomain_management(gdb, domName, code, domDict[code])          # Process: Constrain the material value of distribution mains     arcpy.AssignDomainToField_management(inFeatures, inField, domName)   except Exception, e:     # If an error occurred, print line number and error message     import traceback, sys     tb = sys.exc_info()[2]     print "Line %i" % tb.tb_lineno     print e.message
