Arcpy - Enregistrer la couche NA dans la classe d'entités

Question

Je suis en train de mettre à jour certains anciens outils et modèles de 9.3 à 10.3 et j'ai rencontré un problème en essayant d'enregistrer une couche spécifique dans un calque d'analyse réseau.

ci-dessous la copie de mon script et l'erreur qu'il génère:

arcpy.CheckOutExtension("Network") 
arcpy.env.workspace = r"C:\aaa\response profile\test.gdb" 

inNetworkDataset = "J:\\projects\\netmodels\\roadnetwork\\Vic_HERE_2014_Q2\\Data\\HERE_COREMAP.gdb\\RoutingApplication\\RoutingApplication_ND" 
outNALayerName = "StationOfInterest" 
allFacilities = r"C:\aaa\response profile\RMN.gdb\RNM_Statewide_Fire_Stations" 
facilitiesQuiery = "not occ_type = 'future fire station' and label in ('Springvale')" 
arcpy.MakeFeatureLayer_management(allFacilities,"inFacilities", facilitiesQuiery) 
outLayerFile = r"C:\aaa\response profile" + "\\" + outNALayerName + ".lyr" 
timeBreaks = 30 
print "varibles set" 

SA_result_object = arcpy.na.MakeServiceAreaLayer(inNetworkDataset, outNALayerName, 
            "EmergencyServicesTime", "TRAVEL_FROM", timeBreaks, 
            "NO_POLYS", "NO_MERGE", "RINGS", "TRUE_LINES") 
print "Service Area layer created" 

#Get the layer object from the result object. The service layer can now be 
#referenced using the layer object. 
SA_layer_object = SA_result_object.getOutput(0) 

#Get the names of all the sublayers within the service area layer. 
SAClassesIn = arcpy.na.GetNAClassNames(SA_layer_object,"INPUT") 
SAClassesOut = arcpy.na.GetNAClassNames(SA_layer_object,"OUTPUT") 
#Stores the layer names to use later 
facilitiesLayerName = SAClassesIn["Facilities"] 
print "facilitiesLayerName: " + facilitiesLayerName 
linesLayerName = SAClassesOut["SALines"] 
print "linesLayerName: " + linesLayerName 

arcpy.na.AddLocations(SA_layer_object , SAClassesIn["Facilities"], "inFacilities") 
print "added locations to layer" 
print "solving...." 
arcpy.na.Solve(SA_layer_object) 
print"solved" 

********** these are the lines that is causing me issues ********** 
linesSublayer = SA_layer_object.listLayers(SAClassesOut["Lines"])[0] 
arcpy.CopyFeatures_management(linesSublayer,"StationOfInterestLines") 

L'erreur que je reçois est:

linesSublayer = SA_layer_object.listLayers(SAClassesOut["Lines"])[0] 
AttributeError: 'Layer' object has no attribute 'listLayers' 

Toutes les idées ce qui est à l'origine, je fais mon la tête en essayant de le travailler. Merci

Read over the ListLayers documentation - il appelle un MXD en tant que paramètre et n'est pas utilisé comme attribut d'un objet Layer.

La syntaxe:

ListLayers (map_document_or_layer, {wildcard}, {data_frame}) 

Donc, vous voulez probablement quelque chose le long des lignes de:

linesSublayer = arcpy.mapping.ListLayers(SA_layer_object, "Lines")[0]
