Publishing, revising, and withdrawing record lists

This example shows how to connect to Granta MI and perform advanced operations on record lists, such as publishing, withdrawing, and revising a list. For more information about the concepts discussed here, see the Help in the Granta MI Favorites app.

Note

Running this notebook requires permissions to request publication of, to publish, and to revise a record list. Contact your Granta MI administrator for more information.

Connect to Granta MI and create a record list

Import the Connection class and create the connection. See the Getting started example for more details.

from ansys.grantami.recordlists import Connection

connection = Connection("http://my_grantami_server/mi_servicelayer").with_autologon()
client = connection.connect()

Create a record list for use in this example.

example_list = client.create_list(
    name="Example list",
    description=f"Created by example 01_Advanced_usage",
)
example_list

<RecordList name: Example list>

Record lists include two properties describing two aspects of their status: whether they are awaiting approval to be published, and whether they are currently published. Define a function to display the status properties.

def print_status(record_list):
    print(f"Awaiting approval: {record_list.awaiting_approval}")
    print(f"Published: {record_list.published}")


print_status(example_list)

Awaiting approval: False
Published: False

Publish a record list

A record list is proposed for publication by calling the request_list_approval method with the record list to be published.

updated_list = client.request_list_approval(example_list)

print_status(updated_list)

Awaiting approval: True
Published: False

Publish the record list by using the publish_list method.

updated_list = client.publish_list(example_list)

print_status(updated_list)

Awaiting approval: False
Published: True

Revise a record list

A published record list cannot be modified directly. Instead, first create a revision of the published record list using the revise_list method. This creates an editable copy of the original record list (a list revision), and leaves the original record list unchanged.

revision_list = client.revise_list(example_list)

print_status(revision_list)

Awaiting approval: False
Published: False

The record list revision includes a property tracking the parent record list:

print(f"Is revision: {revision_list.is_revision}")
print(f"Parent identifier: {revision_list.parent_record_list_identifier}")

Is revision: True
Parent identifier: 58901a1f-f1e5-41e0-a122-dbf964fc785b

Modifications made to the list revision are applied to the original list when the list revision is published. Once the original list is updated, the list revision is deleted and is no longer available.

updated_revision_list = client.update_list(revision_list, notes="Added during revision process")
updated_revision_list = client.request_list_approval(updated_revision_list)
updated_original_list = client.publish_list(updated_revision_list)

# When publishing a revision list, the returned object is the updated parent list.
# Check the notes of the list to confirm the revisions were made successfully.
print(f"Notes: {updated_original_list.notes}")
print(f"Is published: {updated_original_list.published}")

Notes: None
Is published: True

Withdraw a record list

When a record list is in the published state, calling request_list_approval requests the withdrawal of that list.

updated_list = client.request_list_approval(example_list)

print_status(updated_list)

Awaiting approval: True
Published: True

Use the unpublish_list method to withdraw a record list.

updated_list = client.unpublish_list(example_list)

print_status(updated_list)

Awaiting approval: False
Published: False
