How to apply attribute table settings (fields visibility and format) from one layer to another using arcpy?

Sfortunatamente — Mon, 08 Sep 2025 10:29:25 GMT

I have 40 layers with the same table schema and I need to apply symbology and table settings from another layer. I have a template layer and applying symbology works as expected.

Is it possible to apply fields visibility and formats as well?

I can see pasteProperties (source_layer, {layer_paste_properties}) method but when applying in on a layer object I get the following error: AttributeError: 'Layer' object has no attribute 'pasteProperties'

L = map.addDataFromPath(r"..\Address.lyrx")
for lyr in map.listLayers():
print(lyr.name)
lyr.pasteProperties(L, layer_paste_properties="FIELD_PROPERTIES")

Thanks,

Layer—ArcGIS Pro | Documentation

you should check if it is a featurelayer before trying to try to pastProperties

isFeatureLayer
(Read Only)
Returns True if a layer is a feature layer.

Try this,

import arcpy # Load the template layer template_layer_path = r"..\Address.lyrx" template_layer = arcpy.mp.LayerFile(template_layer_path).listLayers()[0] # Get your map aprx = arcpy.mp.ArcGISProject("CURRENT") map = aprx.listMaps("Your Map Name")[0] # Apply symbology + field properties for lyr in map.listLayers(): if lyr.isFeatureLayer: print(f"Updating {lyr.name}...") arcpy.management.UpdateLayer(lyr, template_layer, True) # True = keep data source print(f"Completed: {lyr.name}") print("All layers updated successfully!")

Didn't work..

AttributeError: module 'arcpy.management' has no attribute 'UpdateLayer'

I'd just use the CIM definition object, since all these properties can be set directly using dictionaries/CIM objects:

from typing import Any from arcpy.management import MakeFeatureLayer from arcpy.cim.CIMVectorLayers import CIMFeatureLayer from arcpy.mp import ArcGISProject from arcpy._mp import Layer, Map def get_state(lyr: Layer) -> dict[str, Any]: layer_cim: CIMFeatureLayer = lyr.getDefinition('V3') states_to_save = [ 'snappable', 'selectable', 'visibility', 'expanded', 'labelVisibility', ] return {k:v for k, v in layer_cim.__dict__ if k in states_to_save} def apply_state(lyr: Layer, state: dict[str, Any]) -> None: if not lyr.isFeatureLayer: return layer_cim: CIMFeatureLayer = lyr.getDefinition('V3') layer_cim.__dict__.update(state) lyr.setDefinition(layer_cim)

The first function will pull states from a layer and the second will apply those states to a layer. In your case, you can put these in a loop for the map:

... def update_map_layers(mp: Map, state: dict[str, Any]) -> None: for layer in filter(lambda m: m.isFeatureLayer, mp.listLayers()): apply_state(layer, state) def main(): template_layer = MakeFeatureLayer(r'<path/to/template>.lyrx')[0] state = get_state(template_layer) project = ArcGISProject('<path/to/project>.aprx || CURRENT') mp = project.listMaps('<map_name>')[0] update_map_layers(mp, state) if __name__ == '__main__': main()

try

# Use ApplySymbologyFromLayer 
        arcpy.ApplySymbologyFromLayer_management(lyr, template_layer)
