[GIS] Zoom to selected feature, without using ‘current’ in ArcPy

arcpygeoprocessingpythonselect

I am wondering if it is possible to build a zoom to geoprocessing service without using 'current' for the MXD variable in Python? Using 'current' my tool works in ArcMap, but not in my geoprocessing service.

Here is my code that work fine locally in ArcMap:

import arcpy


MXD=arcpy.mapping.MapDocument('current')    
dataframe = arcpy.mapping.ListDataFrames(MXD, "Web Mercator")[0]   
dataframe.zoomToSelectedFeatures() 
arcpy.RefreshActiveView()

When I publish my service, the zoom feature no longer works. I have read online that you can't use 'current' in a geoprocessing service, that's fine. When I enter the path to the MXD, the zoom function no longer works.

I think you need to set the path to your map - CURRENT only works if you're in ArcMap.

MXD=arcpy.mapping.MapDocument(r'C:\data\new.mxd')

I googled around and I suppose you are basing off of some code found here: http://resources.arcgis.com/en/help/main/10.1/index.html#//00s30000004p000000

You'll notice that the code is slightly different with nesting the if statements and especially the location of mxd.save(). That is likely your problem unless you are using their code and I'm looking at a copy-paste formatting error. If the first if statement fails, the second one is still evaluated, which isn't what you want.

Before finding that, I wrote this:

import os, arcpy

folderPath = "G:\GIS\Services\Test"
for fileName in [x for x in os.listdir(folderPath) if os.path.splitext(x)[1] == ".mxd"]:
    fullPath = os.path.join(folderPath, fileName)
    if os.path.isfile(fullPath):          
        mxd = arcpy.mapping.MapDocument(fullPath)
        print "MXD: " + fileName
        arcpy.env.workspace = fullPath            
        mxd.replaceWorkspaces("", "NONE", r"Database Connections\Connection to gisserver.sde","SDE_WORKSPACE")        

        mxd.save()
        del mxd
    else:
        print "error! {0} failed to be replaced".format(fullPath)
print "successfully changed data sources"

I haven't tested it, but it should work.

[GIS] Arcpy zoom to selected features not working

Your code is not actually selecting anything, you are making a subset view of your data with the MakeFeatureLayer tool.

You need to run the selectbyattribute tool on your layer.

The desktop help suggests if you want to zoom to selected features in a specific layer you should use this code:

df.extent = lyr.getSelectedExtent()
