Python Toolbox: Issue saving an edited input parameter as a layer file
Hi there. This is a follow-on question from my previous post. If you would like more context, please visit the post here:
I have previously created a python toolbox script that will create a fishnet and select the cells that intersect a boundary defined by a parameter. Cells that do not intersect the boundary are deleted.
I now want to change the script so that the fishnet is not created in the script - instead it is defined as a parameter. Following this, I want the script to select the cells that intersect the boundary and then save them as a new layer file. param0 is defined as the boundary and param1 as the fishnet. The script looks like this:
# -*- coding: utf-8 -*-
import arcpy
class Toolbox(object):
def __init__(self):
self.label = "Toolbox"
self.alias = "toolbox"
# List of tool classes associated with this toolbox
self.tools = [Tool]
class Tool(object):
def __init__(self):
self.label = "Tool"
self.description = ""
self.canRunInBackground = False
def getParameterInfo(self):
# Param 0 = UK Boundary
param0 = arcpy.Parameter(
displayName="Input Feature Class",
name="Parameter0",
datatype="GPFeatureLayer",
parameterType="Required",
direction="Input")
param0.filter.list=["POLYGON"]
# Param 1 = Fishnet
param1 = arcpy.Parameter(
displayName="GRID",
name="Parameter1",
datatype="GPFeatureLayer",
parameterType="Required",
direction="Input")
params = [param0,param1]
return params
def isLicensed(self):
return True
def updateParameters(self, parameters):
return
def updateMessages(self, parameters):
return
def execute(self, parameters, messages):
# Overwrite existing file of the same name
arcpy.env.overwriteOutput = True
# Reference Parameters
input1 = parameters[0].valueAsText
inputgrid1 = parameters[1].valueAsText
# Convert inputgrid1 to feature class
arcpy.management.MakeFeatureLayer(inputgrid1,"inputgrid1_lyr")
# Select by Location
arcpy.management.SelectLayerByLocation("inputgrid1_lyr", "INTERSECT", input1, None, "NEW_SELECTION", "NOT_INVERT")
# Save to layer file
arcpy.management.SaveToLayerFile(inputgrid1,"NewGrid.lyr")
return
Upon completion of the script, I receive no errors. However, no new layer file (NewGrid.lyr) appears in my geodatabase. I have a feeling that the solution here is simple - so apologies in advance for my poor understanding of Python toolboxes. Is anybody able to offer any guidance?
