list map name that is reference to a layout in arcgis pro project
Accepted Solutions
Wait I think I figured it out.
I dug into my testing projects a little more to see where the error was occuring.
Specifically, it always occurred on the same Layout out of the four in the project.
I checked the layout, and guess what? The dataframe isn't referencing any map. Not sure when or how that happened, but here we are.
For some reason, I couldn't get it to tell me straight out if it wasn't referencing anything.
So I ended up just making the whole thing a try/except.
import arcpy
mapDict= {}
errorList = []
aprx = arcpy.mp.ArcGISProject("CURRENT")
for lyt in aprx.listLayouts():
#Filter down the list to only map frames
for m in lyt.listElements("MAPFRAME_ELEMENT"):
try:
if lyt.name in mapDict:
#You want the name of the map in map frame, not the map frame itself
mapDict[lyt.name].append(m.map.name)
else:
mapDict[lyt.name]=[m.map.name]
except:
errorList.append(lyt.name)
print(mapDict, "\n")
print("The following layouts had errors. \n"
"Check to see if their map frames are referencing a map.",
"\n".join(errorList))
'''Results'''

import arcpy
import csv
import pandas as pd
mapList= []
errorList = []
# Enter in the properties you care about
propList= ['brightness', 'visible', 'isBroken']
outCSV = r'W:\Downloads\testing.csv'
aprx = arcpy.mp.ArcGISProject("CURRENT")
for lyt in aprx.listLayouts():
# Filter down the list to only map frames
for m in lyt.listElements("MAPFRAME_ELEMENT"):
try:
for lay in m.map.listLayers():
# Ignore group and base layers
if lay.isGroupLayer is True:
continue
if lay.isBasemapLayer is True:
continue
tempList= [lyt.name, m.map.name, lay.name]
for prop in propList:
#print(getattr(lay, prop,""))
tempList.extend([getattr(lay, prop,"")])
mapList.append(tempList)
except:
errorList.append(lyt.name)
with open(outCSV, 'w', newline='') as file:
writer = csv.writer(file)
heading = ["Layout", "Map", "Layer"]
heading.extend(propList)
writer.writerow(heading)
writer.writerows(mapList)
#Delete duplicates.
print("Deleting duplicates")
df = pd.read_csv(outCSV)
# This way drops any duplicate maps, leaving only the entries
# for the first layout in which they appear.
df= df.drop_duplicates(subset=heading[1:])
# This one just drops duplicates
#df= df.drop_duplicates()
df.to_csv(outCSV)
print("done")
if len(errorList)>0:
print("The following layouts had errors. \n"
"Check to see if their map frames are referencing a map.",
"\n".join(errorList))
This ought to do it.
It'll print out an excel sheet (file path in Line 9) containing the following columns: Layout, Map name, Layer name, and then whatever properties you want, as entered into propList (Line 8 )(don't worry about the name, that goes in by default).
The end result looks like this.
As presented right now, it also gets rid of duplicate entries for maps. To ignore this and list all maps, regardless of how many times they appear, just comment out Line 43 and un-comment Line 45.
If you're interested in just one layout, you can filter it down in Line 12, e.g. aprx.listLayouts('Layout 1')
Hope this helps!
