Symbology Layer Not Applying to New Feature Layer

Question

So my custom tool script first creates a new feature layer based on an existing feature layer using the MakeFeature_management function with just the certain fields I want showing. After that, the tool has a variable called inputLayer = to the raw string of the newly created Feature Layer. Here's what the script looks like so far: import arcpy import arcpy.mapping as map mxd = arcpy.mapping.MapDocument("Current") visibleFields = ["Field1", "Field2", "Field3", "Field4", "Field5"] field_info = arcpy.Describe('Fiber Segments').fieldInfo df = arcpy.mapping.ListDataFrames(mxd)[0] for index in xrange(0, field_info.count): if field_info.getfieldname(index) not in visibleFields: field_info.setvisible(index,"HIDDEN") arcpy.Delete_management('Output Feature',"") arcpy.MakeFeatureLayer_management('Input Feature','Output Feature Layer',"","",field_info) addLayer = arcpy.mapping.Layer('Output Feature Layer') arcpy.mapping.AddLayer(df, addLayer) arcpy.RefreshTOC() arcpy.RefreshActiveView() inputLayer = r'Output Feature Layer' symbologyLayer = r'C:\pathway\Output Feature Layer symbology.lyr' arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ The issue here is that the symbology isn't applying to the Output Feature Layer when the entire script is run. If you run these lines individually in the python module in ArcMap, they run fine and apply the symbology. Any thoughts on this here?

Figured it out and here's the solution: import arcpy import arcpy.mapping as map mxd = arcpy.mapping.MapDocument("Current") visibleFields = ["Field1", "Field2", "Field3", "Field4", "Field5"] field_info = arcpy.Describe('Fiber Segments').fieldInfo df = arcpy.mapping.ListDataFrames(mxd)[0] for index in xrange(0, field_info.count): if field_info.getfieldname(index) not in visibleFields: field_info.setvisible(index,"HIDDEN") arcpy.Delete_management('Output Feature',"") arcpy.MakeFeatureLayer_management('Input Feature','Output Feature Layer',"","",field_info) addLayer = arcpy.mapping.Layer('Output Feature Layer') arcpy.mapping.AddLayer(df, addLayer) arcpy.RefreshTOC() arcpy.RefreshActiveView() inputLayer = arcpy.mapping.ListLayers(mxd, 'Output Feature Layer')[0] symbologyLayer = r'C:\pathway\Output Feature Layer symbology.lyr' arcpy.ApplySymbologyFromLayer_management (inputLayer, symbologyLayer)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This is working well for me without any errors. Not entirely sure why the raw string didn't work but the way it's set equal to inputLayer seems to do the trick.

Yes. I actually figured it out. I'll add that to the comments to show the solution.

Are all the field names and types matching between the .lyr file and the Input Layer?
