Can't figure this one out. I'm trying to replace a layer's datasource based on a user-input parameter (not shown in the code snippet). I know the SDE path that gets created (BasinPath variable) is correct because I've tested it using other try/except statements. Anyone familiar with this tool? I'm using 10.6. The try/except statement beginning on line 13 is the part that isn't working.
def zoomTo(info, bas):
doc = arcpy.mapping.MapDocument("Current")
dataFrame = arcpy.mapping.ListDataFrames(doc)
MapLayers = arcpy.mapping.ListLayers(doc,"statewide_irr",dataFrame)
Layer = MapLayers
DNRPrd = "D:\\WID\\WID_SDE.sde"
IRR = DNRPrd + "\\" + "WID_SDE.Irr"
BasinPath = IRR + "\\" + "WID_SDE.Irr_" + str(bas)
for layr in arcpy.mapping.ListLayers(dataFrame):
if layr.name == "statewide_irr":
layr.replaceDataSource(BasinPath, "SDE_WORKSPACE", "statewide_irr", True)
errorMsg = "Error in dataSourceReplace"
pythonaddins.MessageBox(errorMsg, 'Shucks!', 0)
