Script works in python win but does not in al toolbox within ArcMAP

Anonymous User

Original User: af.ramirez

Hi everybody...

I've been developing a quite long script, and I tested it in PyScripter an IDLE when it was finished.... well it works perfectly, so I added it to a toolbox in ArcMAP and when I ran it it did not work....

I have spent many days trying to figure out what the problem is but until now it has been imposible...

This is a piece of the code where the error comes out...

print "Startin iterations"
    print datetime.datetime.now()
    fields= ("FID", "avg_mindis", "I_conc", "Max_lenght","TamanoTerr")
    ##create UpdateCursor and iterate trough each register
    with arcpy.da.UpdateCursor(territory, fields) as cursor:
        for row in cursor:
            currentID= row[0]
            #print currentID
            ## select current cell with current FID
           where= " FID = " + str(currentID)
            arcpy.SelectLayerByAttribute_management(territory_lyr, "NEW_SELECTION", where )
            arcpy.SelectLayerByLocation_management(eventos_lyr, "INTERSECT", territory_lyr, "" , "NEW_SELECTION")

I don't know if maybe there is a problem with the selection by attributes...

Appreciate any help..

Hi Felipe, can you describe the error that you get? Are you using any error handling?

Andres_FelipeRamirez_Mejia

Hi....

I have a try - Except sentence starting before this line with arcpy.da.UpdateCursor(territory, fields) as cursor:

and the error I get is this

hmm, if you import the sys and traceback modules, you can add this code in the except statement:

tb = sys.exc_info()[2]
tbinfo = traceback.format_tb(tb)[0]
pymsg = "PYTHON ERRORS:\nTraceback Info:\n" + tbinfo + "\nError Info:\n     "\
                + str(sys.exc_type) + ": " + str(sys.exc_value) + "\n"
msgs = "ARCPY ERRORS:\n" + arcpy.GetMessages(2) + "\n"
print pymsg
print msgs

Hopefully you can get more detailed information about what's going on.

Hi Adam...

I added the code you gave me and the new nessages didn't show new info about what's going on...

look at the messages...

Ok, I don't know the earlier parts of your code, but perhaps there is an issue with how you are creating the layers and/or getting them from the tool parameters... assuming you are running it through a tool dialogue box. It may also have to do with the parameter types you are using in the dialogue box. Can you pass that information along?

Hi Adam...

Here is an example of the code...with some modifications

import arcpy
import datetime
import os
import sys
import traceback
arcpy.env.overwriteOutput = True

territory= arcpy.GetParameterAsText(0)
path= arcpy.GetParameterAsText(1)

arcpy.MakeFeatureLayer_management(territory,"territory_lyr")
fldFID = arcpy.Describe(territory).OIDFieldName
print "ID: "+fldFID
fields= (fldFID, "avg_mindis", "I_conc", "Max_lenght","TamanoTerr")

try:
    with arcpy.da.UpdateCursor(territory, fields) as cursor:
        for row in cursor:
            currentID = row[0]
            where = "{0}={1}".format(arcpy.AddFieldDelimiters(territory, fldFID), currentID)
            print "where: "+where
            arcpy.SelectLayerByAttribute_management("territory_lyr", "NEW_SELECTION", where)
            print "Selection ok"
except Exception as e:
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    pymsg = "PYTHON ERRORS:\nTraceback Info:\n" + tbinfo + "\nError Info:\n     "\
                    + str(sys.exc_type) + ": " + str(sys.exc_value) + "\n"
    msgs = "ARCPY ERRORS:\n" + arcpy.GetMessages(2) + "\n"
    print pymsg
    print msgs

and the error is....[ATTACH=CONFIG]31637[/ATTACH]

I may have found the error: in the code you posted, you need to have "territory_lyr" as the first parameter in AddFieldDelimiters, right now you have the territory string, so that is probably causing an issue with the query. It would be good to use "territory_lyr" in the Describe method as well.

Andres_FelipeRamirez_Mejia

Hi Adam...

I tried the things you suggested but the didn't work...

The same error message comes out...

I don't know what else I can do....

Well, you could rework the code so you don't have to use SelectByAttribute. This could work provided that the where clause is not the problem:

territory= arcpy.GetParameterAsText(0)
path= arcpy.GetParameterAsText(1)

arcpy.MakeFeatureLayer_management(territory,"territory_lyr")
fldFID = arcpy.Describe(territory).OIDFieldName
print "ID: "+fldFID
fields= (fldFID, "avg_mindis", "I_conc", "Max_lenght","TamanoTerr")

try:
    with arcpy.da.UpdateCursor("territory_lyr", fields) as cursor:
        for row in cursor:
            currentID = row[0]
            where = "{0}={1}".format(arcpy.AddFieldDelimiters("territory_lyr", fldFID), currentID)
            print "where: "+where

            #instead of making selection, just create a new feature layer using the where clause
            arcpy.MakeFeatureLayer_management("territory_lyr","territory_lyrSELECT",where)

            #arcpy.SelectLayerByAttribute_management("territory_lyr", "NEW_SELECTION", where)
            print "Selection ok"

You could try casting the currentID as a string, though it seems redundant at this point.
