FeatureSharingDraft—ArcGIS Pro

Zusammenfassung

The FeatureSharingDraft class allows you to create a service definition draft file (.sddraft) for a web feature layer that copies all data to either ArcGIS Enterprise or ArcGIS Online. To configure the properties of a web feature layer that references registered data, modify the MapImageSharingDraft class to include a feature layer.

Diskussion

To create the FeatureSharingDraft class object, use the map class function getWebLayerSharingDraft and set the service_type parameter to FEATURE. The FeatureSharingDraft class object can then be configured by setting service level properties and metadata properties.

Hinweis:

Wenn Metadateneigenschaften (credits, description, summary, tags und useLimitations) nicht festgelegt wurden oder aus leeren Zeichenfolgen bestehen, nutzt das Web-Layer-Element Metadaten aus der Karte oder dem Layer, abhängig davon, was freigegeben wurde. Weitere Informationen dazu, welche Quelle Web-Layer für Metadaten verwenden, finden Sie unter Web-Layer-Metadaten.

After the FeatureSharingDraft class object has been configured, it can be saved to a service definition draft file (.sddraft) using the exportToSDDraft function. It can then be staged and shared to either ArcGIS Enterprise or ArcGIS Online using the Stage Service and Upload Service Definition tools. For more information, see Introduction to arcpy.sharing.

Code samples are available for the following:

Eigenschaften

Eigenschaft	Erläuterung	Datentyp
allowExporting (Lesen und schreiben)	A Boolean that determines whether users can export the web layer to different formats.	Boolean
checkUniqueIDAssignment (Lesen und schreiben)	A Boolean that indicates whether your map is analyzed to confirm that the Allow assignment of unique numeric IDs for sharing web layers option in Map Properties is enabled. For more information, see Assign layer IDs.	Boolean
credits (Lesen und schreiben)	A string that represents the credits.	String
description (Lesen und schreiben)	A string that represents the description.	String
offline (Lesen und schreiben)	A Boolean that determines whether to use a portal connection. If offline is set to False, you must be signed in to a portal to create a service definition draft file (.sddraft) using the exportToSDDraft function. If offline is set to True, a service definition draft file can be created without being signed in to a portal.	Boolean
overwriteExistingService (Lesen und schreiben)	A Boolean that determines whether to overwrite an existing web layer.	Boolean
portalFolder (Lesen und schreiben)	A string that represents the name of a portal folder to which you want to publish the web layer. The default folder is your root folder in My Content.	String
serverType (Schreibgeschützt)	Returns a string representing the server type as specified when the sharing draft was created from the getWebLayerSharingDraft function from the map class. The only possible value returned from serverType for a FeatureSharingDraft is HOSTING_SERVER. A serverType of HOSTING_SERVER indicates support for sharing to ArcGIS Enterprise or ArcGIS Online.	String
serviceName (Lesen und schreiben)	A string that represents the name of the web layer. This is the name people will see and use to identify the web layer. The name can only contain alphanumeric characters and underscores. No spaces or special characters are allowed. The name cannot be more than 120 characters.	String

Codebeispiel

Publish a web feature layer to a portal folder

The following script creates a web feature layer service definition draft file (.sddraft) for a map and sets metadata and export data properties. The web feature layer is published to a folder in either ArcGIS Online or ArcGIS Enterprise. Portal information is obtained from the SignInToPortal function.

import arcpy
import os

# Sign in to portal
arcpy.SignInToPortal("https://www.arcgis.com", "MyUserName", "MyPassword")

# Set output file names
outdir = r"C:\Project\Output"
service_name = "FeatureSharingDraftExample"
sddraft_filename = service_name + ".sddraft"
sddraft_output_filename = os.path.join(outdir, sddraft_filename)
sd_filename = service_name + ".sd"
sd_output_filename = os.path.join(outdir, sd_filename)

# Reference map to publish
aprx = arcpy.mp.ArcGISProject(r"C:\Project\World.aprx")
m = aprx.listMaps('World')[0]

# Create FeatureSharingDraft and set metadata, portal folder, and export data properties
server_type = "HOSTING_SERVER"
sddraft = m.getWebLayerSharingDraft(server_type, "FEATURE", service_name)
sddraft.credits = "These are credits"
sddraft.description = "This is description"
sddraft.summary = "This is summary"
sddraft.tags = "tag1, tag2"
sddraft.useLimitations = "These are use limitations"
sddraft.portalFolder = "my folder name"
sddraft.allowExporting = True

# Create Service Definition Draft file
sddraft.exportToSDDraft(sddraft_output_filename)

# Stage Service
print("Start Staging")
arcpy.StageService_server(sddraft_output_filename, sd_output_filename)

# Share to portal
print("Start Uploading")
arcpy.UploadServiceDefinition_server(sd_output_filename, server_type)

print("Finish Publishing")

Overwrite a web feature layer

The following script overwrites a web feature layer. If the service name already exists, the service will be overwritten. Otherwise, a new service will be created.

import arcpy
import os

# Sign in to portal
arcpy.SignInToPortal("https://www.arcgis.com", "MyUserName", "MyPassword")

# Set output file names
outdir = r"C:\Project\Output"
service_name = "FeatureSharingDraftExample"
sddraft_filename = service_name + ".sddraft"
sddraft_output_filename = os.path.join(outdir, sddraft_filename)
sd_filename = service_name + ".sd"
sd_output_filename = os.path.join(outdir, sd_filename)

# Reference map to publish
aprx = arcpy.mp.ArcGISProject(r"C:\Project\World.aprx")
m = aprx.listMaps('World')[0]

# Create FeatureSharingDraft and set overwrite property
server_type = "HOSTING_SERVER"
sddraft = m.getWebLayerSharingDraft(server_type, "FEATURE", service_name)
sddraft.overwriteExistingService = True

# Create Service Definition Draft file
sddraft.exportToSDDraft(sddraft_output_filename)

# Stage Service
print("Start Staging")
arcpy.StageService_server(sddraft_output_filename, sd_output_filename)

# Share to portal
print("Start Uploading")
arcpy.UploadServiceDefinition_server(sd_output_filename, server_type)

print("Finish Publishing")

Set create and sync capabilities

The following script creates a web feature layer service definition draft file (.sddraft). It then sets the create and sync capabilities on the web feature layer by modifying the service definition draft file using the xml.dom.minidom standard Python library. The modified service definition draft file is then staged and published to a portal.

import arcpy
import os
import xml.dom.minidom as DOM

# Sign in to portal
arcpy.SignInToPortal("https://www.portal.domain.com/webadaptor",
                     "MyUserName", "MyPassword")

# Set output file names
outdir = r"C:\Project\Output"
service_name = "FeatureSharingDraftExample"
sddraft_filename = service_name + ".sddraft"
sddraft_output_filename = os.path.join(outdir, sddraft_filename)
sd_filename = service_name + ".sd"
sd_output_filename = os.path.join(outdir, sd_filename)

# Reference map to publish
aprx = arcpy.mp.ArcGISProject(r"C:\Project\World.aprx")
m = aprx.listMaps('World')[0]

# Create FeatureSharingDraft
server_type = "HOSTING_SERVER"
sddraft = m.getWebLayerSharingDraft(server_type, "FEATURE", service_name)

# Create Service Definition Draft file
sddraft.exportToSDDraft(sddraft_output_filename)

"""Modify the .sddraft file to enable create and sync"""
# Read the .sddraft file
doc = DOM.parse(sddraft_output_filename)

# Find all elements named TypeName
# This is where the additional layers and capabilities are defined
typeNames = doc.getElementsByTagName('TypeName')
for typeName in typeNames:
    # Get the TypeName to enable
    if typeName.firstChild.data == "FeatureServer":
        extension = typeName.parentNode
        for extElement in extension.childNodes:
            if extElement.tagName == 'Definition':
                for propArray in extElement.childNodes:
                    if propArray.tagName == 'Info':
                        for propSet in propArray.childNodes:
                            for prop in propSet.childNodes:
                                for prop1 in prop.childNodes:
                                    if prop1.tagName == "Key":
                                        if prop1.firstChild.data == 'webCapabilities':
                                            if prop1.nextSibling.hasChildNodes():
                                                prop1.nextSibling.firstChild.data = "Create,Sync,Query"
                                            else:
                                                txt = doc.createTextNode("Create,Sync,Query")
                                                prop1.nextSibling.appendChild(txt)

# Write to the .sddraft file
f = open(sddraft_output_filename, 'w')
doc.writexml(f)
f.close()

# Stage Service
print("Start Staging")
arcpy.StageService_server(sddraft_output_filename, sd_output_filename)

# Share to portal
print("Start Uploading")
arcpy.UploadServiceDefinition_server(sd_output_filename, server_type)

print("Finish Publishing")

Create and publish an offline service definition

The following script creates an offline service definition and publishes it as a web feature layer.

import arcpy
import os

# Set output file names
outdir = r"C:\Project\Output"
service_name = "FeatureSharingDraftExample"
sddraft_filename = service_name + ".sddraft"
sddraft_output_filename = os.path.join(outdir, sddraft_filename)
sd_filename = service_name + ".sd"
sd_output_filename = os.path.join(outdir, sd_filename)

print("Finish Publishing")

Analyze to confirm map is set to allow assignment of unique numeric IDs

The following script creates a web feature layer service definition draft file (.sddraft) that enables the checkUniqueIDAssignment property. The service definition draft file is analyzed during staging. If the map is not set to allow assignment of unique numeric IDs for sharing web layers, analyzer error 00374 is returned and a message is printed. For more information, see Assign layer IDs.
