Copy a hosted layer item

Learn how to use the portal service to create a new group in your portal, and add members to the group.

Prerequisites

You need an ArcGIS Location Platform, ArcGIS Online, or ArcGIS Enterprise account to use your portal.

Steps

Get the portal URL

To access a portal, you need an ArcGIS account which is associated with an organization that allows you to store and manage your content.

In a web browser, sign in to your portal with your ArcGIS account.
Identify the portal URL from the navigation bar. The base URL should be one of the following:
- ArcGIS Location Platform: https://www.arcgis.com/sharing/rest
- ArcGIS Online: https://www.arcgis.com/sharing/rest
- ArcGIS Enterprise: https://{machine.domain.com}/{webadaptor}/rest

Get an access token

To perform the portal service operation in this tutorial, you need an access token from OAuth 2.0 credentials. It is the only supported form of authentication. The use of API keys is not supported.

Go to the Create OAuth credentials for user authentication tutorial to get a set of OAuth 2.0 credentials.
Get an access token from the OAuth 2.0 credentials.
Copy the access token to your clipboard when prompted.

Set up environment

In a different window, launch Postman and create a blank request.

Copy a hosted layer item

Add the following import statement to your code.

main.py
Use dark colors for code blocks

from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection

Establish a connection to the portal using the GIS() module.

main.py
Use dark colors for code blocks

from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection

# Replace with your actual username, password, and item ID
username = 'your_username'
password = 'your_password'
feature_layer_item_id = 'your_feature_layer_item_id'  # The item ID of the item you want to copy
portal_url = 'https://www.arcgis.com'

# Authenticate with ArcGIS Online
gis = GIS(portal_url, username, password)

Get the item using the itemID.

main.py
Use dark colors for code blocks

from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection

# Replace with your actual username, password, and item ID
username = 'your_username'
password = 'your_password'
feature_layer_item_id = 'your_feature_layer_item_id'  # The item ID of the item you want to copy
portal_url = 'https://www.arcgis.com'

# Authenticate with ArcGIS Online
gis = GIS(portal_url, username, password)

# Access the hosted feature layer item
feature_layer_item = gis.content.get(feature_layer_item_id)

Use the clone_items method to create a deep copy of the feature layer item.

main.py
Use dark colors for code blocks

from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection

# Replace with your actual username, password, and item ID
username = 'your_username'
password = 'your_password'
feature_layer_item_id = 'your_feature_layer_item_id'  # The item ID of the item you want to copy
portal_url = 'https://www.arcgis.com'

# Authenticate with ArcGIS Online
gis = GIS(portal_url, username, password)

# Access the hosted feature layer item
feature_layer_item = gis.content.get(feature_layer_item_id)

# Use the `clone_items` method to create an entirely new copy of the feature layer item
cloned_items = gis.content.clone_items([feature_layer_item])

# Check the result of the clone operation
if cloned_items:
    print(f"Successfully cloned the item. New item ID: {cloned_items[0].id}")
else:
    print("Failed to clone the item.")

Add the following import statement to your code.

rest-js.js
Use dark colors for code blocks

import { ApiKeyManager } from '@esri/arcgis-rest-request';
import { getItem, addItem, getItemData, setItemData } from '@esri/arcgis-rest-portal';

Establish a connection to the portal.

rest-js.js
Use dark colors for code blocks

import { ApiKeyManager } from '@esri/arcgis-rest-request';
import { getItem, addItem, getItemData, setItemData } from '@esri/arcgis-rest-portal';

const apiKey = "YOUR_ACCESS_TOKEN";
const authentication = ApiKeyManager.fromKey(apiKey);

Get the item and associated data.

rest-js.js
Use dark colors for code blocks

import { ApiKeyManager } from '@esri/arcgis-rest-request';
import { getItem, addItem, getItemData, setItemData } from '@esri/arcgis-rest-portal';

const apiKey = "YOUR_ACCESS_TOKEN";
const authentication = ApiKeyManager.fromKey(apiKey);

// Get the feature layer item details
const itemDetails = await getItem(featureLayerItemId, { authentication });
const itemData = await getItemData(featureLayerItemId, { authentication });

Define properties of a new item and add the new item using the addItem method.

import { ApiKeyManager } from '@esri/arcgis-rest-request';
import { getItem, addItem, getItemData, setItemData } from '@esri/arcgis-rest-portal';

const apiKey = "YOUR_ACCESS_TOKEN";
const authentication = ApiKeyManager.fromKey(apiKey);

// Get the feature layer item details
const itemDetails = await getItem(featureLayerItemId, { authentication });
const itemData = await getItemData(featureLayerItemId, { authentication });

// Create a new item by copying details from the existing item
const newItem = await addItem({
  item: {
    title: `Copy of ${itemDetails.title}`,
    type: itemDetails.type,
    description: itemDetails.description,
    tags: itemDetails.tags,
    snippet: itemDetails.snippet,
    extent: itemDetails.extent,
    spatialReference: itemDetails.spatialReference,
    typeKeywords: itemDetails.typeKeywords,
    url: itemDetails.url, // Include the URL to retain the feature service URL
  },
  authentication,
});

Set the underlying data for the newly added item.

    typeKeywords: itemDetails.typeKeywords,
    url: itemDetails.url, // Include the URL to retain the feature service URL
  },
  authentication,
});

// Set the data for the new item
await setItemData({
  id: newItem.id,
  authentication,
  data: itemData,
});
console.log(`Successfully cloned the feature layer. New item ID: ${newItem.id}`);
