Purpose

This function serves as a controller endpoint to fetch a specific approval cycle by its UID. It acts as a wrapper around the internal controller's get_cycle_by_uid method, providing logging capabilities through the log_controller_action decorator. This is typically used in document management workflows to retrieve approval cycle details, status, and associated metadata for display or further processing.

Source Code

def get_approval_cycle(approval_uid: str) -> Optional[Dict[str, Any]]:
    """Get an approval cycle by uid."""
    return _controller.get_cycle_by_uid(approval_uid)

Parameters

Name Type Default Kind
approval_uid str - positional_or_keyword

Parameter Details

approval_uid: A string representing the unique identifier (UID) of the approval cycle to retrieve. This should be a valid UUID string that corresponds to an existing ApprovalCycle record in the database. The UID is typically generated when an approval cycle is created and serves as the primary lookup key.

Return Value

Type: Optional[Dict[str, Any]]

Returns an Optional[Dict[str, Any]], which means it can return either a dictionary containing the approval cycle data or None. If the approval cycle is found, the dictionary will contain fields such as cycle status, associated document information, approver assignments, timestamps, and other approval cycle metadata. If no approval cycle exists with the given UID, the function returns None.

Dependencies

  • CDocs
  • typing
  • datetime
  • logging
  • traceback
  • uuid

Required Imports

from typing import Dict, Any, Optional
from CDocs.controllers import log_controller_action

Usage Example

from CDocs.controllers.approval_controller import get_approval_cycle

# Retrieve an approval cycle by its UID
approval_uid = '550e8400-e29b-41d4-a716-446655440000'
cycle_data = get_approval_cycle(approval_uid)

if cycle_data:
    print(f"Approval cycle status: {cycle_data.get('status')}")
    print(f"Document ID: {cycle_data.get('document_id')}")
    print(f"Created at: {cycle_data.get('created_at')}")
else:
    print(f"No approval cycle found with UID: {approval_uid}")

Best Practices

  • Always check if the returned value is None before accessing dictionary keys to avoid AttributeError
  • Ensure the approval_uid parameter is a valid UUID string format before calling this function
  • This function is decorated with log_controller_action, so all calls will be logged automatically
  • Use this function within proper error handling blocks to catch potential database connection issues
  • Consider implementing permission checks before calling this function if user authorization is required
  • The function relies on the _controller object being properly initialized in the module scope
