I am creating a Python Toolbox. I have a RecordSet parameter. I'd like to be able to set the columns during the updateParameters method. It does not. parameter.columns is not settable outside of getParameterInfo
Is there a way to do this where I could? Here is a greatly simplified look at the problem.
import arcpy
class Toolbox(object):
def __init__(self):
self.label = "Toolbox"
self.alias = ""
self.tools = [Tool]
class Tool(object):
def __init__(self):
self.label = "Tool"
self.description = ""
self.canRunInBackground = False
def getParameterInfo(self):
param0 = arcpy.Parameter(
displayName="Column Names",
name="my_columns",
datatype="GPString",
parameterType="Required",
direction="Input")
param0.filter.list = ["ABC","XYZ"]
param1 = arcpy.Parameter(
displayName="Table",
name="my_table",
datatype="GPValueTable",
parameterType="Required",
direction="Input")
param1.columns = [['GPLong',"ID"],["GPString","A"],["GPString","B"],["GPString","C"]]
params = [param0,param1]
return params
def updateParameters(self, parameters):
if (parameters[0].altered and not parameters[0].hasBeenValidated):
if (parameters[0].value == "ABC"):
parameters[1].columns = [['GPLong',"ID"],["GPString","A"],["GPString","B"],["GPString","C"]]
else:
parameters[1].columns = [['GPLong',"ID"],["GPString","X"],["GPString","Y"],["GPString","Z"]]
return
def isLicensed(self):
return True
def updateMessages(self, parameters):
return
def execute(self, parameters, messages):
return
Thanks,
