Ok, after hours trying to figure out what's going on with the "findAndReplaceWorkspacePath" I'm just giving up and reaching out for help. So far, I am thinking that this method provides completely unexpected/unstable/unreliable results. But before I get to far with my frustrations, I need somebody to review this code and let me know what I am doing wrong. The problem is that the workspace path of the layer files don't get re-pointed to the new SDE connection file, whether I use validate = True or False. When set to True the script crashes miserably, even though the connection file/parameters is valid, so it this example I set it to False, which you would expect to work, but it does not! This scripts loops through a root folder, recursively finds all the ".lyr" file under the root and re-points the workspacePath location. It can be executed in PythonWin/Idle or the ArcMap Python window, the results are the same i.e. unexpected/unstable/unreliable i.e. the layers don't get re-pointed.
import arcpy, sys, os, traceback, time, sys, random, string
root = r"D:\eaub490\repath_layers\DNR Map Layers\Forest Management"
for path, folders, fileList in os.walk(root):
print "*************\nFolder: " + path + "\n*************"
for f in fileList:
print f
if f.endswith(".lyr"):
lyr = arcpy.mapping.Layer(path + "\\" + f)
if lyr.isGroupLayer == False:
if lyr.supports("WORKSPACEPATH"):
if ".sde" in lyr.workspacePath:
workPath = lyr.workspacePath
print " * Old:", workPath
if lyr.isFeatureLayer:
workPathNew = r"D:\eaub490\repath_layers\sde_connections_read\ropa_v10.sde" # this is a valid connection file
lyr.findAndReplaceWorkspacePath("", workPathNew, False) # when validate = True then it becomes extremely unstable and unpredictable
else:
workPathNew = r"D:\eaub490\repath_layers\sde_connections_read\raster_v10.sde"
lyr.findAndReplaceWorkspacePath("", workPathNew, False)
lyr.visible = False # turn the visibility off
lyr.save() # save to v.10
if lyr.workspacePath <> workPathNew: # check because the findAndReplaceWorkspacePath does not always works
print " * Dang! the findAndReplaceWorkspacePath does not work:", lyr.workspacePath
else:
print " * New:", lyr.workspacePath
else:
print " * Not a SDE layer"
else:
print " * Workspacepath not supported"
else:
print " * Group layer, cannot be re-pathed" # as far as I know
else:
print " * Not a layer file"
print "\nEnd of program\n"
