I am new to GIS and pretty new to python, so sorry if this is ugly code.
I am creating a feature class in a postgres database if it does not already exist and the user wants it created.
That works fine, and adds a single layer to my table of contents in my current map. I added the line to change the privileges of the layer, and now I get a second polyline feature class added to the table of contents. Named a little different, and it does not stored in the database (the first, correct polyline does get stored). Where is this layer coming from, and how can I make it not show up?
is_there = False matched_layer = False for fc in arcpy.ListFeatureClasses(): regex = re.compile("skld_geodata\..+\.A%s" % sectional_name) if regex.match(fc): matched_layer = fc is_there = True if is_there is False: msg = 'No skld layer currently exists for this Arb. Would you like to create one?' create_input = pythonaddins.MessageBox(msg, 'Missing Layer', 4) # create a new geodatabase entry with the correct name if it does not already exist if create_input == 'Yes': arcpy.CreateFeatureclass_management(shp_path, arb_name, 'POLYLINE') # change the privileges for everyone to work with arcpy.ChangePrivileges_management(shp_path + "\\" + arb_name, "editor", "GRANT", "GRANT") else: geo_layer = arcpy.mapping.Layer(matched_layer) arcpy.mapping.AddLayer(self.df, geo_layer, "TOP")
I can add images of the table of contents if that makes it easier to understand what I am asking.
