[GIS] Runtime error : ‘unicode’ object is not callable

arcpypython

I'm working on a script to replace a layer datasource, and I'm getting an error I cannot figure out.

When I run the following code in a python window inside ArcMap, I get a "Runtime error : 'unicode' object is not callable"

import arcpy
mxd = arcpy.mapping.MapDocument ("CURRENT")
for lyr in arcpy.mapping.ListLayers(mxd):
     if lyr.supports("DATASOURCE"):
         if lyr.dataSource (r"N:\3_PLANNING\6_GIS\GIS Data\INDIANA GIS\Indiana_County.mdb\Boundaries\Indianacounty_shp"):
             lyr.replaceDataSource (r"N:\3_PLANNING\6_GIS\GIS Data\Indiana_County_Database_201201.gdb", "FILEGDB_WORKSPACE", r"N:\3_PLANNING\6_GIS\GIS Data\Indiana_County_Database_201201.gdb\Boundaries\County_Boundary")

Problem is, I'm not very good at python yet, and I'm not sure what the unicode object is that the error is referring to.

Turns out the issue was:

if lyr.dataSource (r"N:\3_PLANNING\6_GIS\GIS Data\INDIANA GIS\Indiana_County.mdb\Boundaries\Indianacounty_shp"):

it should be:

if lyr.dataSource == "N:\3_PLANNING\6_GIS\GIS Data\INDIANA GIS\Indiana_County.mdb\Boundaries\Indianacounty_shp":

Works fine for me at 10.1. I made a slight modification (other than the obvious configuration variable changes) for the case when the Layer.datasetName property is not supported:

#Select map
map_path = r"C:\GISData\BloomfieldTownship\BloomfieldTownship.mxd"

#define dictionary

PathDict = {
    "SiteAddress": r"C:\GISData\BloomfieldTownship",
    "RoadCenterline": r"C:\GISData\BloomfieldTownship",
    "SchoolTaxDistrict": r"C:\GISData\BloomfieldTownship"}

import arcpy

mxd = arcpy.mapping.MapDocument(map_path)

for df in arcpy.mapping.ListDataFrames(mxd):
    for lyr in arcpy.mapping.ListLayers(mxd,"",df):
        layername = lyr.datasetName if lyr.supports("datasetName") else ""
        if layername in PathDict.keys():
            new_path = PathDict[layername]
            lyr.replaceDataSource(new_path,"SHAPEFILE_WORKSPACE", layername)
            if lyr.workspacePath == new_path:
                print "Workspace path for " + layername + " is updated."
            else:
               print "Path not updated for " + layername
mxd.save()
print "Map Saved"
del mxd

[GIS] AttributeError with unicode object with data frame in python script

The problem with the code you have is that you are trying to convert an ArcMap Map Document into into a string and then you supply the string for the arcpy.mapping.ListDataFrames function. I usually handle this by:

1) Using the ArcMap Document data type for the input parameter. enter image description here

2) Referring to the mxd file path as an Map Document object.

 mxd_raw = arcpy.GetParameterAsText(0) 
 mxd = arcpy.mapping.MapDocument(mxd_raw)

Your code after you've got access to the map document object could be:

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

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