🔍 Code Extractor

A collection class that manages and provides access to AppRoleAssignment entities, inheriting from EntityCollection to handle groups of application role assignments.

Purpose

AppRoleAssignmentCollection serves as a container and manager for AppRoleAssignment objects within the Office 365 directory services. It provides collection-level operations for managing application role assignments, such as querying, adding, and removing role assignments. This class follows the collection pattern used throughout the Office 365 SDK to handle multiple entities of the same type with consistent CRUD operations and query capabilities.

Source Code

class AppRoleAssignmentCollection(EntityCollection):
    def __init__(self, context, resource_path=None):
        super(AppRoleAssignmentCollection, self).__init__(
            context, AppRoleAssignment, resource_path
        )

Parameters

Parameter Details

context: The client context object that provides the connection and authentication information needed to communicate with the Office 365 service. This context maintains the session state and handles API requests.

resource_path: Optional string parameter specifying the URL path to the resource endpoint for this collection. If None, the path will be determined automatically based on the parent entity. This allows for flexible resource location within the Office 365 API hierarchy.

Return Value

Instantiation returns an AppRoleAssignmentCollection object that can be used to interact with a collection of AppRoleAssignment entities. The collection provides methods inherited from EntityCollection for querying, filtering, and manipulating the role assignments. Methods typically return the collection itself for chaining operations, or individual AppRoleAssignment objects when accessing specific items.

Required Imports

from office365.directory.applications.roles.assignment import AppRoleAssignment
from office365.entity_collection import EntityCollection

Usage Example

from office365.runtime.auth.client_credential import ClientCredential
from office365.graph_client import GraphClient
from office365.directory.applications.roles.assignment_collection import AppRoleAssignmentCollection

# Setup authentication
credentials = ClientCredential('client_id', 'client_secret')
client = GraphClient(credentials)

# Get a user or service principal
user = client.users.get_by_id('user_id')

# Access the app role assignments collection
role_assignments = user.app_role_assignments

# Load the collection from the server
role_assignments.get().execute_query()

# Iterate through assignments
for assignment in role_assignments:
    print(f"Role ID: {assignment.app_role_id}")
    print(f"Resource: {assignment.resource_display_name}")

# Add a new role assignment
new_assignment = role_assignments.add(
    principal_id='user_id',
    resource_id='service_principal_id',
    app_role_id='role_id'
)
client.execute_query()

Best Practices

• Always call execute_query() on the client context after performing operations to commit changes to the server
• Use get() method to load the collection from the server before iterating through items
• Handle authentication errors and ensure proper credentials are configured before instantiating
• The collection is typically accessed through parent entities (users, service principals) rather than instantiated directly
• Check for appropriate API permissions before attempting to add or remove role assignments
• Use filter() and select() methods inherited from EntityCollection to optimize queries and reduce data transfer
• The collection maintains state between operations, so be aware that multiple operations may be batched
• Consider using expand() to load related entities in a single request for better performance
