I'm trying to write a script that allows me to look through map documents and replace each layer's data source in each map document. Everything is working logically I believe, and all my loops are working as they should. The datasets that are referenced exist. Yet, I am getting this error :
Traceback (most recent call last): File "C:\Python27\ArcGIS10.1\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 326, in RunScript exec codeObject in main.dict File "C:\Users\Daimon Nurse\Desktop\DFMPROJECT\Scripts\editmapdocument8.py", line 18, in Lyr.replaceDataSource(workspace_path, workspace_type, dataset_name) File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\utils.py", line 181, in fn_ return fn(*args, **kw) File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy_mapping.py", line 680, in replaceDataSource return convertArcObjectToPythonObject(self._arc_object.replaceDataSource(*gp_fixargs((workspace_path, workspace_type, dataset_name, validate), True))) ValueError: Layer: Unexpected error
This is the code I am using:
import arcpy import os PATH2 = r"C:\Users\Daimon Nurse\Desktop\DFMPROJECT" arcpy.env.workspace = PATH2 arcpy.env.overwriteOutput=True for file in arcpy.ListFiles("*.mxd"): filePath = os.path.join(PATH2,file) MapDoc = arcpy.mapping.MapDocument(filePath) lyrList = arcpy.mapping.ListLayers(MapDoc) i = 1 for Lyr in lyrList: print Lyr workspace_path = r"C:\Users\Daimon Nurse\Desktop\DFMPROJECT\DFM" workspace_type = "FILEGDB_WORKSPACE" dataset_name = 'Zone{0}'.format(i) print dataset_name print workspace_type print workspace_path print os.path.join (workspace_path, dataset_name) Lyr.replaceDataSource(workspace_path, workspace_type, dataset_name) i = i + 1 These are the printed results on the first iteration for dataset_name, workspace_type, workspace_path and os.path.join respectively:
