Layer.replaceDataSource

MaciekFertala1

Hi,
I'm trying to change layer data source from one shape file to another in different workspace (directory).

mxd = arcpy.mapping.MapDocument(r"Z:\02_GIS\Project\mxd\P01.mxd")
print "mxd"
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyrfile = arcpy.mapping.Layer(r"Z:\Maps\GIS_utilities\python_script\lyr\_kabel.lyr")
print lyrfile.workspacePath # old path
lyrfile.replaceDataSource(r"Z:\02_GIS\Project\wektor", "SHAPEFILE_WORKSPACE", "P01_RIVER.shp")

But this way its not working. What should I change?

Thanks form help,
MF

according to Jake note this script work fine for me:

import arcpy, os, sys

from arcpy import env

env.workspace = r"F:\Projects\Nadav\gany_tikva\gis"

for mxdname in arcpy.ListFiles("*.mxd"):

    print mxdname

    mxd = arcpy.mapping.MapDocument(r"F:\Projects\Nadav\gany_tikva\gis\\" + mxdname)

    df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]

    for lyr in arcpy.mapping.ListLayers(mxd, "*", df):

        if lyr.name == "50000.sid":

           

            # very importent that "RASTER_WORKSPACE" will change according to

            # the data we want to replace

           

            lyr.replaceDataSource(r"F:\GIS\topo_50000", "RASTER_WORKSPACE", "50000.sid", True)

            print 'replaceDataSource'      

    mxd.save()

del mxd
